Cursor How-To 2026: The AI Code Editor - Agent Mode, Composer, and Pricing
Cursor is a VS Code-based AI code editor. Composer edits many files at once, and Agent mode plans, writes code, runs tests, and fixes errors on its own. Plus Tab completion, codebase-aware AI, and MCP support. Here's how to access and use it, the Free / Pro $20 pricing, and the limits.
Ask developers “what do you code in these days?” and Cursor comes up a lot. The short version: the AI edits multiple files at once and even runs tests to fix its own errors. It’s well past autocomplete, and if you’re comfortable in VS Code, it’s worth a try right now.
What is Cursor?
It’s a development tool with AI embedded deep in the editor. Built as a fork of VS Code, it keeps the familiar interface, keybindings, and extension marketplace while adding an AI layer at the core - so VS Code users need almost no ramp-up. The point is that it goes past autocomplete: it understands your whole project context, edits multiple files at once, and, when asked, runs tests and fixes errors.
- Tab completion - predicts your next edit from recent changes
- Composer - edit many files at once (great for large refactors)
- Agent mode - plan, write code, run tests, and auto-fix errors
- Codebase-aware AI, MCP support, in-editor PR review
- Privacy mode - option where code isn’t stored or used for training
Why it’s worth it
The win is removing repetition - refactors and boilerplate get much faster. Attaching tools to a chat workflow connects to GitHub MCP and Playwright MCP, and the skills/MCP concepts sit alongside Skills vs MCP.
How to start
Download from cursor.com and install. It looks just like VS Code, so you can start immediately.
- Open a project - open your existing code folder as-is
- Edit by Tab or chat - take completions, or ask “fix this part” in chat
- Big jobs with Composer/Agent - multi-file edits, feature work, and tests at once
You can also bring your own OpenAI or Anthropic API keys. Results and cost vary with the model you run (Claude, GPT, Gemini).
Pricing and limits
| Plan | Price | Notes |
|---|---|---|
| Hobby | Free | Fine for 2-4 hours of coding a day |
| Pro | $20/mo | For regular developers |
| Pro+ | $60/mo | Heavier usage |
| Ultra | $200/mo | Power users (20x Pro’s credits) |
Teams are $40/user/mo. One caveat: billing is credit- (usage-) based, so running lots of heavy Agent jobs can make your actual bill higher than the plan price. And AI-written code can contain plausible-looking errors, so a human must always review and test it.
Frequently Asked Questions
Q. Is Cursor free? The Hobby plan is free and fine for 2-4 hours of coding a day. Serious use needs Pro ($20/mo) or higher, and billing is credit- (usage-) based.
Q. How is it different from VS Code? Cursor is built on VS Code - so interface, keybindings, and extensions are compatible - with codebase-aware AI (Composer, Agent mode) added at the core.
Q. Which AI models does it use? You can pick current frontier models like Claude 4.x, GPT, and Gemini, and you can connect your own OpenAI or Anthropic API keys.
