What it does
Built around a few ideas
For everyday work
The small conversions and inspections you reach for constantly, in one place.
Runs in your browser
Paste in whatever you are debugging. It is processed locally and never sent anywhere.
No install, no account
Open the page and use it. Nothing to sign up for and nothing to keep updated.
Questions
Before you click through
Is DevKit free?
Yes, and there is no account or sign-up at any point.
Is it safe to paste sensitive data — API keys, tokens, real JSON payloads?
Everything is processed in your browser with JavaScript. Whatever you paste is never sent to a server, so it stays on your machine.
Do I need to install anything?
No. It runs entirely in the browser tab — nothing to install, nothing to keep updated.
