Waitlist specialist or waitlist-plus-pre-order?
Checked 23 August 2026
Back in stock alert & restock alert for out-of-stock waitlists
Grow sales with preorders, 'notify me' & back in stock alerts
Both apps sit at 5.0 with more than 3,500 reviews, so quality is not the differentiator. Scope is. Kbite does restock waitlists and stops there, and doing one thing means fewer settings and fewer ways to misconfigure it. STOQ also handles pre-orders, which matters if you sell drops, run presales, or expect to. Installing the narrower app and migrating later is a real cost — sign-ups do not always move cleanly between vendors — so the question is genuinely about your next twelve months, not today.
Back In Stock, Notify Me: Kbite takes 1 round, Preorder, Back In Stock — STOQ takes 2, with 2 tied.
| Axis | Back In Stock, Notify Me: Kbite | Preorder, Back In Stock — STOQ | Why |
|---|---|---|---|
| Waitlist execution | Tie | Tie | Both handle variant-level sign-ups and fire alerts promptly on restock. There is no meaningful gap in the core job. |
| Pre-orders | — | Wins | STOQ covers pre-orders; Kbite does not. If a presale is anywhere on your roadmap, this decides it. |
| Simplicity | Wins | — | A focused app means a shorter setup and fewer settings to get wrong. For a store that will never run a presale, STOQ's extra surface is overhead. |
| Free tier | Tie | Tie | Both offer free plans that cover low sign-up volume, with paid tiers as your waitlist grows. |
| Mixed carts | — | Wins | Only relevant if you run pre-orders — and if you do, test carts mixing pre-order and in-stock items explicitly. It is the most common complaint in this category. |
