| Tagline | One API, every model. Pay-as-you-go, no subscriptions. | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | VS Code fork that made AI coding actually work. | AI search done right. Cited answers, not chat theater. |
| Category | dev platform | coding | coding | research |
| Pricing | Pay per token — model-dependent | Part of Claude Pro/Max/Team plans | Free + $20/mo Pro + $40/mo Business | Free + $20/mo Pro |
| Best for | Developers experimenting across models. Apps that want fallback logic. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | Developers.

| Kai's verdict | S-tier for model-shopping. I use this for every prototype before committing. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
