Ravnsight Detective is a free WordPress plugin that sees errors, changes and updates from inside the site – the things you can never see from the outside. It installs in a minute, and it makes no external requests until you choose to connect it to Ravnsight.
How to install
- Download the zip from the plugin page.
- In WordPress: Plugins → Add new → Upload plugin, choose the zip, click Install now, then Activate.
- Open Ravnsight in the admin menu. Nothing leaves the site yet – the core logs everything locally until you connect it.
Requirements
WordPress 6.4 or later and PHP 8.1 or later. The plugin is built for minimal overhead (target: under 5 ms and 2 MB on a typical cached request), so your visitors never notice it.
What you get right away, for free
Even in the free tier, Detective logs PHP errors, tracks every plugin, theme and core change, and lets you run isolation tests to pin down a suspect without touching your production site. For cloud correlation and diagnosis you then connect the site to Ravnsight (Pro) – see Connect a site to Ravnsight.
