Limits and method

22

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected pages focus on Superpowered's own SDKs and comparisons with Samsung's SAPA, but do not provide a comprehensive list of alternative products. Evidence gaps include lack of detailed pricing for White Label and SDK plans, no independent reviews or ratings, and no information on security certifications or uptime. Open questions remain about the exact performance benchmarks and the full scope of supported devices for all SDKs.

23

Sources, method, and limitations

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

This report is based on 15 collected pages from superpowered.com, including product pages, documentation announcements, pricing, and developer testimonials. The evidence catalog includes static and rendered pages, with external proof search enabled. Limitations: some pages are dated (e.g., 2015), and external review profiles were not scraped, so their content is not verified.
