Stellify vs Cursor vs Windsurf

The Short Version

Cursor and Windsurf are AI-powered code editors that work with any codebase. They're excellent for adding AI assistance to existing projects.

Stellify is a different beast: a constrained development platform where AI generates structured code, not text files. It's purpose-built for production-grade Laravel and Vue applications.

They're not direct competitors — they solve different problems. This page will help you understand which approach fits your needs.

Quick Comparison

The Fundamental Difference

Cursor and Windsurf treat code as text. AI reads your files, suggests changes, and writes new text. This is flexible — it works with any language, any framework, any project.

Stellify treats code as structured data. Your methods, statements, and UI elements are stored as JSON with relationships. When AI writes code, it creates structured records — not freeform text.

Why does this matter?

Text-based AI coding (Cursor, Windsurf)

• Pros: Works anywhere, integrates with existing workflows, supports every language
• Cons: AI can hallucinate APIs, break syntax, introduce subtle bugs, or write inconsistent code across files

Structured AI coding (Stellify)

• Pros: AI is constrained to valid operations, relationships are tracked, code follows consistent patterns
• Cons: Only works with Laravel/Vue, requires learning a new platform, less flexibility

Think of it like the difference between a word processor and a spreadsheet. Both can store data, but one lets you target a specific cell while the other treats everything as flowing text.

When to Use Each Tool

Choose Cursor or Windsurf if:

• You have an existing codebase in a language that isn't PHP/Laravel
• You want AI assistance while keeping your current workflow
• You're working with Python, Go, Rust, or other non-PHP stacks
• You need maximum flexibility
• You're comfortable reviewing and fixing AI output

Choose Stellify if:

• You're building a new web application from scratch, or have an existing Laravel project
• You need production-grade code that handles sensitive data (healthcare, finance, legal)
• You want AI that can't hallucinate invalid code structures
• You're building with Laravel and Vue (or willing to)
• You want to deploy faster without babysitting AI output

Use Them Together

Here's something most comparison pages won't tell you: you can use Stellify with Cursor or Windsurf.

Stellify has an MCP server that connects to any MCP-compatible AI agent — including Claude Code running inside Cursor or Windsurf. Your AI gets Stellify's structured code tools while you work in your preferred editor.

You can also export your Stellify project as standard Laravel files and continue development in any editor. There's no lock-in.

The Vibe Coding Problem

"Vibe coding" — letting AI write code without careful review — works fine for prototypes and side projects. But it's a liability for production applications.

When AI writes text-based code, it can:

• Call APIs that don't exist
• Introduce security vulnerabilities
• Create inconsistent patterns across your codebase
• Write code that passes tests but fails edge cases

Cursor and Windsurf are aware of this — they've built features like code review and inline diffs to help you catch issues. But the fundamental architecture means AI can still write anything.

Stellify's constraint-based approach means certain classes of errors are impossible. AI can't call a method that doesn't exist because it's working with method UUIDs, not text strings. It can't break your file structure because the structure is enforced by the data model.

This is the tradeoff: less flexibility for more reliability.

Cursor vs Windsurf

Since you might also be comparing Cursor and Windsurf directly:

• Cursor pioneered the AI-native editor space. It has a larger user base, more refined features, and strong community momentum.
• Windsurf (by Codeium) is newer and slightly cheaper. It emphasizes "agentic" workflows where AI takes more autonomous action.

Both are solid choices. If you're choosing between them, try both free tiers and see which UX feels better for your workflow.

Summary

There's no single "best" tool — it depends on what you're building.

If you're tired of reviewing AI output for subtle bugs and want to ship production code faster, try Stellify free.

If you need AI assistance on an existing codebase or non-Laravel stack, Cursor or Windsurf will serve you well — and you can still connect them to Stellify via MCP when you need structured code generation.
