The Stack

What the best brands run.

Apps organized by the job they do for a founder, from getting found to running the shop. Adoption comes from our scan of 936 storefronts. Each Best-in-Class pick is the app the 20 top-graded brands run most, named only when at least 3 of them run it.

Meet the Stack

What each app does in its own words, who it is best for and which brands we spotted running it.

Adoption = share of the 936 storefronts we scanned on Oct 9, 2026 where public storefront code shows at least one app in that lane. Apps that run only in checkout or the back office may not show up, so missing is not proof of absence. Ad pixels and Google Analytics are not counted because they usually load through a tag manager our scan cannot see into. Top 20 graded = the 20 highest Storefront Evidence Scores. Best-in-Class picks come from that data and never from partner status. Partner means a live referral link; it never changes a grade, a ranking or a pick. A few links to software partners are referral links, and we may earn a commission if you sign up, at no cost to you. Money never changes a score.
