Agentastic vs Warp
Warp has grown from an AI terminal into what it calls an agentic development environment: a Rust terminal with the Warp Agent, a built-in code editor, a Code Review panel, support for third-party CLI agents, and cloud agents. Its client is open source under AGPL-3.0. Agentastic starts from the other end: a native macOS workspace whose unit of work is an isolated task, with a worktree, container, SSH host, or cloud VM per agent, Ghostty terminals, a browser agents can drive, and review before merge. If you want one excellent terminal on every OS, Warp is the stronger pick; if you manage a fleet of agents on a Mac, Agentastic is built for that.
Who should choose each option#
Agentastic
Choose Agentastic if your day is organized around several agents producing diffs you review and merge, and you want each task isolated automatically on a Mac.
Warp
Choose Warp if you want a polished, open-source terminal on macOS, Windows, or Linux, with its own agent, a light editor, and code review next to your shell.

| Editor | Built-in editor with LSP, plus one-click handoff to external IDEs | Built-in editor with LSP and a file tree |
| Code review | Diff viewer plus Claude, Codex, CodeRabbit, or Greptile review passes | Code Review panel with inline comments agents can act on |
| Cloud agents | Modal, Fly.io, or Vercel Sandbox on your own account | Warp cloud agents (limited on Free); Warp Factories in early access |
| Price | Free | Free; Build from $20/mo; Max from $200/mo; Business from $50/user/mo |
Pricing#
Agentastic
Free. Bring your own agent subscriptions.
Warp
Free plan with the terminal, the Warp Agent CLI, and bring-your-own inference. Build starts at $20 a month with included agent credits, Max at $200, and Business at $50 per user per month for up to 25 seats; Enterprise is custom.
Using them together#
Use Warp as your everyday terminal, and run the Warp Agent CLI as one of the agents inside Agentastic worktrees. Agentastic keeps a Ghostty terminal scoped to each agent's worktree, and its Open in button can open the current worktree in Warp.
Frequently asked questions#
Is Warp open source now?
Warp's client is open source under AGPL-3.0, with the code at warpdotdev/warp. Agentastic is free but closed source.
Is Agentastic a Warp alternative?
For agent work on a Mac, yes: Agentastic runs Claude Code, Codex, the Warp Agent CLI, and 50 more agents in isolated worktrees with review built in. For a general-purpose terminal on Windows or Linux, Warp is the better choice; see Warp alternatives for others.
Can I run Claude Code or Codex in Warp?
Yes. Warp detects third-party CLI agents such as Claude Code, Codex, and OpenCode and adds a rich input editor, notifications, and code review around them (docs). Agentastic runs the same CLIs, each in its own worktree or container, so parallel runs never share a checkout.
Does Warp support git worktrees?
Warp recognizes worktrees you create and gives each one code review and agent support. Agentastic creates the worktree for you when you launch a task, runs your setup script, and lets you remove or archive it when you are done.
Can I run the Warp agent inside Agentastic?
Yes. The Warp Agent CLI is one of Agentastic's built-in agent definitions: Agentastic starts it with unattended approval when you ask for it, and types your opening prompt once its interface is ready.
Does Warp run on Windows and Linux?
Yes, Warp runs on macOS, Windows, and Linux. Agentastic runs only on macOS 14 or later, though its agents can work on Linux machines over SSH or in cloud VMs.
How much does Warp cost?
Warp has a free plan; Build starts at $20 a month, Max at $200, and Business at $50 per user per month (pricing). Agentastic is free, and you pay your agent providers directly.
