Open-source alternatives to Windsurf

Windsurf, the AI-native code editor originally from Codeium, went through a chaotic 2025 acquisition saga — a collapsed OpenAI deal, its CEO and top engineers hired away by Google, and the remaining company acquired by Cognition (makers of the Devin agent). As of June 2026, Cognition retired the Windsurf brand entirely and folded it into Devin Desktop, meaning the editor as "Windsurf" no longer exists as a separate product. It remains closed source throughout.

Void is the closest open-source equivalent — a VS Code fork with direct LLM access and no proprietary backend in between. PearAI is also VS Code-based and worth comparing if you specifically want Continue-based chat with a built-in model router.

FAQ

Is there a free, open-source alternative to Windsurf?

Yes. Void and PearAI are both open source and free to self-host. Note that Windsurf itself was discontinued and folded into Cognition's Devin Desktop in June 2026.

What's the best open-source alternative to Windsurf?

Void is the closer match to Windsurf's original approach — a VS Code fork that talks to LLMs directly with no proprietary backend routing your requests. PearAI is worth a look if you want Continue's chat interface with a model router built in.

Is Windsurf still available?

Windsurf was retired as a standalone product in June 2026 and merged into Cognition's Devin Desktop. Void and PearAI remain independent, open-source options if you want an editor that isn't tied to any one company's agent product.
