|---|---|---|---|---|
| Tagline | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration. | Alibaba's open chat model. Multilingual + agentic. | VS Code fork that made AI coding actually work. |

| Best for | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | Teams with GitHub already. Devs who don't want to change IDEs. | Vietnamese/Chinese content, SEA multilingual use, developers wanting open-weight tool-use. | Developers. Non-developers who want to ship working code. |

| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
