In-depth Report

Windsurf is an AI programming assistant launched by Codeium. After its launch in 2024, it quickly became a core player in the field of AI programming tools. After being acquired by Cognition AI (the company behind Devin) in 2025, Windsurf integrated the cloud agent Devin and the local agent Cascade to form a unique "AI Flow" workflow. According to official data, Windsurf has more than 1 million users and more than 4,000 enterprise customers, and about 94% of user-generated code is written by AI. The adjustment of the pricing plan in March 2026 has triggered heated discussions in the community, but from the perspective of product functions, Windsurf has maintained its differentiated positioning in the competition with Cursor and Claude Code by virtue of multi-model support, MCP integration and a relatively friendly entry experience.
Windsurf originally entered the market as Codeium, a startup focused on AI code completion. In the fierce competition among AI programming tools, Windsurf has gradually evolved from a simple code completion plug-in into a complete AI integrated development environment. The acquisition by Cognition AI in 2025 was an important turning point in the company’s history. Cognition AI is best known for developing its autonomous AI programming agent Devin, and the acquisition enables Windsurf to deeply integrate cloud agent capabilities with on-premises development environments. The company’s CEO is Garry Tan, who has important influence in Silicon Valley and has invested in many technology companies. Windsurf's product vision is "Where developers are doing their best work", which emphasizes reducing developers' context switching and making it possible to complete unlimited multiple tasks in one editor.
Windsurf's core innovation is the "AI Flow" workflow paradigm, which combines local agents with cloud agents. Cascade is a local AI agent that runs on the developer's local machine and can detect and repair lint errors in real time and understand code base semantics; Devin is a cloud-based autonomous agent that can perform complex tasks on independent machines and is suitable for entrusting complete functional development to it. These two agents are managed uniformly through the Agent Command Center and presented in a Kanban-style task board, allowing developers to clearly control task progress. Cascade local proxy is one of the key features that differentiates Windsurf from competing products. Not only can it perform code completion, it can also understand the context of the entire code base and perform cross-file refactoring. The CodeMaps function makes complex code bases clear at a glance, helping developers move from "guessing" to "understanding". This is a demand scenario that is less covered by other AI programming tools. MCP (Model Context Protocol) support enables Windsurf to connect to external tools and service ecosystems. Supports common development tools such as Figma, Slack, Stripe, PostgreSQL, Playwright, and Neon, allowing AI agents to call real tools to complete end-to-end tasks. Multi-model support is another strength of Windsurf. It fully supports mainstream model providers, including OpenAI, Anthropic, DeepSeek, etc., and developers can flexibly switch models according to task requirements. The drag-and-drop image construction function allows developers to directly drag and drop design draft images, and Windsurf will generate corresponding code implementations based on the image content. This is valuable for rapid prototyping. Compared to Cursor, the advantage of Windsurf is a more user-friendly onboarding experience. According to user feedback, Windsurf’s operation logic is more intuitive and requires less programming experience. At the same time, multi-model support allows users to choose different models based on cost performance. The disadvantage is that the ecosystem started late, and the plug-ins and workflows are not as rich as Cursor. Compared with Claude Code, Windsurf provides a more complete graphical interface and visual task management, and is more friendly to developers who are not familiar with the command line. However, Claude Code's deep integration in pure command line scenarios is still its unique positioning.
Windsurf adopts a tiered subscription model, and the personal version has three tiers: Free ($0/month), Professional (Pro, $20/month), and Max (Max, $200/month). The team version is charged per person ($40/person/month), and the enterprise version requires contacting the sales team. The free version provides light usage and is suitable for daily code completion experience. The Pro version offers standard usage and all premium models, including the SWE-1.5 model, for professional developers. The Max version provides heavy usage and adds enterprise-level features such as SSO, RBAC, and hybrid deployment. The team version is suitable for small-scale collaboration, and the enterprise version is suitable for large-scale organizations. In March 2026, Windsurf changed its pricing plan from "point deduction per use" to "daily/weekly quota", and the price of the professional version remained unchanged. This change sparked discussion in the community, with some users believing that the new solution provides a more stable experience.
Judging from the feedback from the English community and Chinese public accounts, Windsurf has received many positive reviews. Well-known developer Avi Schiffmann said on social media that Windsurf is better to use than Cursor. Another developer, Andrew Brown, predicts Windsurf will win the race for AI programming assistants. User Jon Myers believes that Windsurf's user experience is more suitable for programming novices than Cursor because the interface is more intuitive and there are fewer steps. Feedback from the Chinese community has been equally positive. The public account article believes that Windsurf’s CodeMaps function makes it easier to understand complex code and is an effective tool to “say goodbye to Vibe Coding”. Many users mentioned that Windsurf’s “multi-model unlimited refill” solution has practical value in the domestic development environment. Of course, some users pointed out shortcomings. After using it for a day, some users felt that it was “still not that good”. The main problem focused on the processing capabilities of certain complex tasks. Some users mentioned that after the pricing adjustment, the cost in high-frequency usage scenarios has increased. There are also technical users concerned about the stability of API proxies and model calls.
Reviews of AI programming tools in 2026 generally list Windsurf as one of the three mainstream choices (tied with Cursor and Claude Code). Industry media believe that Windsurf’s differentiated advantage lies in its “AI Flow” integration of local and cloud agents, as well as its relatively loose model selection space. An article from Tencent Cloud Developer Community pointed out that Windsurf has successfully transformed from a code completion plug-in into an AI native IDE with its unique AI Flow workflow and the strategic opportunity of being acquired by Cognition AI. Zhihu and Hengping articles in major technology communities generally believe that Windsurf, Cursor, and Claude Code each have their own emphasis, and which tool to choose depends on the specific usage scenarios and team preferences.
The main controversy Windsurf faces centers on its pricing scheme. The plan adjustments in March 2026 triggered heated discussions in the community, and some users believed that the changes were not as flexible as before. In addition, as a relatively new product, Windsurf's plug-in ecology and community resources are not as rich as Cursor, which may affect developers' willingness to migrate. From the perspective of technical risks, AI programming tools generally face issues such as code security review and division of intellectual property responsibilities, and Windsurf is no exception. Users still need to conduct manual review when using AI-generated code in a production environment.
Windsurf is suitable for the following groups: novice programmers who want a more friendly AI-assisted experience; developers who need multiple model options; enterprise users who need local agent capabilities; teams who are accustomed to graphical interface operations rather than command lines. It is not suitable for the following groups: users who pursue the ultimate community plug-in ecosystem; technical teams who require deep CLI integration; individual developers who are extremely cost-sensitive. In terms of alternatives, those who pursue a mature ecosystem can choose Cursor, those who pursue pure command line integration can choose Claude Code, and those who pursue free open source solutions can choose Roo Code or other open-source alternatives.
Windsurf is one of the core players in the AI programming tools track in 2024-2026. It uses the "AI Flow" workflow to integrate local agents and cloud agents with differentiated positioning, maintaining a place in the competition with Cursor and Claude Code. The scale of more than 1 million users and 4,000 enterprise customers validates the value of its products. After being acquired by Cognition AI in 2026, Windsurf’s integration capabilities in the field of AI agents are expected to be further enhanced. For developers looking for an AI programming tool with low entry barriers and rich multi-model options, Windsurf is worth paying attention to.

I have been a paid user of Windsurf for six months, let me talk about my real experience. Cascade is indeed better than Cursor in terms of multi-file reconstruction and migration. The Flows mode can define the sequence of steps, and the overall situation will not be disrupted if the requirements are paused midway. After Memories learned my coding habits, the generated code became more and more in line with the project style. But there are many shortcomings: the Tab completion accuracy is about 10 points lower than Cursor, and it often overturns when dealing with TypeScript generics; the price change in March cut off the free quota, and the community was full of criticism; the customer service basically only has bots, and you have to wait for a long time when problems arise. Pro $15/month is a good value for money, but it is unrealistic to expect it to completely replace Cursor. It is recommended to install both and draw on the strengths of each.

Cascade really does the job, not just fancy.

After using Windsurf for two weeks, Cascade is really good for cross-file reconstruction, but the daily completion speed is not as good as Cursor.

It took me a long time to get used to it after switching from VS Code. Most of the plug-ins can be used, but there is a problem with the rendering of GitLens. Cascade is really powerful. Let it add Pydantic verification to FastAPI, and it can analyze all 11 endpoints by itself. But sometimes as the context gets longer, it forgets what was changed before.

The free version gives you 25 credits, which is enough for fishing.

The Memories function is amazing, and it starts to understand your coding style after using it for a few days.

After comparing it with Cursor for a week, I concluded that each has its own merits. Windsurf's Cascade is more stable in long-term tasks and will not go astray like Cursor Composer. But the quality of tab completion is indeed a notch behind, especially when TypeScript complex type inference is performed.

It’s 5 yuan cheaper than Cursor, but the completion is really inferior.

I got into Windsurf because the free version is relatively large, and I bought the Pro directly after using it for a month. Cascade is a real agent. It does not give you suggestions to change by yourself. Instead, you describe your needs and it automatically analyzes the code base, formulates a plan, changes multiple files, runs tests, and fixes bugs. I asked it to extract common logic into tool classes in a Java project with 100,000 lines of code, and accurately identified 17 duplicate codes. But when writing code in daily life, it is not as smooth as Copilot, and the Tab completion experience is worse. In addition, the resource usage is higher than that of VS Code. For computers with 8G memory, it is recommended not to open too large projects, otherwise the fan will spin wildly when Cascade is running.

The price change in March was too painful. Many features that were previously free to users now require payment.

My current workflow is Windsurf for project skeleton + major refactoring, and Cline for detailed development. Windsurf's free quota is sufficient, but in the last week of the month, the current limit is often triggered, and Cascade conversations directly slow down. Pro $15/month is still worth it.

Let Cascade migrate React class components to function components. 23 files were completed in 15 minutes.

After being acquired by Cognition, it was renamed Devin Desktop, but nothing changed other than changing the name. To be honest, I'm a little disappointed, I thought some of Devin's abilities would be integrated into it. At present, Cascade still has those functions, and we hope to add more agent capabilities in the future.

The Flows model can break down complex tasks into steps, and the tasks will not collapse if the requirements are changed midway.

Tip: Windsurf’s credits are refreshed on a daily basis, not a monthly basis, so don’t use them all at once.

Last week, I asked Windsurf to migrate an Express project from CommonJS to ESM. 23 files were changed one by one in dependency order, and a test was run after each change. It took 15 minutes and at least half a day to do it manually. This progressive strategy is slow but steady, and it went live immediately after the changes were made without any problems.

I tried it when Windsurf 2.0 was released. Cascade Agent is indeed more stable than Cursor Composer. It will not change a large number of files at once, but will proceed step by step according to dependencies, waiting for your confirmation at each step. But the problem is that this process is a bit slow. It takes more than ten minutes to change 20 files, unlike Cursor, which can be changed in a snap. For projects that require caution (such as production environment code), Windsurf's incremental strategy is safer; for rapid prototyping, Cursor's brute force approach is faster. Another point: Windsurf's JSON prompt words are actually quite flexible, but the learning cost is higher than Cursor.

I want to say a few words about Windsurf's pricing. Pro $15/month is 5 yuan cheaper than Cursor, but in actual use, if you use Cascade heavily, credits will be consumed quickly. I do about 10-15 Agent conversations every day, and the 500 Pro credits are used up in half a month, so I can only use them sparingly in the following days. In addition, its credits do not roll over and are cleared at the end of the month. In this regard, Cursor’s $20 all-inclusive package is actually more worry-free. But the free version of Windsurf is really generous and is enough for students or light users.

Windsurf supports multi-model switching, which is very useful in domestic scenarios. If the customer is a state-owned enterprise or financial institution, there may be compliance issues using the U.S. closed-source model. Windsurf can switch to domestic models, which Cursor and Copilot cannot do. But the problem is that the access speed in China is not stable, and Cascade response has to wait several seconds during peak periods. In addition, there are too few Chinese documents and community resources. If you encounter problems, you can basically only search in the English community.

I have been evaluating AI programming tools for some time. Windsurf gives me the feeling that its upper limit is very high and its lower limit is unstable. The combination of Cascade+Flows+Memories indeed represents the future direction of AI IDE, turning AI from a suggester to an executor. However, the execution quality varies. Sometimes I am amazed by the god-level code generated, and sometimes I make low-level mistakes in the simplest places. It is recommended that novices try out the free version first to see if the way Cascade works is suitable for them.

The free version of Windsurf is enough. Daily curd does not cost money at all. The Pro version is reserved for users who just need it.

Cascade mode is really good, and code completion is much faster than before. However, sometimes the same code is generated repeatedly and needs to be modified manually.

After using Windsurf for a week, I feel it is more suitable for novices than Cursor. The operation logic is simpler and does not require so many shortcut keys.

It's really fun to switch between multiple models. It's fast to change the model and regenerate it. You don't have to wait all the time.

Roy.SimmonsII

It is indeed different after being acquired by Cognition. The code quality of the SWE-1.5 model has improved significantly.

The free version has a daily limit. If you use it frequently, you still have to buy Pro. 20 dollars a month is acceptable.

The CodeMaps feature is so useful! I was completely confused when I looked at other people's code bases, but now the structure is clear at a glance.

Windsurf works great with MCP. You can adjust Figma and Stripe directly in the editor, eliminating the need to switch back and forth between software.

Compared with Cursor, Windsurf is more suitable for progressive development, and Cursor is suitable for direct Composer to generate the entire code.
