OpenCursor

The open source Cursor.

An open source AI code editor that works with whatever you already use. Plus 18 free models to start on.

Download for macOS Apple silicon GitHub

Free and MIT licensed. Also for Windows and Linux.

OpenCursor with a Cmd K edit open in cart.ts: the old line in red, the new one in green, Accept and Reject above it, and the model picker in the chat panel on the right.
A ⌘K edit, waiting for you to keep it. Built on Code-OSS, the open core of VS Code, so it feels like home. Settings and keybindings come over from VS Code or Cursor in one step.

Bring your own model.

Use what you already pay for, run a model on your own computer, or start free. Switch from the model menu at any time, even halfway through a conversation.

What's inside.

The parts of Cursor people use every day, open and in one place.

⌘L

An agent that asks before it acts.

Describe the change. The agent reads your code, edits files and runs commands, and checks with you before anything risky. Pick how it works with ⌘ .

AgentMakes the change, end to end
PlanAgrees on the approach first
DebugFinds the cause, then fixes it
AskAnswers without touching code

Edit in place ⌘K

Select code, say what should change, review the diff right there. Keep it or undo it.

Completion Tab

Suggestions as you type, from whichever model you pick for it.

Context @

Point the agent at files, folders, docs or your git changes.

Terminal ⌘K

Say what you want to run in plain words and get the command.

Checkpoints

Every agent step can be rolled back, files and all.

MCP

Connect MCP servers to give the agent tools beyond the editor.

Install.

Download the app, or paste one line into a terminal. The line picks the right file for your system and skips the first launch warnings.

Questions.

Is OpenCursor free?

Yes. OpenCursor is free and open source under the MIT license, with no account and no subscription. If you use a paid model, you pay that provider directly, at their price. With the free models or a local model, it costs nothing at all.

Is OpenCursor a free alternative to Cursor?

It is an independent, open source AI code editor with the workflow people use Cursor for every day: an agent chat with Agent, Plan, Debug and Ask modes, Cmd+K edits in place, Tab completion, @ context, project rules and MCP servers. The difference is that it runs on the model you choose instead of a subscription. It is not made by or affiliated with Anysphere, the company behind Cursor.

Can I use my Claude or ChatGPT subscription?

Yes. If you are signed in to Claude Code or the Codex CLI, OpenCursor drives it in the background, so the work counts against the Claude or ChatGPT plan you already pay for. Gemini CLI, Grok and OpenCode work the same way.

Which models can I use for free?

OpenCode's free models work with no account, installed in one click. On top of that, 18 models are free on the providers' own free tiers, from Groq, Google Gemini, Mistral, NVIDIA, OpenRouter, Z.ai and SambaNova; each needs a free key, and OpenCursor shows you how to get one. Free (auto) moves to the next free model when one reaches its limit.

Does it work with local models and offline?

Yes. Point it at Ollama, LM Studio or any OpenAI compatible server, on your computer or another one on your network. Nothing leaves your machine, and it keeps working without internet.

Is my code sent to OpenCursor?

No. There is no OpenCursor server in between: requests go from your computer straight to the model provider you picked, and API keys stay in your system keychain. Once a day the app sends an anonymous install count (a random ID, the version and the OS), which you can turn off in Settings.

Do my VS Code extensions and settings work?

OpenCursor is built on Code-OSS, the open source core of VS Code, so themes, keybindings and most extensions work as before. Extensions install from Open VSX, and your settings and keybindings come over from VS Code or Cursor in one step.

Which systems does it run on?

macOS on Apple silicon and Intel, Windows on x64 and Arm, and Linux as .deb, .rpm or .tar.gz on x64 and arm64. The app updates itself when a new release is out.
