Aizen
Agentic. Parallel. Native.
Aizen is a native macOS workspace for parallel development where each project or branch gets its own isolated environment with terminals, file tabs, browser tabs, and agent sessions. It runs Claude Code, Codex, OpenCode, Gemini, and other ACP agents side by side with full context isolation and MCP server integration via a built-in marketplace. Built in Swift/SwiftUI with a GPU-accelerated (libghostty) terminal, it is open source under GPL-3.0 with optional paid Pro tiers.
