These 3 apps lead WordPress Plugin Directory's Async category as of September 2026 — ranked by user rating, review count, and audit score, refreshed every 24 hours from the canonical WordPress marketplace listing.
Discover the top-rated async apps available on WordPress Plugin Directory. Rankings based on user ratings, review count, and market performance.
This is the curated shortlist — the top-ranked async apps. To browse every async app on WordPress Plugin Directory, see the full Async category.
This list ranks the top 3 WordPress apps classified under Async by the source marketplace's own taxonomy — apps appear here only because WordPress Plugin Directory itself tags them in this category, not because of any AppRanks editorial decision. Within the category set, ranking uses a Bayesian-ish blend of average rating × natural log of review count: the formula is rating × ln(reviewCount + 1), so a high-rating-low-review app doesn't leapfrog an established listing on a single 5-star outlier. The blend favors apps that are both well-reviewed AND have an established user base.
AppRanks does not invent a proprietary score for public surfaces — the rank shown mirrors the marketplace's published category position exactly, scraped on a 12-24 hour refresh cycle from the canonical WordPress Plugin Directory listing. The category lookup happens at request time and the page is cached at the edge for 1 hour to absorb traffic spikes; the underlying ranking data refreshes daily so the list stays accurate within one day of any source change. AppRanks does not editorially promote or demote apps based on advertiser or partnership status — the same blend formula applies uniformly across every app on this platform.
