Low-stock alert apps for Shopify, compared honestly

Low Stock Alerts & Notify Me vs typical low-stock alert apps — what you actually get, no spin.

You're searching this because you've run out of a bestseller before and want a heads-up next time before it happens again. Most low-stock/back-in-stock apps for Shopify (the platform many online stores run on) do the same basic job — watch inventory, alert you at a threshold — but differ in plan tiers, alert channels, and how much dashboard you have to configure to get there. Here's an honest look at what Low Stock Alerts does and how it stacks up against the category norm.

FactorLow Stock Alerts & Notify MeTypical low-stock alert app
PlansSee the listing — Free plan (restock signups capped at 25 a month) + Pro planOften tiered by SKU count or alert volume — see each app's listing for current tiers
Free trialNo free trial — the Free plan itself has no time limitVaries — commonly 7 to 14 days
SetupSet a threshold, add an email (or webhook), save — no theme editsUsually similar, though some require Liquid snippets for on-page badges

Per-variant thresholdYes — any variant dropping to your threshold fires an alert, on the Free planCommon, but sometimes store-wide only on lower tiers

Where we lose, and why merchants still pick us

Low Stock Alerts covers both sides of stock alerts on one free plan: it pings you the moment inventory drops to a threshold you set (email), and it shows shoppers a "notify me when it's back" signup on sold-out variants, then emails them automatically once you restock. Every product and variant is included on the Free plan, with restock signups capped at 25 a month — no per-SKU tiers, no dashboard to learn. A paid Pro plan adds per-product thresholds, Slack alerts, and CSV export.

What Low Stock Alerts deliberately leaves out is SMS and broader marketing automation — if you need multi-channel campaigns layered on top of restock alerts, a heavier marketing suite may fit better. We're also new, so if an established track record matters more than a simple, flat feature set, that's a fair reason to look elsewhere first.

Common questions

Is Low Stock Alerts & Notify Me free?

Yes — the Free plan covers both the merchant-facing low-stock alert and the customer-facing back-in-stock signup, on every product and variant, with restock signups capped at 25 a month. There is no free trial because the Free plan itself has no time limit; a paid Pro plan is available for per-product thresholds, Slack alerts, and CSV export.

Does it notify my customers, or just me?

Both. The app alerts you (the merchant) when inventory drops to your threshold, and it also shows shoppers a 'notify me when back in stock' signup on sold-out variants, then emails them automatically once you restock.

Do I need to edit my theme?

No — Low Stock Alerts installs and runs without touching Liquid or theme code. Set a threshold and an email or webhook, and you're done.

Will I get spammed with repeat alerts?

No — one alert per dip below your threshold. It auto re-arms only after the item restocks above that number.

Does it work per-variant?

Yes — every variant is watched independently, so a specific size or color can trigger its own alert.

One threshold, one alert, every product and variant included on the Free plan.
