Cline is an open-source AI coding assistant for VS Code that features dual Plan/Act modes, terminal execution capabilities, and the Model Context Protocol (MCP) for custom tool creation. It serves as a fully collaborative AI partner for developers.

How is Cline different from GitHub Copilot?

Cline is open-source and offers unique features like Plan/Act modes for structured development, terminal command execution, browser automation for testing, and the Model Context Protocol (MCP) for creating custom development tools.

What programming languages does Cline support?

Cline supports all major programming languages and frameworks through its AI models and can execute terminal commands, edit files, and automate browser testing across different technology stacks.

Why We Built Cline to Never Hold You Hostage

Yesterday, Windsurf users lost access to Claude 3.x models with five days' notice. OpenAI's acquisition of Windsurf created competitive tensions with Anthropic, and developers got caught in the crossfire.

Picture this: you're deep into a critical project, and suddenly your AI coding assistant is crippled by corporate politics. Free tier users lost access entirely; paid subscribers face severe capacity constraints.

This validates why we built Cline differently from day one.

When Corporate Wars Hit Developers

The Windsurf situation reveals what happens when AI giants compete: developers get caught in the crossfire. Anthropic doesn't want valuable interaction data flowing to OpenAI (Windsurf's new owner). This isn't about technical architecture -- it's about competitive intelligence.

Windsurf's CEO put it bluntly: "We wanted to pay them for the full capacity." When corporate acquisitions create conflicts, wanting to pay isn't enough. Your access becomes collateral damage.

Built to Never Restrict Access

The real innovation in AI coding comes from the models themselves -- Claude 4, Gemini 2.5 Pro, GPT-4.1, DeepSeek R1. These are the engines of capability. Tools should be transparent conduits to that power, not gatekeepers.

When we built Cline, we made a fundamental architectural choice: never inhibit the full power of AI models. You use your own API keys, pay providers directly, access models with their full capabilities -- no artificial limits on context, no throttling for business model reasons.

We built Cline so we literally cannot restrict your access to AI models, even if we wanted to.

True Model Agnosticism

This direct connection architecture enables something most platforms can't offer: true model agnosticism. When Claude 5 launches, you'll have access immediately. When the next breakthrough model from Google, OpenAI, or an open-source project emerges, you can use it on day one. And what will happen to Cline? It will get better, immediately.

No waiting for your platform to negotiate partnerships. No wondering if your tool will support the latest models. No risk of being cut off when corporate relationships sour.

Your connection to AI innovation flows directly through Cline, not around it.

Open Source: Your Safety Net

Open source provides an additional layer of protection. When platforms change direction, get acquired, or shut down, users are left stranded. Open-source tools like Cline belong to the community. Even if our company disappeared tomorrow, Cline would continue to evolve.

The Windsurf situation won't be the last. As AI companies consolidate and compete, more developers will lose access to models they depend on. The solution isn't hoping for better corporate relationships – it's building tools that can't be used as weapons in AI company wars.

The Real Cost of Vendor Lock-in

The AI coding space is moving toward consolidation, with major players acquiring tools to create closed ecosystems. This might seem convenient in the short term, but it comes with hidden costs:

Restricted model access: You're limited to whatever models your tool company provides
Artificial constraints: Context limits and capability restrictions to fit subscription models
Vulnerability to corporate politics: Your tools can become pawns in larger competitive battles
Innovation delays: You have to wait for your tool company to integrate new capabilities

Cline's approach eliminates these risks. You control your AI destiny.

What This Means for You

If you're a Windsurf user dealing with restricted Claude access, or any developer concerned about AI tool independence, Cline offers a different path:

Immediate access to Claude 4, Gemini 2.5 Pro, DeepSeek R1, and any other model you choose
Full transparency into every AI interaction
No artificial restrictions on context windows or model capabilities
Works where you already work: Use Cline within VS Code, Cursor, or even Windsurf itself
Future-proof architecture that adapts to new models automatically
Open-source foundation that ensures community-driven innovation
Enterprise-grade security: Your data never passes through our servers with BYOK

For displaced Windsurf users specifically: Cline supports Windsurf rules files, so migrating your existing configurations is straightforward. You can continue using your familiar IDE while gaining the independence and transparency that corporate politics can't touch.

The Future Belongs to Independence

We're entering an era where AI capabilities will define competitive advantage in software development. The tools that unlock this potential shouldn't be subject to corporate politics or acquisition dynamics.

Cline was built on the principle that developers deserve unmediated access to the most powerful AI available. Yesterday's events with Windsurf validate this approach – and remind us why independence matters.

The next breakthrough model is coming. When it arrives, Cline users will be ready.
