About ToolsForDevs Pro
ToolsForDevs Pro is a free suite of 55 developer utilities covering JSON, XML, encoding, cryptography, and everyday text and data tasks. Every tool runs entirely in your browser — your data never leaves your device.
What we stand for
Privacy-first
Every tool runs in your browser. We never see, log, or store your input. There's no server-side processing — open the dev tools network tab and confirm for yourself.
Fast and free
No sign-up, no rate limits, no ads inside the tool UI. Everything is statically pre-rendered for instant load and ships with zero blocking JavaScript on the critical path.
Real cryptography
Our crypto tools use the browser's Web Crypto API and audited libraries. UUIDs come from the OS CSPRNG; passwords come from crypto.getRandomValues().
No tracking
We don't fingerprint visitors, sell data, or share what you do here. Aggregate analytics (page views, country) are the only signals we collect — never your tool input.
