It’s 2025. If you’re still switching tabs to convert an image, record a voiceover, or write a slogan manually…
You’re working too hard.
Here’s a curated list of lightweight, smart, and indie-powered tools I use as a developer — to build, ship, and have fun along the way.
Most are built by solo devs or small teams (some of them mine 👋).
No bloat. No paywalls. Just tools that do one thing — well.
🎮 1. https://minicrossword.run/ — Micro Games for Micro Breaks
Daily crossword puzzles, optimized for your coffee breaks.
Built with React and Vite, it’s fast, clean, and surprisingly addictive.
Yes, I built it — and yes, I still lose sometimes.
🎬 2. https://textideo.com — Text-to-Video AI Studio
Turn prompts into cinematic videos and image sequences in minutes.
Whether you're building explainer videos or repurposing blog posts into TikToks, Textideo’s text-to-video pipeline saves hours.
Zero editing experience required.
✉️ 3. https://tempmail3.com/ — Disposable Email, Done Right

🌙 4. https://veo3.im/ — Sleep Tracker for Busy Minds
This one’s personal. I built Veo3 to help someone I love sleep better.
It’s a no-friction sleep note & mood tracker — private, simple, and calming.
Use it daily. Your brain will thank you.
