The bigger picture: Developer
Developers lose a surprising amount of time to small tasks: formatting data, decoding tokens, converting between formats and checking syntax. Fast in-browser tools keep you in flow and keep sensitive data off third-party servers.
What's changing: AI coding assistants now write a lot of code, but developers still need quick, trustworthy tools to inspect and verify what comes out: formatters, validators and decoders matter more, not less.
Frequently asked questions
Can I reverse a hash?
No. Hashes are one-way. Don't use MD5 or SHA-1 for passwords.
