About DevToolMage

DevToolMage is for programmers who need a fast, honest place to inspect developer primitives. The first tools cover JSON, Base64, URL encoding, UUIDs, hashes, JWTs, Unix timestamps, JavaScript regex, and Unix cron.

It is not a programming blog, an AI code generator, a file converter, a dataset cleaner, a webmaster suite, or a generic random-generator site. The tools run in your browser. Ads and analytics scripts are not loaded.
