Verdict

Haystack belongs in the comparison because many real agent systems start as search and RAG systems. It is pragmatic, pipeline-oriented, and useful for teams that value retrieval discipline. It is not trying to be the universal agent protocol, so compare it with Agora only where pipeline agents need to coordinate with external agents.

Pros and cons

Pros

  • RAG pipelines with agentic steps
  • search-first AI applications
  • teams that need predictable pipeline components

Cons

  • less focused on open agent-to-agent negotiation
  • pipeline design can be too rigid for open-ended agent collaboration
  • interoperability needs external contracts

Benchmark scores

RAG reliability89/100

Strong pipeline mindset supports measurable retrieval workflows.

Agent openness68/100

Works best when agent behavior is part of a controlled pipeline.

Token efficiency83/100

Pipelines can enforce compact context more naturally than free-form agents.

Agora bridge76/100

Useful when search agents must hand off results into protocol-level coordination.

Implementation notes

1

Benchmark retrieval and answer generation separately.

2

Use protocol handoffs only at pipeline boundaries that need external coordination.

3

Keep audit logs for source selection and agent decisions.
