Cursor
Cursor is an AI-first code editor.
Compatibility Status
Not Compatible - Cursor has known bugs with custom OpenAI base URLs that prevent reliable use with third-party endpoints.
Known Issues
Cursor’s custom endpoint support is currently broken:
- Sends incomplete payloads resulting in 400 errors
- “Invalid Model” errors even with valid configurations
- The Cursor team is aware but has no fix timeline

Workarounds
Option 1: Use Cursor’s Native Subscription
If you need Cursor specifically, use their built-in AI features with a Cursor subscription.
Option 2: Use Alternative Editors
Consider these alternatives that work reliably with Extend Proxy:
| Tool | Type | Status |
|---|
| Continue | VS Code Extension | Working |
| Cline | VS Code Extension | Working |
| Roo Code | VS Code Extension | Working |
| OpenCode | CLI | Working |
Option 3: LiteLLM Proxy (Advanced)
For advanced users, you can set up a LiteLLM proxy as an intermediary. This adds complexity and is not recommended for most users.
Future Support
We will update this page if Cursor fixes their custom endpoint support. Check back for updates.
