Haystack by deepset vs. Hookdeck

Haystack is deepset's open-source Python AI orchestration framework for building customizable, production-grade AI agents and workflows. Connect components like language models, vector databases, and file converters into pipelines and agents that retrieve, reason, and act on your own data; use hooks to control the agent loop: enforce a token budget before the next LLM call, incorporate human approval before a risky tool call, or use compaction to keep context small.

Hookdeck is a fast and reliable event gateway for receiving, processing, and delivering asynchronous messages. It centralizes and streamlines communication between services – external providers (e.g. Shopify), internal endpoints (e.g. APIs), and any combination thereof. Configure Hookdeck platform resources and features such as event routing, filters, and transformations. And let Hookdeck automatically retry failed events for painless error recovery. Our developer tooling enables teams to build, deploy, operate, and observe their event-driven applications with confidence.
