About SimpleDevTools

Free, fast, privacy-first developer utilities that run entirely in your browser.

What is SimpleDevTools?

SimpleDevTools is a collection of everyday developer utilities designed to be instant, clean, and completely private. There's no signup, no account, no ads that require registration — just open a tool and use it.

Every tool runs 100% in your browser. Nothing you type is ever sent to a server. This means your tokens, passwords, JSON payloads, and code snippets stay on your machine, always.
