Install

Download and install Open Free Max on Windows or Apple Silicon macOS.

OFM ships as a native installer. There is no package manager, no build step and no command line required.

Download

Grab the installer for your OS from the download section:

  • Windows — .msi (standard Windows installer; clean uninstall from Settings → Apps)
  • macOS — signed and Apple-notarized .dmg for Apple Silicon

The two platforms are not always on the same version. The download section states the version of each installer.

System requirements

  • Windows 10/11. Optional: a WSL2 distro to open Linux projects natively (see Native WSL2).
  • macOS 10.15+ (Catalina or later), Apple Silicon.
  • The agent CLIs you want to use must be installed and logged in (Claude Code, Codex, Antigravity, Cursor Agent, OpenCode, Vibe, Kimi). OFM detects them; if a CLI or its runtime (Node, Python + uv) is missing, the app shows a step-by-step installation assistant with copy-ready commands, an “open terminal” shortcut, and a re-check button — no manual PATH debugging needed.

First launch

The production release is signed on both platforms: Windows uses Azure Artifact Signing, and macOS uses an Apple Developer ID with notarization.

On macOS, open the DMG, drag Open Free Max IDE to Applications, then launch it normally.

Windows / SmartScreen

The Windows MSI is Authenticode-signed for production distribution. Windows should show APPS VELOCITY as the verified publisher; no SmartScreen bypass should be required.

Next steps

Continue with the Quickstart to open a project and run your first agent.
