Use this guide to configure Open WebUI with CometAPI by setting the base URL, API key, and model or provider options. Open WebUI is a self-hosted web interface for AI models. Configure it to use CometAPI as an external OpenAI-compatible connection.
- Open WebUI running (self-hosted or via the demo at open.zetatechs.online)
- A CometAPI account with an active API key
Log in to the CometAPI dashboard. Click Add API Key and copy your key and base URL (https://api.cometapi.com).
In Open WebUI, go to Admin Panel → Settings → External Connections. Enable External Link OpenAI API, enter https://api.cometapi.com/v1 in the API Address field, paste your key into the Key field, and click Save.
Start a chat and send a test message. A successful reply confirms the integration is working.
