Limits and method

22

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages do not mention specific competitors by name, except for a passing reference to Octoparse as a UI-based scraping tool S9. Evidence gaps include lack of detailed pricing for Enterprise plans, no independent customer reviews, and no information on company ownership or uptime status. Open questions remain about the exact capabilities of the Knowledge Graph and the full scope of the self-hosted web search offering.

23

Sources, method, and limitations

Evidence inventory, collection method, provider use, and constraints.

This report is based on 15 collected pages from diffbot.com, including product pages, documentation, pricing, and changelog entries. The evidence catalog includes static and rendered page captures. External proof search was enabled but no verification requests were made. Limitations include the absence of third-party reviews and limited information on enterprise offerings.
