Developer Tools
JSON formatting, regex testing, encoding, code minification, and more for web developers.
37 free tools
A curated collection of utilities that developers reach for daily. From formatting messy JSON responses to testing regular expressions, from encoding data for URLs to generating UUIDs, these tools eliminate the need for installing CLI utilities or searching through documentation for syntax references.
Each tool is designed for quick, focused tasks: paste your input, get your output, and move on. The developer tools support common workflows like debugging API responses (JSON formatter, JWT decoder), preparing data for transmission (Base64, URL encoding), validating configurations (cron parser, JSON Schema validator), and generating boilerplate (UUID, meta tags).
All tools run entirely in your browser. This means you can safely paste API keys, tokens, or sensitive configuration data without worrying about server-side logging or data retention.
