I found myself opening 4–5 different websites every day for basic tasks like formatting JSON, decoding JWTs, comparing JSON responses, and converting YAML.
Eventually I decided to build a single place for all of it.
The result is JSONSift — a free browser-based toolkit for developers.
Features include:
JSON Formatter & Validator
JWT Decoder
JSON Diff
YAML ↔ JSON Converter
Base64 Tools
URL Encoding/Decoding
More utilities on the way
Everything runs locally in your browser, so your data never leaves your machine.
