Mechanic

We’ve replaced several apps with just this one!
I've used Mechanic for about a year now. Their huge library of pre-built tasks made it easy to get started auto-tagging customers or orders, scheduling product publishing, sending notifications for big orders. Setup was easy.
When I needed something custom (a complex order hold and release workflow), I was easily able to learn enough Liquid to modify an existing task to achieve what I wanted. The documentation is good, and their Slack community is also super helpful.
If you've ever thought "I wish Shopify could just do X automatically," this is probably your answer.

Mechanic is our most important app for running our store - it handles all of our workflows on the backend, and helps us automate everything from sales, special events, sending orders to vendors, keeping track of preorder, backorders, inventory, and more. It's incredibly powerful and easy to learn for a developer. The documentation is also great, and there is a community on Slack that is ready to help if you run into anything complicated. The developer is also super responsive when you have questions. Overall, we couldn't be happier with Mechanic! This is the best app on Shopify hands down.

Mechanic has been an essential tool for our shop.

We’ve used it to build and manage systems that go beyond Shopify’s native functionality, including pre-ordering, a rewards points program, a referral system, and a raffle system tied to real customer activity.

What stands out most is how flexible and reliable it is. Once a task is set up, it just works, and it gives us confidence that important automations are running exactly as intended. The support team has also been responsive and helpful whenever we’ve had questions or needed approval for specific functionality.

Mechanic has played a huge role in helping us shape our shop into what we envisioned. Highly recommended.

Mechanic was the answer to a process issue that has taken us months to solve. We were looking to send customer emails when we add a tag to their order or customer record. The key was the email needed to include order specific fields and customer metafields. We had tried multiple apps over several months and nothing could accomplish this. Then we came across Mechanic. Once it was downloaded and setup for email we were able implement our solution in less then an hour. So easy.
This app is wonderful. It has a tremendous library of tasks that can be implemented. We are also using it to schedule sale price changes and reverting back to original price.
Highly recommend this app.

Mechanic is awesome! Extends your store in so many ways, and replaces so many apps. Totally worth it, and support is amazing and fast

I love this app. I got it specifically to sync my blank t-shirt stock across my inventory so that I could offer a bigger range of products without fear of overselling. It has worked brilliantly for that. But also I have found many other uses, my favourite being getting it to check my entire inventory for a specific SKU and based on that add a new SKU in a new size, meaning I could add a new size of shirt to a couple of hundred items with just a few clicks. As well as monthly randomisation of the product order in some of my collections. Not the cheapest app, but the scope when you start to think about what it can do is really quite incredible.

Matt and his team are exceptional. My developers are in love with this app, and have installed it on all of our stores. If you constantly find yourself thinking 'I wish Shopify would do this..' or find any limitation in Shopify, this app solves it.

No gimmicks, no 'it's in our roadmap' it just WORKS.

10/10

This is hands down the most incredible app in the app store. Over the years I've used it to automate fulfillment of customized products, support our customer service team with problematic order flagging, build sophisticated data workflows (now that metafields/objects exist), and generally solve so many problems when someone says to me "we need a new app that does X" or "can you source a software that does Y". If you're creative, if you're a systems-minded person...you can almost always leverage Mechanic to solve your complex automation problem on shopify

Mechanic's automated jobs has saved us a ton of $$$ and time. We love the customer service and the product's job uptime is 99%... which is awesome.

(March 2025 Edit: 4+ years on and Mechanic is serving us as well as ever. You couldn't ask for a better partner for your Shopify store!)

It's rare that I feel passionate about a Shopify App, let alone any app at all. Mechanic however—I'm in love . Shopify has incredible API support, but it can be challenging to make use of the APIs to their fullest, even for a seasoned developer. Even if you have the skills, you still need to build your own application to make use of the APIs, worry about choosing a build environment, hosting, deployment, maintenance, downtime, and all the other stuff that comes with a custom solution. Alternatively, you can use an automator/integrator like Zapier, but then you're limited to the functionality that the automator platform chooses to expose.

Mechanic removes all that, and give you access to the full power of Shopify's API's, all using the familiar language of liquid that so many of us developers work with day in and day out. It used to be that if I needed a small custom solution for one of our shops, I would spend days trying to remember how to set up a Ruby environment, get it hosted on Heroku, get webhooks working, and then have a barely working application that did just that one thing and nothing else.

Since using Mechanic for the past half-year, I honestly don't think I'll ever build a custom Shopify application again. Mechanic has empowered to me to create all kinds of solutions for our business that I never even considered attempting in the past—the barrier to entry was just too high. With Mechanic, I can just write a task to do whatever I want, and best of all, *have fun doing it.*
