Key Insights

Breakout
LangGraph: the breakout framework of 2025

LangGraph adoption surged 890% year-over-year, driven by production teams demanding stateful, cyclical workflows that simpler chain-based frameworks cannot support. It is now the fastest-growing framework by relative growth rate.

Fast-growing
CrewAI overtook AutoGen as the number two multi-agent choice

CrewAI's 340% YoY growth pushed it past AutoGen for the second spot among multi-agent orchestration frameworks. Its opinionated role-based API lowered the barrier for teams new to agentic patterns.

Growing
n8n is the leading no-code / low-code option

n8n grew 65% YoY and is the top choice for self-hosted workflow automation, reflecting strong demand from operations and RevOps teams that want agent power without deep Python expertise.

Stable leader
LangChain holds at 62% adoption despite rising competition

LangChain remains the dominant framework by absolute adoption share, used by 62% of indexed agencies. However, its YoY growth has normalised to 18% as specialised frameworks capture incremental demand.
