Cursor

AI IDE · by Anysphere · official site

What it actually does

Cursor is a fork of VS Code with deep AI integration at the editor level. It wraps multiple LLMs—Claude, GPT‑4o, and a proprietary fast model—into a single UI that can generate, edit, and refactor code across your project. Unlike a chat plugin, Cursor replaces the editor's core: you can invoke AI on a selection, ask it to modify files, or give it a multi-step agent task (e.g., “add an endpoint with tests and a migration”). The agent can read files, run terminal commands, and iterate on errors. Context is pulled from open tabs, your selected files, or the whole project index (embeddings-based). By 2026, Cursor supports real-time collaboration, custom rules per project, and a CLI-based “Cursor Server” for headless batch operations.

Who it's for

Full-time developers, small teams, and solo founders who spend most of their day writing code and want AI to handle boilerplate, refactors, and debugging without leaving the editor. It’s for people who already live in VS Code and want a drop-in replacement that amplifies their existing workflow—not for non-programmers or those who need a completely hands-off “build my app” tool.

What works

Inline edits with context awareness. The agent understands your open files and recent changes. Asking “refactor this function to use async” rarely breaks unrelated code because it scans imports and usage patterns across the project.
Multi-file agent loops. You can say “create a React component, a Storybook story, and a test file” and it will generate all three, run npm test, fix failures, and report back. In 2026, the agent can handle 20+ file changes in one pass with surprisingly low hallucination rate for common frameworks.
Tab completion cribbed from Copilot, but faster. Cursor’s fast model provides latency under 200ms for single-line completions. I’ve seen it beat Copilot’s inline suggestions on boilerplate-heavy languages (Django, Rails).
Custom rules and documentation indexing. You can drop a markdown file into .cursor/rules and the agent will consistently follow your conventions (e.g., “use early returns, never else”). It also indexes your internal docs and pulls them as context for questions.
Terminal integration. The agent can run shell commands and see output. This makes it useful for debugging build errors or orchestrating scripts—something Copilot’s chat struggles with.

What breaks

Context budget management is manual. The agent often includes irrelevant files and misses critical ones, especially in monorepos with 50+ packages. You must manually “@” mention the right files unless you set up an index, which takes time to configure.
Large refactors still lie. If you ask to rename a function across 40 files, it may miss 2–3 or change unrelated occurrences. The model’s project awareness is not yet a real static analysis engine.
No offline mode. Cursor requires a persistent internet connection. All AI calls go to their servers; local models are not supported (as of mid-2026). This is a blocker for air-gapped workflows.
Bleeding edge stability. Because Cursor is a fork of VS Code, updates sometimes lag behind VS Code’s extensions or cause breakages. I’ve lost a custom keybinding twice after a Cursor update.
Pricing scales with usage, not value. The Pro plan caps fast requests but unlimited slow requests. Heavy users hit the cap mid-month and experience degraded latency, forcing manual work while you wait for the quota to reset.

Pricing reality

Cursor Pro is $20/month for an individual (2026 pricing unchanged). Business plan is $40/user/month with admin controls and priority support. Both include 500 fast premium requests per month; additional fast requests cost $0.01 each. Slower (GPT-4o) requests are unlimited but slower by 2–3 seconds per turn. Teams using agent loops heavily can burn through 500 fast requests in a week. Enterprise plans vary. No free tier for AI features beyond a 14-day trial. For comparison, Copilot Pro is $10/month, Claude Code is $20/month (via Anthropic API), and Zed’s AI features are included in its $12/month subscription.

The honest comparison

vs Claude Code (CLI agent): Claude Code is better for headless automation—run in CI, pipe stdin, script batch refactors. It’s faster for one-shot file manipulation. Cursor wins for interactive development: inline editing, tab completions, and visual debugging. If you work primarily in a terminal, pick Claude Code. If you want an IDE, pick Cursor. vs GitHub Copilot (VS Code extension): Copilot is cheaper ($10 vs $20), has better model availability via custom models, and its inline suggestions are marginally more accurate for Java/TypeScript. Cursor’s agent is far more capable for multi-step tasks and cross-file changes. Copilot’s chat still feels bolted on; Cursor feels native. If you rarely need agentic multi-file edits, save money with Copilot. vs Zed (editor with AI): Zed is faster (native port, Rust-based) and has excellent AI inline completions with low latency. But its agent capabilities are embryonic—multi-file editing and project awareness still beta as of 2026. Cursor is more mature for anything beyond single-file suggestions. If you value editor speed and don’t need an agent, Zed is compelling. If you need a reliable agent, stick with Cursor.

When to use it

Use Cursor when your daily work involves multi-file agent tasks, custom conventions, and you want a drop-in VS Code replacement with deep AI integration—but only if you can tolerate the ongoing cost of fast request quotas and the occasional instability of a fork.
