Run multiple AI coding agents in parallel using git worktrees, without conflicts. Agentastic is a native macOS code editor built specifically for AI agentic coding workflows. Written in Swift and SwiftUI, it gives you a lightweight environment where multiple AI coding agents can work simultaneously — each in its own isolated branch — without interfering with your work or each other. ## The problem with traditional IDEs Traditional IDEs weren't designed with AI agents in mind. When you try to run multiple AI coding assistants in a standard editor, you quickly run into problems: * **Conflicts** — Multiple agents editing the same files leads to chaos * **Blocked workflow** — You can't work while an agent is making changes * **No isolation** — One agent's mistakes affect everything in your project * **Missing context** — Agents don't understand your project's branch structure ## How Agentastic solves it Agentastic uses **agent isolation through git worktrees**. Every AI agent gets its own complete checkout of your repository on a separate branch. This means: * **One branch per agent** — Each agent works in its own git worktree, a full copy of your repo * **Zero conflicts** — Agents can't overwrite each other's work because they're on separate branches * **Keep coding** — You stay productive in your main workspace while agents run in the background * **Easy review** — Inspect exactly what each agent changed using the built-in diff viewer ## Architecture Each agent branch lives alongside your main branch as an independent worktree. When an agent finishes, you review the diff and merge if you're satisfied. ``` Your Repository | |-- main branch (your workspace) | |-- feature-auth (Claude agent) | |-- feature-api (Codex agent) | |-- bugfix-login (Another Claude agent) ``` ## Key features ### Agent management * **Git worktrees** — Automatic worktree creation for each agent * **Docker containers** — Optional container isolation for maximum security * **Agent Home** — Launch multiple agents with a single prompt * **Parallel execution** — Run Claude, Codex, and other agents simultaneously ### Development environment * **Native macOS** — Built for macOS 14+ with Apple Silicon optimization * **Ghostty terminal** — GPU-accelerated terminal with smooth rendering * **100+ languages** — Syntax highlighting and LSP support * **Fast performance** — Lightweight app with quick startup ### AI integrations * **Claude Code** — First-class support for Anthropic's Claude * **Codex** — OpenAI Codex integration * **Command Code** — Langbase Command Code integration * **Custom agents** — Add any TUI-based AI agent * **Code review** — AI-powered code review before merging ## Who Agentastic is for Agentastic is built for developers who want to move faster with AI. It's a great fit if you: * Use AI coding assistants and want to run multiple agents in parallel * Need safe, isolated environments for experimenting with AI workflows * Are frustrated with single-threaded AI coding and want to increase your throughput ## Next steps Get Agentastic running on your Mac in minutes with Homebrew or a manual DMG install.
