Framework for building agentic apps with memory, tools, and vector DBs.
Phidata (recently rebranded as Agno) is a Python framework for building AI agents with a focus on simplicity and practical production features. Its design philosophy is 'agents should be as easy to build as functions' — and the API largely delivers. You create an Agent, give it a model, tools, instructions, and optional knowledge/memory, and it works.
The framework stands out for its batteries-included approach to common agent requirements. Knowledge bases are first-class: point a PDFKnowledgeBase, WebsiteKnowledgeBase, or JSONKnowledgeBase at your data sources, and Phidata handles chunking, embedding, and vector storage (using PgVector by default). Memory is similarly integrated — agents can store conversation history, summaries, and key facts in a database, maintaining context across sessions.
CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
