Aizen nails parallel development for macOS developers who live in multiple branches and run AI agents. The native performance and per-environment isolation are genuinely useful. But the Apple Silicon lock-in and lack of collaborative editing mean it's a specialized tool, not a general-purpose IDE replacement.

How we score →Aizen is a native macOS workspace built for parallel development. It lets you run AI agents (Claude, Codex, Gemini, and others via the Agent Communication Protocol) alongside terminals, file browsers, and web browsers—all scoped to individual projects or branches. Each environment keeps its own state, so you can switch between tasks without losing context. The app features a GPU-accelerated terminal (powered by libghostty) with split panes, themes, and optional tmux persistence. Git operations like staging, committing, diffing, and pull request review are integrated, along with tracking for GitHub Actions and GitLab CI runs. Aizen is open source (GPL-3.0) and free to use, with optional Pro ($59/yr or $5.99/mo) and Lifetime ($179) tiers for those who want priority support and future extras. It's Apple Silicon only and leverages Metal rendering for a responsive, native feel. Unlike web-based or cross-platform tools, Aizen is purpose-built for macOS users who need to manage multiple parallel workflows—running agents in one environment while reviewing code in another.
Aizen is a thoughtful answer to a real problem: context-switching across branches and projects when you're running agents, terminals, and browsers. The per-environment isolation is the killer feature—each branch gets its own terminal panes, file tabs, browser tabs, and chat history. We'd reach for this when reviewing a pull request on one branch while an agent refactors another. The GPU terminal feels snappy on Apple Silicon, and the built-in MCP server marketplace means you can wire up agents without leaving the app. Where it bites is the platform lock-in: this is macOS-only, Apple Silicon specifically. If you're on an Intel Mac, Linux, or Windows, look elsewhere. Also, there's no real-time collaborative editing—great for solo or async work, but not for paired programming or team debugging sessions. Compared to tools like Warp or Hyper, Aizen is less a terminal emulator and more a full workspace with agents and Git built in. Compared to Cursor, it's far less of a code editor—it's an environment orchestrator. The free tier is generous (full core features forever), so trying it costs nothing but a download. In practice, the value grows with your project complexity; a single-project developer won't get much out of it. For the parallel development crowd, it's a win.
