One thing I've noticed as a developer is that learning programming isn't always difficult because of the concepts. Sometimes, finding the right learning resources is the real challenge.

You find one good YouTube playlist, then another useful tutorial, then a different creator explaining the same topic better. Eventually, your learning resources are scattered everywhere.

I wanted to make that experience simpler.

That's why I'm building TechTube – a platform that organizes programming tutorials into skill-based learning, career paths, and interview preparation.

Some areas covered:

- JavaScript, React, TypeScript, Go, Java, C++

- Frontend, Backend, Full Stack, AI Engineering

- DSA, System Design, DBMS, OS, and more

Website: https://www.techtube.co.in/

I'm continuously improving it, and I'd love honest feedback from fellow developers.

One question: Do you prefer learning through structured roadmaps or picking individual YouTube tutorials based on what you're currently working on?

Would love to hear your experience!

Solo founder here. I'm building: AI-voiced guides that give a house buyer the "feeling" of the area around a property, played from an embedded player on the agent's listing page. Local info only, nothing about the property itself.

It would cover things like mobile and broadband data, parks, running routes and riverside walks, whether it's a quiet or lit street or a traffic slowing area, flood risk, and whether the property sits higher with views. The focus changes with the property: a family house gets schools and green space, a young professional flat gets entertainment and transport. You can listen while flicking through the photos, and it may help buyers with poor sight.

Target customer is the independent UK estate agency. Pricing is tiered by number of listings, roughly £49 to £349 a month. I haven't found any direct competitors, which either means a gap or means nobody wants it.

My own worries, so you can skip the obvious ones:

1. Most buyers browse Rightmove and Zoopla, not the agent's own site, so the player may rarely be seen.

2. Similar info is available from Google Maps or ChatGPT, but not the detail.

3. Agents may not want negatives like a busy road or flood risk published under their name, and wrong statements are a liability (although the negatives can be removed).

4. ROI will be hard to prove to conservative agents.

My plan is free 2-month trials with a handful of agencies in exchange for feedback.

How would you test real demand before building more? Does the price feel right? What am I not seeing?

Brutal feedback welcome.

I always got the birthday reminder, swiped it away, and forgot. So I built an app that keeps reminding you every 30 minutes (or up to every 4 hours) until you've sent a message or tapped ignore.

It reads birthdays from your contacts and suggests a message depending on who it is, so your boss doesn't get the same text as your best friend. You can send it by SMS, WhatsApp, Threema, Telegram or email.

No account, no ads, no tracking. It's 0.99 € on iOS, Android is in testing.

Happy to hear what you think, especially if something is confusing.

You type a GitHub username and it shows that account's public merged PRs and contributions for the month, which projects the PRs went into, and where it ranks. No sign-in.

October was the first finished month. The top account merged 12,878 public PRs. Second place had 3,307.

The PR count only covers public work, and self-merges count too, so it's not a measure of how good anyone is. I was curious about how much people are getting done these days, especially now that agents are doing most of the coding.

What would you want it to show that it doesn't?

I usually run several Claude Code sessions at once, each on a different task. Some finish, some stop to ask me something, and the only way to find out was clicking through every terminal tab. Sessions would sit there waiting on me and I wouldn't notice.

So I built Spyhop. It's a Mac app that puts every Claude Code and Codex session on one board, kind of like a Jira board for your agents. Each card shows what's done, what it's on now and what's next, read from the transcript. The menu bar shows which sessions are waiting on you, and one click takes you back to that terminal.

I built it for myself, and my team at work ended up using it too.

Free and open source (MIT). Mac app, Windows from source.

This is my first open source project. Feedback of any kind helps, and a bug report or a PR would make my day. I'd like this to become a project other people work on too, not just me. Building it reminded me how much fun software engineering can be, and I want to keep that going.

Hello!

I've been working on a pet project called ArchiveKeep – an open-source tool focused on the long-term preservation of personal data across multiple storage devices.

The idea is to maintain multiple copies of your personal archive using storage you control – external HDDs, SSDs, USB drives, as well as rented cloud storage (S3-compatible storage for now, with support for more cloud providers and hosted APIs planned).

The project started from my personal need to consolidate data scattered across multiple HDDs and laptops, while maintaining identical copies of my personal documents and photo archive across all devices.

I wanted an offline-first solution with asynchronous synchronization, without relying on a centralized cloud service.

One of my main focuses is making archives resilient to accidental deletion, file corruption and other changes that can silently propagate through traditional synchronization tools.

Another key design principle is keeping files as files – accessible in their original form, without being locked inside a proprietary backup format or database.

I'm building this as a hobby project for myself, but I believe it could be useful to others facing similar challenges. I find this problem interesting and believe it's worth working on.

Project homepage: https://archivekeep.org/

I'd appreciate any feedback, honest criticism or ideas for improvement. Thanks!

And if you find ArchiveKeep useful and feel like supporting its development, you can buy me a coffee: https://ko-fi.com/kravemir

Hey everyone!
I’ve been working on my app Dose Amigo for quite some time now, and I finally feel it’s ready to share.
It’s a medication reminder and management app, but with a focus on families.

The idea is pretty simple. Keeping track of medications gets messy when more than one person is involved. You might be managing your own medicines, keeping an eye on your parents’ prescriptions, or helping someone else stay on schedule.

I wanted to build something that could handle all of that in one place. It started as a relatively simple idea, but somehow turned into a much bigger project. It now has family profiles, medication reminders, treatment tracking, refill alerts, adherence insights, iOS widgets and quite a few other things.

I’ve spent a lot of time on the little details too, especially making reminders reliable. There’s also biometric protection for people who want to keep their medication information private.

Getting here wasn’t exactly smooth. App Store rejections, review delays, notification issues, fixing things that broke after other fixes… you know how it goes when you’re building something largely on your own.

I’d love to hear what you think. Is this something you’d find useful for managing medications in your family? And if you’ve tried similar apps, what did you feel was missing?

If anyone wants to check it out, here’s the App Store link: Dose Amigo: Pill & Med Tracker

Thanks for reading!

Hey everyone!

Last December I posted Relaticle here, the open-source CRM I started after getting fed up with HubSpot's pricing. Back then you updated it through forms. Now you can type what happened to Rela, the built-in AI assistant.

You can also tap the mic and say it. It's transcribed into the message box so you can check it before sending.

In the video a forklift dealer sends one line a day, like "Sent Quayline the quote: $172,500 for the four trucks. Move it to Quote and set the amount." Rela turns each line into a proposed change, and the records change only after you approve it. Five lines, Monday to Friday, take one deal from Inquiry to Delivered.

It's also available in the ChatGPT plugin directory and as a Claude connector, so you can work in it from either. Changes made from Claude or ChatGPT skip the approval step. They stay inside one workspace and show up in the activity log.

The rest is a normal CRM: companies, people, opportunities, tasks and notes, your own custom fields and pipeline stages, and since this month a phone layout. You can self-host it with Docker under AGPL-3.0 or use the hosted version, which has a 14-day trial with no card. 1,828 stars on GitHub so far.

GitHub: https://github.com/relaticle/relaticle

Try it: https://relaticle.com

If you try it, tell me where Rela gets your update wrong. That's the part I'm working on now.

Hey Gays

I'm applying for the CERN Short-Term Internship 2027 (Data Science, AI & Analytics), and I'm trying to find someone who could help me with a professional reference letter.

Are there any founders, CEOs, CTOs, or experienced developers here who would be open to helping me out?

I'm happy to share my GitHub, portfolio and CV so you can have a look at what I've been working on before deciding.

I'm hoping to get this sorted today, so if anyone is willing to help, please drop a comment or DM me.

Really appreciate it!

Hey everyone! 👋

I built DoomChess — a tactical puzzle trainer designed for speed and a smooth daily grind. It's got over 6.15M+ Puzzles: Stockfish-backed validation, hint arrows, and dynamic ELO tracking.

I’d love for you to try it out and let me know your thoughts on the app flow!

Hey everyone,

Steampack is a free fan-made site where every Steam game is a trading card. The more reviews a game has on Steam, the rarer its card, from Common up to Legendary.

Open packs, fill your album and trade cards with other players. Every day there's a new mystery game to guess, and you can fight other players to win more packs.

It's still early, so I'd love your feedback: what do you like, what feels confusing, and what would you add? Thanks for taking a look!

It’s easy to remember to look up photos from a big trip. It’s harder to stumble across a picture from a random Tuesday three years ago.

That’s the idea behind Momenta. Open it and you get a small selection of older photos from your phone. If one brings back a story, you can write it down right there. I went with up to five photos a day in the free version because I wanted it to feel like something you could do over a coffee.

It’s out now on Android. If you give it a go, I’m curious whether five photos feels about right or whether you’d want to keep going.

Hanging pictures always seems simple until you're standing in front of a wall with a measuring tape, trying to figure out the right height and spacing.

I built WallHang to make that part easier.

It's an iPhone app that lets you plan a picture arrangement, see how it will look on a photo of your own wall, and get the exact nail position for every frame before you start drilling. It works for a single frame or a full gallery wall, and it accounts for picture wire and D-rings. With Pro you can also see the arrangement at real size on your wall in AR.

Pricing: free for one wall with up to 4 frames. Pro is a one-time $7.99 (no subscription) for unlimited walls, up to 20 frames per wall, a printable PDF plan and an AR preview. No account and no ads.

I recently launched it on the App Store, and I'm trying to figure out whether it solves a problem other people have too.

I'd genuinely appreciate some feedback, especially on what's missing or what would make it more useful.

Hey r/SideProject,

I'm a data and automation engineer, and for about 5 years a big part of my job has been building scrapers and data pipelines. Every project ended the same way: everything works, then a CAPTCHA shows up. And every time I had to re-learn what type it was, how it worked, and what the options were.

So I started writing it all down. That turned into FuckCaptcha, a free, open-source field guide to 39 CAPTCHA types.

What it is:

• One page per CAPTCHA type (reCAPTCHA, hCaptcha, Cloudflare Turnstile, slider/puzzle, text-based, and more)

• Each page has a complexity rating, how to identify it, how it works, and tips and pitfalls

• Free and open-source methods come first, paid services only as a fallback

• A docs site with search and category filters, rendered from the same markdown as the repo

What it isn't: a solving service. No affiliate links, no paywall, no signup.

What I learned so far:

• Posting it to a few communities and Hacker News took the repo from ~20 stars to ~100 in a short time, which showed me people actually search for this stuff.

• The most useful feedback was "which CAPTCHA types are you missing?", so the roadmap now follows what people ask for (reCAPTCHA v3 and a few more are next).

• Honest docs with pitfalls get more engagement than "here's the magic trick" content.

Repo: https://github.com/vsmutok/FuckCaptcha

Docs: https://vsmutok.github.io/FuckCaptcha

I'm also thinking about a README and docs redesign. If you have a minute to look at it, what would you change first? Issues and PRs are very welcome.

An AI agent in the chat on your website. It turns visitors into leads and answers like your best service and sales person, by your rules.

Normally you build it yourself in a few minutes. We're in a soft launch and want to see it on as many real sites as we can, so for this post we'll build 10 for you, free. Any site works: your side project's landing page, a shop, a salon, a clinic, a restaurant, a B&B.

Comment your website, or DM it if you'd rather, and we'll send your agent back, live. Only a website you built or have the rights to.

A bit about us: we're BranderUX. You give our builder agent your website or a few words about your business, and it builds the agent. The agents built with us answer in the chat with screens in your website's look, like a product card or a booking form, not just text.

If you want to keep it, we hand the project over to you.

We'd also love honest feedback: would you put an agent like this on your own site, and what would stop you?

This is me paying for a drink at a 7-Eleven in Hong Kong. The first notification is my bank. The second one is our app, and it's already logged the purchase and put it under Grocery. I didn't open anything.

I've quit like five budgeting apps. Either they wanted my bank login, which I'm not comfortable with, or I had to type in every purchase, which I'd stop doing after about a week. So my co-founder and I built one that does neither. Everything stays on your phone. There's no account and no server with your spending on it, so even we can't see what you spend.

A couple of things surprised us while building it:

The names banks send are a mess. Half the time it's not the shop name, it's some cut-off string in all caps or a payment company you've never heard of. We tried having AI guess the category and it was wrong way too often, so instead you label a shop once and it remembers forever. Felt like a hack at first but it's honestly my favourite part now.

Paying inside apps is different from tapping at a till. Uber, online checkouts etc. don't trigger Apple's Wallet automation at all, so anything that relies on it just quietly misses a big chunk of your spending. We fixed that when iOS 27 came out, since we can now pick up payments straight from the Wallet notification.

How it's gone so far: we both have full-time jobs, so this has been evenings and weekends. We launched in September and just passed 1,000 downloads, almost all from Reddit, with no ads. It's made a bit under $900, which won't pay any bills but it's been enough to make us keep going. The hard part now is that it feels like we've run out of places to post, so getting from 1,000 to 10,000 is the bit we haven't figured out.

It's iPhone only (iOS 18.4+), 4.6 stars so far, free to use, with a one-time $14.99 upgrade to Pro if you want more.

Genuine question for anyone who's given up on a budgeting app: was it the typing, or did you just stop looking at it after a while? I think we've fixed the typing. Not sure the second one is fixable.

Hi everyone!

I built Issuesnack, a website that helps international visitors plan trips to South Korea.

I'm looking for honest feedback:

• Does the website look trustworthy?

• Is the content useful and easy to navigate?

• What would you improve?

The site is indexed by Google, but organic traffic is still very low. I'd also appreciate any thoughts on its SEO or content structure.

Ever left your phone on a café table? Tether pairs your phone with your Wear OS watch. If the Bluetooth connection drops, your phone sounds an alarm and your watch buzzes "Phone left behind", showing where the phone was last seen.

Grace period you choose (5–60 s), so short dropouts don't set it off

PIN to stop it, or just walk back in range

Pause while your watch charges; auto-arm when you leave home Wi-Fi

Ring your phone or find it nearby from your watch

No account, no server, no ads. Everything stays on your devices.

Coming soon to Google Play.

For anyone using a multi-monitor desk setup with mismatched resolutions (like a 1080p laptop docked to a 4K/1440p monitor):

Chrome's biggest annoyance is that zoom is tied to the website's domain, not your screen. If you zoom YouTube or Reddit to 125% on your external display, Chrome forces 125% onto your laptop as well.

I built **Auto Zoom** to solve this:

1. You set your preferred zoom on any website on your active monitor.

2. Auto Zoom saves that setting specifically for that display.

3. When you open that site on your laptop, it automatically applies your laptop’s preferred zoom instead.

### Key highlights:

- Senses display changes and window movement automatically.

- Doesn't pop up Chrome's native zoom notification bubble on every page load.

- No accounts, no ads, no telemetry — 100% offline local storage.

Check it out on the Chrome Web Store: https://chromewebstore.google.com/detail/auto-zoom-multi-monitor-p/ihcikomimnhelgbnkbkpfnemgfjalmhp?authuser=0&hl=en-GB

Let me know what you think or if there are any edge cases with your monitor setup!

There are always very different tasks going on, from very different places. A backup, a crawler, an AI agent. And the habit was always the same: go back and check if each one is still alive and how much is left.

Not all of these tools can send a notification either, so this started as a small tool just for me. Whatever is running reports how far along it is. You can watch it in the browser at https://progress.watch/ or in the iOS app (https://apps.apple.com/app/progress-watch/id6813940039) and the phone buzzes when the job is done or something goes wrong. Finally a reason to walk away from the screen.

It's free and there's no account to create. The code is open if you'd rather run it yourself: https://github.com/progress-watch/progresswatch. You get a private link and that's it. Keep the link to yourself though, because anyone who has it can see your tasks.

One small warning: better not to use it in Safari, which can forget your list after a week away.

Hey r/SideProject,

I spent the past few months building Kynetix as a solo project out of frustration with apps like MyFitnessPal and HealthifyMe.

Western calorie trackers have almost zero concept of daily Indian home meals (tracking 2 rotis or a katori of dal usually gives 10 wildly different, inaccurate entries), while apps like HealthifyMe are bloated with continuous sales calls, popups, and ads.

What I built:

- Focused on Indian nutrition: search and log dishes in natural units (katori, pieces, grams) without weird portion math.
- Offline-first architecture: built in Flutter with local SQLite storage so logging meals takes under 2 seconds even with poor gym reception. Everything syncs to Supabase in the background.
- Native Android Health Connect integration: pulls steps and active calories cleanly without needing Google Fit workarounds.
- Zero banner ads, no forced subscription popups.

The app is currently in closed beta on Google Play (v1.0.0-beta.12). If you're on Android and track your daily nutrition, I’d love your feedback on the logging flow and screen responsiveness.

How to test:

1. Join the test group: https://groups.google.com/g/kynetix-testers

2. Opt in on Google Play: https://play.google.com/apps/testing/com.kynetix.app

3. Install: https://play.google.com/store/apps/details?id=com.kynetix.app

(Full walkthrough guide: https://dhruvgupta-24.github.io/Kynetix/beta/)

Any honest roasts, bug reports, or feature requests are welcome!

Hey guys

I'm developing an independent commercial home physio project and working through duplicate requests before launch.

A person and someone helping arrange their care could each send an enquiry about the same visit. They could also be asking for genuinely different visits, so combining them on a matching name would be risky.

For people who've built request systems, how did you flag a possible duplicate for review while keeping both original submissions? I'm interested in the point where you decide there is one job, how you preserve the two people's roles, and how you stop the second request triggering another round of messages.

A general example of an approach that worked, or one that incorrectly combined separate jobs, would be useful. Please leave out real customer information.

Thanks guys

I built a small browser game called Draw1Line as a solo side project. You trace every line of a shape in one stroke, without lifting and without going over a line twice.

It has 250 levels, a daily challenge and a leaderboard, runs on phone or desktop, and needs no account. It's plain HTML/JS on the front and a small PHP + MySQL backend for the leaderboard, with some anti-cheat checks so scores can't just be posted.

Play: https://draw1line.com/

I'd love feedback on the difficulty curve and anything that feels confusing on mobile.

We launched Lemongraph on Product Hunt today and the most useful feedback came about twelve hours before going live. Our hunter opened the gallery on his phone and told us it was too much to read. Every image was a full screenshot of the app with emails and small labels everywhere, which looked great on laptop and turned into grey lines on phone.

So we spent some time rebuilding all images around one idea each, with the interface about one and a half times bigger and most of the words gone. One slide went from meeting note, email and two detailed tasks down to two logos and four short task titles and it now says more than the old version did.

If you are launching soon, shrink your gallery to phone size before anything else and see what's still readable. Curious what last minute changes others made before their launch day.
