How the shortlist works
We first compare the number of required capabilities documented in official sources. Each contributes three points; optional capabilities contribute one. For the lowest-cost budget, a public free option adds one point and a confirmed monthly USD entry price of $50 or less adds one. Free eligibility and access to required features must still be checked. Unverified capabilities receive no points and are not labeled unsupported. Self-hosted and conditional open-source programs do not get the public-free bonus.
Ties use score, then alphabetical order. A higher price or a larger hypothetical budget band does not imply better quality. The shortlist is a starting point, not a recommendation to purchase a particular plan.
