Quick Verdict

Decision Matrix (March 2026)

  • Choose Roo Code if: You want to stay in VS Code, need model flexibility, care about open source, or want custom AI modes with scoped permissions
  • Choose Cursor if: You want the fastest AI-assisted coding experience, don't mind paying $20/month, and are comfortable switching to a new editor
  • Either works if: You need an AI coding agent for multi-file edits. Both handle agentic tasks, just with different tradeoffs in speed vs flexibility.

Roo Code Token Savings (diff edits)

Cursor is more polished. Its tab completion, inline editing, and agent mode are tightly integrated into the editor. Tasks feel faster because the AI is baked into every interaction.

Roo Code is more open. Any model, any provider, custom personas, and transparent token costs. It lacks Cursor's speed but makes up for it with flexibility and zero vendor lock-in.

Pricing

Roo Code: Free Extension + API Costs

The VS Code extension is free forever. You pay your model provider directly for API tokens. Typical costs:

  • Light usage (Claude Sonnet 4): $5-15/month
  • Heavy agentic usage: $20-50/month
  • Budget setup (DeepSeek/Gemini Flash): Under $5/month

Optional cloud features: Cloud Free (token tracking), Pro ($20/month + $5/hour cloud tasks), Team ($99/month + $5/hour).

Cursor: Subscription + Credits

Cursor moved to a mixed pricing model in mid-2025:

  • Free: 50 premium requests/month, 500 basic model requests, limited agent
  • Pro ($20/month): Unlimited tab completion and auto mode, $20 in credits for premium models
  • Teams ($40/user/month): SSO, centralized billing, admin controls

If you burn through the $20 credit on premium models (Claude Sonnet 4, GPT-5.4), additional usage is billed at API rates. Basic model usage (Cursor's default) is unlimited on Pro.

Monthly Cost: Equivalent Workload

For a developer doing 3-4 hours of AI-assisted coding per day:

  • Cursor Pro: $20/month (may exceed credits with heavy premium model use)
  • Roo Code + Claude Sonnet 4: $15-30/month (variable)
  • Roo Code + DeepSeek: $3-8/month (variable)

Roo Code's diff-based editing saves ~30% on output tokens compared to full-file approaches. On large codebases, this adds up.

Editor Philosophy

Cursor: AI-Native IDE

Cursor forked VS Code and rebuilt it around AI. Tab completion, inline editing (Cmd+K), chat, and agent mode are first-class features integrated into the editor chrome. The AI understands your full repository structure, naming conventions, and architectural patterns.

The tradeoff: you leave VS Code. Your extensions and settings mostly transfer, but you're running a different application. Updates to VS Code arrive in Cursor with a delay. Some VS Code extensions don't work perfectly.

Roo Code: Extension in Your Editor

Roo Code lives in VS Code's sidebar. Your editor stays exactly as it is. All your extensions, keybindings, and themes work unchanged. The AI agent operates through VS Code's extension API.

The tradeoff: the AI can't modify the editor experience as deeply as Cursor can. There's no tab completion, no inline Cmd+K editing. Roo Code's interaction model is the sidebar panel: you describe a task, the agent plans and executes, you approve changes.

Cursor: Rebuilt Editor

AI woven into every interaction. Tab completions, inline edits, agent mode. Faster but requires switching editors. Some VS Code extension compatibility gaps.

Roo Code: VS Code Extension

Your existing editor, untouched. AI works through the sidebar. Slower but zero migration cost. Every VS Code extension works. Open source.

Agent Capabilities

Roo Code: Custom Modes + Personas

Custom modes define specialized AI agents with scoped tool permissions. A security reviewer mode can read code but not write files. An architect mode can plan but not execute commands. Five built-in modes ship with the extension, and the Mode Gallery offers community-created configurations.

Roo Code's diff-based editing (apply_diff) outputs only changed lines, saving tokens on large files. Model profiles let you switch between providers via a dropdown: Claude for complex tasks, DeepSeek for routine edits, Gemini for prototyping.

Cursor: Agent Mode + Background Tasks

Cursor's agent mode handles multi-file edits within the IDE. It reads your codebase, plans changes, and applies them with your confirmation. Background agents work asynchronously on longer tasks.

Cursor's strength is context awareness. Because it's the editor, it has deep access to your project structure, open files, and recent changes. The AI uses this context to make more relevant suggestions and catch cross-file dependencies.

When Roo Code Wins

VS Code Loyalists

Keep your editor exactly as it is. All extensions, keybindings, themes. No migration. Roo Code lives in the sidebar without changing anything else.

Cost-Sensitive Teams

Free extension + diff-based editing saves 30% on tokens. Use DeepSeek or local models for routine tasks. No $20/month subscription.

Specialized Workflows

Custom modes let you define AI personas with scoped tool permissions. Security reviewers that can't write code. Architects that can't execute commands. The Mode Gallery has community presets.

Model Freedom

Any model, any provider, including local models via Ollama. Switch providers without changing tools. No credit system or premium request limits.

When Cursor Wins

Raw Speed

Cursor completes tasks in roughly half the time. Tab completion is instant. Inline editing feels native. The AI-first architecture removes latency between thinking and executing.

Tab Completion

Cursor's autocomplete predicts multi-line completions as you type. This is the feature developers use hundreds of times per day. Roo Code has no equivalent.

Inline Editing (Cmd+K)

Highlight code, describe the change, see it applied instantly. No switching to a sidebar panel. The edit happens right where you're looking.

Polished UX

Every AI feature is designed into the editor. Context windows, model pickers, and agent panels feel cohesive. Cursor's design advantage comes from controlling the full stack.

If you use tab completion hundreds of times per day and value speed above all else, Cursor is worth the $20/month. If you want open-source flexibility, custom agent personas, and cost control with any model provider, Roo Code gives you more for less.

For precise code editing in either tool, Morph Compact Attention improves long-context accuracy. WarpGrep adds fast semantic codebase search as an MCP tool for Roo Code.

Frequently Asked Questions

Is Roo Code really free?

The VS Code extension is free and open source under Apache 2.0. You pay API costs directly to your model provider. Optional Roo Cloud features (Pro at $20/month, Team at $99/month) add cloud agents and collaboration, but the core coding agent is free.

Is Cursor faster than Roo Code?

Yes. In benchmarks, Cursor completes the same tasks in roughly half the time. Its AI is deeply integrated into the editor, making completions and edits more responsive. Roo Code is slower but users report better reliability on large, multi-file changes.

Can I use my own models with Cursor?

Cursor offers a curated set of models (Claude Sonnet 4, GPT-5.4, Gemini) with $20 in credits per month. You cannot bring arbitrary API keys from external providers. Roo Code supports any model accessible via API, including local models through Ollama.

Do I have to leave VS Code to use Cursor?

Yes. Cursor is a separate application (a fork of VS Code). Extensions, settings, and themes generally transfer, but you run a different editor binary. Roo Code is a VS Code extension that works inside your existing installation.

What are Roo Code custom modes?

Specialized AI personas with scoped tool permissions. Five built-in modes (Code, Architect, Ask, Debug, Custom) plus a community Mode Gallery. Each mode restricts which tools the AI can access, preventing accidental changes during planning or review.
