Agno

Agno is an agent development platform that combines an SDK, the AgentOS runtime, and a control plane. It continues the product formerly called Phidata. Developers can build agents and teams, serve them through APIs or MCP, and operate the runtime in their own cloud or local environment.

Key Highlights

• Open-source Python SDK and AgentOS runtime
• Agents, teams, workflows, and structured outputs
• Knowledge, memory, and database-backed sessions
• REST APIs and MCP access to deployed agents
• Control plane for inspecting and operating runs

What Makes It Different

Build, run, and operate are separate layers. AgentOS can serve agents built with Agno or other supported frameworks, while the control plane connects to that runtime. The SDK repository uses Apache 2.0 licensing. Hosted control-plane plans do not replace the developer's own infrastructure or model-provider account.

Features & Capabilities

Define an agent's model, instructions, knowledge, and tools in code. Python functions can become callable tools, while teams and workflows organize tasks across agents. Persistent storage keeps sessions and memory available between requests rather than depending on an in-process conversation.

AgentOS exposes the agents as services through REST and MCP, with runtime features for scheduling, approvals, and durable execution. The control plane provides chat, session inspection, traces, and evaluations. Data remains in the runtime's database, and deployment templates support common container and cloud environments.

User Ratings and Testimonials

Vendor-published customer accounts from Thinqpoint and Key Data praise development speed and documentation. These are specific experiences, not guarantees for every architecture. Evaluate tool failures, state persistence, and restart recovery with the workload your service will actually run.

Pricing & Value

• Free: open-source SDK/runtime and control-plane access to local AgentOS instances.
• Pro: $150/month for one live AgentOS connection and three team seats.
• Enterprise: custom governance and support terms.

Pro add-ons cost $30/month per extra seat and $95/month per extra live connection. A 14-day Pro trial is available. Agno does not meter runtime events on these plans, but model calls and your hosting remain separate costs.
