Web Data and Document Extraction
Use Firecrawl with Haystack
Firecrawl connects to Haystack through a official adapter package path (FirecrawlWebSearch). This page records what that connection looks like and links the evidence behind it.
AgentsUse publishes this page for readers but keeps it out of the search index until the pairing carries a configuration example checked against the source.
Pairing facts
Why this pairing
A web data API that searches, scrapes, and crawls sites into clean markdown and structured output for AI agents.
Best for: Agents and pipelines that need clean markdown or structured JSON from many pages without running browsers themselves.
Not ideal for: Fully local, no-account workflows. The practical path is the hosted API, and the open-source stack is a larger self-host than a single library install.
Evidence
Haystack WebSearch documentation lists FirecrawlWebSearch as a search engine using the Firecrawl API, alongside TavilyWebSearch and BraveWebSearch.

Compatibility here means the cited page documents the pairing. It does not mean AgentsUse benchmarked the combination or that every version works unchanged. Pin versions, run the tool on a small job first, and review the first outputs before widening access.
Watch for
- The hosted API needs an account and a key, and usage is metered by the vendor. Check current pricing before building a high-volume job on it.
- The open-source license is AGPL-3.0. Review what that means for your deployment before self-hosting or embedding it.
- No independently checked benchmark is published by AgentsUse for this tool yet. Coverage and latency figures on the vendor site are vendor claims.
