Do I need to create an account?
No. MADRE has no accounts, no servers and no cloud. It uses the sessions your AIs already have on your computer.
Which AIs does it work with?
Codex, Claude Code, Gemini CLI, Cursor and OpenCode. If you install Ollama, also @madre, your local AI. It answers with what the project remembers and changes nothing.
How much does it cost?
For individuals and teams of up to 10, nothing, also if you work for clients. Larger organizations, or anyone who wants to offer MADRE as a service, need a commercial license. Each AI uses your own account and limits with its provider, as you already do today. The details are in the license.
Is it open source?
The code is in plain sight on GitHub and you can read, change and share it. From 1.1 it uses the Business Source License 1.1, which is not an open source license: each version moves to the GNU AGPL v3, which is, four years after it is published. Versions up to 1.0.5 keep theirs.
Does it work on Windows?
Yes. Download the installer at madre.run/en/windows, double-click it and you’re done: it sets up WSL2, the Linux that comes with Windows, without you opening a terminal. If you prefer the terminal, the steps are in Install › Windows.
What does the Coordinator do?
It’s an AI that lives in Home. It reads what your projects learned, only the ones you connect, and tells you which project each fact came from. If you let it, it carries tasks from one project to another, up to #2. Anything that needs more permission reaches you as a proposal, and you decide.
Does my code leave my computer?
MADRE runs on your computer. What an AI reads travels to its provider with your account, just as if you used it in your Terminal, and does not go through MADRE. What MADRE sends on its own you see and turn off in Settings: the daily check for new versions and the anonymous errors (what failed and how much it’s used, with nothing you write and nothing from your projects). Also, once a day it says it is still in use, and that notice cannot be turned off: a random id, the version, the system and the Node version.
What if an AI changes something I didn’t want?
If you say nothing, the AIs only read. For them to edit, you raise the permission to #3 Edit. Before editing, MADRE takes a restore point, and Undo takes the project back to that moment.
Which Node version do I need?
Node 22.5 or newer. The automatic tests run on Node 22 and 24, on macOS and Linux.
Who makes MADRE?
I do, Jossué Alcalá. I make it and I read every report that comes in.
