Windsurf IDE: Don’t Ditch Cursor Just Yet

Last month, right when Cursor’s servers crashed on a release deadline, I frustratedly switched my entire project to Windsurf IDE, hoping to find a perfect alternative. I used to think its “Cascade” architecture would completely solve the problem of comprehending large codebases, but after 30 days of real-world grinding, it turns out I was dead wrong.

🧠 What exactly is Windsurf IDE?

If you’ve been browsing tech forums lately, Windsurf is being hyped as a “Cursor killer.” At its core, it’s still an IDE built on the familiar VS Code foundation. The highlight is its deep integration with the most powerful AI models today, like Claude Sonnet 4.5 or GPT-5.

The core difference touted by the development team lies in the “Flow” and “Cascade” workflows. Instead of just acting as a chatbot to help type code, Windsurf tries to automate the entire process. It understands requirements, creates plans, and automatically writes code to modify files.

It sounds very appealing, especially for devs looking to optimize their time to focus on system architecture. It reminds me of the promises of absolute productivity I once analyzed in the post Deep Work in Tech: Cal Newport’s Illusion?.

✅ Rare Bright Spots: Small Tasks and Project Setup

Seamless boilerplate automation

Windsurf does an excellent job of scaffolding projects from scratch. Give it a prompt to create a Next.js app with Tailwind and Supabase, and it will run terminal commands in a snap. You can just sit back and watch it build the framework.

The power of Claude Sonnet 4.5

This model writes frontend code incredibly well. Windsurf knows how to call the Sonnet 4.5 API to handle complex UI components quickly and efficiently. If your project only has about a dozen files, the initial experience is fantastic.

⚠️ The Disillusionment with Large Codebases

The “local amnesia” syndrome

This is the main reason I downgraded my rating of Windsurf. When a project grows beyond 50 files, the Cascade feature starts showing fatal weaknesses. You ask it to fix logic in Service A, and it automatically modifies Controller B, breaking a series of test cases in the process.

Burning through tokens like water

Every time the Cascade flow runs, it automatically re-reads a bunch of unnecessary files in the directory. Your quota will evaporate in just a single morning of debugging minor bugs. Sometimes I wonder if its hidden API calling mechanism is any different from the kind of Tool Calling: Miracle or Scam? that companies are painting to drain users’ wallets.

🛑 Performance and Stability

Peak hour lag

Last Friday night, just when I needed to hotfix a production bug, Windsurf’s AI server just kept spinning for 5 straight minutes. It was a truly helpless feeling. A tool meant for professional engineers cannot afford such poor uptime.

⚖️ Quick Comparison: Windsurf vs. Cursor

Criteria	Windsurf IDE	Cursor	Notes
Codebase Comprehension	Poor (Easily loses context)	Very Good (Deep Indexing)	Cursor is still king here
Automation	Intuitive, auto-runs commands	Requires extra config	Windsurf wins on initial UX
Token Management	Excessive waste	Smart optimization	Windsurf burns quota fast
Stability	Average	Good	Windsurf often lags in the evening

🛠️ How to use Windsurf (if you still want to try)

Although I don’t rate it highly at the moment, if you’re curious, here’s how to use it without getting frustrated:

1. Use only for new projects: Or small microservices with under 20 files. Don’t be foolish enough to bring your company’s monolith in here.
2. Turn off Auto-apply: Always review code carefully before allowing it to overwrite existing files.
3. Limit Context: Instead of letting it scan the codebase indiscriminately, use @ to specify exactly which files it needs to read.
4. Choose the Right Model: Prioritize Claude Sonnet 4.5 for standard coding tasks over GPT-5 to avoid overly “creative” code that breaks existing logic.

❓ Frequently Asked Questions

Should I cancel my Cursor subscription for Windsurf?

Not yet. At least for now (May 2026), Windsurf isn’t mature or stable enough to fully replace Cursor in daily work.

Is Windsurf free?

They have a free version, but the quota is extremely meager. Just running a few complex Cascade flows will force you to upgrade to the Pro plan immediately.

Do Vietnamese devs experience much delay?

The issue isn’t the network connection; it’s mainly that their AI servers are frequently overloaded around 8-10 PM Vietnam time.

🎯 Conclusion

For many, searching for the perfect coding tool is as exhausting and time-consuming as reshaping a Dev Career After 30: The Roadmap Trap. Windsurf IDE has a great idea and a very pleasing UI design, but the execution suffers from too many fatal flaws. The reckless token burning and frequent loss of context when handling large projects make it feel more like an expensive toy than a real workhorse. For now, I’ve packed my things and headed back to Cursor.
