ByteJSON / browser-native developer tools

Debug the payload.
Keep the project private.

Focused tools for the moments that slow a build down: invalid JSON, SQL that will not parse, Firebase configuration, and schema drift. Your input stays in the browser.

The ByteJSON rule

Useful before it is clever.

Tools stay intentionally narrow: they should solve a real data, SQL, or configuration task without turning a private debugging session into an account signup or file upload.
