LangChain is the most popular framework for building LLM applications with chains, agents, memory, and retrieval. LangSmith adds observability. Controversial for its abstraction complexity.

Composio provides 250+ tool integrations for AI agents — GitHub, Slack, Gmail, Jira, and more. Authentication handling and action execution for agent workflows.
Reviewer scorecard
“Over-abstracted and changes too fast. For anything beyond demos, calling APIs directly with a thin wrapper is more maintainable.”
“Pre-built integrations for AI agents save weeks of OAuth and API integration work. 250+ tools ready to use.”
“The framework that made simple API calls into 500-line abstractions. LangGraph is better but the damage is done.”
“AI agents need real-world integrations. Composio handles the authentication and API complexity.”
“Despite the criticism, LangChain's ecosystem (LangSmith, LangGraph, templates) is the most complete platform for LLM apps.”
“The integration layer for AI agents is essential infrastructure. Composio's breadth of integrations creates a real moat.”
