AutoGen (AG2) alternatives in detail
CrewAI
open sourceMITSDKCrewAI orchestrates multiple agents as a 'crew' with roles, goals, and tasks — a high-level, fast-to-start abstraction for collaborative multi-agent work. It also offers Flows for event-driven, more deterministic control when you need it. Standalone and independent of LangChain.
LangGraph
open sourceMITSDKLangGraph models an agent as an explicit state graph of nodes and edges, trading some abstraction for control. Its built-in persistence (checkpointing), human-in-the-loop interrupts, and streaming make it a common choice for production agents that need to be debuggable and resumable.
OpenAI Agents SDK
open sourceMITSDKOpenAI's open-source Agents SDK is a small, unopinionated framework for building agents: a core agent loop plus handoffs (delegation between agents), guardrails (input/output validation), sessions (memory), and built-in tracing. The production-grade successor to Swarm; works with non-OpenAI models too.
Agno
open sourceApache-2.0SDKAgno (formerly Phidata) is a Python framework for building multi-agent systems with memory, knowledge, and tools. You compose Agents, Teams, and Workflows over 20+ model providers, and can run them in production with the AgentOS runtime. The core library is open source under Apache-2.0.
Claude Agent SDK
freeSDKThe Claude Agent SDK is a toolkit for building custom AI agents on the same harness that powers Claude Code. Official Python and TypeScript SDKs expose the core agent loop — reading files, running commands, calling tools, iterating on feedback — as a programmable library, with MCP support, configurable permissions, streaming, and multi-turn sessions.
Google ADK
open sourceApache-2.0SDKGoogle ADK (Agent Development Kit) is an open-source, code-first framework for building, evaluating, and deploying AI agents in Python (Java also available). It's model-agnostic and deployment-agnostic — run agents locally, on Cloud Run, or in Vertex AI Agent Engine, which it powers.
