Cursor AI: A Month of Real Usage Review

I've been using Cursor as my primary IDE for a month. Here's the honest review — the good, the great, and the occasional frustrating.

The Setup

Hardware: 16GB RAM laptop
Project: Full-stack TypeScript (Next.js + Node.js)
Models used: Claude 3.5 Sonnet (primarily), GPT-4o (occasionally)
Feature usage: Cmd+K, Composer, Chat, Tab completion

What Genuinely Changed My Workflow

Tab Completion That Thinks Ahead

This is not autocomplete. It's different. Cursor predicts entire logical blocks:

// I type: "const handleSubmit = async (e: React.FormEvent) => {"
// Cursor completes:
const handleSubmit = async (e: React.FormEvent) => {
  e.preventDefault();
  setLoading(true);
  try {
    await createPost({ title, content });
    router.push('/dashboard');
  } catch (error) {
    setError('Failed to create post. Please try again.');
  } finally {
    setLoading(false);
  }
};

It predicted the try/catch pattern, the specific functions from context, and the loading state pattern. This is 10x better than GitHub Copilot's single-line suggestions.

Composer for Multi-File Changes

Task: "Add pagination to the posts list, backend and frontend"

Cursor Composer:

1. Reads the existing posts route
2. Reads the posts list component
3. Modifies the API to accept page and limit params
4. Updates the database query
5. Adds pagination UI to the component
6. Updates the TypeScript types

All in one flow. Coherent. Actually works. This is where the ROI is undeniable.

Codebase Q&A

Me: "How does authentication work in this project?"
Cursor: *reads auth files, middleware, JWT utils*
"Your auth uses JWT stored in httpOnly cookies. 
The middleware in auth.ts validates the token on protected routes.
The token is refreshed in..."

Onboarding to a new codebase with Cursor is 3x faster.

The Frustrations

1. Context window limitations — On very large codebases, it loses track of distant files
2. Hallucinating APIs — Occasionally invents method names. Always verify.
3. Slow on complex Composer tasks — 30-60 seconds for big multi-file operations
4. Monthly request limits on Pro — Heavy users hit the cap

The Verdict

At $20/month, Cursor is the best value in developer tooling I've ever paid for. The Composer feature alone saves me 1-2 hours per week. Tab completion makes me measurably faster.

The bugs and limitations are real but the productivity gains outweigh them significantly.
