When you’re coding, the tools you use don’t just speed things up—they shape how you think, what you trust, and how much control you really have. This benchmark isn’t about which AI writes the most lines of code fastest. It’s about who lets you work the way you want to—without giving up ownership of your process, your data, or your decisions.
Claude Code and GitHub Copilot are powerful assistants, offering seamless suggestions and automation built into your IDE. But they operate in the cloud, behind closed doors, with fixed pricing and limited visibility into how or why they make their choices.
Cline is different. It runs locally. It doesn’t charge you a subscription—it passes through the exact cost of the model you choose. You see every token, every command, every change in a full audit trail. It doesn’t auto-apply anything. It waits for you. And it lets you bring in any model, any tool, any terminal command—even offline.
This benchmark helps you ask: Do you need an assistant that predicts your next line? Or an agent that respects your judgment, your environment, and your right to know exactly what’s happening? Look for transparency. Look for control. Look for the tools that adapt to your workflow—not the other way around.
