The agentic IDE from Cognition (the team behind Devin). Built on a VS Code fork around the Cascade agent, with proprietary SWE-1.5 models, SWE-grep / Fast Context retrieval, Codemaps for visual navigation, and 40+ IDE plugins. Multi-model access to Claude Sonnet 4.6, GPT-5.4, Gemini 3.1 Pro, and Windsurf's own SWE family.

##
+

Pros
- Cascade agent with deep contextual awareness across the full codebase — not just open files
- SWE-1 proprietary model family optimized specifically for software engineering tasks
- Tight terminal and browser integration for true end-to-end task execution
- More affordable than Cursor at comparable feature tiers
- Cascade Flows enable multi-step automated workflows without manual intervention
- Multi-model support — Claude, GPT, Gemini, and the in-house SWE-1 family

##
−

Cons
- Smaller community and extension ecosystem compared to Cursor and VS Code
- Not open source — fully proprietary IDE with no public codebase
- SWE-1 model still catching up to frontier models on the most complex reasoning tasks
- Fewer third-party integrations and MCP server support than Cursor
- Background agents less mature than Cursor's cloud VM-based implementation

Windsurf is the agentic IDE originally built by Codeium and acquired by Cognition — the team behind the Devin autonomous agent — in a roughly $250M deal in late 2025. The combined company is positioning Windsurf as the developer-facing surface while Devin runs in the background, with both products converging toward a single autonomous engineering platform.

Windsurf is built on a VS Code fork and reorganizes the editor around the Cascade agent, which plans multi-step edits, calls tools, and runs terminal commands with deep repository context. Under Cognition, Windsurf added proprietary models — SWE-1.5 reportedly runs ~13× faster than Sonnet 4.5 at near-frontier coding quality — plus SWE-grep / Fast Context, a retrieval system that surfaces relevant code up to 20× faster than embedding-based search, and Codemaps for visual codebase navigation. Premium models include Claude Sonnet 4.6, GPT-5.4, and Gemini 3.1 Pro.

## Key Features

• Cascade: agentic flow that merges chat, planning, and multi-file editing
• SWE-1 / 1.5 / mini: proprietary models tuned for speed and codebase reasoning
• Fast Context (SWE-grep): non-embedding retrieval, up to 20× faster
• Codemaps: AI-generated visual maps of code structure and execution paths
• 40+ IDE plugins: JetBrains, Vim, Neovim, Xcode, and more (Tab + Chat)
• Multi-model: SWE-1.5, Claude Sonnet 4.6, GPT-5.4, Gemini 3.1 Pro
• Memories: long-running learning of project conventions
• Enterprise: SOC 2, SSO, RBAC, BYOK, hybrid deployment

## Version History

Best for Developers who want an AI-native IDE with fast, codebase-aware multi-file edits and broad IDE plugin support

Capability Cascade agent, SWE-1.5 (≈13× faster than Sonnet 4.5), SWE-grep Fast Context, Codemaps, 40+ IDE plugins

Runs on Standalone IDE (VS Code fork) + 40+ IDE plugins (JetBrains, Vim, Neovim, Xcode, …)

Signature Snippet

Copy

```
`Open a Python repo in the Windsurf Editor, ask Cascade: "Add a /webhooks endpoint, update the router, write tests, and document it." Cascade plans the change, edits 5 files in one pass, runs the test suite, and reports back with a diff and the failing-then-passing test output.`
```
