Auto-detect and decode developer data formats instantly in your browser
Visit devtool.com ↗What is DevTool.com?
DevTool.com is a collection of 40+ free, client-side developer utilities that run entirely in your browser with no server uploads. Paste a JWT, Base64 string, timestamp, JSON, cURL command, or other encoded data, and the tool automatically detects the format and decodes it. The suite includes formatters for JSON, SQL, XML, and YAML; generators for UUIDs, passwords, and QR codes; converters between formats like JSON-to-TypeScript and cURL-to-Python; and security tools like JWT debugging and hash generation.
Designed for developers who need quick, private access to common encoding and conversion tasks, DevTool.com prioritizes client-side execution to keep sensitive operations off third-party servers. The maker says it was built with Gemini 3.
