As developers, we waste hours on repetitive micro-tasks. JSON formatting, Base64 encoding, UUID generation — individually trivial, collectively a time-sink.
I built a collection of 13 free, browser-based developer tools that handle these instantly. No install, no server upload, 100% local processing.

- JSON Formatter — Beautify, validate, and minify JSON
- JSON Schema Validator — Validate data against JSON Schema specs
- Text Diff Checker — Compare two texts line-by-line
Encoding Tools
