Adopt

Proven, recommended for production use

LangGraph↑

State machine approach to multi-agent coordination has become the industry standard for complex agent topologies. Production-ready with strong observability tooling.

Find LangGraph agencies →
LlamaIndex→

Document processing and RAG workflows are where LlamaIndex truly shines. Massive ecosystem, production deployments at scale across all industries.

Find LlamaIndex agencies →
n8n↑

For no-code and low-code automation teams, n8n now rivals Zapier with superior AI integration depth. Best choice when Python expertise is limited.

Find n8n agencies →

Trial

Worth pursuing in proofs of concept

CrewAI↑

Role-based multi-agent collaboration model is intuitive and has strong community adoption. Still maturing in production stability but trajectory is strong.

Find CrewAI agencies →
AutoGen→

Microsoft's backing and research pedigree make it worth trialing for enterprise multi-agent scenarios, but production hardening is still needed.

Find AutoGen agencies →
Anthropic Claude API↑

Claude 3's superior instruction-following and longer context makes it a serious production LLM choice, especially for document-heavy workflows.

Assess

Explore with the intention of understanding the impact

Haystack→

Enterprise search and RAG specialist with strong NLP roots. Best fit for teams with heavy document retrieval needs and European data residency requirements.

Find Haystack agencies →
OpenAI Assistants API→

Managed agent hosting reduces ops burden but creates deep vendor lock-in. Worth assessing for rapid prototyping, evaluate carefully for production.

Find OpenAI Assistants API agencies →
Semantic Kernel↑

Microsoft's enterprise-focused orchestration framework. Growing adoption in .NET shops but Python ecosystem lags. Watch for enterprise integrations.

Find Semantic Kernel agencies →

Hold

Use with caution — limitations outweigh benefits

Raw GPT Function Calling↓

Without orchestration layer, raw function-calling agents are brittle and hard to debug. Always use an orchestration framework above this layer.

Custom Agent Frameworks↓

Building your own orchestration framework from scratch is expensive to maintain and isolates you from ecosystem improvements. Use established frameworks.
