HeyMantle shutting down: what it means for Shopify apps and SASI users

HeyMantle (heymantle.com) has told customers it is winding down in an email message. The message was straightforward: the company is shutting things down, and there is no new owner taking over. For a tool that sat at the center of how a lot of Shopify apps handled billing and analytics, that is a meaningful event, and it raises two practical questions for app developers. Why is this happening, and what should the people who relied on it do now.

The likely reason

No public statement has explained the decision in detail, so anything here is informed speculation rather than confirmed fact. But the timing points at one obvious place.

On May 12, 2026, Shopify rolled out Shopify App Pricing, which replaced Managed Pricing as the default billing system for apps. The change was bigger than the name suggested. Usage based billing became native. The App Events API turned per action charging, the kind of metered billing that used to require real engineering work, into a configuration step in the Partner Dashboard. Shopify also shipped two new APIs, an Active Subscription API and a Historical API, that give developers persistent subscription status and a full event log directly from the platform.

That matters because billing and revenue analytics were the core of what Mantle sold. Charging a flat monthly fee was never the hard part, since Shopify has supported that for years. The hard parts were metered usage billing and turning messy billing data into clean revenue reporting. Both of those became native platform features in a single release. When a platform absorbs the layer a company is built on, the company's product can be perfectly good and still lose its reason to exist. That is a more coherent explanation for a sudden, clean wind down than the usual story of a startup running out of runway.

What it means for Shopify apps

If your app used Mantle for billing, you will need to move to Shopify App Pricing. The destination already exists and is now the default, which makes that part easier. Existing charges keep running for now, and Shopify has said migration tooling is coming, though at the time of writing the cutover for live apps still depends on tooling that has not fully shipped. If you depended on Mantle's reporting and dashboards, you lose those, and you will be rebuilding that visibility on top of Shopify's new subscription and historical APIs or another tool.

The billing side has a clear path. The analytics side is more of an open question, and it gets sharper when you look at one specific piece of what Mantle owned.

SASI is going down with it

In May 2024, Mantle acquired App Store Analytics and the Shopify App Store Index, better known as SASI. SASI was the part of the picture focused on app store optimization: keyword tracking, ranking data, and visibility into how apps performed in App Store search. After the acquisition it became a secondary feature inside a billing platform rather than a standalone product.

If Mantle winds down, SASI goes with it. For developers who used it, that means losing their keyword and ranking tracking. It also means losing their history, and that is the part that is easy to overlook in the moment. Ranking and keyword data is a time series. You cannot recreate last year's positions after the fact. Once the tracking stops and the data goes away, that history is gone for good, and any replacement starts your record over from the day you sign up.

What to look for in a replacement

If you relied on SASI, the practical move is to start tracking somewhere else soon, so the gap in your history is as short as possible. A few things are worth checking in any tool you consider.

Does it track keywords and rankings daily, so you actually have a usable time series rather than occasional snapshots. Does it explain why rankings move, not only that they moved, since a change with no cause attached is hard to act on. And is app store optimization the actual focus of the product, or a side feature, because the SASI situation is a fair reminder of what happens to features that are not central to the business they live in.

The options

There are a handful of tools in this space. AppStorePulse and Rankbase both track Shopify app store data and are worth a look depending on what you need.

AppJubilee (appjubilee.io) is built specifically for this problem. It tracks keywords and rankings daily, focuses on explaining the cause behind ranking changes rather than only reporting them, and gives prioritized recommendations you can act on. Because it is a dedicated app store optimization platform rather than a feature inside a larger billing tool, it is not exposed to the same fate SASI ran into. It will not promise you installs. What it does is give you the intelligence to understand your position and decide what to do about it.

Closing

It would be a mistake to let the analysis crowd out the obvious: HeyMantle was good, and it mattered. For three years it gave Shopify app developers a clearer view of their own businesses than most of them had ever had. It took billing, revenue, and customer data that used to live in scattered exports and spreadsheets and turned it into something people could actually run a company on. Plenty of app businesses made better decisions because of it, and more than a few grew on the back of the visibility it gave them. The team built with real care for the app partner community, and that came through in the product. A tool earning that kind of loyalty from the people who used it is rare, and Mantle earned it. It will be missed, and the developers who relied on it have good reason to be grateful for what it gave them while it was here.

Endings in this ecosystem are part of the deal, but they don't erase what was built. The practical task now is continuity.
