Add MagmaRouter to Open WebUI
Open WebUI is protocol-first: it treats any OpenAI-compatible endpoint as an OpenAI connection. Add MagmaRouter in the admin UI or through environment variables.
- Base URL
- https://api.magmarouter.com/v1
- API key
- Get one, starts sk-mr-
- Example model
- glm-5.3-xploded
Admin Settings, Connections
Go to Settings, then Admin, then Connections. Next to "Manage OpenAI API Connections", add a connection:
- URL: https://api.magmarouter.com/v1
- API Key: your sk-mr-... key
Leave Model IDs empty to auto-detect the catalogue, or set an allowlist to show only the models you want. Save, and the models appear in the selector.
Or environment variables
Shell
OPENAI_API_BASE_URL=https://api.magmarouter.com/v1 OPENAI_API_KEY=sk-mr-...
Open WebUI's default base URL is https://api.openai.com/v1, so keep the /v1 on the MagmaRouter URL. It caches the model list; saving the connection refreshes it immediately.
Pick a model
Each page has the Open WebUI setup with that model's id and limits filled in, and what a session costs.
