What is Cursor?

Cursor is an AI-powered code editor built as a direct fork of Visual Studio Code. It integrates advanced large language models directly into the editing experience. Developers can write, refactor, and debug code through natural language conversations with an AI that understands the entire project.

Our workflow benefits greatly from this local, desktop-based approach. Unlike browser-based AI coding tools like Lovable or Bolt.new, this application runs entirely on your machine. You get the full power of a desktop IDE alongside artificial intelligence.

”Cursor’s integration of the Claude 3.5 Sonnet model directly into the local IDE environment creates a frictionless coding experience that web-based platforms cannot match.”

Real SaaS applications require authentication systems, complex database schemas, and dozens of interconnected files. You need a tool that holds all of this context simultaneously to avoid breaking existing features. Cursor leverages Anthropic’s Claude 3.5 Sonnet and OpenAI’s GPT-4o to handle these complex connections seamlessly.

Key Features for SaaS Development

Multi-File Context Understanding

We consider multi-file context to be this editor’s defining strength. The @codebase command allows the AI to index your entire project directory and map relationships between files. Asking the assistant to create a new API endpoint prompts it to automatically reference your existing route patterns and type definitions.

In our testing with a Next.js application containing over 120 files, the system correctly referenced the authentication middleware. This high level of contextual awareness eliminates the tedious copy-paste workflow required by older assistants.

Backend Logic Generation

SaaS applications depend heavily on secure and efficient backend infrastructure. Cursor handles backend code generation with impressive competence across various critical patterns.

Our engineers tested the editor on several complex backend tasks:

• Authentication flows: Generated complete JSON Web Token (JWT) implementations that integrated perfectly with our existing middleware.
• Database queries: Produced highly optimised Prisma and Drizzle ORM queries containing complex joins.
• API route handlers: Created RESTful endpoints with proper validation and response formatting.
• Payment integration: Scaffolded Stripe webhook handlers requiring almost no manual correction.

The quality of this generated code surpasses what we experienced with Windsurf and similar browser-based tools. Generating code that matches your established project patterns is far superior to inserting generic boilerplate.

Inline Editing and Composer

We primarily interact with the AI through two distinct modes. Inline editing lets you select a specific block of code and ask the assistant to modify it directly in the file. The Composer mode opens a separate panel for orchestrating large feature additions across multiple files.

Our development team used Composer mode for approximately 70 percent of our daily tasks. Building a new feature often requires coordinating multiple moving parts:

• Updating API route handlers
• Running database migrations
• Modifying frontend React components
• Adjusting CSS utility classes

Composer allows you to plan and execute all of those file changes simultaneously within a single chat window.

VS Code Extension Ecosystem

We appreciate that every VS Code extension transfers over immediately. Because this editor is a direct fork, tools like ESLint, Prettier, and Tailwind CSS IntelliSense work flawlessly upon installation.

Adopting an entirely new workflow is a major barrier for busy development teams. Keeping your existing keyboard shortcuts and colour themes makes the transition nearly frictionless.

Our Testing Process

We evaluated this tool over a 12-week period across two active software projects.

• Project Alpha: A multi-tenant management platform built with Next.js 14, Prisma, PostgreSQL, and Stripe. This codebase contained approximately 180 files at completion.
• Project Beta: An API analytics dashboard built with SvelteKit, Drizzle ORM, and ClickHouse. This smaller project contained roughly 90 files.

Our metrics focused on real-world development productivity. The team tracked the time required to implement common features like authentication and payment gateways. We then ran parallel tests against Windsurf and Claude Code to establish a clear baseline.

Detailed Analysis

SaaS Code Quality

We rate the generated code quality a 9.5 out of 10. The AI consistently produced production-grade logic during our testing phase. Asking the system to build an authentication layer resulted in a secure implementation with proper token refresh logic.

This tool occasionally falls short when handling obscure edge cases. The AI tends to generate the happy path first and requires a secondary prompt to add comprehensive error boundaries. This minor limitation is easily managed with a quick follow-up request.

Backend Capability

We give the backend generation capabilities a solid 9.0 out of 10. Database queries are well-structured, and business logic remains cleanly separated from transport layers. The system excels at generating complex Prisma queries involving nested relations.

During our database tests, the AI successfully drafted a 40-line ClickHouse aggregation query on its first attempt, saving our lead engineer at least an hour of manual syntax checking.

A slight deduction comes from minor struggles with real-time application features. WebSocket implementations and server-sent events demanded more manual guidance than standard request-response patterns. Most standard business applications will not be affected by this specific limitation.

Multi-File Handling

We consider the @codebase feature to be a revolutionary addition to the development workflow, earning a 9.5 out of 10. Requesting a team billing feature prompted the AI to correctly identify our existing infrastructure:

• The active Stripe webhook integration
• The team model inside our database schema
• The exact billing page UI component

It then generated the necessary code to wire these disparate components together seamlessly.

Performance does degrade slightly when working within massive monorepos. Once Project Alpha exceeded 150 files, the context retrieval occasionally missed utility functions hidden deep in nested directories. Restricting the AI’s search using specific @file mentions resolves this issue quickly.

Deployment Ease

We scored the deployment configuration abilities an 8.5 out of 10. The editor does not host applications directly, but it excels at generating the necessary deployment configurations. Asking the AI to create Docker files or Vercel deployment setups yielded highly accurate results.

Browser-based platforms like Lovable offer convenient one-click hosting for simple projects. Serious production environments require custom configurations, making this editor’s approach much more appropriate for professional engineers.

Value for Money

We firmly believe the Pro plan offers exceptional value, earning a 9.0 out of 10. At $20 per month, it is an easy justification for any professional developer.

Our data shows an average saving of 8 hours per week on complex tasks. In Malaysia, the median software engineer salary is approximately RM 6,500 per month, which breaks down to roughly RM 40 per hour.

ROI Metric	Value
Monthly Subscription	RM 95 ($20)
Hours Saved Monthly	32 Hours
Developer Hourly Rate	RM 40
Total Value Saved	RM 1,280

The Business tier at $40 per user adds vital privacy controls. Engineering teams benefit from centralized billing and a Zero Data Retention privacy mode that prevents your code from being used to train future models.

Pricing Breakdown

• You are a complete beginner seeking a fully managed environment (try Bolt.new or Replit).
• You refuse to pay a monthly subscription fee for development tools.

How Cursor Compares to Alternatives

We place this application firmly at the professional end of the AI coding spectrum. Windsurf serves as a close competitor, offering a lower entry price but featuring a less mature extension ecosystem.

When evaluating the market, three distinct categories emerge:

• Terminal Agents: Claude Code runs directly in the command line for developers who prefer text-only interfaces.
• Rapid Prototypers: Lovable and Bolt.new prioritise speed over deep architectural control for simple MVPs.
• Full IDE Replacements: Cursor and Windsurf provide complete desktop environments for heavy production builds.

GitHub Copilot remains a popular choice at $10 per month. It lacks the advanced Composer mode and forces you to use OpenAI’s models, making the higher price of Cursor easily justifiable for heavy users.
