About Void

Void is an open-source fork of VS Code with AI built directly into the editor — chat, inline edits and agentic changes — designed as a drop-in replacement for Cursor that you actually control. You keep the VS Code experience, themes and extensions you already know, and gain AI features that respect your privacy.

The key difference from closed forks is transparency: you bring your own model or key, you can connect local models, and your prompts and code don't have to flow through a vendor's servers. It's the editor you know, with AI you own.

It's Apache-2.0 licensed and growing quickly. For developers who like Cursor's idea but want it open, private and model-agnostic, Void is the leading open VS Code fork.

Key features

AI built into the editor — Chat, inline edits and agent changes are native to the fork, not a bolt-on plugin.
Bring your own model — Use any provider or a local model, so prompts and code stay under your control.
Familiar VS Code base — Keep the VS Code UI, themes and extensions you already use.
Private by default — Your data doesn't have to pass through a vendor's cloud — connect local models if you prefer.
