DevTools Suite
Privacy-first dev tools run in browser. No login no tracking
Free privacy-first developer tools that run entirely in your browser. JSON formatter & validator, JWT decoder, regex tester, cron expression generator, diff checker, and smart checklist. No login, no uploads, no tracking.
I built DevTools Suite because I kept running into the same frustration during day-to-day development work: most online developer tools either require uploads, track user data, add unnecessary friction, or feel overloaded for simple tasks.
One pain point that especially inspired this project was release management and deployment checklists. In real projects, missing a single release step can create production issues, rollback situations, or late-night debugging sessions. I wanted a lightweight checklist tool that feels fast, simple, and reliable without needing accounts or cloud sync.
That idea eventually expanded into a broader collection of browser-based developer utilities that all follow the same philosophy:
Everything runs locally in your browser
No login required
No data uploads
Fast and minimal UI
Privacy-first by default
Current tools include:
Smart Checklist Creator
JSON Formatter
Regex Tester
JWT Decoder
Cron Generator
Diff Checker
The project is built with Next.js and TypeScript, deployed on Vercel, and fully open source.
I’d genuinely appreciate feedback, feature ideas, bug reports, or suggestions from fellow developers. Thanks to everyone taking a look and supporting the launch.
