Windsurf
Agentic AI IDE, now owned by Cognition (the Devin team). Cascade handles multi-step tasks across your codebase, with the in-house SWE-1.5 model and cloud sessions for background work.
About Windsurf
Windsurf is an AI-native IDE built around an agent rather than an autocomplete. Its Cascade agent reads the whole codebase, plans, edits across files and runs commands until the task is done. Since Cognition's acquisition, Windsurf also sits alongside Devin, the autonomous software engineer.
What is Windsurf?
Windsurf is an agentic development environment originally built by Codeium. Cognition AI acquired it for $250 million, with the agreement signed in July 2025 and the deal closing in December 2025, bringing Windsurf under the same roof as the Devin autonomous agent team. Since then Cognition has shipped SWE-1.5, Windsurf's proprietary Fast Agent model, which the company claims is roughly 13x faster than Claude Sonnet 4.5; Codemaps for codebase comprehension; and cloud sessions for background development that continue running while you work elsewhere. The commercial trajectory has been steep — Cognition doubled ARR after the acquisition and was reported in April 2026 to be raising at a $25 billion valuation, up from $10.2 billion in September 2025.
Key Features
- Cascade agent: Multi-step autonomous coding with full-codebase awareness and command execution.
- SWE-1.5: Cognition's in-house Fast Agent model, tuned for speed on agentic edits.
- Cloud sessions: Background development runs that continue independently of your local editor.
- Codemaps: Structured maps of a codebase to speed up comprehension and onboarding.
- Quota-based pricing: Daily and weekly quotas replaced the old credit system in March 2026, making spend predictable.
Who Should Use Windsurf?
Windsurf is aimed at engineers who want the agent to do the work rather than assist keystroke by keystroke, and increasingly at enterprise teams — Cognition has captured a segment previously dominated by Cursor and GitHub Copilot. Pro at $20 is the standard individual tier; Max at $200 targets heavy agent users running cloud sessions continuously. Teams at $40 per user adds shared configuration and admin controls. Developers who want a lighter-touch assistant inside a familiar editor may prefer Copilot or Cursor.
Pricing
Windsurf overhauled its pricing on 19 March 2026, retiring the credit-based system in favour of daily and weekly quotas. Pro rose from $15 to $20 per month, and a new Max tier appeared at $200 per month. Teams is $40 per user per month, with Enterprise quoted. A free tier remains available for evaluation. The quota model is a deliberate contrast with Cursor's credit pool: less flexible at the margin, but far easier to predict.
Pros and Cons
| Pros | Cons |
|---|---|
| Cascade is excellent at autonomous multi-step work | Pro rose from $15 to $20 in March 2026 |
| SWE-1.5 is notably fast for agentic edits | Max at $200/month is a steep jump |
| Quota pricing is predictable, unlike credit pools | Roadmap now follows Cognition's enterprise focus |
| Backed by the Devin team and heavy investment | Smaller extension ecosystem than VS Code forks |
Bottom Line
Windsurf has become the enterprise-leaning option among AI IDEs, with real engineering muscle behind it after the Cognition acquisition. Cascade plus SWE-1.5 is a genuinely fast agentic loop, and the quota pricing is easier to budget than Cursor's credits. Try Pro at $20 against Cursor Pro at the same price — the choice mostly comes down to whether you prefer an agent-first workflow or an editor-first one.
