The best rated Shopify theme
stars-5
It really is the best Shopify theme.
This theme includes so many features that you will hardly need external paid apps, which will lighten your site, increase its speed, avoid and above all save you money.

In addition, the customer service is just top notch, they respond quickly and very, very effectively to any question and it's just great to be supported like that when you launch your store.

I even have the feeling that the theme is not expensive enough considering everything it offers.

A 10/10 in terms of quality of exchange and service for the support team; it is more than a pleasure to call on them (almost like wanting to create problems on purpose to discuss 🤣).

And, honestly, I have rarely seen a theme as crazy as the one they offer us; V2.0 🤩.

Thanks for everything.

“I would have liked to know this theme sooner in person... it's a huge time-saver.

The theme is optimized as possible, it looks very professional and it is so intuitive!

But I would still like to highlight customer support. Never seen such quick feedback (my question sent by email at 6 pm, an answer the same evening).

So thanks to Nezha who was efficient and super fast, she solved my problems in no time and especially her little word of encouragement warmed my heart and boosted me [...]”

I am really impressed by this theme! It is super intuitive, easy to handle and above all very aesthetic. We feel that everything has been designed to facilitate the creation of the site: the functionalities are numerous, useful, and very well integrated.

A huge strength: customer service. A big thank you to Nehza, who answered all my questions with incredible responsiveness. Always available, very professional and really effective. We feel that they are taking the time to help!

I recommend 100% 🔥🚀

“It's clearly the best Shopify theme I've ever seen. Even though the previous version was great, 2.0 is a glitch! Thanks for the flexboxes 💜

The theme is super well built, very easy to use, with many clear tutorials, full of features that normally require the installation of applications. There is even a “Design System” section to make it easier for us to configure colors, fonts, etc.

Even their team is super responsive, if necessary they are really attentive. In short, there is so much to say, just remember that it is a complete theme that will allow you to save time and especially money! Thanks again 🏾”

“My experience with Fullstack has been super positive!

This is not the first time I have used Shopify, but the other themes are quite limited in terms of possibilities and customer experience.

The Fullstack theme met all my expectations, especially on all the features I wanted for my site!

And the customer service is just top notch, as soon as you have a question, you have an answer in less than 12 hours, the service is super responsive and very professional!”

I am thrilled with the Fullstack theme!
The design is modern, fluid and is exactly what I was looking for, best investment.

But what really makes the difference is their support: highly responsive, patient, professional and very kind. I was guided and supported on several points, and everything was resolved quickly.

I 100% recommend it to anyone looking for a reliable theme, and especially well-followed!

“A serious company, a team available for any questions and responsive. We know why we are taking this service, we are not lost in nature, the quality is there!

I tried to get started with the free Dawn theme and I had so much trouble with all the applications to install... switching to full stack, it's day and night: I save time on everything because everything is clear and optimized.

Time is money, I would have liked to have known them before...”

Q&A

Frequently asked questions

The most frequently asked questions about the theme

Can I try the theme for free?

Yes, all of our plans offer a 14-day free trial. If you cancel during this time, you won't pay a cent. On the other hand, be careful, the theme could well please you for good...

Can I use my license on multiple Shopify stores?

1 subscription = 1 license = 1 store.

If you are a service provider and you want to use the theme with several of your customers, you can subscribe to the Enterprise package.

Are there regular updates?

Absolutely! Our developer team is always working on new applications, improving features, and fixing bugs, so you have the best possible experience.

You can request the features you want on the roadmap.

Do you provide resources to help us set up the theme?

The FullStack Theme is accompanied by a member training area to help you:

- Understand each element behind the theme's ecosystem
- Activate your license and upload the theme to your Shopify store
- Configure each theme element, sections, and features
- Adopt a methodical process to explode your results in E-commerce
- All the best practices to get the most out of your users
- Responsive customer support
- Pre-designed page templates to integrate in 1 click

What is the difference between the FullStack Theme and other themes?

There are 2 types of themes on the market:

- Professional looking themes but with zero functionality to convert
- Themes that include dozens of features but are 10 years behind schedule in terms of design

The FullStack theme encompasses the best of both worlds: Conversion AND professional rendering. It is the uncompromising theme.

The FullStack theme is not specially designed for beginners, nor for big brands. It integrates all the features and sections you need for your first sale and during all stages of your growth.

Starting with the FullStack theme guarantees you a healthy architecture for the coming years.

Why isn't the FullStack Theme in the Shopify app store?

Well yes, if your theme is so good why don't you sell it on the Theme Store?

The answer is simple: Shopify imposes functionality limits, design standards, and a limited business model, which restricts us in what we want to offer with FullStack.

To get rid of all its limits, and keep our independence with the subscription model, you made the choice not to publish FullStack on the Shopify Theme Store.

If Shopify decides to offer more freedom on its platform in the future we will be happy to publish it.

How do I cancel my subscription?

You can cancel your subscription in a single click from your member area. Your accesses and licenses will be removed 1 hour later.

What is the best Shopify theme?

The best Shopify theme is definitely the FullStack Theme. It's the best theme on the market right now, whether you're selling a single product or multiple products. It's easy to customize, fast, and optimized for conversion by CRO experts.

What are the best free themes for Shopify?

The best Shopify theme is definitely the FullStack Theme, you can try it free for 14 days. If you want a 100% free theme, you can turn to the Horizon theme suite offered by Shopify. These are neutral themes, but pretty and well-coded. A good starting point.

How to choose the right Shopify theme?

Choosing the right theme is crucial for the success of your store.

To make the best choice, focus on three pillars:
- Charging speed: A lightweight theme improves your SEO and reduces the bounce rate.
- The mobile experience: More than 80% of sales are made on smartphones; your site must be flawless on the small screen.
- Native features: The fewer third-party applications you install, the faster and more stable your site stays.

Why do we recommend the FullStack theme?
If you are looking for a perfect compromise between design and performance, the FullStack theme was specifically designed by SEO and CRO (conversion optimization) experts.

Unlike traditional themes, it natively integrates dozens of features (Upsells, Mega Menu, Cart Drawer, etc.), allowing you to save hundreds of euros in application subscriptions while guaranteeing an optimal speed score. It is the ideal tool for those who want a professional store that is ultra-fast and ready to convert upon installation.
