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.
The verdict on Windsurf: Developers who want an AI agent that actively works across multiple files, not just suggests the next line Windsurf is not a smarter autocomplete, it's an agent that takes a task description and works across your files and terminal until it's done. Pricing: Rebranded "Devin Desktop" (Cognition, Jun 2026); Free / $20/mo Pro / $80/mo + $40/seat Team / $200/mo Max. Last reviewed: August 2026.
Best For
Developers who want an AI agent that actively works across multiple files, not just suggests the next line
Standout Feature
Cascade operates as a persistent coding agent that plans steps, writes across files, and runs terminal commands
TL;DR
A genuinely capable autonomous agent, still newer software, expect occasional instability on complex tasks.

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.
Our Take
The Cascade agent plans steps, writes across multiple files, and runs commands without waiting for you to guide each move. That makes it meaningfully different from Copilot-style tools for developers doing multi-file refactors or feature builds. The honest tradeoff is maturity: it's newer software and can go off-track on complex tasks. Try it on a contained, well-scoped task before committing it to anything critical.
