Orchestration for Python
Orchestration tools that run on Python. The Catch for each, not a winner list.
3 tools · the Catch, not a ranking
- HaystackProduction NLP pipelines from deepset
Haystack strength is also its constraint. The framework assumes pipeline-based architectures; more exotic agent patterns require workarounds.
- LiteLLMMIT OpenAI-compatible gateway to 100+ LLMs; Enterprise SSO paid
Vs OpenRouter/provider SDKs: self-host gateway you operate — not a hosted model marketplace. LOUD: enterprise/ tree and SSO/audit/RBAC are commercial; core proxy stays MIT. You still pay model providers.
- smolagentsApache-2.0 minimal code-agent framework from Hugging Face
Minimalist — not Temporal durable workflows or production multi-tenant agent platform. Code execution needs sandbox discipline. Vs CrewAI/PydanticAI: HF Hub gravity, less enterprise packaging. You own evals, memory, and deploy.
