A free, privacy-first GitHub Copilot alternative for VS Code — powered by local Ollama models. No API key. No subscription. No data sent to the cloud.
ACE-Codex is a VS Code extension that brings AI-powered inline code completion to your editor using locally running Ollama models. Everything runs on your machine — no subscriptions, no internet required, no code leaving your system.
Built by a developer who wanted Copilot-level assistance without the monthly bill.
