Mantle's SASI gave Shopify developers a single place to see where their apps stood. With it winding down — and merchants increasingly asking AI instead of browsing the App Store — the question moved. This is where your app stands across ChatGPT, Claude, Perplexity and Gemini.
SASI (the Shopify App Store Index, by Mantle) was a reference a lot of app developers leaned on to understand where their apps ranked and how the store moved over time. Mantle has announced it's winding down, and the data won't stick around — so the developers who relied on it need somewhere else to look.
App Store rank still matters, but it's no longer the only place discovery happens. Merchants increasingly ask ChatGPT, Claude, Perplexity and Gemini which app to install, and Shopify's Sidekick recommends apps right inside the admin. If those models don't name you, you're invisible to whoever asked — no matter your App Store position. The new “where do I stand” is across four AI assistants, not one index.
Every day NextSASI asks the four assistants to recommend the best Shopify apps across 16 categories and records where each app lands. The four barely agree — in some categories their top picks overlap less than 20% of the time, and an app that's #1 in one model is often missing from another. You can look up any app and see exactly where it's recommended and where it's invisible, free. See the methodology for how it's measured.
Yes. Mantle announced that SASI — its Shopify App Store Index, which a lot of app developers used to see where their apps stood — is being wound down, and the historical data won't persist. That's left a gap for developers who relied on it.
It depends what you used SASI for. If it was App Store rank tracking, a few analytics tools still cover that. But the bigger shift is where merchants now discover apps: increasingly they ask ChatGPT, Claude, Perplexity or Gemini, and Shopify's Sidekick recommends apps in-admin. So the modern version of "where do I stand" is AI visibility — whether and where the assistants recommend you. That's what NextSASI tracks.
No. NextSASI is an independent project and is not affiliated with or endorsed by Mantle or SASI. It's a different take on the same question SASI answered — "where does my app actually stand" — built for the AI era, measuring the four AI assistants instead of the App Store index.
Every day it asks ChatGPT, Claude, Perplexity and Gemini to recommend the best Shopify apps across 16 categories, and records where each app ranks in each model. The headline finding: the four assistants barely agree — an app that's #1 in one is often invisible in another.
Yes — the public report and looking up any app across all four assistants are free, no signup. You can also leave an email for a short monthly summary of new apps and movers.
