Our Take on Windsurf (by Cognition)
“Windsurf under Cognition has become a serious Cursor rival with proprietary speed (SWE-1.5), Codemaps for visual navigation, and 40+ IDE coverage. Best for teams that need multi-IDE flexibility and fast inference.”
Strengths
- SWE-1.5 proprietary model is dramatically faster than frontier alternatives
- Fast Context retrieves code 10× faster than standard agentic search
- Codemaps provide AI-annotated visual navigation of complex codebases
- 40+ IDE plugins — not locked to a single editor like Cursor
- Vibe and Replace handles massive multi-file refactoring
- Cascade agentic flow is among the best for multi-step coding
Limitations
- Cascade credits can run out quickly on complex projects
- Full agentic experience only in Windsurf Editor, not all plugins
- Cognition acquisition means product direction may evolve

Cognition's Windsurf is the anti vibe code IDE tool. It is actually genius they are creating features meant to help engineers think and plan instead of adding AI features to improve agents to code better. At the end of the day, good products are a result of the minds behind…
Introducing Codemaps in @windsurf! powered by SWE-1.5 and Sonnet 4.5 “Your code is your understanding of the problem you’re exploring. So it’s only when you have your code in your head that you really understand the problem.” — @paulg
holy moly @windsurf_ai from @codeiumdev is the best AI coding agent experience i've had 💨 🏄♂️ I scaffolded an entire Next.js app, including frontend and backend - db, auth, frontend framework etc. by simply talking to "Cascade" their AI coding agent they've figured something…
The entire AI coding industry just got exposed. Someone leaked the system architecture of AI coding tools: Cursor, Devin AI, Windsurf, Claude Code, v0, Lovable, Replit, 30,000+ lines of hidden instructions.
A skill for AI-powered coding agents (Claude Code, Cursor, Windsurf, etc.) that generates production-ready App Store screenshots for iOS apps. Scaffolds a Next.js project and exports at all required Apple resolutions.
The system prompts of every major AI coding assistant just got leaked. Cursor. Claude Code. Windsurf. Devin. Replit. v0. 30,000+ lines of internal instructions. This is the Rosetta Stone of AI agents.
