Limits and method

23

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages do not mention any competitors by name. Evidence gaps include lack of detailed security compliance certifications, uptime statistics, and independent review ratings beyond the Chrome Web Store. The product does not execute JavaScript during crawls, which may limit detection of client-side issues S49. Pricing details for annual plans are not fully specified on the pricing page, though the research table provides them.

24

Sources, method, and limitations

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

This report is based on 15 collected pages from checkbot.io, including the homepage, FAQ, reviews, press kit, and release notes. The evidence catalog includes 180 entries, with external proof search limited to one web search. Pricing information was supplemented by an owner-reviewed research table. Limitations: external review snippets were not scraped, and some claims rely on self-reported data.
