About Guardrail
Monitor inventory in real time and catch anomalies. Auto-pause products before they oversell.
Overselling usually isn't caused by running out of stock. It happens when a number goes wrong quietly, so you hear about it from a customer instead of your store. Guardrail watches your inventory as it changes and flags anomalies like negative stock, low buffers, and sudden jumps. It emails you when something looks wrong. You can set a safety buffer so a product is paused from sale before it oversells. It never changes your stock counts, and it deletes your data when you uninstall.
Listing highlights
- Real-time inventory monitoring across all your locations
- Alerts for negative stock, low buffers, jumps, and rapid swings
- Auto-pause a product before it oversells, reversible anytime
- Email alerts so you catch problems even when you're away
- Safe by design: never changes stock, deletes data on uninstall

How Shoplist knows
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows Guardrail on a store, it is there.
- Counts are based on Shoplist's latest available public crawl signal dated July 22, 2026.
- Shoplist has not yet found reliable public storefront evidence connecting a Shopify store to this app. This does not mean the app has no users. Some apps are new, admin-only, server-side, theme-independent, or otherwise difficult to detect from public storefront signals.
- Merchant rows are filtered to public brand profiles with enough public data to link safely. Full workflow, filtering, and monitoring stay behind signup.
- Review, pricing, feature, screenshot, and listing-change data come from public Shopify App Store and Shoplist crawl records. Signals can change between crawls.
