Problem: Claude Code and Cline both run autonomous coding tasks, but they live in different places and bill in different ways. Claude Code is a paid terminal agent. Cline is a free VS Code extension you run on your own API key. The right pick comes down to where you work and how you want to pay.
Both let an agent read files, run commands, and edit code. The difference is the surface and the cost model.

Claude Code runs in your terminal. You give it a goal in plain English and it runs a session: reading the codebase, writing code, running tests, and looping until done. With Opus 4.8 it carries a 1M-token context and scores 88.6% on SWE-bench Verified. It is a managed subscription, so Anthropic handles the model and infrastructure.
Cline runs inside VS Code. It is open-source with over 5 million installs and 61,000+ GitHub stars, adopted by teams at Samsung, Salesforce, and Amazon. It executes multi-step tasks with a human-approval step at each action, so you see and confirm every file write and terminal command. It is free, and you bring your own API key.
| Dimension | Claude Code | Cline |
|---|---|---|
| Type | Managed subscription | Free open-source extension |
| Home | Terminal, desktop, mobile | VS Code |
| Price | From $20/month | $0 + your model usage |
| Model | Claude only | 30+ providers, including Claude |
| Context window | Up to 1M tokens (Opus 4.8) | Depends on the model you choose |
| Approval flow | Autonomous, optional gates | Approval at each step by default |
| Best for | Long unattended sessions | In-editor agentic edits |
Where Claude Code wins
Autonomy at length is the big one. Claude Code is built to run for an hour or more without you. You hand it a feature spec and come back to working code across schema, API, frontend, and tests. Cline's step-by-step approval is great for control but slows down long unattended runs by design.
Context at scale follows. The 1M-token window holds roughly 3,000 files, so large-codebase sessions do not lose track of what they read earlier. Cline's effective context is whatever your chosen model supports, often smaller.
Control beyond the editor matters too. You can start a Claude Code session in the terminal and check on it from claude.ai/code on your phone. Cline lives in your VS Code window. For the full cost picture, see Claude Code pricing.
Where Cline wins
It is free, and that is not a small thing. No subscription, no feature gates. You pay only the tokens you use, and on a local model through Ollama you pay nothing. For builders watching costs, Cline removes the monthly floor entirely.
Model freedom is wide. Cline crossed 30 providers in 2026, from Anthropic and OpenAI to Gemini, DeepSeek, Qwen, Grok, and local models. You can run Claude for hard tasks and a cheap model for routine edits without leaving the tool. Claude Code runs Claude only.
In-editor transparency is the workflow advantage. Because Cline asks for approval at each step and shows every action inline, you stay in full control of what the agent touches. Developers who want to watch and gate every change prefer that to hands-off autonomy. It is also MCP-ready, so you can extend it with custom tools the way you would extend Claude Code with MCP.
Which should you use
| Your situation | Pick |
|---|---|
| You want long, unattended autonomous sessions | Claude Code |
| You want a free agent with no subscription | Cline |
| You work across a large codebase needing 1M context | Claude Code |
| You want to mix and match models | Cline |
| You want desktop and mobile control | Claude Code |
| You want to approve every step inside VS Code | Cline |
| You want managed infrastructure, no API keys | Claude Code |
Many developers run both: Cline for fast, gated, in-editor edits on a cheap model, and Claude Code when a task needs long autonomy or full-codebase context. They complement each other.

FAQ
Is Cline free? Yes. Cline is a free, open-source VS Code extension with over 5 million installs and no subscription. You bring your own API key and pay only for model usage, or run a local model for zero cost. Claude Code is a paid subscription starting at $20/month.
Can Cline use Claude models? Yes. Cline supports more than 30 providers including Anthropic, so you can run it on Claude Opus 4.8 or Sonnet 4.6 with your own API key and pay per token.
What is the difference between Claude Code and Cline? Claude Code is a paid terminal agent with a 1M-token context and long autonomous sessions. Cline is a free, open-source VS Code extension that runs autonomous tasks with approval at each step. Claude Code favors hands-off autonomy; Cline favors in-editor control and zero subscription cost.
Which is better for large projects? Claude Code, when the project needs full-codebase context. Its 1M-token window holds far more than most models Cline runs on. For smaller, gated edits inside VS Code, Cline is excellent and free.
