Cursor vs Windsurf: How to Pick an AI Code Editor in 2026

Cursor and Windsurf are the two names that come up first when a builder picks an AI code editor in 2026. Both started as forks of Visual Studio Code, both put a capable agent inside the editor, and both have spent the last year being fought over by some of the largest companies in tech. This guide cuts past the marketing: what each one is genuinely good at, what it costs, who owns it now, and which to choose for the work you actually do.

No declared winner here. The honest answer is that they are close, they overlap, and the right pick depends on how you like to work. We will give you a framework, not a verdict.

What Cursor and Windsurf actually are

Start with the thing the marketing pages bury: both editors are forks of Visual Studio Code. They open to a familiar layout, run most of your existing VS Code extensions, and read your settings. You are not learning a new editor from scratch with either one. What changes is what they build on top of that base, and that is where they diverge.

Cursor, made by a company called Anysphere, is an editor that puts AI at the center of normal coding. You type and a fast model finishes your lines; you open a chat and it edits across files; you hand a task to an agent and it works. It runs the major frontier models alongside its own in-house coding model, Composer. By early 2026 it had crossed a million daily users and around two billion dollars in annualized revenue, which is most of why it is the default many builders reach for.

Windsurf began as Codeium's editor and built its name on Cascade, an agent that plans and executes multi-step changes. After a turbulent year of ownership changes (below), it is now owned by Cognition, the company behind the Devin coding agent. As of June 2, 2026 it has been rebranded Devin Desktop, and its whole framing shifted: it opens on an agent command center, not a blank editor. You brief agents, watch them work in a board, and drop into the code to review.

The one difference that matters most

If you remember one thing, remember this. Both tools can autocomplete, chat, and run agents. What differs is the center of gravity, the thing the product assumes you came to do.

Cursor is for the builder who wants to stay in the code and have AI make the typing faster and the edits smarter. Devin Desktop is for the builder who wants to describe a task, hand it off, and review the diff. Neither is more advanced. They are cases for two different ways of working, and your answer to "which feels right" is most of the decision.

The ownership saga, kept straight

You cannot read about Windsurf in 2026 without hitting the corporate drama, and it matters because it explains the rebrand and the roadmap. Here is the sequence, verified and in order.

• May 2025: OpenAI agrees to acquire Windsurf for about $3 billion.
• July 2025: the deal collapses, reportedly because Microsoft's partnership with OpenAI gave it rights to any IP OpenAI acquired.
• July 2025: Google pays roughly $2.4 billion to license Windsurf's technology and hire its CEO Varun Mohan, co-founder Douglas Chen, and key researchers into Google DeepMind. This was a hire-and-license, not an acquisition.
• 2025: Cognition, the company behind the Devin coding agent, acquires what remains: the product, the brand, the IP, roughly 250 staff, and the revenue.
• June 2, 2026: Cognition rebrands the editor to Devin Desktop.

Cursor's owner had its own headline. In June 2026, SpaceX agreed to buy Anysphere, Cursor's maker, for $60 billion in an all-stock deal, days after SpaceX's own public offering. As of this writing the deal is expected to close in the third quarter, pending regulatory approval, so it is agreed but not yet final. Cursor keeps shipping in the meantime.

Models: many versus fast

The models a tool can run shape what it is good at. Here the two make different moves.

Cursor is model-flexible. You can route a task to Anthropic's Claude, OpenAI's GPT, or its own Composer model, and pick per task. Composer is built for speed on everyday edits; Claude and GPT come in for the hard reasoning. The pitch is that you are not locked to one provider, and you can spend the expensive models only where they earn it.

Windsurf / Devin Desktop also offers frontier models from Anthropic and OpenAI, but it leans on its own SWE-1.5 family, a coding model tuned to be very fast and to handle a large share of agent work cheaply. The thesis is that a fast in-house model running most of the loop, with frontier models for the hard parts, keeps the agent responsive and the cost down.

For most builders this nets out as: Cursor gives you more explicit control over which brain runs your task; Devin Desktop optimizes the agent loop around its own fast model so you think about it less. Both let you reach for a frontier model when the problem is genuinely hard.

Agents and code review

This is where the editor-first versus agent-first split shows up in features you will use daily.

Cursor runs background agents that clone your repository, work on a task in the cloud, and open a pull request when done; you can run several in parallel. Its most distinct feature is Bugbot, a dedicated AI code review tool: it reviews your pull requests on GitHub, comments on real defects (logic errors, security holes, race conditions, bad error handling) while skipping style nitpicks, and gives you a one-click path to fix the issue back in the editor.

Windsurf, now Devin Desktop, comes from the team that built Devin, an agent designed to take an engineering task end to end. So its agent story is the product, not a feature bolted on: you brief agents, they plan and execute, and review and fixes happen inside that loop. The June 2026 rebrand pushed this further with an agent command center and Devin Local, the successor to the old Cascade agent, as the default way you work.

Where each one runs

One practical split: how far each reaches beyond its own window. Cursor is its own editor, full stop. If you live in Cursor, you get everything; if you want Cursor's brain inside another editor, you do not.

Windsurf has long shipped plugins for other editors: JetBrains IDEs, Vim and Neovim, Visual Studio, Xcode, and more, in addition to its own VS Code-based app. If your team is split across JetBrains and VS Code, or you refuse to leave your JetBrains setup, that breadth is a real advantage, and it survived the rebrand (the plugins are still branded Windsurf for now). Cursor concentrates on making one editor excellent instead.

Pricing in 2026

Pricing in this category changes often, so treat these as a snapshot to check before you buy, not a contract. The headline: as of mid-2026 the old "Windsurf is cheaper" line is out of date. Both have a free tier and a $20 Pro tier.

The metering models differ in a way that affects how you feel the cost. Cursor gives you a dollar credit pool: unlimited use of its Auto mode, and a meter that runs only when you call a premium model. Windsurf moved off credits to daily and weekly quotas that refresh, which removes the end-of-month "out of credits" cliff some users hit, at the cost of a daily ceiling. Neither is plainly cheaper; it depends on whether your usage is bursty or steady, and how often you reach for frontier models.

How these compare to Copilot and Claude Code

"Cursor vs Windsurf" is the common framing, but two other names belong in the decision, because builders often ask about Copilot alternatives and end up here.

GitHub Copilot was designed as AI inside the editor you already use, and at $10 a month for Pro it is the cheapest of the group. If you mostly want better autocomplete and a chat in VS Code or a JetBrains IDE without switching editors, Copilot is a reasonable and inexpensive choice. Cursor and Windsurf are full editors built around AI, with stronger multi-file agents that plan a change, edit across files, run tests, and open a pull request. You are paying more for a deeper agent, not just nicer completion.

Claude Code is the terminal-first option: an agent that lives in your shell rather than an editor, and a tool many builders run alongside Cursor or Devin Desktop rather than instead of them. If your work is heavy on running commands, refactors, and repository-wide tasks, it pairs naturally with either editor.

Which should you pick?

There is no single best AI code editor, only the best fit for how you work and what you build. Use this flow, then trust a short trial over any review (both free tiers exist for exactly this).

Lean Cursor if you want to stay in the code, value picking your model per task, want a named PR-review bot in Bugbot, and like one polished editor. Lean Windsurf / Devin Desktop if you want to brief agents and review their output, your team is spread across JetBrains and other editors, or you want an agent-manager workflow as the default. Lean Copilot if you want to stay in your current editor and spend less, and add Claude Code if much of your work is terminal-shaped. When in doubt, run a real task through the two free tiers and let your own codebase decide.

Glossary

AI code editor

A code editor with AI built into the core workflow (completion, chat that edits files, and agents), as opposed to a plugin added to a plain editor. Cursor and Windsurf are the leading examples.

VS Code fork

An editor built from the open-source code of Visual Studio Code. It keeps the familiar interface and runs most VS Code extensions. Both Cursor and Windsurf are forks.

Agent

An AI that works in a loop: it plans, takes actions such as editing files or running commands, checks the result, and continues until a task is done. Cursor's background agents and Windsurf's Cascade and Devin Local are agents.

Composer

Cursor's own in-house coding model, tuned for fast edits, used alongside frontier models from Anthropic and OpenAI.

Cascade / Devin Local

Windsurf's agent. Cascade was the original; Devin Local is its successor under the Devin Desktop rebrand.

SWE-1.5

Windsurf's own fast coding model, built to run most of the agent loop cheaply while frontier models handle the hardest steps.

Bugbot

Cursor's AI code review tool. It reviews pull requests on GitHub, comments on real bugs, and offers a one-click fix in the editor.

Devin Desktop

The current name for the Windsurf editor after Cognition's rebrand on June 2, 2026. Same product, agent-manager-first framing.

Credit pool vs quota

Two ways a plan meters AI use. Cursor gives a dollar credit pool that premium models draw down; Windsurf uses daily and weekly quotas that refresh.

Frequently asked questions

What is the difference between Cursor and Windsurf?

Both are AI code editors built as forks of Visual Studio Code, so they look and feel familiar and run your existing VS Code extensions. The practical differences are focus and ownership. Cursor (made by Anysphere) leads on inline editing speed, model choice, and its own Composer coding model, and SpaceX agreed to buy Anysphere in June 2026. Windsurf, now rebranded Devin Desktop after Cognition acquired it, leads with an agent-manager interface: you brief one or more agents and review their work, with the editor built around that loop rather than the other way around.

Is Windsurf still called Windsurf in 2026?

No. On June 2, 2026, Cognition rebranded the Windsurf editor to Devin Desktop and shipped it as an over-the-air update. Your plan, pricing, settings, and extensions carry over unchanged, and the JetBrains and other IDE plugins are still branded Windsurf for now. The bigger change is positioning: Devin Desktop opens on an agent command center, and Devin Local is the successor to the old Cascade agent. People still search for "Windsurf," so the name will linger for a while.

What happened to Windsurf and OpenAI?

In May 2025 OpenAI agreed to buy Windsurf (then the company Codeium) for about $3 billion. The deal collapsed in July 2025, reportedly over Microsoft's contractual rights to OpenAI's IP. Google then paid roughly $2.4 billion to license Windsurf's technology and hire its CEO Varun Mohan, co-founder Douglas Chen, and key research staff into Google DeepMind. Cognition, the company behind the Devin coding agent, acquired what remained: the product, the brand, the IP, and most of the team.

Is Cursor or Windsurf better for beginners?

Both are approachable, and both run on a free tier you can start with today. Cursor tends to suit a beginner who wants fast, helpful autocomplete and a chat that edits files, working much like a smarter VS Code. Devin Desktop (Windsurf) leans toward briefing an agent to do a task and reviewing the result, which is powerful but asks you to think in terms of delegation sooner. If you want to learn by watching edits happen as you type, start with Cursor; if you want to practice directing an agent, start with Devin Desktop.

How much do Cursor and Windsurf cost in 2026?

As of mid-2026 both have a free tier and a $20-per-month Pro tier, so the old "Windsurf is cheaper" framing no longer holds. Cursor adds Pro+ at $60, Ultra at $200, Teams at $40 per user, and custom Enterprise pricing; its paid plans include a credit pool equal to the price, where Auto mode is unlimited and only premium frontier models draw down credits. Windsurf (Devin Desktop) moved from credits to daily and weekly quotas in March 2026, with Pro at $20, a $200 Max tier, Teams at $40 per user, and Enterprise. Check both sites before you buy; these plans change often.

Which AI editor has better code review?

Cursor ships the more visible code-review feature: Bugbot reviews your pull requests on GitHub, comments on real bugs (logic errors, security holes, race conditions, bad error handling) while ignoring style nits, and offers a one-click fix back in the editor. Windsurf, now Devin Desktop, comes from Cognition, whose Devin agent was built for autonomous engineering tasks including review and fixes, so review is woven into the agent flow rather than a separate named product. If you want a dedicated PR reviewer bot, Cursor's Bugbot is the clearer pick today.

Are Cursor and Windsurf good GitHub Copilot alternatives?

Yes, and they are the two editors most teams compare against Copilot. Copilot was designed as AI inside your existing editor and is cheaper at $10 a month for Pro; Cursor and Windsurf are full editors built around AI, with stronger multi-file agents that can plan a change, edit several files, run tests, and open a pull request. If you mostly want better autocomplete in the editor you already use, Copilot is fine and cheap. If you want an agent that takes a task and does it, Cursor or Windsurf is the upgrade, and Claude Code is the terminal-first alternative many builders run alongside either one.

Should I worry about the SpaceX and Cognition acquisitions?

Treat them as facts to watch, not reasons to panic. SpaceX agreed in June 2026 to buy Anysphere, Cursor's maker, for $60 billion in stock, with the deal expected to close in the third quarter pending regulatory approval, so it is not final yet. Windsurf is already owned by Cognition and rebranded to Devin Desktop. Both products keep shipping. The real risk for either tool is the ordinary one: roadmaps, pricing, and model access can shift under new ownership, so avoid staking a workflow on a single feature that only one vendor offers.

Where to go next

You now have the framework: the one design difference that splits them, the ownership story that explains the rebrand, how the models and agents and code review actually differ, what both cost, and a flow to pick by use-case. The honest close is the one we opened with: try both on your own work for a day, because the free tiers make the decision cheap and your codebase is the only benchmark that counts.

For the moves in AI developer tools as they happen (new models, agent features, pricing changes like the ones above), the AI devtools daily digest tracks the beat, and the daily briefing reads the wire each morning and closes with one falsifiable call we settle in public.
