About Our Developer Tools
Every developer needs reliable tools for formatting, encoding, decoding, and debugging. Our free developer tools are designed to streamline your workflow, whether you are working with APIs, debugging authentication tokens, or manipulating data formats.
All tools run entirely in your browser, which means your sensitive data never leaves your machine. This is especially important when working with JWT tokens, API keys, or proprietary data structures.
Common Developer Workflows
- API Development: Format JSON responses and validate data structures
- Authentication: Decode JWTs to inspect claims and verify token contents
- Data Encoding: Convert between Base64 and text for API payloads
- URL Building: Properly encode query parameters and URL segments
- Pattern Matching: Test and refine regex patterns before implementation
