About NodeInfo(2)
From the official readme · v3.1.0Description
NodeInfo is an effort to create a standardized way of exposing metadata about a server running one of the distributed social networks. The two key goals are being able to get better insights into the user base of distributed social networking and the ability to build tools that allow users to choose the best fitting software and server for their needs.
This plugin provides a barebone JSON file with basic “node”-informations. The file can be extended by other WordPress plugins, like OStatus, Diaspora or ActivityPub.
What information does this plugin share?
The plugin exposes the following public information about your site:
- Software: WordPress version (major version only for privacy)
- Usage statistics: Number of users, posts, and comments
- Site info: Your site name and description
- Protocols: Which federation protocols your site supports (e.g., ActivityPub)
- Services: Which external services your site can connect to (e.g., RSS feeds)
This information helps other servers in the Fediverse discover and interact with your site.
Supported NodeInfo versions
This plugin supports all major NodeInfo specification versions:
- NodeInfo 1.0 and 1.1 – Original specifications
- NodeInfo 2.0, 2.1, and 2.2 – Current specifications with extended metadata
- NodeInfo2 – Alternative single-endpoint format
Endpoints
After activation, the following endpoints become available:
/.well-known/nodeinfo– Discovery document (start here)/wp-json/nodeinfo/2.2– NodeInfo 2.2 (recommended)/wp-json/nodeinfo/2.1– NodeInfo 2.1/wp-json/nodeinfo/2.0– NodeInfo 2.0/wp-json/nodeinfo/1.1– NodeInfo 1.1/wp-json/nodeinfo/1.0– NodeInfo 1.0/.well-known/x-nodeinfo2– NodeInfo2 format

- If you wish to control the placement and the process of installing a WordPress Plugin.
- If your server does not permit automatic installation of a WordPress Plugin.
- If you want to try the latest development version.
Installation of a WordPress Plugin manually requires FTP familiarity and the awareness that you may put your site at risk if you install a WordPress Plugin incompatible with the current version or from an unreliable source.
Backup your site completely before proceeding.
To install a WordPress Plugin manually:
- Download your WordPress Plugin to your desktop.
- Download from the WordPress directory
- Download from GitHub
- If downloaded as a zip archive, extract the Plugin folder to your desktop.

wp-content/pluginsfolder in your WordPress directory online. - Go to Plugins screen and find the newly uploaded Plugin in the list.
- Click Activate to activate it.
Frequently asked questions
Why do I need this plugin?
If you want your WordPress site to be part of the Fediverse (decentralized social networks like Mastodon), this plugin helps other servers discover information about your site. It works together with plugins like ActivityPub to make your site fully federated.
Is any private information shared?
No. Only public information about your site is shared, such as your site name, description, and post counts. No personal user data or private content is exposed.
How can I verify it’s working?
Visit https://yoursite.com/.well-known/nodeinfo in your browser. You should see a JSON document with links to the NodeInfo endpoints.
Can other plugins extend the NodeInfo data?
Yes! This plugin is designed to be extensible. Other plugins can use WordPress filters to add their own protocols, services, or metadata. For example, the ActivityPub plugin automatically adds activitypub to the supported protocols list.
How do I know if everything is configured correctly?
Go to Tools > Site Health in your WordPress admin. The plugin adds two health checks: NodeInfo Well-Known Endpoint – Verifies that /.well-known/nodeinfo is accessible NodeInfo REST Endpoint – Verifies that the NodeInfo 2.2 REST endpoint returns valid data If either check fails, you’ll see recommendations on how to fix the issue.
