Windsurf

Description

Windsurf is the AI IDE originally developed by Codeium and acquired by Cognition AI in December 2025 for ~$250M, with reported ARR of $82M. As of April 2026 it no longer ships under the Codeium brand: it's a Cognition product, the company behind Devin. Its signature feature is Cascade, an agent that understands deep repo context, executes actions, and maintains multi-file consistency. Built as a native IDE on a VS Code fork, it offers supercomplete, chat with memory, and now progressive integration with Devin to delegate long-running tasks. The Pro plan costs $15/mo, $5 less than Cursor, making it its most affordable direct alternative.

Detailed Evaluation

Key strengths

• Cascade, the smoothest contextual agent on the market

  Cascade executes multi-file changes with a visible plan, checkpoints, and rollback, delivering a highly polished experience.

• $5/mo cheaper than Cursor

  Pro at $15/mo with generous usage limits makes it the most attractive alternative on value for money.

• Backed by Cognition AI after the acquisition

  The company behind Devin puts Windsurf at the center of its coding-agent strategy.

• Native IDE with solid performance

  It stays stable and responsive even in large projects, without the occasional sluggishness of some web-based competitors.

• Supercomplete with repo-wide context

  Its autocomplete understands the whole project and suggests edits across multiple files simultaneously.

Limitations to consider

• Rebranding and transition after the acquisition

  Some users report confusion around the Codeium -> Windsurf rebrand and around the upcoming Devin integration.

• Frontier models arrive slightly late

  It tends to integrate new models after Cursor, leaving it one step behind on recent benchmarks.

• Smaller community and ecosystem

  Extensions and learning materials remain scarcer than those of Cursor or Copilot.

Standout Feature

Cascade is the most integrated agentic layer with an IDE UI as of April 2026: it shows plan, diffs, and checkpoints visually, and the upcoming Devin integration will let you delegate long-running tasks outside the editor without leaving the workflow.

Comparison with Alternatives

Versus Cursor it's cheaper and Cascade is more visually polished, but it typically trails by half a step on models and features like Agents Window. Versus Copilot it offers far more agency and multi-file capability.
