Windsurf
An agentic coding IDE pairing an editor with autonomous coding agents — renamed Devin Desktop after Cognition AI's acquisition, keeping the same editor and Claude/GPT/Gemini model choice.

Overview
Windsurf is an AI-first code editor built by Codeium that introduces the concept of 'agentic flows', where the AI doesn't just suggest code but actively participates in multi-step engineering tasks alongside you. Its signature feature, Cascade, operates as a persistent AI coding agent that can read your codebase, plan implementation steps, write across multiple files, run terminal commands, observe the results, and iterate, without you manually directing each step. This is a meaningful step beyond autocomplete: describe a feature in plain language and Cascade implements it, handles edge cases, and runs tests to verify the result.
Windsurf inherits Codeium's editor foundation (VS Code-compatible) so your existing extensions, keybindings, and themes carry over. The free tier provides limited Cascade interactions per month. Pro plans start at $15/month for expanded agent usage.
Windsurf sits in the same category as Cursor but emphasizes agent autonomy over conversational back-and-forth, better suited to developers who want to define goals and review outputs rather than micromanage implementation steps.
