About DevPry

Why this exists and what we're building.

Why we built this

Many online developer tools are slow, full of ads, and in some cases ask you to sign up before you can even paste a JSON string. DevPry is the tool we wanted to use ourselves — fast, clean, and entirely in the browser. No accounts. No servers processing your data. No noise.

How we build tools

Client-side first. Everything that can run in your browser does. Your JWTs, Base64 strings, and commit messages never leave your machine.
Fast by default. No frameworks bloating the page. Tools load instantly and respond in real time as you type.
No sign-up, ever. You should be able to use a tool without creating an account. There is nothing to log in to.
Honest about what uses a server. The AI Prompt Debugger calls an external API — we say so clearly. No hidden data flows.
