OpenCode
Open-source, provider-agnostic AI coding agent for terminal, desktop, and IDE.
MIT-licensed alternative to Claude Code. Switch between 75+ LLM providers, run Build/Plan agents, and keep code local — terminal, desktop, or IDE extension.
Multica
Universal AI agent framework — 50+ service integrations.
MIT-licensed agent platform with API, database, email, calendar, and cloud storage connectors. Multi-step workflows with memory and error recovery.
Void
Open-source Cursor alternative — VS Code fork with direct LLM access and no proprietary backend.
Apache-2.0 AI code editor with Agent/Gather modes, Tab autocomplete, and Ollama support. Your code goes straight to the provider — not through Void servers.
Kilo
Open-source agentic engineering platform — 500+ models in VS Code, JetBrains, and CLI.
MIT-licensed alternative to Cursor. Architect, Coder, and Debugger modes with MCP marketplace, browser automation, and optional API keys via Kilo Gateway.
PearAI
Open-source AI code editor — VS Code fork with Continue-based chat and model router.
Apache-2.0 alternative to Cursor. Local codebase context, BYOK or PearAI Router subscription, familiar VS Code experience with integrated AI.
Compare GitHub Copilot alternatives
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.
FAQ
Is there a free, open-source alternative to GitHub Copilot?
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.
