Mechanic is a development platform for Shopify. :)
Super simple. Scans all inventory levels in your store, on demand, and brings the negative ones back up to zero. Optionally, configure this task to run nightly.
Runs when a user triggers the task and when a bulk operation finishes. Configuration includes run daily at midnight.
Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Gurus, everybody.
That’s why we make it easy to configure automation without code, why we make it easy to tweak the underlying code once tasks are installed, and why we publish it all here for everyone to learn from.
