Seam vs Mida

At a glance

All figures observed on the Shopify App Store and the vendor documentation on 15 August 2026. Pricing on this listing has moved before, so check the date.

The difference that actually decides it

Mida watches your storefront. Seam reads your store records. That is not a positioning distinction, it is a difference in what physically gets collected.

Because Mida runs on the storefront, it can show you the thing no API can: an actual recording of a person moving through your site, where they hesitated, where they clicked something that was not a link. It also builds click, move and scroll maps, and ties clicks to revenue.

Because Seam runs on the Admin API, it can see orders, revenue, refunds, customer journey attribution and product mix, and it never sees a single visitor as an individual.

If you are trying to work out why a page is failing, that is Mida. If you are trying to work out what happened to your store yesterday, a recording of one visitor is not the answer.

The theme app embed is the real structural difference

Mida documentation is explicit about setup: install from the Shopify App Store and turn on the app embed. That means going into Online Store, Themes, Customize, App embeds, and toggling it on.

This is not a criticism, it is how any session recording tool has to work. You cannot record a session from an API. But it has consequences worth knowing before you install: the embed lives in your theme, it has to be re-enabled if you switch or duplicate themes, and a script running on every storefront page view is a different risk profile from a server-side integration.

The vendor states that Mida loads asynchronously and does not noticeably affect store performance, and the app carries Shopify Built for Shopify badge, which Shopify awards against its own performance, design and integration standards. No independent page-speed benchmark was found either way, and no critical review we read complained about site speed.

Seam requires no embed, no script and no theme change, because it never touches your storefront. That is not a virtue, it is the reason it cannot do what Mida does.

Where Mida is genuinely stronger

Session replay and heatmaps, which Seam does not do at all rather than doing worse.

The free tier is a real product rather than a crippled trial: 300 sessions a month, unlimited heatmaps, and AI summaries per the Shopify listing. For a small store that is often enough to answer a specific question without paying anything.

The revenue linkage is a genuine differentiator, and reviewers say so specifically rather than repeating marketing copy. A 24 April 2026 five-star review praises being able to review "stage of sales from view to cart to completed sale" against the actual session.

Breadth for the price. Recordings, three kinds of heatmap, funnel and checkout drop-off visualisation, and on-site surveys in one app at $9.90 is a lot of surface area.

The data retention question, which Mida own pages answer twice

This is the one thing we would want to resolve before installing, and we could not, because two vendor-controlled pages disagree.

The Shopify App Store listing states "lifetime analytics data storage" on every plan, including the free one. The vendor own pricing page at mida-app.io states storage limits of one month on the lower tiers and two months on Advanced, with custom terms for Enterprise.

Those cannot both be current. We are not going to guess which is, and the difference is not academic: whether your recordings survive a month or indefinitely changes what the product is for. The published tier prices and session caps also differ between the two pages, which suggests one surface is simply stale.

The Shopify listing is the surface that actually bills you, so that is the one we have used for the pricing table above. Confirm both before committing, and treat any retention claim from either page as unconfirmed until the vendor makes them agree.

What merchants raise in critical reviews

The sample is too small to call anything a pattern, and we are going to say that rather than dress up four complaints as a trend.

Of roughly 488 reviews on 15 August 2026, about five or six are one star and two or three are two star, together around 1 to 2% of the total. About 96% are five star.

Two dated individual complaints, reported as such. A one-star review from 27 January 2026 says: "Within MINUTES of installation, MIDA recorded 350+ 'sessions' from the USA, Ireland, and other countries - all clearly bot traffic." A two-star review from 23 June 2026 says: "it tells me there are errors, and when i do replays, i can't see where the error is happening." The developer replied publicly to the first.

The bot-traffic point is worth noting not as a verdict on Mida but because session-volume pricing and unfiltered bot traffic interact badly by construction: if bots consume your session quota, you pay for traffic that never had a chance of buying.

What we could not verify

Whether the theme app embed is removed automatically on uninstall, or left as an orphaned block requiring manual cleanup. No vendor documentation addresses it.

Whether uninstalling actually deletes stored recordings. The privacy policy says data is stored until you submit a cancellation request or uninstall the app, which implies deletion but states no timeline or procedure.

The app exact current display name. The listing heading, the page title and third-party mirrors give three different long-form names, which usually means a rename that has not propagated. We have used "Mida" throughout for that reason.

Choose Mida if, choose Seam if

Choose Mida if you have a specific storefront problem and want to watch it happen: a checkout step losing people, a page nobody scrolls, a button nobody finds. The free tier means you can answer one question for nothing.

Choose Seam if you want to know what changed across the whole store without opening anything, and you care about orders and revenue rather than clicks and scroll depth.

Both is reasonable, with one caveat specific to this pairing: Mida costs a script on every storefront page view and an embed in your theme, so it is worth being deliberate about rather than installing and forgetting. If you install it to investigate something and the investigation ends, consider whether it should stay.

Common questions

How much does Mida cost?

Per the Shopify listing on 15 August 2026: a free Starter tier at 300 sessions a month, then $9.90 for 5,000, $24.90 for 15,000 and $44.90 for 40,000 sessions monthly. The vendor own pricing page shows different figures, so confirm before committing.

Does Mida require a theme app embed?

Yes. The vendor documentation says to install from the App Store and turn on the app embed, which is done in the theme editor. It has to be re-enabled if you switch themes, unlike an API-only app.

How long does Mida keep session recordings?

Unclear. The Shopify listing states lifetime analytics data storage on all plans, while the vendor own pricing page states one to two months depending on tier. Those two vendor pages contradict each other and we could not resolve which is current.

Can I use Seam and Mida together?

Yes. They collect different data by different means: Mida records storefront sessions through a theme embed, Seam reads store records through the Admin API. The only thing to weigh is whether you want a recording script running permanently.
