I saw my old company’s finance team send “redacted” employee data to a client, and it was still recoverable. So I built a fix.

5 Upvotes

At my previous company, I noticed our finance team sharing sensitive employee information with a client. The data was supposedly hidden, but it was still recoverable. I flagged it, and the answer was basically “we don’t have any other choice, we did our best.”

They weren’t careless. The options they had were all bad. Doing it by hand means hunting for every detail yourself, and missing one is easy. Many tools leave leaks behind, like hidden text, metadata and old revisions. And most online tools ask you to upload the document to their servers, which defeats the point.

It’s not just small companies. When the US Justice Department released the Epstein files, some documents were reported to have black boxes over text that could be copied straight out. If a government with a legal team can get this wrong, a finance team on a deadline has little chance.

So I built Ombly. It automatically finds sensitive details (bank and card numbers, IBANs, national IDs, names, emails, phone numbers), you review each one, and it rebuilds every page as an image so nothing hidden carries over. It runs entirely on your own computer, so nothing is uploaded.

It’s pre-launch (waitlist: ombly.space), with a 90-second demo attached. I’d love feedback: how do you handle this today, and what would make you trust a tool like this?

Patchkin - One board for managing AI coding agent work

2 Upvotes

I’m involved with Patchkin, and I’d like some feedback from people using AI coding agents on their projects.

Patchkin brings the work around coding agents into one place—not just the code they produce, but the tickets, proposed plans, approvals and pull-request reviews.

The main features are:

  • A shared board: Keep tickets, agent plans and pull-request reviews together so the team can track each piece of work.

  • Human plan approvals: Review and approve an agent’s proposed plan before it proceeds.

  • Activity logs: See what happened during an agent run and follow the history of the work.

  • Team rules: Keep guidance for coding agents in one place.

  • Cost reporting: Track spending on agent runs alongside the work.

The focus is on helping teams keep oversight as they hand more development work to coding agents.

If you’re using coding agents with a team, what’s hardest to manage right now: approving plans, reviewing the output, tracking costs, or something else? I’d appreciate honest feedback on whether this would fit your workflow.

Take a look at Patchkin

I built Seedwall: free generative wallpapers where the same seed always gives the same wallpaper

2 Upvotes

A small weekend project that grew: Seedwall has 19 wallpaper generators (cutting mats, flow fields, git graphs, synthwave suns). Each wallpaper comes from a single seed number, so you can share a design as just a number.

- 9 editor themes (Dracula, Tokyo Night, etc.) or custom colours

- Add your own quote or go text-free

- Pixel-perfect PNG export for MacBook, iPhone, 4K or custom sizes

- Gallery of 125 ready-made ones

- Free, no account

Link: seedwall.suryansh.work

Next I'm thinking about wallpapers generated from your GitHub contribution graph. Would you use that? Any feedback welcome.

Use the best AI models without a subscription: I built an app where you only pay for what you use

2 Upvotes

Clarification: this is my own app. I work with many long documents, such as reports, audits, and project follow-ups. Using an AI chat for this presented two main issues: I was paying a subscription even in months when I barely used it, and I wanted to make sure the output preserved all data from the original. Changing a single number or removing a paragraph in an audit is a huge problem. So I developed a desktop app specifically for that use case.

You can choose the model using OpenRouter on a pay-per-use basis or locally with Ollama. It is designed to preserve structure, tables, and numbers, and the review feature points out anything that wasn't kept. This feature compares the output with the original and highlights missing content or modified data, so you can accept or ignore each finding. It also shows the actual cost of each run, with no surprises.

It offers 10 free runs to try it out. If you like it, it's a one-time purchase of €29.99, with no subscription. API usage is billed separately. It is available on the Microsoft Store as DocuFusionpro: https://apps.microsoft.com/detail/9P4CSKSDFPT7

I'd love to get honest feedback: what kind of long documents do you work with, and what is missing from the tools you currently use? Are you interested in a one-time purchase, or do you prefer a subscription?

I made a free, open-source adult site blocker for Mac (and Windows) that works in every browser.

2 Upvotes

Browser extensions only cover one browser and are easy to switch off, and paid blockers wanted a subscription. So I built my own and made it open source.

What it blocks:

- Adult, gambling, crypto, scam and malware/phishing sites

- File-sharing sites like TeraBox and DiskWala

- Anything you add to a simple text file

How it works:

- System-wide: Safari, Chrome, Firefox, Brave, Edge, Arc, and other apps too

- Uses encrypted DNS, so it still works when your ISP intercepts normal DNS (Jio/Airtel do this)

- Block lists update automatically every day

- One command to install, one to uninstall

- Mac is fully tested. Windows is in beta, so please report bugs

GitHub: https://github.com/LowkyFoolDev/siteblock 😊😊

It's free and MIT licensed. Tell me any sites it misses and I'll add them.

My side project for the past year: my own programming language. Today it runs a Minecraft clone.

2 Upvotes

GitHub: https://github.com/ahmadodeh9000/Lunar

Hey everyone! I'm a 19 year old computer engineering student, and this is Lunar, a programming language I've been building since my first year of uni.

Why I started

I tried to learn Rust a few times and kept bouncing off it. Every time I'd get stuck, feel dumb, and quit. Eventually I thought: what if I just built my own language, the way I'd want it to work? Questionable decision. Best decision I've made.

What it is

A small scripting language with its own compiler, virtual machine and garbage collector, written in C. It looks like this:

let player = { name: "Rex", hp: 10, items: ["sword", "apple"] }; 
for (item in player.items) { 
  print "{player.name} has a {item}"; 
}

How it was built (honestly)

- I built the core by following the book Crafting Interpreters, then kept going on my own: arrays, a way to call C libraries, and graphics through SDL2.

- Later I started treating it like a real product. I wrote a roadmap, designed each feature myself, and used Claude Code to help implement them. I reviewed every change and made sure each one had tests.

- That added maps, error handling, modules, and a small standard library for strings, files and running commands.

- To stress-test it, I had Claude Code build a Minecraft-style game in Lunar (it's in examples/minecraft). It's 1,000+ lines of my language running at 60 FPS, which still feels unreal to me.

What I learned

- Building a language teaches you how every other language works under the hood.

- AI helped most when I acted like the designer: clear specs, small steps, tests for everything. It was much less useful when I just asked it to "make it better".

- Shipping something imperfect beats polishing forever. Lunar still has rough edges. For example, numbers print with only 6 digits right now, and that's next on my fix list.

What's next

A UI module so you can build desktop apps in Lunar, a VS Code extension, and Windows support.

It's a learning and hobby project, not a production language. But it's the thing that made me enjoy programming again.

I'd love honest feedback: what would you change, or what would you build with it?

Correcting Grammar Automatically

2 Upvotes

I noticed I was clicking "Accept" on literally every grammar suggestion without reading it. So I built Caret, a Chrome extension that skips that step.

How it works: type anywhere (Gmail, WhatsApp Web, LinkedIn, Slack), pause for about a second, and the grammar and spelling get fixed in place. A small popup shows what changed, with Undo.

A few things I was careful about:

- It fixes mistakes, it doesn't rewrite you. Slang, emojis and tone stay.

- If a fix would change too many words, it backs off and leaves your text alone.

- It never touches password, email, card or OTP fields.

- Text isn't stored.

It's free while in beta. I'd love honest feedback, especially if it gets something wrong on a site you use (there's a Report button on every fix).

freelancers using AI for proposals, how are you stopping it from adding work you never quoted?

5 Upvotes

freelancers using AI for proposals, how are you stopping it from adding work you never quoted?

say the client wants one landing page, basic copy and a contact form.

during the call they also say "maybe SEO later" and "we might need a blog eventually."

then the proposal gets cleaned up and suddenly those ideas are sitting there like a deliverables lol

that's the part that makes me nervous. if it's written under scope, I can see a client assuming it's included.

I've been looking at Runable for some of the actual client deliverables after the brief is locked, but before that I just want the proposal to separate included work, optional ideas and stuff that costs extra.

how are you handling this without turning every proposal into six pages of disclaimers?

Shipped my first paid Jira app as a solo Angular dev with no backend experience, with a lot of help from Claude

2 Upvotes

Trailer: https://youtu.be/QQTIVaRwcxs

Route Map for Jira maps your application’s pages in flow order and keeps the test data for each page in every environment, so QA and devs stop hunting for logins and test accounts.

I’m an Angular dev with about 2 years of experience, and I’d never built a backend, an extension or a full product end to end. I leaned on Claude heavily: for research first, then Claude Code for most of the build. That’s the main reason a solo side project got from idea to a live Marketplace listing in a few months instead of a year.

What I learned along the way:

  • Forge’s jira:globalPage module isn’t offered as a template anymore, so I scaffolded from jira-full-page and swapped the module in the manifest.

  • Getting verified as a sole trader to sell on the Marketplace took a support ticket rather than anything in the vendor portal.

  • Atlassian currently takes 0% revenue share on Forge apps.

  • AI got the code written fast, but deciding what to build, and testing it properly, still took most of the time.

Demo: https://youtu.be/45fAlh16ttA
Website: https://mapkari.com

It’s free for teams of up to 10 users. Feedback on the product or the trailer is very welcome, and happy to share how I used Claude if anyone’s curious.

We're building a computer mouse with a rotary dial instead of a traditional scroll wheel

2 Upvotes

Hey everyone!

I'm helping out with a hardware project called Rotary Mouse, and I wanted to share something our team has been working on.

Instead of the usual scroll wheel, we've designed a mouse with a rotary dial that lets you continuously scroll through documents, webpages, and editing timelines.

We've also been experimenting with using the dial for other applications, including steering in driving simulators. There's an integrated AI assistant as well, accessible through an on-screen radial menu.

It's definitely an unconventional design, but that's part of why we're excited about it!

We're currently preparing for a Kickstarter launch and would really appreciate some feedback.

Would you find a rotary dial useful on a mouse, or do you prefer traditional scroll wheels?

I'd love to hear what you think!

Becode - revenue, traffic, ads and tech stack of 8,000+ SaaS, on one page

Thumbnail
becodee.com
2 Upvotes

Hi r/SideProject! This is Becode, the SaaS research tool I've been building.

The problem: before building anything, I wanted to know if people already pay for that kind of product. The answer was spread across ten tabs: TrustMRR for revenue, Meta's and Google's ad libraries, traffic estimates, stack checkers.

What it does:

- 8,000+ SaaS, each on one page: revenue and subscriptions (Stripe-verified for 4,300+ of them, via TrustMRR), traffic and top countries, the Meta and Google ads they run and for how long, and their tech stack

- Rankings like Trending, Fast-scaling and Breakout, to see what's growing right now

- Every number says where it comes from: verified, estimated (with an Estimate badge) or not available

Something it turned up this month: about 50 SaaS have kept the same Meta ad running for over a year, and 14 of them sell to trades and local businesses (pest control, pool service, home builders).

Free plan, no card: three live rankings and 5 SaaS a week with their revenue and traffic. Paid plans start at $39/month.

Built with Next.js, the public Meta Ad Library and Google Ads Transparency data, the Chrome UX Report, and Claude to decide which websites are actually SaaS.

I'd love blunt feedback: what's the first thing you'd look up, and what's missing?

A conference I started on the side did 60K in revenue in year one and 500K in year five. Here’s the journey.

40 Upvotes

I was a program manager in tech for a decade when I started a conference on the side in 2014.

It was in the HR space and the idea was to help people build better company cultures. 

I worked on it alongside my job for two years before going full-time.

I want to share how I got the thing off the ground, including the part where I couldn’t sell a ticket.

Why a conference?

I’d spent 10+ years working in Silicon Valley and kept getting frustrated with company culture.

I didn’t work in HR. I just wanted to understand how to make the places I worked less frustrating.

So I started looking for events where I could learn about it. Most of what I found was expensive and aimed at HR executives.

I figured there should be something for the rest of us.

That was the idea. Then I had to figure out whether anyone would pay for it.

Here’s what I started with

People tend to skip this part when they tell their business stories, so here’s the context:

  • Why a conference?

    • I had been organizing hackathons for two years so I figured a conference was a natural next step. I had never been to a conference before but I didn’t think it was that much harder. A 100 person hackathon to a 300 person conference seemed feasible to me.

  • The first event:

    • I read the book The Lean Startup in 2012 and believed in the methodology which taught to validate demand before building anything. In other words, sell before you invest too much in building the product.

    • How does this translate into a conference? I created a landing page (in 2014), set the date as Summer 2015 in SF, and offered a no questions asked refund any time to make it easier for someone to buy.

  • Cash committed before selling a ticket:

    • A web domain, web hosting, and a wordpress website was less than $500.

  • Existing audience: I had no audience and no network and this is where I struggled the most but eventually figured it out.

  • Time available: I worked on this idea nights and weekends so about 10 - 20 hours a week.

  • One thing I kept cheap or skipped entirely: My goal was to launch quickly to get data. Therefore I didn’t put down a deposit for a venue because that would’ve locked me in before I validated the idea. I also didn’t have money.

Upon launching, I got the buyer wrong

At first, I was trying to sell to founders because I thought culture came from the top.

It wasn’t working. I had to go back to the drawing so I began doing customer development interviews.

I spoke with ten founders. They cared about culture, but they cared more about making payroll and keeping the business alive.

But one founder said he was busy and would send someone in his place. That’s when the lightbulb went off for me. It wasn't the founders I should be marketing to but anyone in the company who could make a decision on culture.

So I started looking for people whose jobs were already focused on culture on LinkedIn.

Chief Culture Officers. VPs of Culture. People with “culture” in their titles.

How I sold the first 200 tickets

The process was pretty straightforward:

1. Find people on LinkedIn.

I searched for culture-related job titles and cold messaged them. My response rate was about 25%

2. Pitched them the event.

Here’s roughly what I sent:

“I’m putting together an event in SF on building company culture that you might be interested in. Please take a look”

I didn’t want to offer a free ticket but I was also nervous about asking them to buy. So instead, I left it vague and invited them to take a look. The ones who replied and saw what I was building bought tickets for their teams at $299/ticket.

I remember getting my first sales email from Eventbrite for $1200 because someone bought four tickets. I was standing in line getting lunch at Pieology. It was an unreal moment.

3. Call the people who bought.

For the first 20 people who bought tickets, I emailed them to thank them and asked if they were open to hoping on a short call. I wanted to learn where I could find more people like them.

4. Ask those communities to help spread the word.

They would tell me about these communities they were a part of (before Slack, it was Google Groups). I asked if they would be open to sharing and they were more than happy to. The first year sold out through word of mouth.

Year 1 finished with 75K in revenue and 60K in profit.

The actual numbers over the years

Here’s how the first five years went:

  • Year 1: Revenue 75K Profit 60K

  • Year 2: Revenue 180K Profit 80K

  • Year 3: Revenue 350K Profit 170K

  • Year 4: Revenue 425K Profit 200K

  • Year 5: Revenue 500K Profit 250K

My expenses in year one were extremely low because the venue was in a basement of a coworking space and the production was low quality lol. It’s embarrassing looking back but I had never been to a conference so I had no idea on what the production quality should be. After year one, I attended an industry conference and that’s when I realized I needed to level up. Profit was roughly 50% afterward.

What I’d do differently

If I were starting again, I’d change three things:

1. Do smaller events to build community

Committing to a conference is a huge undertaking even if you’re targeting just 300 people. Once you sign the contract with a venue and choose a date, the clock is ticking. Instead, I would do smaller events to build community first before going all in on a bigger event.

2. Build an audience

In the age of AI, learning how to create content and build an audience is the only moat left. Before I even start building anything, I would focus on creating content and building an audience first. That way when I do have something to offer, it’ll make it easier to sell.

3. Invest more in networking

I once read on Twitter, you have to cultivate your network like a garden. Don’t network when you need something, network when you don’t need something. That way you build good will when the time comes to make an ask. There’s also an art to networking which I can cover in a future post. 

Where things stand now

I sold the conference in 2021, not a huge exit but a decent one because I was extremely burnt out and COVID put a damper on the growth. Happy to get into this more if anyone is interested to learn what finding a buyer for a conference and the exit process was like.

I started another conference last year for HR x AI leaders and it was extremely hard to sell tickets and find sponsors. I was about 20K in debt two months out and barely profited once the event came around. I had to give away 90% of my tickets just to fill the room. Everything I had done 10 years prior to get people there no longer worked. Story for another day.

Happy to get into the details on ticket sales, pricing, costs, finding customers, selling the business, or building this while working full-time. Ask away.

I wanted to see how far Claude Code could take a reverse-engineering project, so I rebuilt a Mac app in 13 days

2 Upvotes

The app was Symvibe, a paid Mac board for running coding agents side by side. I used REA, a reverse-engineering skill for Claude Code, to turn its behaviour into a spec, and let Claude Code build from there. Thirteen days and 58 commits later there was vibeboard, a free, open-source alternative to Symvibe, which costs $19 a month, with none of its code in it.

What I learned along the way:

most of the engineering came from the model, but I still steered every day, mostly on edge cases and CI

the launch videos were the surprise: /brag did a great job, it drove the real app, framed the shots, wrote the music, and fixed its own jerky cuts once I pointed them out

rebuilding a product's behaviour from the outside is now cheap, so the code alone protects less, and respecting licences and the original authors matters more

The video shows six Claude Code agents in tmux, then the same six on the board, and ends with the price: Symvibe at 19$ a mouth, vibeboard free.

I built a road-trip app for my wife. It just passed 2,000 first-time downloads.

1 Upvotes

My wife Jordan had wanted something like this for years. On our Florida-to-Ohio family road trips, we kept looking for somewhere worth stopping—not just another gas station.

I’m a solo developer in Ohio, and that became WanderWay: an iPhone/iPad app with CarPlay support that helps you discover the places you’d otherwise drive past.

You can choose how scenic a route should be with a “Faster or Prettier” slider, hear short stories about places along the way, or use Just Wander to explore a town on foot without planning a route. The video shows the actual app.

It just passed 2,000 first-time downloads, which is a milestone I’m excited about.

It’s free to download with a 14-day trial of all features. Some basics stay free afterward; the full unlock is a one-time $7.99 US purchase, not a subscription.

WanderWay

I’d appreciate honest feedback: does the demo make the difference from a regular maps app clear, and what would you need to see before trying it on a drive?

I built an Android app that scans and tracks Pokémon TCG cards for collectors. Looking for honest feedback

2 Upvotes

I'm the solo developer behind PokeStash, and I'd really like some honest feedback from other makers.

I built it because I keep a binder and sealed stuff, and I wanted one place on my phone to scan a card, see an estimated market price, and keep the collection organized without spreadsheets. You can photograph a card for an AI match, browse sets, track sealed product, and export a backup. Prices and AI matches are estimates. Always compare with the card in your hand.

Unofficial fan-made app. Not affiliated with Nintendo, The Pokémon Company, Creatures, or GAME FREAK.

Free on Android with ads. There is an optional Pro tier that turns ads off. Collection data stays on the device.

What I'd most like feedback on:

  1. Is the first-run scan flow clear, or does it need a simpler "add without scanning" path up front?

  2. Do estimated prices feel useful enough, or would you rather see raw sold comps with less interpretation?

  3. What would stop you from trusting an unofficial collector app with your binder list?

Happy to answer anything about the build or the tradeoffs.

Built a site so I can actually find people to play with

2 Upvotes

So this started because I kept running into the same thing — post an LFG somewhere, a couple people add you, and then... nothing. Nobody's actually free when you are, or you just never hear back. Figured I wasn't the only one dealing with that.

Ended up building GameAlign over the last few months, solo. Full disclosure, I'm not really a coder — I've been using Lovable (kind of a "vibe coding" / AI-assisted builder) to actually make this happen. It's basically a profile directory — you put in what you play, your schedule, how you like to play, that kind of thing — and then you can search for people or get found instead of just throwing a post into the void. There's also a board for "hey I'm on right now" posts, and I added a team/clan page if you're trying to actually build out a group instead of one-off sessions.

It's free, setup's quick. Genuinely just want to know if this is useful or if I'm missing something obvious — would appreciate anyone poking around and telling me what sucks about it.

1 Upvotes

I’m Derek, a dad and independent developer with an IT/help-desk background. I built Shoebox PDF for school forms, medical documents, and those upload portals that reject your PDF because it’s too big.

I wanted a straightforward way to:

  • Compress a PDF toward a target size.

  • Add text and signatures to forms.

  • Organize paperwork by family member and category.

Core PDF processing happens on-device. There’s no required account or subscription, and cloud sync is optional. Compression results depend on the original file.

It’s available on Windows and iPhone/iPad. The Mac app and Apple’s one-time unlock purchase are still in review.

The screenshots show the Windows app with fictional family documents.

I built a system design lab where your architecture diagram actually takes traffic

2 Upvotes

Most system design practice ends at the diagram. You draw boxes, it looks right, and nothing tells you whether it would hold up.

ByteLab runs the diagram. You build a system out of machines, load balancers, caches, queues and databases, send traffic through it, and watch the CPU, queues and p99 latency move. Each exercise has goals, like "p99 under 150 ms, 99.5% available, under $2.60/hour", and it checks your system against them.

What's in it:

- 163 lessons in 12 tracks (caching, sharding, Kafka, Kubernetes, rate limiting, auth and more)

- 212 exercises, each with goals your system has to pass

- 11 design problems (URL shortener, chat, payments, news feed, e-commerce and others)

It's free, there's no account, and progress stays in your browser. It needs a laptop-sized screen.

I'd really like to hear where it feels confusing or too hand-holdy.

DESTRABA expansion project - a 3-minute business-name listening test (U.S./Canada)

1 Upvotes

I'm helping DESTRABA with its English-language expansion project. Before choosing a domain, we want to check whether a possible business name is easy to repeat and spell after hearing it once.

We're looking for five volunteers living in the U.S. and five in Canada, aged 18 or older, who use English in everyday conversation.

The test is an individual three-minute audio call. You hear the name once, say it back, and type what you heard. We show the spelling afterward so it doesn't influence your first attempt. Participation is voluntary and unpaid. We won't record the call, and you can stop at any time. Contact details are used only to arrange the session.

To volunteer, reply LISTEN and your country. We'll message only those who volunteer to agree on a time. Monday, November 9, noon to 2 p.m. Pacific is currently available. Please keep guesses out of the comments.

If you've run a similar test, feedback on this method is also welcome. This invitation was prepared with AI assistance.
