Hey Product Hunt! 👋
I'm the solo developer behind TimestampLab. I built this because I was tired of juggling 10 different bookmarks every time I needed to debug a log file, convert a timestamp, or generate a cron expression.
The goal was simple: build a toolkit that's fast, private, and actually pleasant to use.
🔒 **Privacy-first**: Everything runs in your browser. No data is ever uploaded — you can even disconnect your internet after loading the page and everything still works.
🎨 **Terminal-inspired design**: Because developers spend half their lives in terminals anyway. Dark mode by default, monospace fonts, green-on-black vibes.
🌏 **Bilingual**: Full English and Chinese support. I wanted to make sure non-English-speaking devs have access to quality tools too.
💰 **100% free, no ads**: This is a passion project. I might add a "Buy me a coffee" button someday, but the tools will always be free.
🛠️ **Tech stack**: React + Vite + Tailwind CSS, deployed on Cloudflare Pages. The entire site is ~200KB gzipped.
I'd love to hear:
- Which tool do you find most useful?
- What other time-related dev tools should I add next?
- Any bugs or UI papercuts?
Thanks for checking it out! ⏱️
