Developer Tools

Every developer tool here runs entirely client-side. No paste box that ships your API response, JWT or production config to someone else's logs. JSON formatting uses native JSON.parse, hashing uses Web Crypto, and password generation uses crypto.getRandomValues, same primitives your own code would use.
