What is aizen?
Aizen is an agent-centered development workspace for macOS that creates an environment for each project or branch, with its own terminal, files, browser, agents, and state. It runs ACP agents such as Claude, Codex, and Gemini inside the workspace, and lets you add MCP servers from an in-app marketplace. It provides a GPU-accelerated terminal, Git staging, commits, diffs, PR review, and GitHub Actions and GitLab CI status in one place. The code is open under GPL-3.0 and the core features are free.
