Both are AI-first code editors built on VS Code. The differences are in the model, context strategy, and pricing. Here's what actually matters for your workflow.
Name change: Windsurf is now called Devin Desktop (see the vendor’s announcement). This page keeps the Windsurf name people search for; plans and features change often, so check each vendor’s own pages before you buy.

If you only have 30 seconds: Windsurf wins on out-of-the-box agentic flow and price. Cursor wins on model choice, context depth, and MCP integrations. Claude Code is in a different category entirely.

Windsurf was built from the ground up for agentic coding. Cognition, the company behind Devin, now runs it: on 2026-06-02 it was renamed Devin Desktop, and its local agent Cascade was replaced by Devin Local (see the Devin Desktop FAQ).
The standout feature. The agent autonomously writes multi-file changes, runs terminal commands, reads error messages, and fixes issues in a continuous loop — without you needing to guide each step. It reads your intent and executes.
Use case: "Refactor this module to use async/await throughout" — the agent handles the whole thing, including test files.
Windsurf's proprietary model trained specifically on software engineering tasks.
This is Windsurf's moat: a specialized model, not a general-purpose LLM bolted onto an IDE.
Windsurf's context file equivalent to .cursorrules. Lives in your project root. Tell it your stack, coding conventions, what to never do, and domain-specific patterns. Devin Desktop still reads .windsurfrules, prefers .devin/rules/, and also reads AGENTS.md.
The two gaps that matter: less model choice than Cursor, and no MCP support means you can't connect Windsurf to databases, browser automation, or external APIs the way Cursor + MCP allows.
Cursor (by Anysphere) took a different bet: give developers the freedom to choose their model, maximize context depth, and build a full ecosystem around the IDE. It's the most customizable AI code editor available.
Cursor's multi-file generation tool. Unlike a single-file edit, Composer shows you a full diff of every file it wants to change before applying. You review, adjust, and approve — making it more surgical than the Devin Desktop agent but less autonomous.
Agent mode adds autonomy: Composer can run terminal commands and iterate, similar to the Devin Desktop agent.
Switch freely between Claude, OpenAI and Gemini models, or bring your own API key. This is Cursor's superpower — you're not locked to one provider's capabilities or pricing.
When a new Claude model or a better model ships, Cursor users get it immediately. Devin Desktop users wait for the vendor to integrate it.
Cursor supports MCP (Model Context Protocol) servers natively. This means Claude inside Cursor can connect to your database, control a browser via Playwright, query APIs, and read real-time data — capabilities that go far beyond what .cursorrules alone enables.
Cursor's extended context mode gives the AI more codebase awareness, up to the limit of the model you choose. On large monorepos, this translates to understanding cross-module dependencies, catching subtle regressions, and refactoring across many files with precision.
Every major AI code editor has a rules file that tells the AI about your project. The format is similar — the differences are in nesting, depth, and how each tool loads them.
| Windsurf | Cursor | Claude Code | |
|---|---|---|---|
| Context File | .windsurfrules | .cursorrules | CLAUDE.md |
| Location | Project root | Project root | Project root (+ any subdirectory) |
| Nested Files | No | No | Yes — CLAUDE.md per directory |
| Format | Markdown | Markdown | Markdown |
| Auto-loaded | Yes | Yes | Yes |
| Brainfile Supports | ✅ Yes | ✅ Yes | ✅ Yes |
The honest answer depends less on which editor is "better" and more on what you're actually building every day.
The Devin Desktop agent is built for autonomous multi-file generation. Tell it "create a full CRUD module for users with TypeScript, Zod validation, and Prisma" — the agent executes the entire thing autonomously.
Model flexibility is Cursor's superpower. Switch between Claude, OpenAI and Gemini models per task, or bring your own API key. Windsurf locks you to their model stack.
Both editors connect to MCP servers, so a database, browser automation or an external API can be reached from inside either one. Pick on the rest of your workflow, and check each vendor’s MCP docs for the current limits.
For maximum autonomous capability on complex multi-step tasks, Claude Code (terminal-native, no IDE) outperforms both Windsurf and Cursor. It runs shell commands, iterates on failures, and uses CLAUDE.md for deep project context.
Whether you're using .windsurfrules or .cursorrules, you're dealing with the same unsolved problem: writing context files that actually work requires expertise most developers don't have time for.
Generic rules don't work. Most developers write rules like "use TypeScript" and "follow best practices." These are useless — the AI already knows this. What actually moves the needle is domain-specific context: your architecture decisions, your team's conventions, what NOT to do and why.
Rules go stale within weeks. Your stack evolves, your conventions change, new patterns emerge. Nobody maintains .windsurfrules or .cursorrules once they're written. Within a month, the AI is working from outdated context.
You'd need to maintain two separate files if you switch tools. .windsurfrules and .cursorrules are different files. If you use both editors (or your team uses different ones), you're maintaining duplicates that drift apart.
Brainfile is built for Claude Code, not Windsurf or Cursor. It ships no .windsurfrules or .cursorrules files; the rules guidance on this page is yours to apply in either editor.
Stop writing generic instructions the AI ignores. Brainfile gives Claude Code a structure built from the system we run our own businesses on.
