Developer Documentation
Agno provides a well-structured developer experience across its two core products:
Agent Framework (Open Source)
- Install via pip and define agents in Python with a clean, minimal API
- Supports sync and async execution with a unified agent interface — no event loop headaches
- Build individual agents, teams of agents, tools, and workflows
- Connect agents to UIs, Telegram, Slack, WhatsApp, and more
AgentOS Runtime
- API Layer: 50+ REST endpoints (OpenAPI/SSE) for runs, sessions, memory, knowledge, and traces — available instantly when you connect an agent
- Auth & Isolation: JWT-based RBAC, per-user and per-request isolation, stateless architecture for horizontal scaling
- Governance: HITL approval flows, admin approval gates, post-execution hooks, and full audit trail stored in your own database
- Observability: Structured tracing exported to your existing tools; session and interaction monitoring via the AgentOS UI
- Compatibility: Works with Agno SDK, Claude Agent SDK, LangGraph, DSPy, or custom homegrown agent systems
- BYOC: Deploy to AWS, GCP, Railway, or fully airgapped environments — no data leaves your cloud
