Cursor S | Claude Code S | Manus S | OpenRouter S | |
|---|---|---|---|---|
| Tagline | VS Code fork that made AI coding actually work. | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | Autonomous AI agent that actually finishes tasks. | One API, every model. Pay-as-you-go, no subscriptions. |
| Category | coding | coding | agents | dev platform |
| Pricing | Free + $20/mo Pro + $40/mo Business | Part of Claude Pro/Max/Team plans | Free tier + $39-$199/mo | Pay per token — model-dependent |
| Best for | Developers. Non-developers who want to ship working code. | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | People who want to hand off tasks entirely — trip planning, research, spreadsheet building. | Developers experimenting across models. Apps that want fallback logic. |

| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier in the agent category. The first one I'd give to a non-technical friend. | S-tier for model-shopping. I use this for every prototype before committing. |
