Next
Something else breaking?
We build the next app from what merchants tell us. If Shopify does not do something you need at checkout or in admin, say so.
How every Mastiff app is built
Four rules, same for each app.
One job
No bundles, no upsells to features you did not ask for. If you need two things, that is two small apps.
Enforced where it counts
Rules run in Shopify checkout or admin, not in a theme script a wallet button can skip.
Test before you turn it on
Simulators and previews show exactly what the shopper or the printer will get.
Free stays free
Free plans are real plans. Paid plans start under $10 a month with a 7-day trial.
Founders rate: first 100 stores on any Mastiff app
A permanent discount on the top plan, applied as an automatic monthly credit. We would like to hear from you: email [email protected] with your .myshopify.com domain. The credit is applied to paid plans either way.
