Open source AI orchestration framework for building production ready LLM applications with modular pipelines and agents in Python.
Every pairing below carries a compatibility record backed by an evidence page: the package, docs page, or MCP path that proves the connection. Pairings are grouped by connection type first, because that decides how much integration work you own. A tool missing here is unverified by AgentsUse, not incompatible. Read the Haystack profile for setup and scope before choosing.
This hub lists 3 verified pairings. AgentsUse keeps hubs out of the search index until at least five tools have verified compatibility, so thin lists never masquerade as complete coverage.
Official adapters
Adapter packages published by the framework vendor or the tool vendor for this pairing.
Start from the job, not the framework: find the tool whose limitations you can live with, then check how it connects. Native and official adapter paths usually mean the pairing is maintained by someone whose roadmap you can read. Community adapters and API-only options shift the maintenance to your team. When two tools both fit, prefer the one whose integration page shows a configuration you can run unchanged, and keep a person reviewing the first outputs the pairing produces.
