Decision Guide by Team Size
Solo Developer
Start with OpenAI Agents SDK if using OpenAI models, or Agno for multi-model support. Both have minimal setup. Add Dify if you prefer visual building.
Small Team (2-10 engineers)
CrewAI for role-based multi-agent systems, or LangGraph for fine-grained control. Mastra if you are a JS shop.
Enterprise (50+ engineers)
LangGraph + LangSmith for observability and governance, or Hermes for an integrated platform approach. Consider Dify for business teams needing self-service.
Key Trends in 2026
- Python vs TypeScript: The market is bifurcating. LangGraph, CrewAI, Agno for Python. Mastra for TypeScript.
- Structured outputs: Every framework now supports structured JSON outputs. Pydantic AI and Agno lead here.
- Memory: The biggest differentiator in 2026. Agno and Hermes are building sophisticated memory systems.
- No-code matures: Dify proves non-technical teams can build capable agents.
- Safety and governance: LangGraph human-in-the-loop, OpenAI guardrails, Hermes skill-based permissions.
