Cursor

Cursor is an AI-first code editor built on VS Code that puts large language models directly inside your development environment rather than bolted on as a plugin. You get the familiar VS Code interface, your existing extensions, and your muscle memory, plus an AI layer that understands your entire codebase and can write, edit, test, and debug code autonomously.

The product was built by Anysphere, a San Francisco company founded in 2022 by four MIT students. It grew from an $8 million seed round to a $29.3 billion valuation by late 2025, with Google and NVIDIA among its investors and Jensen Huang publicly calling it his favorite enterprise AI service. Over half the Fortune 500 now uses Cursor. That's not a marketing number you can fake.

The tab completion is the thing most developers talk about first. It doesn't just finish the current line; it predicts the next several lines based on what you're doing and what's in your codebase, and it's right with surprising frequency. Beyond tab completion, the Agent mode lets you hand off multi-step tasks entirely. You describe what you want built, and Cursor plans the work, writes the files, runs tests, and iterates. An "autonomy slider" controls how much oversight you want to maintain, from reviewing every change to letting the agent run until it's done. Background agents work on tasks while you're doing something else entirely.

Cursor supports OpenAI, Anthropic Claude, Gemini, and xAI models interchangeably, so you're not locked into one provider's capabilities. Codebase indexing means the AI can reason about your entire project rather than just the file you have open, which matters once your project grows beyond a few hundred lines.

Honest friction points exist. In June 2025, Anysphere shifted from 500 fixed fast responses per month to usage-based credits, effectively cutting the usable request volume for many Pro users and generating significant backlash. Privacy requires deliberate action: by default, your code and prompts may be used to train models and shared with third-party model providers. Enabling Privacy Mode opts you out, but it's not on by default. The company also had a visible stumble in April 2025 when an AI support bot incorrectly told users they needed separate subscriptions for each device, which required a public retraction.

The pricing ladder is steep at the upper end. The Pro plan at $20 a month covers most developers. Heavy agent users will find themselves bumping against limits and eyeing the $60 Pro+ or $200 Ultra tiers. BugBot, the PR review tool, is priced separately.

For developers who write code daily and work in any mainstream language, Cursor is the most mature AI coding environment available. The ecosystem is deep, the codebase awareness is real, and the productivity gains are measurable.

Cursor: Pros & Cons

| Pros (The Wins) | Cons (The Friction) |

| :--- | :--- |

| Tab Completion: Predicts multiple lines ahead with high accuracy. | Pricing Changes: June 2025 shift cut effective requests; users felt blindsided. |

| Agent Mode: Plans and executes multi-step tasks end-to-end autonomously. | Privacy Default: Code used for training unless Privacy Mode manually enabled. |

| Codebase Context: Indexes your full project for AI that understands the whole repo. | Cost Ceiling: Heavy users face $60 or $200/mo to avoid hitting limits. |

| Model Flexibility: Switch between Claude, GPT-4, Gemini, and xAI models freely. | Keyboard Conflicts: Overrides familiar shortcuts like Cmd+K in the terminal. |

| VS Code Compatible: Keeps your existing extensions, themes, and workflows intact. | Performance: Can feel sluggish on very large files or complex repos. |
