Agno
Agno suits Python developers who want a compact framework and a runtime they host themselves, rather than a managed agent service. The free tier is unusually complete, since the local control plane is unlimited, and you pay only when you want a live control plane with team access. Teams that prefer graph-style orchestration or a larger plugin ecosystem may find other frameworks more familiar.
Pros
- Apache-2.0 SDK with agents, teams, workflows and 100+ toolkits
- Runtime serves agents over REST, MCP and chat interfaces and runs in your own cloud
- Free plan has no usage caps or retention limits on the local control plane
- Large open-source community, with over 40,000 GitHub stars
Cons
- The live control plane starts at $150 a month before add-ons
- Heavy rebranding history means older tutorials show Phidata imports and APIs
- SAML SSO is a $300 a month add-on and custom RBAC is Enterprise only
