GitHub Copilot is GitHub's (a Microsoft company) proprietary AI pair-programming assistant, built into VS Code, JetBrains, and other editors via a paid subscription. It now supports models from multiple providers (GPT, Claude, Gemini), but access is still gated behind GitHub's per-seat pricing — there's no self-hosted or bring-your-own-infrastructure option.

Open-source alternatives let you get the same kind of AI coding help without a GitHub subscription, using your own API keys or local models instead. None of them bundle model access into a subscription the way Copilot does, so factor that cost in separately from the tool itself.

Yes. OpenCode, Void, Kilo, and PearAI are all open source. Model usage still costs money unless you connect a local model.

What's the best open-source alternative to GitHub Copilot?

OpenCode works across multiple environments rather than being tied to one editor, which makes it the most flexible pick.

Can I use GitHub Copilot alternatives with my own AI model?

Yes. OpenCode, Void, and Kilo all let you bring your own API keys or connect local models, without paying for a GitHub Copilot seat.
