Here are some features I shipped for BiteTube this week:

• Added a dedicated “Why it’s worth watching” section so you don't have to watch videos just to end up closing them
• Built “Continue the Vibe” dynamic discovery which helps user stay on the same vibe of content
• Polished up the UI to improve user experience
• Integrated Sanity as the CMS to make managing content easier and efficient

Share what kind of features you shipped in the comments to let other users know about your project!

I built MindRushGames, a free browser game where you test your memory through color, shape, sound and number challenges. Each game has 5 quick rounds, gives you a final score, and lets you see how precise your memory really is.

Hey everyone,

I was tired of "free" online tools that are actually behind a paywall, require an email for a simple PDF conversion, or track every click. So, I built Nolimify.

It’s an all-in-one toolbox for common tasks, built with a "zero-friction" philosophy.

• Web:https://nolimify.com/
• Repo: https://github.com/sarthakworks/sarthakworks.github.io/tree/gh-pages

What’s inside:

• PDF Tools: Merge, Split, Compress (All client-side where possible).
• Image/Video: Converters, resizers, and basic editors.
• Coding: JSON formatters, Base64, Unit converters, etc.
• P2P Chat: Secure, direct chatting without servers storing your logs.

Why use it?

1. No Signup: I don't want your email. Just use the tool.
2. No Tracking: No analytics or creepy scripts.
3. Open Source: You can see exactly how your data is handled.
4. Fast: Lightweight and loads instantly.

I’m looking for feedback on what tools I should add next. If you find a bug or have a suggestion, let me know!

Started as a simple question, what celebrity has the same birthday as me and what events happened on my birthday? Ended up building a this site.

You enter your birthday and city and it shows you:

Famous people born the same day as you, actual weather temperature on your birth day, top songs and films from your birth year, what $0.001 in Bitcoin in 2009 is worth today, your life in numbers, days lived, heartbeats, earth orbits. A timeline of world events you actually lived through

No sign-up, completely free, works on mobile. Curious what famous people share your birthday - bornhistory.com

Yes. You read that right.

Created this website, to answer your weird questions which can have a butterfly effect, ripple or domino effect and will give you curated answers.

Trust me it’s funny, try it out. You can share your questions which your answers with the share button too.

Please tell me how it goes and open to feedback and suggestions!

I’ve been playing around with vibe coding apps lately and it’s honestly crazy how fast you can build things now.

But I keep running into this problem, Just because something works, doesn’t mean the UX is actually good.

Sometimes:

• flows feel a bit confusing
• it’s not clear what to do next
• everything works, but still feels off

And as the person who built it, it’s hard to notice these things.

I’ve been looking into this more and even started building a small tool called My Design Audit to catch UX/UI issues early (mainly for my own projects).

Curious how others here deal with this
Do you just rely on feedback, or do you have some way to check UX before users drop off?

I made a thing. it's called utilitykit.tools.

it's like 200+ small utilities in one place — text tools, dev stuff, calculators, image and pdf tools, generators, whatever. the kind of stuff you google and end up on some sketchy site with 14 ads and a cookie banner the size of your screen.

i spent way too long planning it and then vibe-coded most of it tool by tool. some tools turned out really nice. some are probably broken in ways i haven't noticed yet. i genuinely don't know which is which at this point because i've been staring at it too long.

stuff that's actually true about it:

• it's free. forever. not "free for now." just free.
• no signup. no email. no nothing.
• it's actually fast. i was kind of insane about page size.
• most tools run in your browser so if you wanna throw in a private pdf or some json with secrets in it, nothing gets uploaded anywhere. it just runs locally.

what i'm asking:

please just look at it and tell me what's bad. seriously. i need fresh eyes. if a tool is broken tell me which one and i'll fix it tonight. if the design is ugly tell me. if a tool feels useless tell me. if you wish a specific tool existed drop the name in the comments and i'll add it, i mean that.

i know "review my side project" posts are a dime a dozen here but i've put a lot into this and i'd really appreciate even one comment.

thanks for reading this far genuinely

I built Mini Tool https://minitool.dev – a free, browser-based PDF toolkit where files never leave your browser with 14+ tools.

The core idea: every other free PDF tool uploads your files to their servers. For contracts, medical records,or anything sensitive that's a real problem. Mini Tool processes everything locally using pdf-lib and PDF.js running in Web Workers.

Tools included:Compress, Merge, Split, Rotate, Organize, Protect, Unlock, Watermark, Sign, Repair, Images to PDF,Booklet Optimizer,Smart Print Mode,Batch Processing, Workflow Builder.

The hardest technical challenge was getting reliable PDF processing in Web Workers across different filetypes and sizes some PDFs with embedded fonts or complex image compression would crash the worker silently.

Built this solo over several months. Would love technical feedback especially on the PDF processing approach and whether the privacy angle resonates with the crowd.

I'm building a multilingual travel platform built around free interactive tools instead of articles. Packing list builders, country comparison tools, budget calculators, vaccine and health maps. All free, all built to rank on organic search.

The model behind it: travelers never pay. Booking platforms, airlines, insurance companies, and tour operators pay affiliate commissions when someone books through the site. The traveler planning a trip to Japan doesn't need a subscription — they need a good tool that actually helps them prepare. When they book the JR pass or a hostel through it, the company covers the cost.

The bet is that interactive tools compound better in search than evergreen articles, and that trust is easier to build when you're not asking people for money up front.

For example: https://pack-lightly.com/tool/

Probably obvious to some, but it's a different starting point than most travel content I see — would be curious whether anyone else here has gone the tool-first route and whether the SEO actually holds long-term compared to traditional content.

I kept delaying building a portfolio because it felt like copying my CV into a website and tweaking layouts for hours. So I built a tool to automate it (myseera).

You upload your resume and it extracts your experience, skills, and projects, then generates a site you can edit and publish.

What it does right now:

• Generate a portfolio from a PDF or DOCX
• Structure content into clean sections
• Edit inline and switch between templates
• Publish to a live link or your own domain

Some things were harder than I expected:

• Resumes have no standard format so parsing is messy
• AI sometimes changes wording or groups things oddly
• Fitting real CV data into templates without breaking layout

Built this because most tools I tried felt too manual or asked for payment too early. Not sure yet if people would actually rely on something like this long term. Happy to get feedback or answer questions.

A few weeks ago, I had to do some troubleshooting on a borrowed Windows laptop. I quickly realized that getting a code snippet from my Mac to that PC meant logging into my email just to copy and paste one line of text. It drove me completely crazy.

So, I built Anydrop a free, completely browser-based WebRTC app that bridges the gap across ecosystems with zero downloads, accounts, or cloud storage.

The Core Features:

• Auto-Discovery: Devices on the same Wi-Fi pair automatically.
• P2P File Drops: Drag and drop files of any size directly between screens.
• Live Clipboard Sync: Hit Cmd/Ctrl + V anywhere on the screen to instantly sync text and links across connected devices.
• Secure Chat: Tap a connected device for an end-to-end encrypted chat and voice notes.

How it's Built:

• Pure P2P (WebRTC): Data travels through an encrypted tunnel directly from Device A to B. The second you close the tab, the session is wiped. Zero databases.
• Infrastructure: A lightweight Node.js signaling server hosted on Railway handles the initial handshakes, while Cloudflare's enterprise TURN servers act as a safety net for strict firewalls and remote connections.

It is 100% free to use with no ads. I would absolutely love for you to test the site and let me know what you think of the UI or if you hit any bugs! Thank you for reading.
