Ungate is a Cursor extension that lets Cursor use provider subscriptions through a local proxy and a public tunnel, instead of direct API billing. Right now it supports Claude and GPT via OAuth, and MiniMax via API key.

The main reason this exists is that Cursor can talk to a custom OpenAI-compatible endpoint, but its backend cannot reach localhost, so the extension manages the proxy + tunnel + provider auth flow for you.

Known limitation: this only works reliably with custom model IDs configured through the Ungate dashboard. Cursor’s built-in model IDs can bypass the custom base URL.
