Windsurf
Windsurf is an AI-powered code editor developed by Codeium, built on context-aware intelligence technology. It integrates features including auto-completion, a conversational AI assistant (Cascade), and terminal monitoring. Its core characteristic is a unified context system capable of sensing terminal state, clipboard contents, and project history, designed to provide developers with a coherent and intelligent programming assistance experience.

The AI coding tools supported by AI Design Skills include Claude Code, Cursor, Codex and Windsurf.
The ranking of free AI programming tools given in the article (from fifth to first: Cursor, GitHub Copilot, Windsurf, open-source extensions + Ollama, Google Antigravity) comes from the testing criteria of a single YouTube channel.
Windsurf came from Codium and, after being acquired by Cognition, was relaunched in June 2026 under the name Devon Desktop.
In June 2026, Cognition renamed its Windsurf editor to Devin Desktop and added the Agent Command Center, a Kanban-style panel for managing multiple agents in one place; it was released as a free update with existing pricing and settings unchanged.
Windsurf was renamed Devon Desktop after being acquired, and its quota policy is not public.
Devin Desktop's predecessor is Windsurf, which was renamed Devin Desktop after being acquired by Cognition.
The Windsurf free plan offers unlimited code completions, but the Agent quota is limited.
Heavy users/independent developers should consider the $10–20 per month paid tier, since the efficiency gains from Agents usually cover the cost.
windsurf.com now redirects directly to Devin; Cognition's Devin desktop app can manage local and cloud agent clusters from a single interface, and agents can be summoned in Slack, Teams, Linear or Jira and return draft pull requests.
Cognition acquired Windsurf in July 2025, gaining an agentic IDE that runs alongside Devin.
