Relay
A secure bridge between your WordPress site’s internals and your monitoring tools.

Introduction
Relay is the spiritual successor to the WP Sites Monitor, rebuilt from the ground up with the insights we gained from that project. It’s designed to be an ultra-lightweight, no-frills WordPress plugin that gathers essential site data and passes it on to your monitoring tool of choice.
Tailored for developers and agencies — especially those who use Composer or automate plugin updates, Relay offers a streamlined way to keep tabs on sites without the overhead of bulky management plugins.
Relay vs Sites Monitor
The biggest change? Relay is purpose-built to only collect and relay site data (hence the name). There are no UI blocks, settings pages, or unnecessary API calls. This lean approach keeps the plugin focused, fast, and efficient.
You’re free to integrate it with any monitoring system, or use our own open-source tool, Hub. Best of all, Relay is completely free.
Getting started
Follow the steps below to install and start using the plugin.
1. Install and activate the plugin
Download the plugin from the WordPress plugin directory. Then, install and activate it via your WordPress dashboard.
2. Access the API endpoints
Once the plugin is active, you can access the API endpoint at: https://your-site.com/wp-json/relay/v1/core
Important: This endpoint is restricted to authenticated users with the manage_options capability. To authenticate your requests, we recommend using WordPress's Application Passwords feature.
3. Visualize the data
Use the API to collect data from your WordPress site and display it in your preferred monitoring tool. Alternatively, you can use our lightweight monitoring tool, Hub to visualize the data directly.
