I Built 20+ Free Dev Tools and a Flip Clock That Turns Old Phones Into a Desk Companion

The Toolbox → 0918.us (https://0918.us)
24 free browser-based tools. No signups. No ads. No tracking.

• Image: compressor, converter, cropper, resizer, favicon generator, Base64 converter
• Code: JSON formatter, JWT decoder, regex tester, SVG optimizer, SVG→JSX, hash generator, UUID generator, URL encoder/decoder, timestamp converter
• CSS: gradient generator, box shadow generator, clamp generator, color picker, contrast checker
• Text: case converter, lorem ipsum generator, Base64 text converter Why I built this I got tired of bookmarking 15 different sites for daily dev tasks. And I wanted a desk clock that didn’t cost $200. So I built both under one domain as a birthday project. Tech stack
• Next.js + TypeScript
• Deployed on Vercel
• Flip Clock uses CSS 3D transforms + setInterval sync You can use it today
• Flip Clock: open flipclock.0918.us on any device → full screen → done
• Tools: bookmark the tools you use most
• Everything is free, no accounts, nothing to install Plus, if you have something similar (free tools, desk clock, old device repurposing), I’d love to see it. Drop a link in the comments.
