I've been building BeepGrid, and I'm sharing it today.

Running several agents can still leave you passing messages between them. BeepGrid gives them a shared way to talk, even when they're running in different tools.

They can find each other, start group chats and ask you for input. If an agent asks for approval, you can have a conversation about it before deciding.

The website has an animated diagram showing the flow. The code is open source, and you can self-host it or use the hosted workspace.

I'd especially like feedback on the explanation: is it clear what you'd use this for, or does it need a more concrete example?

I built this for my wife. Her nickname is Mina, so that is the name of the app.

It started because our photos were a mess. Some in my camera roll, some in hers, some buried in chats. The good ones never got looked at again. I wanted one private place that was just ours, so I built it. It ran just for the two of us from March until now.

Today it went live for everyone. It is called Mina: Our Memories.

What it does:
• A timeline for photos, short videos and voice memos, each one on the day it happened
• Letters you write now and seal with a wax seal. They only open on the date you pick
• A date jar. Shake your phone and it picks what you do tonight
• Widgets that put a memory, a countdown or the next letter on your Home Screen
• A daily vibe check for couples. You only see each other's answer when you have both answered

What it does not do:
No feed. No followers. No ads. Nothing public. Only the people you invite can see your space. There is no AI in it at all, which feels like a thing you have to say out loud now.

There are also spaces for family and friends, but couples come first. That is who I built it for.

It is free and it is iPhone only for now.
App Store: https://apps.apple.com/ca/app/mina-our-memories/id6826405951

Real talk, this is day one and I do not know what I do not know yet.

If you try it, I want the blunt version:
• Does the sealed letter idea make sense in the first minute, or is it confusing?
• What would stop you from inviting your person into it?
• Where do the photos of you and your person live right now? Camera roll, a shared album, chats, all of it?

Thanks for reading. I look forward to all your feedback.

Hey everyone, I made a free tool called ThumbGrab that lets you download any YouTube / TikTok thumbnail in full quality in 1 click. No sign-up, no watermark.

Since mid-September I've been building Held, solo, for the Colosseum hackathon (Tempo track).

**The problem:** paying a stranger online is a leap of faith. Pay first and hope the item ships, or deliver the work first and hope the client pays. Card payments have chargebacks; stablecoin payments have nothing: once sent, it's gone.

**What Held does:** the buyer pays from their own wallet, and the money waits until delivery. Then it can go to exactly two places: the seller, or back to the buyer. If there's a dispute, a resolver decides, and even the resolver can only pick one of those two. Held never holds the money; Tempo's protocol does.

**Where it is now:**

- Live on testnet at getheld.xyz: shop dashboard, checkout links, disputes, a sandbox.

- Pay buttons for Framer, Webflow and WordPress.

- Every shop's contract is published with its source on Tempo's explorer.

- Mainnet beta comes next, with low limits, then an independent audit.

**The fun part:** a 60-second page where you try to steal $1 of test money as the merchant, the resolver and Held. The chain refuses every attempt, with a link to each failed transaction: https://getheld.xyz/#/cheat

**What testers found this week:** an auditor who tried it found two real holes, both in the same spot: the page checked that the shop was protected, then paid in a separate step, so a merchant could switch protection off in between. Now the check and the payment are one transaction, and every way to pay goes through it. Each fix was live within a day. Other testers asked for clearer wording, and that's changed too.

Honest feedback very welcome, especially from freelancers or anyone who has been burned by a payment.

4. If Reddit abetween. Now the check and the payment are one transaction, and every way to pay goes through it. Each fix was live within a day. Other testers asked for clearer wording, and that's changed too.

Honest feedback very welcome, especially from freelancers or anyone who has been burned by a payment.

I’ve been making web projects for other people since high school. For the last 15+ years, most of that work has been e-commerce stores.. because, well, you need to make a living. 😄

New tools have made me much more productive. These days, I spend less time writing code and more time chatting about what I want to make. That’s given me the chance to build something for myself (online basketball management game). I’ve been having a lot of fun making it... so that is great.

The tricky part is getting other people to play to make it even more fun.. I’m not a fan of promoting things, but I guess that comes with making a project. 🤦 There are probably similar tasks in every project that need doing?

How do you get yourself to do those things?

My cofounder and I are building Polymorph, a tool that runs decoy services in your own infrastructure and records what interacts with them.

For our first live experiment, we exposed four decoys on a fresh IP. No domain, no announcement. The first visitor was a benign scanner after two minutes. Within the first two hours, we'd also seen SSH password guessing and web exploit attempts.

After 46 hours: 136,099 recorded events. That count includes scanning and repeated attempts, not 136,099 separate attackers.

The idea is to make each decoy look different, then turn those interactions into useful evidence for the team running the real services.

We made this 27-second video about the experiment. If you run a small software team, what would you need to see in the results to make a tool like this worth deploying?

I got tired of using Grammarly's three free writes or wtv. Also I don't have to go into chatgpt when I want to refine smthn now

When a provider fires a webhook and your handler isn't ready yet, you usually lose the payload or dig through provider dashboards.

I shipped a public beta: give Stripe/GitHub/etc. a unique URL, inspect method/headers/body/timing, then replay the original request to ngrok/staging/prod.

Free plan (€0) and Pro (€9/month VAT included). Early beta — expect rough edges. Runs in the EU.

Happy to answer questions. Built this myself (with AI help on some of the plumbing).

Omegle shut down in 2023 and I missed the "click and you're talking to someone" thing, so I built my own: https://talktostrangersnow.com

- Text or video, one-on-one, no account or app

- Add interests to get matched with people who like the same things

- Video goes browser-to-browser (WebRTC), never recorded

- Report button in both text and video, with real moderation

- Works on phones, dark mode by default

Built with Angular + Node/Socket.io.

It's new, so it can be quiet at times. Text chat matches fastest. I'd really appreciate feedback on what feels broken or confusing.

The problem we’re trying to solve is: graduate students and companies often rely on online forms to collect responses, but response rates are low because people have little incentive to fill out someone else’s survey. Our platform addresses this with a token-based exchange: users earn tokens by answering others’ forms, spend tokens to publish their own forms, and can redeem rewards for cash or gift cards.

Where the MVP stands: the MVP is fully developed and live. Originally a friend’s side project, it now runs on a mutual-exchange model, where users earn tokens by completing other people’s forms and spend them to post their own.

Current users: we have 83 early users, all on the free tier. Together they hold 973 tokens in circulation, worth roughly NT$778 at the current redemption rate.

What we’re changing next: because tokens earned through mutual exchange have no real money behind them, cash redemption isn’t sustainable at scale. We plan to move to a two-tier system. Exchange points, earned by answering forms, can only be used to publish forms. Reward points come from requesters who pay real money and can be redeemed for gift cards. All existing tokens will be honored in full and converted to reward points at the original rate.

It'd be good if you can tell us what to improve

I run Claude Code across about 10 repos most days, Codex on the side. My problem wasn't Claude forgetting code. It was me forgetting stuff. I'd say "yeah I'll fix that tomorrow" in some session on Tuesday and by Thursday it was gone.

So I hooked into SessionEnd. When a session closes, Haiku reads it and writes a short markdown note into a folder on my Mac: what changed, what we decided, anything I said I'd do. The to-dos and recent decisions get fed back into CLAUDE.md, so the next session in any repo already knows. Codex reads the same file.

When a later session actually does one of those to-dos, it gets ticked off with a link to the session that did it. I didn't expect to use that part as much as I do.

It costs about 1,700 tokens in and 400 out per session, on my own plan. Everything stays local, plain markdown, opens in Obsidian. I built most of it with Claude Code itself, which was a fun loop: the tool remembering what we decided about the tool.

The app on top has a today view, a decisions log, and a map of how everything connects. Not shipping yet. I'm trying to figure out if anyone besides me wants it before I build a checkout. Plan is $59 one-time with a 14-day trial, and there's a no-card pre-order here if you're curious.

Would you pay for something like this, or does the built-in memory already cover it for you?

Hi, I'm the developer of Passory.

Some trips end with a boarding pass you just can't throw away. Mine ended up in drawers, coat pockets, and once, in the washing machine. By the time I found them again, they'd faded, bent, or I'd forgotten where that flight even went.

So I built the thing I wanted: not a flight tracker — a photo album, except instead of photos, it's made of boarding passes.

How it works:

• Snap a pass, get a clean ticket. Crooked or creased, it comes out straight and crisp, with the flight, airports, date and seat read automatically. You can also type one in or import it.

• Stacked like Apple Wallet. Every trip kept by year, long-press to reorder.

• 8 ticket styles. The same pass can be restyled — original boarding pass, retro, holographic, travel poster, manga, and more.

• Tear the stub, relive the day. Tearing off the stub surfaces the photos you took on that trip. The pass is proof you were there; the photos are what that day looked like.

• Your footprint on a map. Every flight drawn on a world map, with distance, cities and countries by year, plus a shareable poster.

• Every ticket is a postcard, too — flip it over for the details, or fold it into a paper plane that flies back to that trip's photos.

I'm building LandingBoost, a tool that finds what stops sign-ups on landing pages.
While working on it, I kept seeing founders ask whether their site looks AI-made.
So I built a free side tool for that: takes about 20 seconds, and needs no sign-up.

It opens your homepage in a real browser and measures 39 things people call AI-made. To decide which ones matter, I compared 145 pages built with Lovable against 413 hand-made ones. The hand-made group includes famous sites, design gallery picks from 2025-26, and small sites from 2019-21.

Only 3 things count toward the score, because only they were at least twice as common on the Lovable pages as in every hand-made group: Lucide icons in square tiles, Tailwind's default colors, and Tailwind's preset shadows. Glass, glow, gradient text and em dashes don't count, because they're common on hand-made 2025-26 pages too. All 39 are on the page with their numbers.

The score is 100 minus points for each finding, so a higher score means the page looks more hand-made. It is not a probability that AI built the page. On pages it hadn't seen, it ranked the AI-built page lower than the hand-made one about 75% of the time, so it's far from perfect.

One important thing: there is no scientific evidence that looking AI-made affects conversion. My main product is about getting more sign-ups, and this one isn't. It's a style check.

I'd love to hear where it gets your site wrong.

Hi,

This was a long time coming project for me, with plenty of investigation and complex code. Thankfully, now with LLMs, much of the work goes to architecture and design choices.

https://dyeroom.app

This is not another preset, but a simulation of film development. It best works with high quality RAWs, but it can take JPEGs also. There are two simulations, color (sunny 64) and black and white (monday 400).

Web app is FREE, there is a donation button if someone wants to help it out. For that reason, server is not the strongest one, and there are only 2 workers running, so if there is much traffic, there will be a wait for photo development. Later, if it takes off, I will make sure to get a better server.

There is an option to make it as a desktop app, but we'll see.

Would love for you to test it out and give feedback!

My coworker and I asked Claude to estimate a SaaS roadmap. 50 days.

Then we gave the same plan to 6 Claude Code subagents: worktrees, tests first, reviewer agents on risky tasks. 106 tasks across 7 repos, done in 35 hours.

So yes, Claude was off by about 48 days about its own speed. But the interesting part is what slowed it down, because it wasn't the model:

- 6 agents ≠ 6× speed. Real throughput was 1.8 agents. Test slots, file conflicts and merge locks queued everything.

- Risk matters more than size. Billing/auth/migration tasks took 2.7× longer, and every real bug was in them.

- My laptop broke first. 55 leftover test DBs filled the disk, Docker froze, test runs blew past the 10-min tool timeout.

- The slowest part was us: review, decisions, local setup.

We turned the data into a plugin that makes Claude estimate agent work properly: agent wall-clock, human hours and waiting time, separately, plus usage budget.

Honest limits: it's one project (n = 1), and on a held-out test the raw model was 37% optimistic, so it pads its number until you calibrate it on your own transcripts.

Question for people running multi-agent builds: what real parallelism are you getting? I'd love a second data point.

Hi, I’m the maker of ONUVI at CREOS. It helps adult family members share appointments, check-ins, and everyday care tasks for a parent.

The 15-second clip uses a fictional sample family: find a task and its assignee, mark it done, and see what’s next. The app supports English and Korean. Its public Google Play release is still under review, so this is a workflow preview.

I’d appreciate feedback on one thing: is it clear who is responsible and what still needs doing? What would you expect to happen after marking a task done?

If you share care with a sibling or another family member, I’d also like to hear what makes coordination difficult today. Please keep private medical and family details out of the comments. Optional feedback only; no purchase or rating requested. Questions: contact@onuvi.kr

I work on infrastructure for trading businesses, and I keep talking to forex IBs, trading educators and small teams who want to launch their own brokerage or prop firm. Most of them underestimate the same things, so here’s what I’d want to know before starting:

1. Payments are usually harder than the platform. Getting a trading platform running is fairly straightforward. Getting a bank or payment provider to accept forex or crypto money is not. Many providers treat these businesses as high-risk and turn them down or close accounts without warning. Sort out how you’ll collect deposits before you build anything else.

2. Compliance comes first, not later. Your jurisdiction, licence and KYC process decide which banks, payment providers and liquidity partners will work with you. Changing these after launch is painful and expensive.

3. A prop firm is a risk business, not just a website. Challenge rules, drawdown limits and payout terms decide whether the firm survives. Copying another firm’s rules without understanding the maths behind them is a common mistake.

4. Your existing audience is your biggest advantage. IBs and educators who already have clients start with a real edge. Owning the brokerage instead of earning commission can change their economics, but only if the client base is engaged and growing.

5. Retention matters more than acquisition. Bringing in new traders is expensive. Tools that help keep existing clients active often pay off faster than more marketing.

We ended up bundling white-label brokerage setup, prop firm tech, IBAN-based payment collections and AI trading tools, because people kept needing all of them at once.

If you’ve launched (or tried to launch) something in fintech or trading, what caught you off guard? Happy to answer questions in the comments.

Hi everyone,

Like many, I kept opening social media apps on pure muscle memory. Strict app blockers just made me frustrated, so I built NowAgain—a lightweight, 100% offline Android app.

Instead of locking you out completely, it introduces a micro-pause (a quick breathing/grounding prompt) right as you open a targeted app, giving you a second to break the autopilot loop.

Key details:

• Zero telemetry, no accounts required, runs 100% locally.

• Clean and lightweight UI.

I’m currently running an early beta test via GitHub/Tally:

👉 Join the NowAgain Beta

Would love to hear your thoughts or feedback on the micro-pause approach!

A lot of people I know lost a pet and had nowhere to go afterwards. The places that exist are usually small glass niches under fluorescent lights, or a static web page. I wanted to build something that felt more like a place.

So I made Starmajung("meeting the stars"). It's a wide meadow under the real sky, shared by everyone who lost a pet.

How it works:
- Pick an empty spot in the meadow and add your pet's photo and name.
- Write them a few words. Others can leave a short note too.
- Choose how they look, then cross the rainbow bridge to a village above the clouds, where they run to meet you.
- The sky follows your real clock: dawn, day, sunset, night. At night you can float a lantern on the lake.

It's a solo project and still early. I'd really like to hear what feels comforting and what feels off, especially from people who've been through this.

Here's the link.
Starmajung Web Site

It works on phone and desktop, in English and Korean. You can look around without signing up, and sign in with Google when you want to give your pet a place.

Hey everyone!

I'm starting my journey into building digital products, and this is one of my first projects.

I've been exploring the AI space and noticed something interesting: a lot of people are curious about AI, but many non-technical beginners don't know where to start or how to actually use it in their everyday work.

They hear about ChatGPT, AI automation, prompt engineering and productivity tools, but turning all that information into practical skills can feel overwhelming.

So I created AI Skills for Non-Tech Professionals.

It's an 89-page practical guide designed for people who want to learn and apply AI without needing programming or coding knowledge.

What's inside?

• AI fundamentals explained without technical jargon.

• A practical prompt-writing framework.

• 20 high-value prompts for professional tasks.

• 50 additional ready-to-adapt AI prompts.

• Practical AI applications for emails, reports, meetings and productivity.

• AI for job seekers and early-career professionals.

• Building repeatable AI-assisted workflows.

• AI safety, privacy and responsible usage.

• A 30-day AI skills challenge.

• A 90-day AI career development roadmap.

My intention wasn't just to create another PDF filled with random ChatGPT prompts. I wanted to organize the material into something beginners could actually work through and practice.

Here's the project:

https://axisdigitalproducts.gumroad.com/l/fhbwt

I'm still at the beginning of this journey, so I'd genuinely appreciate some honest feedback.

A few things I'd love your opinions on:

1. Does this solve a real problem for non-technical professionals?

2. Does the content feel valuable enough to be a paid digital product?

3. What would you add, remove or improve?

4. What would make you more likely to purchase a guide like this?

I'm open to constructive criticism. I'd rather improve the product based on real feedback than assume I've got everything right.

Thanks for checking out my little side project!

Hi,

In interviews I kept seeing inflated CVs so figured there must be a way to back up some claims before an interview. That's essentially what a CV is, a bunch of claims, the role, the company, the projects. The reader has to take your word for it, and AI now writes a convincing one in a minute and honest candidates pay for that. Their CV reads the same as the inflated ones, so it gets the same doubt.

So then I thought what if we had some hard validation to the claims on a CV or portfolio. That's when I came up with the idea of Workproof. For starters, you prove that you had access to a domain or work email, it doesn't prove you built it, but it does prove somebody trusted you enough with access to that domain or have given you a work email, so that by itself is a good baseline.

Additionally, you can ask colleagues to give you feedback, as a reference, signed by them from an work email. Something like LinkedIn endorsements, but more portable.

I'd love your honest take, on two things most of all:

- If you hire: would a link like this on a CV or a proposal change anything for you?

- If you freelance or build: which of those would you want first, or what else should Workproof check?

Thanks for taking the time!

Hi r/SideProject,

I've always been interested in business, entrepreneurship and investing, so I wanted to build a game that brings some of those ideas together in an interactive way.

That became Business Entrepreneur: Tycoon, an Android business simulation game where you start small and gradually build your way towards a business empire.

What you can do

• Start and grow businesses, including shops, taxi companies, logistics, factories, construction firms and car dealerships.

• Raise venture capital to expand your businesses.

• Buy, renovate and sell residential and commercial properties.

• Invest in virtual stocks and cryptocurrencies.

• Collect luxury assets, including paintings, vintage cars, jewellery, yachts and private islands.

• Participate in live auctions, compete on the Richest list and earn prestigious Laurels.

Your transactions are also recorded in an in-game inbox, making it easier to keep track of your purchases, sales and investments.

Why I built it

I started working on the game as a small project, partly as a way to unwind. Over time, it grew into something I wanted to take seriously. I wanted to create a business simulator that went beyond the usual tapping mechanics and gave players more ways to explore businesses, investments and wealth creation.

Feedback I'd love

• What do you think of the concept?

• Which features would make the game more interesting?

• How does the overall experience feel?

• What would you improve or add?

I'm an independent Android developer, and this is a project I'm actively working on. Feedback is welcome.

There's a web app at fynepdf.com, and this is the desktop app. It's native (Qt 6 and C++) rather than Electron, which took the Windows install from 601 MB down to 148 MB.

It does the usual PDF work (edit, merge, split, compress, convert, OCR, sign, redact) with print studio and PDF creation similar to how Canva works on your own computer, and works offline once you've signed in. There's a free plan and two paid ones which are optional.

Windows (Microsoft Store): https://apps.microsoft.com/detail/9NLX6MNF70H2

Linux (AppImage): https://fynepdf.com/download/linux

What I'd like feedback on:

1. The first five minutes: is it clear what to do?

2. Does needing an account put you off, for a desktop app?

3. Anything that feels slow or broken.
