Apps for Shopify merchants

Small apps that do one job, properly.

ExtStore builds focused tools for running a Shopify store: rules that hold at checkout, backups you can actually read. Installed from the Shopify App Store and billed through Shopify.

The apps

Each app installs from the Shopify App Store and opens from the Apps section of your Shopify admin.

Checkout Rules

Free plan · Pro $9.99/mo

Stop orders you can’t fulfil, before checkout completes.

  • Order minimums, maximums and quantity limits
  • Allow or block countries and ZIP or postal codes
  • Members-only access by customer tag or login

Git Sync

Free plan · paid from $9/mo

Every store change, kept in a GitHub repository you own.

  • Saves edits as they happen, with a daily catch-up pass
  • One readable JSON file per product, page or collection
  • Compare with the live store and restore, images included
  • Never force-pushes; the backup outlives the app

More to come

The next app is on the bench. If a gap in your store’s admin keeps costing you time, tell us about it: that’s how these apps start.

How we build them

01

On Shopify’s own surfaces

Built on Shopify Functions and the Admin API rather than theme scripts, so nothing slows your storefront or breaks on a theme change.

02

Billed through Shopify

Plans appear on your Shopify invoice. No separate account, card or contract to manage.

03

Your data stays yours

Each app reads only what it needs, never sells or shares it, and deletes what it holds about your store within 48 hours of uninstall.
