| Tagline | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | Codeium's agentic IDE. Cascade agent + strong free tier. | Open-source VS Code agent. Reads + writes + runs. | Kuaishou's video model. The surprise standout. |
| Category | coding | coding | coding | video |
| Pricing | Part of Claude Pro/Max/Team plans | Free + $15/mo Pro | Free (open source) + your API costs | Credit-based, free trial |
| Best for | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | Developers who want Cursor-like power for less money. | VS Code users who want agentic coding without changing IDEs. | Anyone who wants top-tier video quality for less. |

| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. Close second to Cursor. If $5/mo matters, start here. | A-tier. Best free agentic option in VS Code. Use with Claude for best results. | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. |
