Agno (formerly Phidata) – Open-Source Agent Platform & Framework | Quasa.io

#Quasa #QUA #Agno

Agno (formerly Phidata) is an open-source agent platform: SDK for agents, teams, and workflows; AgentOS runtime you host; Control Plane to watch live runs. Official pricing: Free—framework, local AgentOS, local control plane, community support. Pro—$150/month—hosted control plane to one live AgentOS, 3 seats included then $30 each, extra live connections $95 each, SAML SSO $300 add-on. Enterprise is custom (self-hosted plane, SLA, dedicated lead). Runtime and serving are not metered by Agno; you still pay your LLM APIs and cloud. Students and startups under $2M funding can get Pro free. It is not LangSmith-by-the-trace and not a hosted agent SaaS. Stay on Free until you run production AgentOS. Buy Pro when you need one live connection and a team UI.

𝐂𝗢𝗥𝗘 𝗦𝗧𝗥𝗘𝗡𝗚𝗧𝗛𝗦
• Apache-2.0 SDK and runtime
• Model- and infra-agnostic
• No per-event or storage meter from Agno
• Agents, teams, workflows as primitives
• MCP / ChatGPT / Claude serving paths  

𝗜𝗗𝗘𝗔𝗟 𝗙𝗢𝗥
Python teams who want to own compute and only pay for a control plane when agents go live.

𝗛𝗜𝗚𝗛𝗟𝗜𝗚𝗛𝗧𝗦
• Claims very fast agent instantiation vs LangGraph
• 100+ toolkits
• Approvals, traces, evals in the plane
• SOC 2
• Live public demo OS  

𝗣𝗢𝗧𝗘𝗡𝗧𝗜𝗔𝗟 𝗖𝗢𝗡𝗦𝗜𝗗𝗘𝗥𝗔𝗧𝗜𝗢𝗡𝗦
• You still run (and pay) the boxes
• LLM bills are separate
• Extra connections add up
• Not a no-code agent shop
• Name change from Phidata still confuses search  

𝗢𝗩𝗘𝗥𝗔𝗟𝗟 𝗩𝗘𝗥𝗗𝗜𝗖𝗧
4.5/5 stars. Build locally on Free first. Pay $150 only when a production AgentOS needs a shared control plane—not when you are still in a notebook. Earn 1 QUA reward by reviewing on Quasa.io too!
