What Is Fleet?
Fleet is the no-code layer on top of Agent Server. Where create_agent and create_deep_agent require Python code, Fleet lets you build and deploy agents entirely through a web UI. Select a template, configure the model and tools, connect channels (Gmail, Slack), and schedule runs — all without writing code.

| Fleet (no-code) | None | Templates + configuration | Business users, quick prototypes, ops automation |
| create_agent (code) | Python/JS | Full programmatic control | Developers, custom logic, production agents |
| create_deep_agent (code) | Python/JS | Full + planning/filesystem | Complex autonomous tasks, coding agents |
