Browse focused developer utilities for formatting, encoding, decoding, validating, generating, and comparing everyday web data. Most tools run in the browser; avoid pasting production secrets unless the individual tool clearly supports that use case.
Search by job or format, then open the exact tool route for the data you need to inspect.
Privacy note: use synthetic samples for JWTs, API keys, customer records, private documents, and regulated data unless the specific tool says exactly what stays local and what is sent over the network.
