FAQ

About Windsurf++
What You May Want to Know

Learn about product positioning, protocol support, local data, platform requirements, and uninstallation.

What is Windsurf++?

Windsurf++ is a BYOK integration for Windsurf and Devin that uses a cross-platform CLI, extension, and local proxy to connect custom model APIs, local inference servers, and compatible gateways.

Which model API protocols does Windsurf++ support?

It supports OpenAI Chat Completions, OpenAI Responses, Anthropic Messages, and Google Gemini APIs, including compatible services that implement these protocols.

Are provider API keys uploaded to a server?

Provider API keys are stored locally in ~/.cwindsurf/providers.json by default. Device signing leases do not contain provider API keys.

Which platforms does Windsurf++ support?

The installer supports macOS on Apple Silicon and Intel, Windows, and Linux. Node.js 18 or later is required.

How do I uninstall Windsurf++?

Run cwindsurf uninstall to remove the patches and extension. The installer creates backups before modifying application files.

Is Windsurf++ an official product?

No. Windsurf++ is not an official product of Windsurf, Devin, Codeium, or any model provider. Applicable application and service terms still apply.
