Cursor vs Cline: IDE vs Extension — Which AI Coding Tool Is Right for You?
Cursor vs Cline: full comparison of the AI IDE vs the VS Code extension. Pricing, privacy, model support, agent capabilities, and reliability — so you can pick the right tool for your workflow.
| Feature | Cursor | Cline |
|---|---|---|
| Type | Standalone IDE (VS Code fork) | VS Code extension |
| Price | Free / $20 Pro / $40 Business | Free (you pay API costs) |
| AI billing | Included in subscription | Your own API key (pay-per-token) |
| Supported models | GPT-4o, Claude, Gemini (managed) | Any OpenAI-compat API (OpenRouter, Anthropic, Ollama) |
| Privacy | Telemetry by default (opt-out) | Your API key, your data |
| Agent tasks | Composer (file edits + terminal) | Full agentic (browser, MCP tools) |
| Offline / local LLM | Limited (API key mode) | Yes via Ollama |
1. The fundamental difference
Cursor is a standalone IDE that replaces VS Code entirely. It ships with AI built into every layer — Tab autocomplete, Composer agent, inline chat, and codebase indexing. You install Cursor instead of VS Code.
Cline is a VS Code extension installed inside your existing VS Code (or Cursor). It adds a chat-based agentic AI panel without replacing your editor or workflow. Since Cursor is VS Code under the hood, you can actually run Cline inside Cursor to combine both tools.
2. Pricing model
Cursor charges a flat subscription. The Pro plan ($20/mo) includes 500 fast requests per month using GPT-4o or Claude, plus unlimited slow requests. Business ($40/mo) adds privacy mode and team features.
Cline is free software — you pay your AI provider directly at their API rates. Using Anthropic's claude-sonnet-4-6 costs roughly $3/1M input tokens and $15/1M output tokens. For a developer making 100 moderate agent runs per month, real costs often land between $5–$30 depending on context size.
- Heavy users: Cline can be cheaper — you only pay for tokens you actually use, and can route cheap tasks to low-cost models like Groq or local Ollama.
- Light users: Cursor's flat subscription is more predictable — no surprise bills, no API key management.
- Teams: Cursor Business includes centralized billing; Cline requires each developer to manage their own API key and spending.
3. Model flexibility
Cursor supports GPT-4o, Claude 3.5/3.7, and Gemini — but only through their managed platform. You cannot point Cursor at an arbitrary API endpoint or use a model they haven't integrated.
Cline supports any OpenAI-compatible API. This includes:
- Anthropic direct — latest Claude models at standard pricing
- OpenRouter — 50+ models from one API key, including Llama, Mistral, and more
- Groq — extremely fast inference for Llama and Mixtral models
- Ollama — local models running entirely on your machine
- Any self-hosted or custom endpoint — LM Studio, llama.cpp server, Azure OpenAI
This model flexibility is Cline's biggest advantage for power users who want to experiment, cut costs, or use specialized models for specific tasks.
4. Privacy
Cursor collects telemetry by default and your code is sent through their servers for AI processing. Cursor's Privacy Mode (Business plan only) opts you out of training data usage, but your code still passes through Cursor's infrastructure.
Cline sends data directly to your chosen API provider — there is no intermediary. With Anthropic, your data is subject to Anthropic's privacy policy. With a local Ollama model, nothing leaves your machine at all.
5. Agentic capabilities
Cursor's Composer agent can edit multiple files across your project and run terminal commands. It handles refactoring, scaffolding, and multi-step coding tasks well within the IDE context.
Cline goes further with a broader agentic surface:
- Browser automation — Cline can open a browser, navigate pages, and interact with web UIs as part of a task
- MCP tool integration — connect filesystem tools, database clients, external APIs, and custom MCP servers
- Granular permission controls — auto-approve specific actions (reading files) while requiring manual approval for others (executing commands, writing to disk)
- Transparent action log — every file read, shell command, and API call is shown before execution
For developers building agents, automating multi-service workflows, or needing deep tooling integration, Cline's agentic depth is meaningfully superior.
6. Who should use which
Use Cursor if you…
- Want an all-in-one IDE experience out of the box
- Prefer predictable flat-rate subscription pricing
- Don't want to manage API keys or track token costs
- Value polished Tab autocomplete as a primary workflow
- Work in a team with centralized billing (Business plan)
Use Cline if you…
- Want to choose any model (OpenRouter, local Ollama, etc.)
- Have a sensitive codebase requiring air-gapped or private operation
- Need deep agentic tasks: browser, MCP tools, custom APIs
- Are a heavy user who can optimize costs by model-switching
- Already love your VS Code setup and don't want to switch IDEs

FAQ
Can I use Cline inside Cursor?
Yes. Since Cursor is built on VS Code, it supports the full VS Code extension marketplace. Install the Cline extension inside Cursor to get Cline's agentic capabilities and model flexibility while keeping the Cursor IDE. Many developers use both together.
Is Cline really free?
Cline the software is free and open source. You pay your AI provider directly — per token, at the provider's standard rates. Using claude-sonnet-4-6 via Anthropic costs ~$3/1M input tokens. For heavy agentic use with long contexts, costs can add up — routing lighter tasks to Groq or a local Ollama model helps keep bills low.
Which has better autocomplete, Cursor or Cline?
Cursor's Tab autocomplete is significantly more refined for inline suggestions. It predicts your next edit as you type and supports multi-line completions with ghost text. Cline is primarily a chat-based agentic tool — it doesn't provide inline autocomplete at all. If autocomplete is your primary need, use Cursor (or GitHub Copilot).
Does Cline work with local LLMs?
Yes. Cline supports any OpenAI-compatible API, including Ollama running locally. Configure Cline to point at http://localhost:11434 (Ollama's default port) and select your local model. This is the only fully offline, air-gapped option — no data leaves your machine.
