Agentic Index
Agno vs LangChain (2026)
Choose Agno for a lighter, faster Python agent runtime and choose LangChain when ecosystem coverage and mature tooling outweigh framework weight. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Agno is Apache 2.0 with plans from 150 dollars a month and a free tier, while LangChain's LangSmith runs from 39 dollars a seat a month with a free tier. Teams that find LangChain heavy often land on Agno; teams that need every connector prebuilt rarely regret the incumbent.
On the Agentic Index agent infrastructure ranking, Agno clears the bar and LangChain does not. Agno documents all five production contract capabilities in full; LangChain does not document security and identity governance in full, nor observability and auditability. 34 of the 186 vendors in the lane clear it.

This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Agno and LangChain are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 956 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Agno if
- Runtime performance and a small dependency surface matter for your deployment
- You want built in memory and multi agent support without extra packages
- Self hosting under Apache 2.0 is your default posture
Choose LangChain if
- Integration breadth across tools and providers shortens delivery more than raw speed
- LangSmith tracing is already how your team debugs LLM systems
- Graph based orchestration via LangGraph fits your workflow complexity
