Overview

What is Agentastic and why use it?

What is Agentastic?

Agentastic is a native macOS code editor designed specifically for AI agentic coding workflows. Built with Swift and SwiftUI, it provides a lightweight yet powerful environment where AI coding agents can work in parallel without stepping on each other's toes.

The Problem

Traditional IDEs weren't built for AI agents. When you run multiple AI coding assistants, they often:

  • Conflict with each other - Multiple agents editing the same files leads to chaos
  • Block your workflow - You can't work while an agent is making changes
  • Lack isolation - One agent's mistakes affect everything
  • Miss context - Agents don't understand your project's branch structure

The Agentastic Solution

Agentastic solves these problems with agent isolation through git worktrees:

  • One branch per agent - Each AI agent works in its own git worktree, a complete checkout of your repository
  • Zero conflicts - Agents can't overwrite each other's work since they're on separate branches
  • Continue working - Keep coding in your main workspace while agents work in parallel
  • Easy review - See exactly what each agent changed with the built-in diff viewer

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 specifically 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 Integration

  • Claude Code - First-class support for Anthropic's Claude
  • Codex - OpenAI Codex integration
  • Custom Agents - Add any TUI-based AI agent
  • Code Review - AI-powered code review before merging

How It Works

Your Repository
    |
    |-- main branch (your workspace)
    |
    |-- feature-auth (Claude agent)
    |
    |-- feature-api (Codex agent)
    |
    |-- bugfix-login (Another Claude agent)

Each agent gets its own worktree. They can all work simultaneously without conflicts. When an agent finishes, review the diff and merge if satisfied.

Who Is Agentastic For?

  • Developers using AI coding assistants who want to run multiple agents in parallel
  • Teams experimenting with AI workflows who need safe, isolated environments
  • Anyone frustrated with single-threaded AI coding who wants to 10x their throughput
