Cursor and Windsurf both offer AI-powered coding in a VS Code fork, but their behavior differs enough to matter for React development. This comparison focuses on the specific workflows React engineers care about: component generation, custom hook creation, refactoring JSX, multi-file state management changes, and TypeScript type inference.

Editor Setup

Both editors require minimal configuration for a React/TypeScript project.

Cursor setup: Install Cursor, create .cursorrules in project root, use Cmd+K for inline edits, Cmd+L for chat.

Windsurf setup: Install Windsurf, uses “Cascade” for multi-step AI flows, Cmd+I for inline, Cmd+L for chat panel.

# .cursorrules (Cursor)
You are working in a React 19 + TypeScript 5 + Vite project.
- All components use function components with TypeScript
- State management: Zustand for global, useState/useReducer for local
- Styling: Tailwind CSS with cn() utility from clsx
- Import order: React -> external libraries -> internal components -> types

Component Generation

Test prompt: “Create a DataTable component that accepts typed columns and row data, supports sorting, and shows a loading skeleton”

Cursor output (Cmd+K inline):

Generated a complete component with generic typing, useMemo for sorted rows, and Tailwind classes.

interface Column<T> {
  key: keyof T;
  header: string;
  sortable?: boolean;
  render?: (value: T[keyof T], row: T) => React.ReactNode;
}

interface DataTableProps<T extends object> {
  columns: Column<T>[];
  data: T[];
  isLoading?: boolean;
  defaultSortKey?: keyof T;
}

function DataTable<T extends object>({
  columns,
  data,
  isLoading = false,
  defaultSortKey,
}: DataTableProps<T>) {
  const [sortKey, setSortKey] = useState<keyof T | null>(defaultSortKey ?? null);
  const [sortDirection, setSortDirection] = useState<"asc" | "desc">("asc");

  const sortedData = useMemo(() => {
    if (!sortKey) return data;
    return [...data].sort((a, b) => {
      const aVal = a[sortKey];
      const bVal = b[sortKey];
      const comparison = aVal < bVal ? -1 : aVal > bVal ? 1 : 0;
      return sortDirection === "asc" ? comparison : -comparison;
    });
  }, [data, sortKey, sortDirection]);
}

Cursor’s first-pass output required zero follow-up prompts.

Windsurf output: Similar component but did not automatically add the render prop to Column (required a follow-up) and used a hardcoded number of rows for the loading skeleton instead of inferring from data length. One follow-up prompt needed.

Custom Hook Generation

Test prompt: “Write a useIntersectionObserver hook that accepts a callback and options, cleans up on unmount, and handles SSR”

// Cursor output — all concerns addressed in one pass
function useIntersectionObserver(
  callback: IntersectionObserverCallback,
  options?: IntersectionObserverInit
): (node: Element | null) => void {
  const observerRef = useRef<IntersectionObserver | null>(null);
  const callbackRef = useRef(callback);

  useEffect(() => {
    callbackRef.current = callback;
  });

  return useCallback((node: Element | null) => {
    if (typeof window === "undefined") return; // SSR guard

    if (observerRef.current) {
      observerRef.current.disconnect();
    }

    if (!node) return;

    observerRef.current = new IntersectionObserver(
      (entries, observer) => callbackRef.current(entries, observer),
      options
    );

    observerRef.current.observe(node);
  }, []);
}

Cursor included the callbackRef pattern (avoids stale closure), SSR guard, and proper cleanup. Windsurf’s hook used useEffect directly on a ref, which requires the component to pass an existing element ref rather than returning a callback ref — valid but less flexible.

Multi-File Refactoring: Adding React Query

Task: “Migrate these 3 components from manual fetch/useState to React Query. Keep the existing API calls.”

This is where Cascade (Windsurf) shows its advantage.

Windsurf Cascade behavior:

1. Read all 3 component files
2. Read existing API utility files
3. Generated a queryKeys constant file
4. Modified each component to use useQuery
5. Added React Query provider to App.tsx
6. Showed a diff summary of all changes before applying

Cursor Composer behavior:

1. Read all 3 component files when explicitly @mentioned
2. Generated the queryKeys file and component changes
3. Did not automatically update App.tsx (missed the provider addition)
4. Required a follow-up prompt to add the provider

For a migration task affecting multiple files, Windsurf’s Cascade was more thorough in the initial pass.

TypeScript Integration

Both editors have strong TypeScript awareness. The differences:

Cursor is better at following your existing type patterns. If you have an ApiResponse<T> wrapper type used across the codebase, Cursor picks it up from context and uses it consistently.

Windsurf has stronger inference for JSX-heavy refactors. When restructuring a component tree, it better tracks which props flow through which components and updates intermediate types.

Autocomplete Quality for React Patterns

Tested on 50 React-specific completions:

Pricing (March 2026)

Windsurf is $5/mo cheaper at the Pro tier.

Performance Metrics

Both editors deliver real-time completions. Testing on a 200-file React codebase:

Cursor is marginally faster on single-file edits. Windsurf’s multi-file indexing is quicker, but both tools feel responsive in practice. If you have <16GB RAM, neither adds noticeable drag.

IDE Feature Comparison

Cursor’s .cursorrules file is shareable across a team — Windsurf requires instructions entered in the UI or in a project settings file. For teams enforcing consistent AI behavior, Cursor has the edge.

Testing on Real React Tasks

Task 1: State Management Migration

Migrated a 5-component local useState tree to Zustand.

• Cursor: Generated correct Zustand store, updated all 5 components correctly. One prompt.
• Windsurf: Generated correct store but missed updating two nested component imports. Required manual fix.

Task 2: Adding React Query to Existing Fetch Code

Converted 3 fetch-based API calls to React Query with 20 lines of existing hooks.

• Cursor: Composer mode handled all 3 files, but didn’t add the QueryClientProvider to App.tsx (required a second prompt).
• Windsurf: Cascade mode included the provider, suggested better key structure, more complete on first pass.

Task 3: TypeScript Type Refactor

Widened a union type (4 variants) and updated consuming code.

• Cursor: Changed the type correctly, auto-updated 8 of 9 consuming functions. Missed one optional property.
• Windsurf: Updated all 9 functions correctly, better at tracking optional vs required fields.

CLI Installation

Cursor:

# Download from https://www.cursor.com/
# Once installed, configure from Settings > Cursor Settings

# Set API key for Claude models
# Settings > API keys > Enter Claude API key

# Create .cursorrules file in repo root
echo "You are a React expert. Use React 19, TypeScript, Tailwind, and Zustand." > .cursorrules

Windsurf:

# Download from https://windsurf.dev/
# Install and open project directory

# Configure instructions in Settings > AI > System Instructions
# Or create a project instructions file and reference it in settings

Neither tool requires terminal installation or CLI setup — both are desktop applications. Configuration happens in-editor.

Strength Summary

Cursor strengths:

• Faster single-file inline edits
• .cursorrules shareable across teams
• Better TypeScript pattern recognition from existing code
• Slightly more predictable on boilerplate generation

Windsurf strengths:

• Multi-file refactors complete on first pass more often
• Cascade flow is visually clearer for complex tasks
• Slightly lower cost
• Better at tracking data flow through component trees

Which to Choose for React

Choose Cursor if:

• Your React work is mostly single-component edits and inline fixes
• You want the most consistent TypeScript type usage from existing patterns
• You use .cursorrules for team-wide AI behavior standardization

Choose Windsurf if:

• You frequently do multi-file refactors (adding a library, restructuring state)
• You value Cascade’s end-to-end multi-file awareness
• You prefer a slightly lower monthly cost

Both tools beat a standard Copilot + VS Code setup for React development.
