What Haystack is
Haystack is an open-source AI orchestration framework for developers building agents, multimodal applications, advanced retrieval-augmented generation systems, and scalable search. Applications are assembled as modular pipelines from components such as retrievers, routers, memory layers, tools, evaluators, and generators. Pipelines can run on your own infrastructure and be served as REST APIs or MCP servers with Hayhooks. The integrations directory lists 189 integrations across model providers, vector databases, monitoring tools, and community components, including OpenAI, Anthropic, Amazon Bedrock, Elasticsearch, Pinecone, and Datadog. The separate Haystack Enterprise Platform adds a visual pipeline builder, debugging, templates, data indexing, a playground, prompt exploration, deployment, and monitoring. It can run on managed cloud or self-hosted infrastructure and exposes a REST API. Its listed provisions include SOC 2 Type II, ISO 27001, GDPR, HIPAA, CSA Star Level 1, RBAC, audit logs, traces, guardrails, and SSO. A free Enterprise trial is available by form request and includes cloud infrastructure for building and testing prototypes.
