DevinWindsurfChoose Devin if you are teams that want to delegate well-scoped engineering tickets end-to-end. Choose Windsurf if you are developers who want an affordable AI editor with agentic capabilities.
In our editorial scoring, Windsurf leads in 3 of six categories (reliability, speed and value), while Devin leads in 2 (output quality and autonomy). On price, Devin runs $20/mo entry + usage (acus) and is proprietary; Windsurf runs free tier / $15-30/mo and is proprietary.
Devin is Cognition's fully autonomous software engineer: give it a task in Slack, Linear, or the web IDE and it plans, writes code, runs tests, and opens a pull request in its own cloud sandbox — including several sessions in parallel. It shines on well-scoped, repetitive engineering work (migrations, test coverage, small features) and improved markedly through its 2.x releases, but it remains weaker on ambiguous, novel tasks, and ACU-based usage pricing means heavy use costs real money. Cognition also acquired Windsurf in 2025, folding its IDE technology into the same product family.
Windsurf (formerly Codeium) is an AI-first code editor featuring Cascade — an agentic flow that can handle multi-file, multi-step coding tasks. It combines the familiarity of VS Code with powerful AI capabilities including code generation, refactoring, and terminal integration.
