Maker
📌
This tool was built to make secure key generation simple and instant.
Instead of relying on external services or complex setups, everything runs directly in your browser using secure randomness. You can generate API keys, JWT secrets, UUIDs, and strong passwords in seconds.
No accounts, no tracking, no delays — just fast and private key generation for developers and builders.
Feedback is welcome, especially on what additional key formats or security tools should be added next.

How are the keys actually generated under the hood, like is it using WebCrypto with proper entropy or a custom PRNG?

Made a JWT secret in under a second, ran it through a validator and it worked first try. Love that everything stays in the browser, no sketchy uploads.

Useful little tool, the client-side generation gave me peace of mind for spinning up a JWT secret. Worked fast and didn't try to push me into signing up, which I appreciate.

Runs right in the browser with zero setup, and the client-side generation actually feels reassuring for sensitive keys. Liked that it covers JWT secrets and UUIDs in one place without making you pick through options.

Really handy for spinning up JWT secrets on the fly without bouncing between sites. Loved that everything runs locally so nothing leaves the browser.
