About ApexApps.in
Free, fast, and privacy-respecting developer tools that run entirely in your browser.
Why we built this
Every developer has been there: you’re debugging a production issue at 2 AM, you paste a JWT into some random website to decode it, and you immediately wonder — did I just leak a token?
The best developer tools should be fast, always available, and most importantly, private. That’s why every tool on ApexApps.in runs entirely in your browser. Your data never leaves your machine.
