LangGraph

Graph-based orchestration library for stateful, multi-step agents with persistence and human-in-the-loop.

+ Explicit state graphs with checkpointing make long-running agents debuggable and resumable.
− Steep learning curve and more boilerplate than simpler agent SDKs.

LangGraph alternatives

All 16 alternatives →
1
smolagents Open source
Minimal Python library for agents that write and execute code as their actions.

+ Code-as-action agents in about a thousand lines of core code that work with any Hub model.
− Running model-written Python needs sandboxing, which is left mostly to you.

2
Vercel AI SDK Open source
TypeScript toolkit for streaming LLM responses, tool calls, and agents across providers and UI frameworks.

+ Unified provider interface and React hooks make streaming chat UIs trivial.
− Major-version upgrades have required significant rewrites.

Goose Open source
Open-source, extensible local AI agent that automates engineering tasks via MCP extensions.

+ MCP-first design means any MCP server becomes a Goose capability with no glue code.
− Less tuned for coding than Claude Code, so results vary widely by model.

4
LangChain Open source
Framework of composable building blocks for LLM apps, with integrations for every model and vector store.

+ Largest integration catalogue of any framework, so almost any provider is one import away.
− Frequent breaking API changes and heavy abstractions make simple things feel over-engineered.

5
Claude Agent SDK Open source
SDK exposing the Claude Code agent loop, tools, and MCP support for building custom agents in Python or TypeScript.

+ Inherits Claude Code's file, shell, and subagent tooling, so agents are production-grade on day one.
− Tied to Claude models and the Claude Code runtime rather than a provider-agnostic design.
