Restock Rocket alternative
A Restock Rocket alternative that re-checks stock before it emails
Most restock apps email your waitlist the instant inventory ticks above zero — even when the product still isn’t buyable. Back in Stock re-verifies live stock at the moment it sends, so a shopper never lands on a sold-out page.

Heads up: Restock Rocket was renamed STOQ (by Artos Software) in 2026. This page compares Back in Stock with that app as it’s listed today.

The real difference: it re-checks stock before it sends
Most restock apps fire on the inventory webhook. We re-check before we send.
An inventory webhook reports a quantity, not whether the product can be bought. That gap sends emails for things nobody can buy — wrong location, unpublished product, sold out again, wrong variant. Back in Stock re-verifies live stock at the moment it sends, and holds the alert if the item isn’t actually purchasable.
The verdict
Need pre-orders and deposits? STOQ does that; we don’t. Otherwise the question is simple: if what bites you is alerts firing for products that aren’t actually buyable — the wrong-location, sold-out-again, wrong-variant emails that make your list stop opening — Back in Stock is the one built to prevent it, at a flat $19/month that doesn’t climb as your list grows.
Pricing
Free to start. Flat $19/month when you grow.
Back in Stock is a flat $19/month with unlimited alerts, plus a free plan to start. No per-email or per-SMS tiers to climb as your list grows — the price is the price.
