Agentastic vs Windsurf (now Devin Desktop)
Windsurf became Devin Desktop on June 2, 2026. Cognition kept the IDE, with its editor, extensions, Tab, and Supercomplete, and made an Agent Command Center the main view: Spaces, a Kanban board, local and cloud Devin agents, and third-party agents over ACP. Agentastic is a native macOS workspace built only around agents. It runs the real CLIs of Claude Code, Codex, Gemini CLI, and 50 more in isolated worktrees, containers, SSH hosts, or cloud VMs, then gives you a review surface before anything merges.
Who should choose each option#
Agentastic
Choose Agentastic if you want a free, native Mac app that runs any CLI agent with your own subscriptions and isolates each task in a worktree, container, SSH host, or cloud VM on your own account.
Devin Desktop (Windsurf)
Choose Devin Desktop if you want a full AI IDE on macOS, Windows, or Linux, with Supercomplete, Cognition's Devin agents locally and in the cloud, and ACP agents in the same command center.

Pricing#
Agentastic
Free. Bring the subscriptions or API keys for the agents you run.
Devin Desktop (Windsurf)
Free plan with a light agent quota and unlimited Tab completions. Pro is $20 a month (frontier models, Devin Cloud, ACP agents), Max $200 a month, and Teams $80 a month plus $40 per full seat; Enterprise is custom.
Using them together#
Devin Desktop can stay your editor while Agentastic runs other CLI agents in their own worktrees. Open an Agentastic worktree folder in Devin Desktop when you want to edit by hand; both work on ordinary git branches, so nothing ties a task to one app.
Frequently asked questions#
What happened to Windsurf?
On June 2, 2026, Windsurf became Devin Desktop. Cognition renamed it and kept the same IDE, settings, and plans (Devin Desktop FAQ), and windsurf.com now redirects to devin.ai/desktop.
Is Cascade still part of Devin Desktop?
The local agent is moving to Devin Local, which Cognition describes as an improved harness with subagents and sandboxing. Its FAQ says Cascade stayed available through July, and existing Windsurf rules still load.
Is there a free Windsurf alternative?
Agentastic is free on macOS and runs CLI agents such as Claude Code, Codex, and Gemini CLI with your own subscriptions. Devin Desktop itself also has a free plan with a light agent quota. For more options, see Windsurf alternatives.
Can Devin Desktop run Claude Code or Codex?
Through ACP, yes: its docs list Codex CLI, Claude Agent, Gemini CLI, Junie, and OpenCode as examples, available on Pro, Max, and Teams (ACP docs). Agentastic runs the full CLIs in their own terminals or as structured Chat, and the app itself is free; you pay only the agent providers.
Does Agentastic do inline completions like Supercomplete?
No. Agentastic hands whole tasks to agents and helps you review the result; it has no keystroke-level completions. If you want both, keep an AI editor for typing and use Agentastic for parallel agent work.
Does Devin Desktop isolate parallel agents?
Yes, with git worktrees for parallel tasks, plus Spaces to group the sessions, PRs, and files that belong to one task. Agentastic also uses worktrees by default and adds Docker or Apple containers, SSH hosts, and cloud VMs on your own Modal, Fly.io, or Vercel account.
