Framework for building agentic apps with memory, tools, and vector DBs.
Build AI assistants that can search the web, query databases, and use tools — like creating custom ChatGPT-style agents for your business.
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.
Phidata's tool system is straightforward. Tools are Python functions with the right signatures, and the framework ships with built-in tools for web search (DuckDuckGo, Google), code execution, file I/O, email, and financial data (YFinance). Structured outputs are supported through Pydantic model specification on the agent.
The multi-agent support uses a 'team' concept where agents can delegate to other agents. A team leader routes tasks to specialists and synthesizes results. It's simpler than CrewAI's crew model but covers common delegation patterns.
Phidata includes a playground (web UI) for testing agents interactively and monitoring sessions. Deployment is supported through Agno Cloud or self-hosted via Docker.
The honest take: Phidata's strength is speed from zero to working agent. If you want a Python agent with RAG, memory, tools, and structured outputs running in 20 minutes, Phidata gets you there faster than most alternatives. The tradeoff is less flexibility for complex orchestration. It's intentionally opinionated, which makes simple things simple but complex things harder. For teams that need practical agents that 'just work' with common tools and data sources, Phidata is an excellent choice.

Phidata (now Agno) offers a pragmatic, Pythonic approach to building agents with built-in tools and memory. Great for getting agents running quickly, though less flexible than LangGraph for complex orchestration.
Pre-built classes for PDFs, URLs, JSON, CSV, text files, and databases. Handles document loading, text extraction, chunking, embedding, and vector storage automatically using PgVector.
Use Case:
Building a support agent that answers questions from product documentation by pointing a PDFKnowledgeBase at product manuals.
Database-backed memory storing conversation history, generating summaries of past interactions, and extracting key facts. Agents recall previous conversations across sessions.
Use Case:
Creating a personal assistant that remembers user preferences, past requests, and conversation context across multiple sessions.
Specify a Pydantic model as the agent's response_model, and outputs are automatically parsed and validated. Supports nested models, lists, and custom validators.
Use Case:
Building a data extraction agent that pulls structured info (company name, revenue, employee count) from news articles into typed Python objects.
Multi-agent architecture where a team leader coordinates specialists, delegating subtasks and synthesizing results. Each member can have different models, tools, and knowledge bases.
Use Case:
Creating a research team where a coordinator delegates web research, data analysis, and report writing to separate specialist agents.
Ships with tools for DuckDuckGo search, Google search, YFinance financial data, ArXiv papers, Wikipedia, email, code execution, file operations, and SQL queries.
Use Case:
Building a financial analysis agent that uses YFinance for stock data, DuckDuckGo for news, and code execution for analysis scripts.
Web-based UI for testing agents interactively, viewing conversation histories, monitoring sessions, and debugging tool calls. Agents can be shared for collaborative testing.
Use Case:
QA testing an agent before deployment by running interactive sessions in the playground and reviewing tool call logs.

We believe in transparent reviews. Here's what Phidata doesn't handle well:
Agno is the new name for Phidata — the project rebranded in 2025. The core framework is the same, but the package is transitioning from 'phidata' to 'agno'. Both package names currently work, but new projects should use Agno.
PostgreSQL with pgvector is recommended for full features. For quick prototyping, use in-memory storage or SQLite. The full feature set (persistent memory, knowledge bases) works best with PostgreSQL. Docker commands are provided to spin up pgvector quickly.
Phidata is more opinionated and faster to start — working agents with RAG and memory in fewer lines. LangChain is more flexible with more integrations. Choose Phidata for batteries-included experience; choose LangChain for extensive customization or graph-based orchestration.
Yes. Phidata agents can be served as REST APIs using FastAPI (built-in support). The framework generates API endpoints with streaming support. Deploy via Agno Cloud, Docker, or any container platform.
