Windsurf vs Cursor: Which AI IDE for TypeScript Developers?

Two AI IDEs. Both fork VS Code. Both add AI-powered editing, chat, and multi-file generation. But they make different bets on how AI should integrate with your workflow.

Windsurf is built by Codeium. Its core feature is Cascade, an agentic flow system that chains actions across your project. Cursor is built by Anysphere. Its core feature is Composer 2, a multi-file editor backed by frontier model benchmarks and fast custom models.

If you write TypeScript, here is how to decide between them.

Cascade vs Composer 2

Cascade is Windsurf's agentic workflow engine. You describe a task, and Cascade breaks it into steps: read files, edit code, run commands, check results. It operates as a flow, where each step feeds into the next. Think of it as a pipeline that understands your codebase.

For broader context, pair this with Cursor vs Claude Code in 2026 - Which Should You Use? and Every AI Coding Tool Compared: The 2026 Matrix; those companion pieces show where this fits in the wider AI developer workflow.

Composer 2 is Cursor's multi-file editing system. It rewrites across files simultaneously, shows inline diffs, and lets you accept or reject changes per hunk. It is backed by Cursor's own models that score at or near the top of SWE-Bench.

The difference matters in practice.

Cascade excels at sequential tasks. "Add a new API route, write tests for it, then update the client SDK." Each step depends on the previous one, and Cascade chains them naturally.

Composer 2 excels at parallel edits. "Rename this interface across 30 files." Composer rewrites everything at once and shows you every diff.

TypeScript Experience

Both tools understand TypeScript deeply. They parse types, follow imports, and generate code that passes tsc. But the editing experience differs.

Cursor's inline completions are the best in the business for TypeScript. You start typing a function, and it predicts the implementation based on your types, your patterns, and the surrounding code. The tab-complete flow is fast enough that it feels like the IDE reads your mind.

// Start typing a Zod schema...
const projectSchema = z.object({
  // Cursor autocompletes fields based on your existing Project type

Windsurf has autocomplete too, powered by Codeium's completion engine. It is good, but Cursor's completions are noticeably better for TypeScript. They pick up on generics, utility types, and conditional types more accurately.

Windsurf's Cascade is stronger for multi-step TypeScript workflows. "Scaffold a tRPC router with input validation, connect it to the database layer, and generate the client hooks." Cascade handles the chain without you re-prompting at each step.

Context and Codebase Awareness

Both tools index your project for context. Cursor uses its own retrieval system to pull relevant files into the prompt. Windsurf indexes with Codeium's engine and adds Codemaps, a feature that builds a semantic graph of your codebase.

For a typical Next.js TypeScript project (100-300 files), both do a good job. You can ask either tool about a function in a different file, and it will find it.

Where they diverge:

• Cursor lets you manually tag files with @file to force them into context. This gives you precise control over what the model sees.
• Windsurf leans on automatic context selection through Cascade. It decides what is relevant. Less control, but less work.

If you are the type of developer who wants to control every input to the model, Cursor's @file system is better. If you want the tool to figure it out, Windsurf's approach is less friction.

Pricing

Cursor Pro: $20/month. Includes 500 fast requests, unlimited slow requests, and access to multiple models (Claude, GPT, Cursor's own models).

Windsurf Pro: $15/month. Includes Cascade flows, Codeium completions, and access to frontier models.

Both have free tiers for individual developers. Both charge more for team and enterprise plans.

At these prices, the cost difference is irrelevant. Pick the tool that fits your workflow, not the one that saves you $5/month.

Models

Cursor bets heavily on its own models. Cursor's custom models score competitively on SWE-Bench and run fast. You also get access to Claude Sonnet, GPT-4.1, and other frontier models.

Windsurf ships SWE-1.5 (and newer iterations), trained specifically for coding with reinforcement learning. It runs at extremely high token throughput thanks to its Cerebras partnership. You also get access to Claude, GPT, and other models.

Both let you bring your own API key if you want to use a specific model.

What About CLI Tools?

Both Windsurf and Cursor are GUI editors. If you want a terminal-native experience, neither one is the answer. Tools like Claude Code, OpenAI Codex, and other CLI agents operate differently: they run in your terminal, edit files directly, and chain with shell commands.

The GUI and CLI approaches are complementary. Many developers run Cursor or Windsurf for interactive editing and a CLI tool for automation, CI pipelines, and large refactors.

Which One Should You Pick?

Pick Cursor if:

• Inline TypeScript completions matter most to you
• You want fine-grained control over context with @file
• You prefer seeing diffs and accepting changes visually
• Multi-file parallel edits are your primary workflow
• You want access to frontier benchmarks from Cursor's own models

Pick Windsurf if:

• You want agentic, multi-step workflows with Cascade
• Automatic context selection appeals to you
• You value the integrated Codeium completion engine
• Sequential task chaining is how you work
• You want high-throughput inference via SWE models

The honest answer: both are excellent. The gap between them is smaller than the gap between either one and plain VS Code. If you are writing TypeScript professionally and not using one of these, you are leaving speed on the table.

Try both for a week with your actual codebase. The free tiers make this easy. Your workflow will tell you which one fits.
