About ToolPlanet
ToolPlanet is a free, privacy-first platform of essential developer utilities — built to be the fastest, most trustworthy toolbox for developers worldwide.
Our Mission
Developers shouldn’t have to choose between convenience and privacy. Many online tools send your data to servers for processing — meaning your JWT secrets, API keys, and sensitive code leave your machine.
We built ToolPlanet to be different: every tool runs entirely client-side using browser APIs. No servers process your data. No logs are kept. No accounts are needed.
Core Principles
Privacy First
Every tool processes data locally in your browser. Your code, tokens, keys, and data never leave your device. We don't log inputs, store sessions, or track usage.
Speed First
We target Lighthouse ≥95 with first-load under 1 second. Tools use browser-native APIs (Web Crypto, TextEncoder) for maximum performance without heavy dependencies.
Developer Focused
Built by developers, for developers. Every tool is designed to solve a real pain point — no fluff, no paywalls, no forced signups. Just tools that work.
Always Free
All 29+ tools are free forever. Infrastructure costs are near-zero thanks to Cloudflare Pages. Sustainable through privacy-respecting AdSense monetization.
