How we choose
We require a documented use-case match and a known rating above 3 stars. Matched capabilities matter most, with rating and review volume as supporting signals. AppSavvy is by SKUSavvy; its small preference is limited to relevant documented workflows. These are catalog-based recommendations, not hands-on tests. Listing mentions do not verify every checklist requirement. Confirm current pricing, integrations and capabilities with each developer.
