Agentic Development Environment
Run 30+ parallel coding agents — Claude Code, Codex, Command Code, Gemini, Hermes Agent, Cursor, Copilot, Junie, OpenHands, and more — in complete isolation using Git worktrees or Docker containers. Each gets its own built-in IDE, Ghostty terminal, and browser. Review diffs and run multi-agent code review before you merge.

Key Features
32 Supported Agents
Agentastic auto-discovers coding agents installed on your system, including Hermes Agent. Any terminal-based agent works out of the box.
How it works
Agentastic.dev handles worktree creation and management.
Each worktree gets its own Ghostty terminals. Run Claude Code, Codex, Command Code, Gemini, Junie, OpenHands, or any of the 30+ supported agents in an isolated workspace.
See who's working, what needs attention, and review code with built-in diff and merge tools.

Frequently asked questions
Free without limits. No sign-up required. No strings attached. We don't charge for the agents. For Agents, you'll need agent subscriptions (Claude Code/Codex/Gemini/Junie/etc) or API access. You pay vendors (Anthropic/OpenAI/Google/JetBrains/etc) directly.
None. Agentastic.Dev does not collect, retain, or train on any of your data (usage, code, etc). Nothing, nada, zilch, null.
Each agent runs in its own isolated branch in Git worktree or docker container; they can work simultaneously without conflicts. You can monitor all agents in real-time and switch between them instantly.
Yes, each Agentastic workspace is a new git worktree. This allows each coding agent to work in complete isolation without conflicts.
We support 33 built-in CLI agents, including Claude Code, Codex, Command Code, Gemini, Hermes Agent, Cursor, GitHub Copilot, Junie, OpenHands, Letta Code, Cortex Code, OB-1, Amp, Droid, Goose, Aider, Cline, OpenCode, and more. Any terminal-based agent can also be added as a custom agent. We also support Claude, Codex, and CodeRabbit for code review. Want to see something else? Email us at hi@agentastic.ai.
Agentastic.dev requires macOS 14.0 (Sonoma) or later and runs on both Apple Silicon and Intel processors.
Right now Dev is still in closed development. But our goal is to build an open, community-driven ecosystem, and extensibility is on the roadmap. If you'd like to shape what that looks like, ping us on Twitter or join our Discord!
Dev supports hooks, including .agentastic/setup.sh, which executes upon worktree creation. You can setup your environment variables or copy them using this hook. See the documentation for more examples.
