Json Bonito

A Firefox extension that opens a beautiful, full-tab JSON formatter and editor when you click the toolbar icon.
Why Json Bonito

Your data stays on your machine. Json Bonito processes everything locally in your browser — no data is ever sent to any server. Paste API responses, credentials, internal configs, or any sensitive payload without worrying about it leaving your machine.

Fast. It opens instantly as a browser tab and processes JSON using the browser's native engine. No loading screens, no network round-trips.

Simple. Paste JSON, press Ctrl+Enter. That's it.

Free software. Licensed under the BSD 2-Clause License. No accounts, no subscriptions, no telemetry.
