Agno

Developers who want to build their own AI agents without being tied to one model vendor are the people Agno is made for.

Agno is an open-source AI agent library that lets you build, ship and monitor agents that work with any LLM provider.

It is described as lightweight, fast and scalable, and it supports memory, knowledge and tool integration, so an agent can remember context, draw on reference material and call external tools.

Because Agno is model agnostic, switching providers does not mean rewriting your agent from scratch.

That matters if you expect to compare models or change your mind later.

Agno requires technical expertise to set up and use, so it is a code-first framework rather than something a non-developer can pick up in an afternoon.

Monitoring and optimization features are still marked as coming soon.

Manual cloud deployment may also need extra configuration on your side.

If you are comfortable in code and want control over how your agents are put together, Agno is a sensible place to start.
