Cline, The Jouster's Review 2026

The Essentials in 20 Seconds

• Open source code agent for VS Code, multi-model, terminal and file system access
• Price: free (open source), you only pay for API tokens
• Joute score: 8.0/10
• Obsolescence risk: 7/10
• Who it's for: VS Code developers who want a powerful agent without a fixed subscription

Verdict: Cline is the best free VS Code extension for agentic use. Less polished than Cursor, but more open and without lock-in.

What Is Cline

Cline is an open source VS Code extension that turns the editor into a complete agentic environment. The agent can read and write files, run commands in the terminal, browse the web, and use any LLM via an API key.

Launched under the name Claude Dev then renamed Cline, the project exploded in popularity during 2025 with the rise of agentic models. In 2026 it surpasses 30,000 stars on GitHub and has a plugin ecosystem (MCP servers) that extends its capabilities.

What Works

Full System Access

Unlike Copilot or Codeium, Cline can read any file in your project, run shell commands, install dependencies, and even open a browser to check rendering. It's a real agent, not a completion assistant.

MCP Support

Cline supports the Model Context Protocol, which lets it connect to databases, APIs, and design tools via third-party MCP servers. The ecosystem is growing fast.

Total BYOK

You plug in your Anthropic, OpenAI, Gemini, Mistral or local model key. You choose the right tool for each task: a fast, cheap model for small tasks, a powerful model for major projects.

Transparency

Cline shows exactly which files it's reading, which commands it wants to run, and asks for confirmation before acting. You stay in control at every step.

What Doesn't Work as Well

Less Polished Than Cursor

Cursor has a more polished product, better autocomplete, and more cohesive UX. Cline is still an extension, not a rethought IDE.

Cost Can Surprise You

Without discipline on model choice, tokens accumulate fast on a long session. You need to understand API costs to avoid surprises.

Stability

Being open source and in rapid development, regressions appear between versions. Nothing blocking, but less guarantee than a commercial product.

Comparison Table

Pricing

• Cline: free, open source (Apache 2.0)
• Real cost: tokens from your chosen API, estimated between $5 and $50/month depending on usage

Who It's For

Yes for: agentic engineers who want a powerful agent in VS Code without a fixed subscription. Profiles who already use LLM APIs and want to leverage them.

No for: beginners looking for a turnkey experience. Those who prefer a fully managed product without configuration.

Karpathy Obsolescence Risk

Score: 7/10. Cline is open source, which gives it a lifespan independent of any company. The risk is that VS Code or Cursor natively integrate the same capabilities, making the extension redundant. MCP support is a differentiating advantage that slows this risk.

Final Verdict

Cline is the choice for developers who want agent power without paying $18/month. It's less comfortable than Cursor, but more flexible and more transparent. For an agentic engineer with their own API keys, it's hard to beat on value.

Joute score: 8.0/10.

FAQ

Is Cline really free?

The extension is free and open source. You pay for the connected LLM API's tokens. With moderate use on Claude Haiku, the monthly cost is often under $10.

Cline vs Cursor, which to choose?

Cursor for the smoothest experience and Tab autocomplete. Cline for total control, BYOK, and no fixed subscription.

Does Cline work with local models?

Yes, via Ollama or LM Studio. Performance depends on the chosen local model.

What is MCP support in Cline?

The Model Context Protocol lets Cline connect to external servers (databases, APIs, design tools) to extend its capabilities beyond just code.
