Agentic harnesses

Compare Cursor, Claude Code, Lovable and more

This category includes terminal agents, editor-native tools, browser workspaces, and hybrid assistants. The surface changes the workflow as much as the model does.

This section compares harnesses — the products and operating surfaces around the model. Some are agentic, some are assistive, and browser builders such as Lovable sit here because they turn a brief into working software. Compare models for the APIs behind them, or New models for what launched recently.
