Questions
How many products can I compare?
Two to five, all from the same topic, because each topic has its own six criteria and weights.
Why can I not compare products from different topics?
The criteria differ by topic. An MCP gateway and a workforce identity provider are scored on different questions, so a combined table would compare unlike things.
Where do the scores come from?
From the topic pages. Every score has a one-line reason and a link to the public page it is based on. The method page explains how the totals are calculated.
