All tools in one place.
Start with the task you need to finish: clean up JSON, inspect a token, decode text, test a regex, or check an endpoint.
Pick the thing you are trying to do, then open the closest tool.
JSON, JWT, Encode, API, and Regex keep similar tools grouped together.
Each page keeps the same basic layout so you do not have to relearn the interface.
