Show HN: Agno – A full-stack framework for building Multi-Agent Systems

Summary

What is Agno? Agno is a full-stack framework for building Multi-Agent Systems with memory, knowledge and reasoning. Use Agno to build the 5 levels of Agentic Systems: Level 1: Agents with tools and instructions. Level 2: Agents with knowledge and storage. Level 3: Agents with memory and reasoning. Level 4: Agent Teams that can reason and collaborate. Level 5: Agentic Workflows with state and determinism. Example: Level 1 Reasoning Agent that uses the YFinance API to answer questions: from agno . agent import Agent from agno . models . anthropic import Claude from agno . tools . reasoning import ReasoningTools from agno . tools . yfinance import YFinanceTools reasoning_agent = Agent ( model = Claude ( id = "claude-sonnet-4-20250514" ), tools = [ ReasoningTools ( add_instructions = True ), YFinanceTools ( stock_price = True , analyst_recommendations = True , company_info = True , company_news = True ), ], instructions = "Use tables to display data." , markdown = True , ) reasoning_finance_agent.mp4 Get Started If you're new to Agno, read the documentation to build your first Agent, chat with it on the playground and monitor it on agno.com. After that, checkout the Examples Gallery and build real-world applications with Agno. Why Agno? Agno will help you build best-in-class, highly-performant agentic systems, saving you hours of research and boilerplate. Here are some key features that set Agno apart: Model Agnostic : Agno provides a unified interface to 23+ model providers, no lock-in. : Agno provides a unified interface to 23+ model providers, no lock-in. Highly performant : Agents instantiate in ~3μs and use ~6.5Kib memory on average. : Agents instantiate in and use memory on average. Reasoning is a first class citizen : Reasoning improves reliability and is a must-have for complex autonomous agents. Agno supports 3 approaches to reasoning: Reasoning Models, ReasoningTools or our custom chain-of-thought approach. : Reasoning improves reliability and is a must-have f...
