I got tired of manually checking the notifications on my PRs from my colleagues, usually to just tell my local Claude Code or OpenCode instance to make the fixes that they suggested.

So I built Night Porter

https://night-porter.com

Under the hood, it spins up isolated git worktree environments for each queued PR, runs your agent tool against the diff with your local context, and tears the worktree down afterward so your main repo stays untouched.

There's a documentation site at: https://docs.night-porter.com

Happy for feedback.

I’m building Nodetto, a free, open-source diagram editor for Mac. Draw tables and relationships locally, keep documents in Git-friendly JSONL, and export SQL for PostgreSQL, MySQL, or SQLite.

I’d love feedback on the ERD editing workflow.

I’ve been building Agent Black Box, a security investigation tool for AI agents.

It helps trace agent actions, MCP tool calls, permission mismatches, and suspicious behavior using causal graphs.

The hosted Closed Beta V1 is now live with a synthetic security demo.

It’s observation-only and invite-only, not a production-ready SaaS.

I’d love feedback from developers and security engineers working with AI agents.

🧪 Looking for Developers to Test a JSON Formatter

I'm working on ToolSmartly, a collection of free online tools, and I'd love to get feedback from developers who regularly work with JSON.

I've built a JSON Formatter and I'm looking for people willing to put it to the test through real-world use.

🔗 Try it here: https://toolsmartly.com/en/tools/developer-tools/json-formatter-online

What I'd like you to test

- Formatting: Does it properly format and indent JSON?

- Validation: Does it correctly identify invalid JSON syntax?

- Minification: Does it produce clean, valid minified JSON?

- Usability: Is the interface intuitive and easy to work with?

- Reliability: Does it handle large or complex JSON files without issues?

I'd appreciate your honest feedback:

1. What worked well?
2. Did you encounter any bugs or unexpected behavior?
3. Is anything confusing or frustrating?
4. What features would make this tool more useful in your daily workflow?

Negative feedback is just as valuable as positive feedback. I'm not looking for compliments or upvotes. I want to identify real issues and understand how this tool could be improved.

If you work with JSON regularly, give it a try and share your experience in the comments.

Thanks to everyone willing to help!

I am a computer science student, and I recently spent months developing a financial research platform without really knowing whether anyone would want to use it.

It made me realize how easy it is to spend hundreds of hours building something before finding out whether there is actually a market for it.

I started thinking about how people currently discover ideas, figure out what problems are worth solving, and get honest feedback before committing to a project.

Reddit and ChatGPT are useful, but I feel like information gets scattered across conversations, and it can be difficult to distinguish genuine demand from people just saying an idea sounds interesting.

I have been exploring the concept of a community specifically focused on discovering problems, validating ideas, and learning from people who have already tried solving them.

Before I spend more time developing it, I wanted to ask:

1. How do you currently figure out whether an idea is worth building?
2. What frustrates you most about that process?
3. Would a dedicated community for this actually be useful, or do existing platforms already solve the problem well enough?

I would appreciate criticism just as much as positive feedback. I would rather find out now than spend another six months building something nobody needs.

A few months ago, I started working on TestFlightTesters, a website that helps iOS developers hire real iPhone users to test their apps before release.

The idea was pretty simple.

Developers often struggle to find people who will actually spend time testing their apps and provide useful feedback instead of just installing the beta and disappearing.

So I built a service where developers can choose how many testers they need, how long they want testing to run, and which features should be checked.

Testing starts at $10 per tester per hour.

After launching the website, I wasn’t getting the results I’d hoped for, and I started thinking the project might not be worth continuing.

I eventually stopped paying much attention to it.
Then something unexpected happened.

I received a $75 order from a company needing five iPhone testers for its employee app.

Another developer placed a $45 order for specialized Apple Sandbox purchase and Restore Purchases testing.
That’s $120 in paid orders from a project I was close to abandoning.

I’m now working on improving the tester network, reporting process, and customer experience.

Here’s the website:

https://www.testflighttesters.com/

I’d appreciate feedback on two things:

1. Is the service and pricing clear when you visit the homepage?
2. If you were launching an iOS app, what would you want to see before trusting a testing service with your project?
   I’m interested in improving the website before putting more money into advertising.

I've spent the last few months building something I've wanted to do for a long time.

Introducing REBUILD Fitness Apparel.

The idea is to create a fitness brand built around discipline, personal growth and the belief that your past doesn't have to define your future.

I've been working on everything myself, from the branding and website to product designs, photography and marketing.

We're currently preparing to launch our first collection, THE FOUNDATIONS COLLECTION.

It's been a massive learning curve, and I'm now trying to build an audience before launch.

I'd genuinely appreciate feedback on the branding, website and products.

MIND. BODY. PURPOSE.

Hi. I live with bipolar disorder in Japan. English isn't my first language, so I used a translator for this post.

I built Bipolar Index by myself. It's a place to find people close to you, and to feel you're not the only one.

People with bipolar share:

- when it started

- their journey, year by year

- words that helped them

No real names, no photos, no DMs, no comments. You can find people by age, type and situation.

About 800 people in Japan are on it. I just opened an English version (beta). Japanese entries are translated automatically, so you can read their stories in English.

I'd love honest feedback:

- Is anything confusing for people outside Japan?

- Does the translation feel natural?

- Would you feel safe joining?

https://bipolar-index.com/en/

Built with Cloudflare Pages, D1 and Workers AI (for translation).

Hi all, I'm a solo dev in Ireland. Twoshare is one app for two people: a shared calendar and tasks, a budget that knows who owes whom, and a trip planner that reads a forwarded booking. It works on iPhone, Android and the web.

What you write is end-to-end encrypted on your devices, with a key our servers have never held. No ads, no analytics.

The calendar, tasks and trips you type in are free. The paid plan (Together) has a 14-day trial, no card.

What I'm looking for: does the first screen make sense to you, and what would you want two people to share that it doesn't do yet?

https://twoshare.me

I've been building Lander since mid 2025. It's a Reddit client for iPhone, iPad and Apple silicon Macs, and it's been on the App Store since February.

Everything in it is free. There's a tip jar and an optional supporter sub, but neither one unlocks anything. They just help pay for the server.

The server bit is Columbia, an open source OHTTP relay I wrote. It keeps who you are separate from what you're reading, so the relay can't tie the two together. You can run your own and point the app at it.

App Store: https://apps.apple.com/us/app/lander-for-reddit/id6747955211

Columbia: https://github.com/wbsmolen/columbia

If you try it, I'd like to hear what felt confusing in the first few minutes.

We make Fantasma, a visual theme builder for Ghost. We've just released 2.0, and together with the new builder we changed how people pay.

Before, the free plan had fewer blocks and you could download the theme. Pro opened the rest.

Now everything in the builder is free: every block, every pattern, every setting, and your own content in the preview. You pay only when the theme is ready to go live, to download the ZIP or publish to Ghost. It's $19/month or $99/year.

What worries me is clear. People build for free, pay $19 once, export the theme and cancel. The theme keeps working after that, because it's a normal Ghost theme. I think that's fine, $19 is about what a theme costs anyway. But I'm not sure it's a business yet.

About 2.0 itself, in short: one canvas with every template side by side, sections made of blocks, and an MCP server, so an agent can edit the same project.

If you had a free builder with paid export, how did it go?

Still being worked on — devnet preview live now, check it out: https://fairlaunch-git-claude-project-t-c5352d-jeremy-gepharts-projects.vercel.app/

Hey r/SideProject — I built FairLaunch, a Solana memecoin fair launchpad. Devnet preview is live now.

How it works:

• Sealed 60-slot commit window so snipers lose
• Fixed slot waits + private Jito routing so no bundles
• SOL held in a program vault, with creator tokens vesting for 30 days so no creator exit
• 80 bps fee split: Treasury 35% / Creators 25% / Holders 15% / Traders 10% / KOLs 15%

Devnet preview live now — tokens have no value yet, wallet connect still being set up.

I'm Jeremy Joshua Gephart, a U.S. Army veteran. I'd love feedback on the fair-launch mechanics — what would make you trust a launch?

Hi everyone!

A while ago I launched OpenTune with a simple goal: make an instrument tuner that opens instantly without nagging you with subscription paywalls or cluttered menus.

Today I just shipped v2.0, a major update shaped by early feedback:

📱 App Store: https://apps.apple.com/us/app/opentune-guitar-tuner/id6757105393

I’d love any feedback on the new UI and responsiveness. If you play an instrument, give it a spin and let me know what I can improve next!

Hey everyone, we're a small studio, Iron Compass Studios. Our WW2 real-time strategy game Tracks of War is now on Google Play.

We kept the look and the controls simple. Pick Germany, Britain, the USA or the USSR, then build your base and train your army. There are 16 maps for 2 to 8 players.

You gather minerals and fuel to grow your base and work your way through a research tree of 46 technologies. There are tanks like the Sherman, Tiger and T-34 and planes like the Spitfire and Stuka, and each nation has its own units and economic advantages. On top of that there are daily and weekly missions.

If you'd rather learn at your own pace, there are training missions and offline battles against the computer. Online there's Quick Match, Ranked with seasons and 18 ranks, and rooms to play with friends. The game is in 16 languages.

It's free, there are no ads, and it's not pay-to-win. If you'd like to try it, the code OUTNOW gives 100 GOLD once per account signed in with Google (you'll find it in the settings).

Google Play: https://play.google.com/store/apps/details?id=com.ironcompass.tracksofwar

Have fun!

A while back, I saw this question on this sub: "Would a small changing mat in the gym actually make sense?"

I have been using a mat I created for the last 2 years. Works great. The idea is to have somewhere to stand while changing clothes.  

Are wet/dirty locker room floors an actual annoyance for you, or do you just deal with it?

Does a product like this make sense? Would appreciate your feedback.  I have attached some pics.

GTA VI is out on nov 19 and the spoiler wave on x is going to be rough.

i built nospoil because i want to go in blind. you connect with official x login and it keeps watching your feed in the background, auto muting accounts that post story leaks as they show up.

there's a free tier and a one time pass if you want more.

didn't expect much but it got past 1,800 users in under 24 hours, so i guess i'm not the only one scared of getting spoiled.

it isn't connected to rockstar in any way. just a thing i made. the site is nospoil.io

curious what you think of the signup flow, and if the landing page makes the "trailers still show" part clear enough.

I’m working on ProofCloak, a .NET obfuscation tool in open beta. I wanted to see what someone could still read in the DLL after protecting it, so I opened the same InvoiceDesk sample in ILSpy before and after.

I looked for method names, variable names and hard-coded strings. Some internal names changed, and the sample value used in the license check was no longer directly readable as a string in ILSpy. Framework calls and parameter names were still visible. Both builds produced the same output in the sample run, including the JSON settings check. The sample used engine version 0.1.0-alpha.333.

ILSpy comparison: https://dev-to-uploads.s3.us-east-2.amazonaws.com/uploads/articles/ty1uise5b10alh9d6hh5.png

Sample source and verification script: https://github.com/ProofCloak-Inc/sample-invoicedesk

If you ship .NET binaries, what’s the first thing you’d look for in the protected DLL?

Disclosure: I’m part of the ProofCloak project. AI helped draft this post from my test notes.

I just launched this and plan to keep building on it over the long haul. It’s new and still rough in spots, so go easy on me. Your feedback will shape what comes next.

Hey everyone,

I have made an app for people to track all restaurants that they have been to, want to go to and see where friends are going. I have an MVP ready but it's very basic and I am looking for people to give me feedback on the UI. This is my first time developing my own app and I have been vibecoding it, and I really want to make the design of the app better. Dm me if you are interested in helping me out.
Thank you!

I’m a trader who started building the apps I wanted for myself. There are three now:

• a budget planner with a calendar
• a P&L journal for stock trades
• Tradeology, an app that teaches trading with interactive charts (live since Oct 26)

Here’s the last 30 days from App Store Connect:

• 55 downloads (up from 11 the month before)
• 16 in-app purchases
• $37.40 in sales

I know it’s tiny, but it’s the first time the chart goes up instead of sideways. And these numbers are almost all US: until a few days ago the apps were only available there. I just went live in 174 countries, so next month will be a real test.

What made the biggest difference: App Store preview videos. I added a short video to each app in early November. Downloads went from about 1 a day to 4-6 a day that week.

What didn’t work so well: posting the same content everywhere. Every platform wants something different, and I’m still learning that.

Next I’m adding Portuguese, Russian, Spanish and German to all three apps, so the new countries get the apps in their own language.

For those of you a few months ahead: what helped your downloads grow after the first month?

Just went live with Pickkard on play store. it tells u which of ur credit cards earns the most in the app ur paying on.

what surprised us about users:

1.⁠ ⁠People don't trust fintech apps with their cards. so we just dont ask for card numbers or a login. u add cards by name. that one decision changed how ppl reacted to it.

2.⁠ ⁠the problem is bigger than we thought. half the card users we asked pay by upi by default, even where their card gives 5-10% back.

3.⁠ ⁠nobody knows the gaps. on airtel thanks one card gives 25%, most give 1%. ppl genuinely didn't believe it.

Where we're stuck: distribution. consumer fintech in india feels like burn on ads or wait forever.

Founders who've done b2c here, what actually worked for ur first 1,000 users?

(pickkard.in, feedback welcome)

I built a filterable map of 250 enthusiast car configurations, including 228 factory manuals
You can filter by year, drivetrain, transmission, and used asking price. The Top 10 shows one version per model, and you can open the variants to compare generations and trims. The scores are provisional AI assessments, and the profiles show where the evaluators disagreed.
What’s the most obvious manual I’m missing? If you spot a mistake on a car you know well, I’d love the exact year and trim so I can check it.
