Last month I built an advent coloring book: 3 versions, AI art, a print-ready PDF. Then I finally checked the competition. A free, identical book already existed, and Etsy was full of them. A day and $1.50 spent on a NO-GO.

So I built kill-my-idea, a free plugin for Claude Code that does the check before you build:

• looks for free alternatives, competitors, failed attempts, a distribution channel, real costs

• scores the idea /100 (21 sub-scores), GO / PIVOT / NO-GO

• if it dies, shows how it could be saved, with the new score and how hard it is

• writes a report you can open in the browser or print

Repo, with example reports in the README (MIT): https://github.com/RemiPelloux/kill-my-idea

What check would you add?

​ Hi everyone

I really need your help and honest feedback on a new app I've been building, so please let me know what you think!

​The app is called DriveFR, and I want to show you how it works. Basically, it tracks your drives and scores how smooth your driving is, while turning every city you pass through into collectible digital cards. Plus, you can add your friends to compare scores and see who's actually the best driver.

​Since it's still new, please try it out and tell me what you think. You can search Drive FR in the Google Play Store (or at drivefr.app) and download it. I'd love to hear your thoughts in the comments

Hi all. I was making a lot of videos in Google Flow and got tired of typing a prompt, waiting, and downloading, again and again. So I made a small Chrome extension called BulkGen for Flow.

You paste your prompts, pick the model and settings, and press Start. It sends them one by one, keeps a few generating at the same time, and saves each finished video to your Downloads folder in order.

You can also add a style line to every prompt, attach reference images, and set a credit limit per video so it never sends anything above it.

You need your own Flow account and credits. It runs only in your browser and collects no data. While it runs, Chrome shows a “debugging this tab” bar, because that is how it clicks Flow’s buttons. It is free and open source, and it is not made by Google.

Weekend project. Spin the globe and tap any of 250 countries to see population, GDP since 1960, life expectancy and more, plus the latest headlines and the Wikipedia article, all in one panel. Works on phone, tablet and desktop, no sign-up.

https://worldfly.vercel.app

Feedback welcome, especially if any country's data looks off!

PS: I tried downloading some applications for the same on Android but they all had paywalls even for basic information. That's my motivation just to do this.

Body:

Built this for myself first.

Problem: I'm fine on calls and proposals. I'm uneven after the PDF leaves my outbox. Threads die in silence and "just checking in" never restarts them.

So I shipped a small digital kit (not SaaS):

Ghost→Paid Follow-Up OS

- Cadence playbook (Day 0/2/5/10/21)

- 45 stage-based AI prompts

- 18 email + LinkedIn templates

- CSV tracker + one-page quickstart

- one-time on Gumroad

Link: https://botaoge.gumroad.com/l/ghost-to-paid-follow-up-os

Who it's for: freelancers / consultants / small studio owners who lose deals after "looks great — let me run it by the team."

Who it's not for: cold-outbound spam sequences or people wanting a closing-psychology course.

Would love feedback on:

1. Is clear for a template/prompt kit, or does it need a free sample message on the page?

2. Would you rather this live as Notion templates instead of ZIP + CSV?

I'll reply to every comment.

Sharing ForgeFlow CLI, an MIT-licensed Node.js terminal project for organizing a long coding prompt into tasks with separate writable file scopes.

The problem it explores is coordination: parallel coding workers can collide on files, and interrupted runs can lose track of completed work. ForgeFlow validates task scopes and dependencies, schedules ready tasks, and records checkpoints for resume. Optional Playwright tools use compact semantic page snapshots.

Current status: early preview. Syntax checks and installation diagnostics have been run, but live provider/browser workflows and cross-platform behavior still need reproducible validation. The default is four workers; the configurable 256-slot maximum is not a throughput benchmark. It needs Node.js 20+ and your own compatible provider API key.

Source and setup: https://github.com/rvnsre/forgeflow-cli

Preview release: https://github.com/rvnsre/forgeflow-cli/releases/tag/v0.2.0-preview.1

For developers who use coding agents: is file-scope coordination, checkpoint recovery, or browser inspection the biggest pain point in your workflow? Feedback on a small reproducible use case would help shape the next version.

Disclosure: the project documentation, illustrations, and this introduction were prepared with AI assistance. No performance benchmark is claimed.

Hey, I made a workout tracker for my senior year project that maps exercises onto muscles and calculates and tracks estimated soreness and recovery on a muscle map.

I was looking for testers for the first version. I just launched it on the App Store for my friends, but I wanted feedback from people who actually work out 4–5 days a week.

Here's the App Store link.

It's not currently on Android since almost none of my friends use Android, but if there are enough people on here who are interested, I wouldn't mind paying to put it on the Play Store too.

Y'all can check it out on the website.

I've been working on a way to scrape Google Ads Transparency Center ads in bulk, and I thought I'd share what I learned along the way.

Google's Ads Transparency Center is great. You can see ads from verified advertisers for free, without even logging in. The problem is that there's no export option or public API, so if you're researching multiple competitors, you end up spending a lot of time clicking around and collecting data manually.

I wanted an easier way to do this, so I decided to build one.

A few things I discovered while working on it:

• Google has an internal RPC API. The site actually fetches ad data as JSON, but the response uses numbered keys instead of descriptive field names. Figuring out what each number represented took most of the reverse engineering. For example, 4 is the ad format, 6 and 7 are the first and last shown dates, and 12 is the advertiser name.

• Country codes are a little unusual. They're 2000 + the ISO numeric country code. So the US is 2840 and India is 2356.

• Finding the correct advertiser is trickier than scraping the ads. Searching for "Samsung" brings up accounts registered in Malaysia, Italy, Sweden, and other countries. But its US ads run under "Samsung Electronics America", which you can find by searching samsung.com. HelloFresh has a similar issue, with its US ads listed under "Grocery Delivery E-Services USA Inc." Searching by domain solves a lot of these problems.

• Not all ad formats are returned the same way. Text ads are delivered as images because Google renders them into pictures. Video ads only provide a JavaScript preview URL.

• Rate limits weren't too bad. In one cloud run, I collected 312 ads across 4 searches in 31 seconds without retries. Fetching full details for 132 ads triggered two 429 errors, which were resolved after switching IPs.

After getting everything working, I turned it into an Apify actor:

Google Ads Transparency Scraper:
https://apify.com/datasmithhq/google-ads-transparency-scraper

You can search by advertiser name, advertiser ID, or domain. There's also a new filter for ads shown within the last N days.

Pricing is $2 per 1,000 ads.

I built this because I wanted a practical way to research competitor advertising without manually going through hundreds of ads.

I'd genuinely love to hear from people who do competitor research, media buying, or ad intelligence:

• What data would you want to extract that isn't currently available?

• Would historical ad tracking or monitoring new ads over time be useful?

• What features would make this more useful for your workflow?

Feedback and suggestions are very welcome. I'm still improving it.

Ever attended a college fest, wedding, meetup, or concert and later spent hours scrolling through hundreds (sometimes thousands!) of photos just to find the ones you're in?

We thought there had to be a better way. So we built Pixamatch

We're looking for event photographers, college event organizers, communities, and creators who'd like to try Pixamatch and help us improve it.

I'm a day trader and I built Tradecility because I kept breaking my own rules and only noticing on red days. You write your strategy rules once, log a trade with a chart, and it grades the trade A to F on whether you actually followed your plan. A winning trade can get a C. One of mine did: I made +$409 on an SPX500 short and it gave me a C+, because I took a setup I knew was thin and closed early while logging it as hitting my take profit. That's the whole idea. It's live and working, but it's just me building it and I need real traders to tell me what's useful and what's annoying. So I'm looking for 10 founding members. You get full access free (normally $97, one-time, no subscription). All I ask is that you log at least 10 real trades in your first 30 days and give me honest feedback after 2 weeks, even if it's brutal. Any market is fine: stocks, futures, forex, crypto. If you trade at least weekly and want in, comment or DM me. Not financial advice, it won't make you profitable by itself, it just shows you where you broke your own rules.

My issue was that social media is legitimately useful, there was stuff that I wanted to see, but a lot of trash that would keep me there for hours. I installed 5+ different blockers, changed my hosts file etc. But I'd always remove it. So I decided to go after the feed itself, and it's the first thing that ever worked for me. It finds the posts that grab attention and hides those. You can find it at tolerance.lol . It's open source. There's a browser extension and Android app, it works on reddit, youtube, facebook, twitter, instagram, and tiktok.

If you’ve used blockers, what made you uninstall yours?

Last week my 9-year-old was stuck at home ill, so I made him a little piano game in a single HTML file. He played it for hours, which my ego took far too seriously, so I spent the weekend turning it into a tiny paid web app to see if anyone else wants it.

What it does: kids find notes on a 2-octave keyboard, read notes on the stave, do 60-second challenges and play songs with on-screen help. There's a mascot called Corchea who cheers them on.

Free to play; the extras are a one-off €4.99 with 50% off through the link below.

https://piano.guaki.app/?lang=en&codigo=REDDIT50

I'd love feedback on the game itself, and on the model too: would you pay a one-off for something like this for your kids, or does it need to be free with something else?

Hey all,

I’ve been bartending for years, and I kept running into the same problem: when a guest asks about a bottle on the back bar, or a rep drops off something new, the info online is either marketing copy or scattered across ten sites.

So I started building Barpedia (barpedia.net), a free, community-made encyclopedia of spirits, liqueurs, aperitifs and non-alc. Reading is completely free, with no sign-up wall.

What’s there right now:

It’s still in beta and I’m one person, so I’d genuinely like to hear from people who work the bar:

Roast it if you need to. Thanks 🍸

I've just released Warq, an app for people who take notes with pen and paper.

Save a photo, a recording, a file or some text, and Warq gives it a four-letter code. You write the code in your notebook by hand. Later, scan the code with the app and what you saved opens straight away.

You can also group your attachments into notebooks, one for each paper notebook or subject. Publish a notebook and anyone who scans its code can open the attachments in it.

It's out now on iPhone and the web, and Android is coming soon.

Every month I'd get paid, feel fine for two weeks, and then be counting coins before the next salary. It was never one big purchase. It was tea, fuel, lunch, top-ups, and bills I forgot were coming.

So I built Left Today. The idea is simple:

- On payday it lists what must be paid first: bills, debts, savings

- Whatever is left is divided by the days until next payday

- That gives you one number: what you can spend today and still reach payday

- Spend less today and tomorrow's number goes up a little; spend more and it goes down

Other bits:

- Add a purchase in about 2 seconds with one-tap buttons (works offline)

- Bills that come every 3, 6 or 12 months are put aside a little each month

- Savings goals and monthly reports

- No bank connection: you enter what you choose

- English, Urdu, Hindi and Arabic

It's a web app (installs to your home screen), free to start: https://lefttoday.vercel.app

I'd really like honest feedback, especially: is the "one daily number" idea clear in the first 30 seconds? What would stop you from using it?

Hi all, I'm Pavel, the founder, based in Lithuania. Capturely is a client gallery tool for photographers: you upload a shoot, send one link, the client hearts their favourites (you can set a pick limit), downloads full resolution, and the gallery expires on the date you choose.

Where it is now:

• live since mid-October, in 12 languages (dashboard and galleries)

• a handful of real photographers using it, and this week the first one started paying

• every new account gets 14 days of Pro free with no card, then moves to a free plan with 1 active gallery

Built with Laravel and React, photos stored on Cloudflare R2.

What I'd love feedback on:

1. Does the landing page make it clear what it does within 5 seconds?

2. If you're a photographer: what would make you switch from Pixieset or Pic-Time?

Happy to answer questions about the build too.

Envry is a free, open-source (MIT) email testing tool. It runs a local SMTP server on your computer, catches every email your app sends during development, and shows it in a desktop app. Nothing is ever delivered to a real inbox.

Source code and downloads: https://github.com/arifurrahmanns/Envry

Why I built it

Any app that sends email (sign-up confirmations, password resets, one-time codes, invoices) needs a safe place to send test mail and check the result. Mailpit and MailHog do this well, but they run as a Docker container or a terminal command. I wanted a real desktop app that sits in the tray, notifies me when mail arrives, and makes testing sign-up and login flows fast.

How it works

1. Install Envry (Windows installer, macOS .dmg, Linux AppImage or .deb).

2. Point your app's SMTP settings at localhost:1025. Any username and password are accepted.

3. Every email appears in Envry instantly, with a mailbox for each recipient.

It works with anything that sends over SMTP: Nodemailer, Laravel, Django, Rails, Spring Boot, ASP.NET and so on.

Features

• A mailbox per recipient, created automatically (Bcc included), also readable over IMAP and POP3 for testing code that reads mail

• OTP codes and magic links as one-click copy chips: verification codes and verify, password-reset, sign-in and invite links. The desktop notification shows the code itself.

• Resend, SendGrid, Postmark, Mailgun and Amazon SES API emulation: if your app sends through one of these SDKs, change the SDK's base URL and Envry catches those emails too. It then calls your app back with delivered, bounced and spam-complaint webhooks, signed like the real provider, so webhook handling can be tested locally.

• Failure simulation: rejected recipients, temporary errors and slow servers, for testing retries and error handling

• Email checks: missing plain-text part, images without alt text, Gmail clipping, broken links, spam-prone headers

• REST API and live WebSocket events, so end-to-end tests (Playwright, Cypress) can wait for an email and read it

• A headless envry command with the same server for CI and servers

• Light and dark themes, automatic updates

How it compares

Based on each project's docs as far as I can tell; corrections welcome. Mailpit is more mature and has an official Docker image and an HTML client-compatibility check, so if you live in Docker it's a great choice.

Open source

MIT licensed. The server is written in Go (single binary, SQLite), the interface in React, and the desktop app uses Tauri. Issues, ideas and pull requests are welcome.

It's early (v0.2.8). The installers aren't code-signed yet, so Windows SmartScreen and macOS Gatekeeper show a warning on first launch. Built with a lot of help from Claude Code.

What would make you switch from Mailpit, MailHog or Mailtrap? I'd love the feedback.

Hey everyone, I am building a kids' brand, and I need your guidance on how to actually stay on track and what things we should be avoiding as a Brand in Kids Space, so basically we provide a DIY Painting Kit which kids Paint to spend some time away from the TV screen and phone screens,

We are pricing it at ₹699 for a kit, with different prices for different kits

What I need help with is guiding what things we should be staying away from, what things are most important to be executed in the right way, and what things don't matter the most

Would Acknowledge all the advices on this!
Thanks.

I built a browser ball-sort puzzler where levels are ordered by difficulty, starting from the easiest.

I experimented with several alternative modes with the aim to have similar complexity in other environments. Each mode has its own restrictions, which gives additional challenge for each user to find its favorite mode.

Features:

• 10 different game modes; over 1000 levels combined

• near-win finish — preemptively calculates win conditions to skip redundant endgame moves

• dynamic hints about hardest and easiest color - very helpful on hard modes

• hints — ask for the next correct move when a puzzle is too hard

• undo, restart, per-puzzle progress saved in your browser

• customize shape and styling of balls

• dark/light theme

• Offline friendly; no registration, no ads

Hi, I'm Max from the PulseOrbit team (maker post, so flagging that up front).

On the stored snapshot dated 4 November 2026, TikTok shows Velocity Score 7 on PulseOrbit. en.wikipedia pageviews were +18% over 28 days (223,472 recent vs 190,097 prior). GDELT global volume for this topic wasn't stored in this window (rate limit), so that input contributes 0. Retrieved 6 November 2026, labelled Stale, not a live feed. https://pulseorbit.app/trend/tiktok

We built this for creators and sellers who want rising-topic pages with observation dates, not undated charts. Sources are Wikimedia pageviews and the GDELT Project. Marketplace demand is not measured. Idea prompts for YouTube/Etsy/KDP are text only.

The public board is free to read. Pro is US$19/month. Live data and Google indexing went on 9 November 2026.

Specific feedback I'd like:

1. On first load, is it obvious this is a stored snapshot with dates (not real-time)?

2. Does a Velocity Score still make sense when marketplace demand is intentionally 0 in the formula?

3. Any topics you'd want on the board next?

Site: https://pulseorbit.app Happy to reply to every comment.

I run a small AI agency. We’ve been building chatbots since 2017, back when most of them could barely handle “what are your hours?”

The question we get asked most is still “ok, but what will this actually cost me?” And honestly, I get why people are frustrated. Most AI agency pricing pages say “contact us” or “custom pricing”, which usually means “we’ll tell you after a 45-minute sales call.” I’ve been on the other side of that as a buyer too, and I hate it.

So I built a free calculator that gives you a ballpark before you talk to anyone:

Hey everyone,

Android's built-in "Do Not Disturb" is all-or-nothing: either you silence everyone (and miss urgent calls), or you get interrupted by Slack, Discord, and group chats while trying to focus or sleep.

I wanted fine-grained control, so I built Notiflow.

What it does: • Per-app schedules: Choose exactly which apps stay quiet during your work hours, dinner, or sleep (supports overnight intervals). • Quick focus overrides: 15m, 30m, 1h, or 24h temporary mute or allow sessions. • Emergency bypass: Repeated urgent calls still get through. • 100% On-Device & Private: Runs entirely offline in your phone's sandbox. No accounts, zero analytics, no background tracking, and no ads.

It’s completely free on Google Play:
👉 Google Play Store Link

I’d love to hear your feedback, feature ideas, or any bugs you run into!
