LangGraph alternatives
LangGraph is a low-level graph runtime for stateful agents. People look for alternatives when they want ready-made agent abstractions instead of graphs, a different language, a different vendor's cloud, or no paid deployment product in the picture. The alternatives below are tools in this directory; each reason comes from the two tools' records. Data as of 2026-09-30.
- CrewAI: Supplies roles, tasks and sequential or hierarchical processes instead of graphs, with Flows for deterministic steps and A2A in the library. See LangGraph vs CrewAI. (comparison)
- Microsoft Agent Framework: Also graph workflows with checkpoints per superstep, in Python and .NET, with first-party MCP, A2A and AG-UI packages and five built-in orchestrations.
- Google ADK (Python): ADK 2.0 has a
Workflowgraph plus coordinator agents, a CLI, dev web UI and eval runner, with a deployment path on Google Cloud. Tool confirmation and A2A are experimental. (comparison) - OpenAI Agents SDK (Python): A smaller model: agents, handoffs, guardrails, sessions and tracing run by a
Runner, without step-level checkpoints. A2A is recorded as no. (comparison) - Pydantic AI: Typed agents with validated outputs, deferred tools for approvals and durable execution on external engines; graph flows use the separate
pydantic-graphpackage. - Mastra: For TypeScript teams: supervisor agents and typed workflows with suspend and resume, MCP and A2A. LangGraph.js is the same-vendor alternative in TypeScript.
