Every developer needs quick tools — JSON formatter, Base64 encoder, JWT decoder, regex tester, PDF compressor, GIF maker. But I always hesitated to paste sensitive data into random tool sites. Where does that data go?
So I built ToolsStack — 21 tools that run 100% in your browser.
The tools
💻 Developer: JSON Formatter, JSON→CSV, Base64, URL Encode, HTML Entities, JWT Decoder, SQL Formatter, Regex Tester, Hash Generator (MD5/SHA), Diff Checker, PDF Compressor, PDF→JPG
⚡ Generators: UUID, Password, Lorem Ipsum
📝 Text: Word Counter, Case Converter, Markdown Preview
🎨 Image: Color Picker, QR Code Generator, GIF Maker
Why another tool site?
100% client-side — nothing leaves your browser
No signup, no ads, no tracking
Vanilla JS + Canvas API — no bloated frameworks
Deployed on Cloudflare Pages — fast everywhere
Try it: toolsstack.org
Source on GitHub (update with actual repo)
I'd love to know what tools you'd want added next!
