OpenCode continues to improve the beta version of their desktop application for macOS, Windows, and Linux. It is positioned as a free alternative to proprietary tools like Codex, Cursor, or Devin and is actively developing.

Although the application is still in beta, the video author notes its speed, good design, and adaptability.

If you use the desktop version on Windows, it is better to run the backend (server-side) in WSL (Windows Subsystem for Linux) — there are currently open issues regarding integration improvements, but WSL already provides the most stable result. It offers significantly better file system performance, full terminal support, and compatibility with development tools.
