Overview

Stack Overflow Scraper gives agents a reliable path into developer Q&A signals without maintaining a custom crawler. Search by keyword, tag, or both, then optionally pull answer rows for the returned questions. The tool normalizes public Stack Exchange API records into compact question and answer payloads for technical research, developer support triage, content planning, and product opportunity discovery.

Search for recurring questions around an API, framework, error message, or product category and hand an agent structured titles, tags, scores, views, and body text.

Documentation gap analysis

Fetch public questions and top answers for a technology so docs teams can see where developers struggle and which explanations already work.

Support and DevRel monitoring

Monitor new or relevant Stack Overflow questions by keyword or tag and route high-signal issues into support, community, or DevRel workflows.

FAQ

Does Stack Overflow Scraper need a Stack Apps API key?

No. Version 0.1 uses public Stack Exchange API endpoints through Better Fetch and does not require a Stack Apps key or authenticated Stack Overflow account.

Can it fetch every answer and comment?

Not yet. Version 0.1 searches questions and can fetch a bounded batch of top-voted answers. Comments, all-answer pagination, profile enrichment, and cross-site fan-out should be added as separate validated slices.

Can I search sites other than Stack Overflow?

The input includes a site parameter for Stack Exchange site slugs, but the page and benchmark are optimized for Stack Overflow. Broader Stack Exchange coverage should be verified per site before being promoted.
