Google Antigravity vs Windsurf

True multi-agent architecture with Manager (Mission Control) interface supporting 5+ agents working simultaneously across editor, terminal, and browser. Agents can be assigned different models (Gemini 3.1 Pro, Claude Sonnet 4.6, etc.) within the same mission. Unique artifact trail captures everything agents do for complete auditability.

Cascade provides capable agentic editing with planning and tool calling, but operates primarily as a single-agent experience. The flow-based approach enables multi-step workflows but lacks true parallel multi-agent orchestration comparable to Antigravity's Manager view.

Supports multiple high-quality models including Gemini 3.1 Pro, Claude Sonnet 4.6, and Claude Opus 4.6. However, users report throttling on high-reasoning models and rate limits that refresh every ~5 hours on the free tier. Speed depends on chosen model and current server load.

SWE 1.7 is the headline in-house model on current Devin/Windsurf pricing pages, alongside frontier OpenAI/Claude/Gemini options on Pro. Fast Tab and Cascade remain the daily feel users cite. Exact token/second marketing numbers change; judge latency on your own repo rather than a single blog figure.

Standard VS Code navigation with AI-enhanced search. The built-in Chromium browser enables agents to test and verify web applications directly. AgentKit 2.0 includes domain-specific skills for navigation, but no unique visual code mapping capability.

Codemaps provide AI-annotated visual maps of code structure, grouped sections, nested components, trace guides showing execution paths, and line-level linking. This remains a Windsurf differentiator for large or unfamiliar codebases. Fast Context-style retrieval is part of the product story; verify on your monorepo size.

Agents can work across multiple files, but the experience is distributed across parallel agent workflows rather than focused multi-file refactoring. The artifact trail helps track changes across files, but direct multi-file transformation capabilities are secondary to the multi-agent architecture.

Vibe and Replace enables sophisticated multi-file refactoring across hundreds of files simultaneously. Describe a pattern change and Windsurf applies it everywhere, more capable than find-and-replace, less manual than file-by-file editing. Cascade's flow-based approach naturally handles cross-file dependencies.

Full VS Code compatibility including extension support, themes, and keybindings. The VS Code foundation ensures broad language support and familiar workflows. However, limited to VS Code, no support for JetBrains, Vim, or other editors.

Dual approach: full Cascade experience in the Windsurf Editor plus plugins for 40+ IDEs including JetBrains, Vim, Neovim, Xcode, and VS Code. Teams can maintain consistent AI capabilities across diverse editor preferences, a significant enterprise advantage.

Native Chromium browser integration enables agents to test web applications, capture screenshots, verify UI changes, and perform browser automation without leaving the IDE. This is a unique advantage given Google's browser expertise.

Preview web apps inside the Editor with deployment to Netlify via Cascade. Useful for quick demos and staging deployments, though less thorough than Antigravity's built-in browser agent capabilities.

The Manager (Mission Control) interface introduces new concepts for agent orchestration that require adjustment. Multi-agent workflows have a steeper learning curve compared to traditional AI assistants. The model shift from single-agent chat to parallel agent management takes time to master.

Familiar VS Code-like experience with clear Cascade chat interface. Codemaps provide visual guidance that actually reduces learning curve for new codebases. The flow-based agent interaction is more approachable than Antigravity's parallel agent model.

Free and Pro quotas are real constraints. Google documents refresh behaviour that differs by plan; users on AI Pro have publicly reported hitting weekly ceilings on heavy models and being steered to Ultra or credits. Plan work around quota windows or keep a second tool for crunch weeks.

Free includes a light agent quota plus unlimited Tab. Paid plans advertise daily and weekly usage allowances with extra usage at API pricing when you exceed them. Generally more predictable seat math than Google's multi-product AI bundle, though heavy agent days can still burn through Pro.

Google-scale resources and Gemini distribution. Plan and quota changes can land quickly (I/O 2026 Ultra tier reshuffle is the example). Strong if you already buy Google AI.

Cognition AI ownership after the Windsurf acquisition; product is marketed with Devin. Not the independent Codeium-era story. Strong if you want agent-cloud continuity with Devin.

Beats Cursor on true parallel multi-agent Mission Control. Trails Cursor on general ecosystem maturity and mindshare in many teams.

Competes with Cursor on agentic editing and multi-file refactors; multi-IDE plugins are a Windsurf edge. Cursor often still wins on polish and community defaults.
