agno vs langchain
langchain is much bigger: 145.7k stars against 42.1k. Over the days we have tracked them agno moved +2.1% and langchain +2.6%, so langchain is growing faster right now.
They split the axes: agno leads on noise control, langchain on setup ease.
Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
Where they stand today

Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | agno | langchain |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Diff only | ●●●●● Diff/file only |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● Human approval | ●●●●● None mentioned |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Configurable SDK | ●●●●● Config & prompts |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Self-hostable | ●●●●● Cloud-key usage |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● Multiple providers | ●●●●● Multiple providers |
Setup ease What it takes to get a first useful run out of it. | ●●●●● Quickstart (Docker) | ●●●●● One-command start |
Which one to pick
Pick agno if…
Privacy-first — own and run your agent stack (AgentOS) with self-hosted storage, JWT RBAC, human approval, and observability.
- Noise control: Human approval (4/5 against 1/5)
Pick langchain if…
Model interoperability — Swap providers and integrations easily to prototype and productionize LLM applications with minimal code changes.
- Setup ease: One-command start (5/5 against 3/5)
