How can I install a custom node on the web version of n8n?

The in-app settings for installing community nodes (found under Settings > Community Nodes) is only meant for nodes published on npm and verified by us. Custom nodes—like ones you build locally—aren't supported through the UI of the web version.

If you're running a self-hosted instance (or using Docker), you can install custom nodes manually. For example, when testing locally you can follow these steps:

1. In your custom node's directory, build and link your package:

   SHCopied
   npm run build
   npm link

2. Go to the nodes folder in your n8n installation (usually ~/.n8n/custom/ unless you set a custom path) and link your node:

   SHCopied
   npm link <node-package-name>

3. Restart n8n so it loads the custom node.

For Docker users, you’d need to build a Docker image that copies your node’s built files into the custom nodes directory.

In short, the web version does not offer a button or setting to install custom nodes because that functionality is designed to be done via manual installation on your self-hosted instance.
