Compare Cursor alternatives
Cursor is a proprietary AI-powered code editor built as a VS Code fork. It bundles model access into a subscription, which is convenient but ties you to Cursor's pricing and credit system, and the AI backend isn't open for inspection or self-hosting.
Open-source alternatives give you AI-assisted coding without that lock-in. Void is the closest match to Cursor specifically, since it's a VS Code fork built around the same workflow. OpenCode instead works across terminal, desktop, and IDE rather than being tied to one editor.
Since these tools mostly bring your own model (OpenAI, Anthropic, or local), factor in API costs separately from the editor itself — the open-source part removes subscription lock-in, not model usage costs.
FAQ
Is there a free, open-source alternative to Cursor?
Yes. OpenCode, Void, Zed, and Kilo are all open source. You still pay for whichever AI model API you connect them to, unless you use local models.
What's the best open-source alternative to Cursor?
Void is the closest match to Cursor specifically. OpenCode is the better pick if you want one agent that works across terminal, desktop, and IDE rather than a single editor.
Can I use my own AI model with an open-source Cursor alternative?
Yes, that's the main draw. OpenCode, Void, and Kilo all support bringing your own API keys or connecting to local models, rather than locking you into one provider.
