Cursor AI Review (2026): SpaceX Owns It, OpenAI Leaves

This Cursor AI review starts with a date: 14 August 2026. On that day SpaceX closed its 60 billion dollar, all-stock purchase of Anysphere, the company behind Cursor. As a result, the most popular AI code editor now sits inside Elon Musk’s AI division.

Two weeks later, OpenAI said it would pull its models from the product. Meanwhile, the pricing page gained Grok limits, a Grok Bot and a second usage pool. So older write-ups describe a different tool.

Therefore the testing behind this Cursor AI review followed three questions. First, what does Cursor do today? Second, what does each plan really buy? Finally, should you still build your workflow on it?

So, what is Cursor AI? It is a code editor with an AI agent at its center. The desktop app is a fork of VS Code, so your extensions, themes and shortcuts carry over. However, the AI is not a side panel. It reads the whole repository and edits it.

The company now describes Cursor as a coding agent for building ambitious software. In practice, that means four surfaces: the desktop editor, a command line tool, cloud agents and a web view. In addition, Bugbot reviews pull requests on GitHub.

Anysphere launched the editor in 2023 and it grew fast. For example, annual recurring revenue passed 2 billion dollars by February 2026, according to reports on the deal. Today the company says more than half of the Fortune 500 use it.

Cursor suits working developers first. If you already ship code in VS Code, the switch takes minutes, and the agent pays off on real repositories. Similarly, teams get shared rules, admin billing and a privacy mode.

On the other hand, it is not built for complete beginners. You still need to read a diff and judge a plan. For that reason, non-coders usually do better with an app builder that hosts the result for them.

Cursor works as one agent across several surfaces. First, it indexes your codebase. Then you describe a task, pick a model and review the changes it proposes. Below are the four parts that shape daily use.

Agent mode is the core of the product. You type a goal in plain English, and Cursor plans the work, edits several files and runs terminal commands. After that, it reads the errors and tries again.

You stay in control through diffs. Each change shows up for review, so you accept, reject or redirect it. In addition, rules, skills, hooks and MCP servers let you shape how the agent behaves in your project.

Tab is the feature most users meet first. It predicts the next edit, not just the next word, and it often jumps to the next place you need to change. Consequently, small refactors feel like pressing one key.

Tab completions are unlimited on Pro, Pro Plus and Ultra. Because of this, light users rarely touch their usage pool at all.

Cloud Agents run in the background on remote machines. They work in parallel, for hours or days, and open pull requests when they finish. Since 27 August 2026 they can even start without a GitHub repository.

Furthermore, Cursor Projects arrived on 10 September 2026. A coordinator agent splits a large goal across subagents. Meanwhile, the Cursor CLI brings the same agent to any terminal, which puts it in direct competition with Claude Code.

Bugbot reviews pull requests and flags likely bugs, billed on usage. In addition, the 23 September 2026 release added Rollouts, which watches each deploy, and Security Review, which hunts exploitable bugs.

Grok Bot is the newest piece. Cursor calls it an AI teammate that can sign in to your tools, including Slack. However, it is also the clearest sign of the new owner, and Enterprise plans add audit controls for it.

In daily work, Cursor is still the editor to beat. Reviewers keep praising its codebase awareness, and agent mode handles multi-file changes that simpler assistants drop. For instance, one September 2026 comparison found it resolved tasks about 30 percent faster than GitHub Copilot.

Accuracy is less clear. That same comparison put Copilot Pro ahead on tasks solved, 56 percent against 51.7 percent. Moreover, the agent can still break working code on large, sprawling repositories, so you need tests and a careful eye.

The weakest point this Cursor AI review found is trust around billing. Cursor scores 1.5 out of 5 on Trustpilot from 337 reviews, and 79 percent of them give one star. Most complaints describe surprise on-demand charges, hard cancellations and slow support. Developers who love the editor rarely post there, so read that score as a billing warning, not a verdict on the code.

Every price in this Cursor AI review comes from the official pricing page and docs as they stood on 5 October 2026. All figures are monthly, in US dollars, before tax.

So is Cursor AI free? Yes, in a limited way. The Hobby plan needs no card and includes a small number of Agent requests plus access to Composer. However, serious work starts at Pro. Paid plans now carry two usage pools that reset each month. The first covers Cursor’s own models, Grok and Composer 2.5, with far more included usage. The second covers third-party models such as Claude and Gemini, charged at API rates. As a result, your model choice decides how fast the plan drains. When a pool runs out, you either upgrade or switch on on-demand usage at the same rates. Therefore, set a spending limit before you start a long agent run.

Cursor’s owner is now SpaceX. The company agreed to buy Anysphere on 16 June 2026 and closed the deal on 14 August 2026. Because xAI had merged into SpaceX earlier in the year, Cursor now works alongside the Grok team.

The upside is compute. Cursor says it gains access to the world’s largest GPU fleet, and it already helped train Grok 4.5 and Grok 4.6. Consequently, Grok usage inside the editor is cheap and generous.

The downside is model choice. On 29 August 2026, OpenAI said it will pull its models from Cursor on 12 November 2026. It also said future models will not arrive there. Claude and Gemini remain on the model list today. Still, a neutral editor that offered every lab’s best model was the original pitch, and that promise is now weaker.

Yes, Cursor is legitimate. It is a real product with millions of users, enterprise customers such as NVIDIA and Stripe on its homepage, and one of the largest acquisitions in startup history behind it. In addition, Teams plans include SAML single sign-on and a team-wide privacy mode.

The caveats are practical. First, on-demand usage can produce bills you did not plan. Second, support leans on chatbots, according to many user reports. Finally, the ownership change may worry companies with strict vendor rules.

In short, Cursor is safe to use as software. However, turn on privacy mode for client code, cap your spending and keep your invoices.

Claude Code is Anthropic’s terminal agent and the rival developers mention most. It reads a repository, plans the change and runs the tests itself.

Choose it when you live in the terminal and want Anthropic’s models first. In contrast, Cursor wins when you want a full editor with visual diffs.

GitHub Copilot is the cheaper, safer default for many teams. It works inside VS Code, JetBrains and Visual Studio, so nobody has to change editors.

Therefore it fits companies already on GitHub. Cursor remains faster and deeper on multi-file agent work.

Replit moves the whole loop into a browser tab. Its agent writes the app, the workspace runs it and one click publishes it.

As a result, beginners reach a live product sooner than they would in a local editor. Developers with an existing codebase will still prefer Cursor.

Lovable builds full web apps from a chat prompt, with a database, logins and hosting included. Our Lovable review covers the credit math.

Consequently it suits founders more than engineers. The advice this Cursor AI review gives non-coders is simple: start there, not in a code editor.

Pros

• Agent mode plans, edits many files and runs commands on its own
• Unlimited Tab completion on every paid plan
• Built on VS Code, so extensions and shortcuts carry over
• Cloud Agents and Projects run long tasks in parallel
• Generous Grok and Composer usage in a separate pool
• Free Hobby plan with no credit card

Cons

• OpenAI models leave the editor on 12 November 2026
• Third-party models drain a plan quickly at API rates
• Trustpilot score of 1.5 from 337 reviews, mostly about billing
• On-demand usage can cause surprise charges
• No JetBrains or Visual Studio version of the editor
• No public affiliate program and only a limited referral scheme

Cursor is still the most capable AI code editor you can install today. The agent is fast, Tab is excellent, and the release pace since the acquisition has been relentless. For a working developer, 20 dollars a month remains easy to justify.

However, here is the short answer from this Cursor AI review. Buy Pro if you are happy with Grok, Composer, Claude and Gemini. Think twice if your team depends on OpenAI models or on a neutral vendor. And set a spending cap on day one.

Ultimately, Cursor won by letting developers pick any model inside one great editor. Now it belongs to a company that builds one of those models. The editor is as good as ever. The open question is how long the choice lasts.
