Format, validate, encode, minify and hash — locally, so you can paste real data in.
There is a specific reason a developer utility should run client-side, and it isn't speed. It is that the things you paste into these tools are frequently things you should not paste into a stranger's server: a JWT from a staging environment, an API response with customer records in it, a config blob with a connection string, a minified bundle from a private repository. The convenient online formatter is a data exfiltration route that people use dozens of times a week without registering it as one.
Everything in this category runs in your browser. The JSON formatter parses with the native JSON engine, the encoders use the platform's built-in Base64 and URI functions, the hash tools use the Web Crypto API. No request carries your input anywhere, which means pasting production data into them is a defensible thing to do rather than something to feel uneasy about.
The JSON formatter is the workhorse, and it reports parse errors with position information rather than just refusing — which is usually what you need, since malformed JSON is almost always one trailing comma, one unquoted key, or one smart quote that a word processor introduced on its way through an email.
