Plugin config validator

A malformed .json config is one of the most common — and most frustrating — reasons a Rust plugin silently won't load. Paste your config below and find the exact problem.

Everything runs in your browser — nothing is uploaded.

How to use it

  1. Open your plugin's config — carbon/configs/PluginName.json (or oxide/config/PluginName.json).
  2. Copy the whole file and paste it into the box above.
  3. If it's invalid, you get the line and column. Fix it, re-paste, confirm it's green, then save the file back and reload the plugin.

Still not loading after the config is valid? The problem is elsewhere — work through Carbon plugins not loading.
