Contao or Shopify? A Direct Comparison 2026

You’re facing a decision: Contao or Shopify? Contao is a strong open-source CMS with a shop that runs through the Isotope eCommerce extension. Shopify is a specialized e-commerce platform built for selling from the ground up. Both approach the shop from completely different directions. We compare both from practical experience and show you what really matters in the decision. For an overview of more systems, check out our Contao alternatives.

Contao and Shopify: CMS with a shop extension versus a commerce platform

The two solve different problems, and the decision hinges on exactly that.

Contao is an open-source CMS on a PHP base that you self-host. It comes from the world of websites and editorial, with very good content management and strong multilingual support at its core. But the shop is not part of that core, it’s added through the Isotope eCommerce extension. That’s an important distinction: Contao is a CMS that can also sell, not a selling platform.

Shopify is built for selling from the ground up. The shop is the core, not the add-on. As soon as e-commerce becomes your core business, you need the depth Shopify delivers.

Store2X recommends Richard Roth

I usually frame this as a question of what earns the money. If your Contao site is primarily an editorial presence with an occasional Isotope sale, ripping it out would be a mistake. But once the shop drives real revenue, running commerce through a CMS extension quietly costs you conversions at checkout. In those cases I keep the content strength in mind during migration and rebuild it on Shopify rather than pretending it doesn’t matter.

Cost comparison: what do you really pay?

The two differ fundamentally in their cost model, and the software alone says little.

Contao costs

Contao and Isotope eCommerce are free as open source. Sounds good, but it’s only half the math. On top come ongoing costs that quickly make up the larger part:

• Hosting: Managed hosting for Contao runs roughly €15 to €40 per month.
• Maintenance and upkeep: Updates, Isotope support and security usually run through an agency, scaling with size.
• Development: Many commerce features that come natively elsewhere have to be developed for you.

So the free software masks the total cost of ownership.

Shopify costs

Shopify works with a clear pricing model. The Basic plan costs about €36 per month with annual billing, higher plans are about €105 and €384. Hosting, security and updates are fully included, so there are no separate server or maintenance costs.

Especially dropping the ongoing server and update upkeep makes Shopify more predictable than Contao’s free license suggests at first glance.

Cost comparison in practice

Content and multilingual support: Contao’s big strength

This deserves to be named clearly and fairly: on content management and multilingual support, Contao is outstanding.

Contao is a CMS at its core, and you notice it. Editorial, page structures and above all native multilingual support are among the best open source has to offer. If your website itself is central and content plays the lead role, Contao is hard to beat.

Shopify catches up on content significantly through blog, metaobjects, Markets and apps, and covers multilingual support via Shopify Markets. The difference stays: Contao optimizes for content and editorial, Shopify for selling.

Commerce depth: the Isotope shop at its limits

Here it shows why Contao hits limits quickly for serious selling.

The shop runs through Isotope eCommerce, an extension. That means commerce depth is inherently limited: many payment methods, subscription models, extensive discount logic, B2B or deep multichannel connection are not possible or only with development effort.

Shopify brings all of this natively: practically unlimited products and variants, many payment methods, subscription models via apps, extensive discount engines, B2B, international sales channels and an ecosystem of over 16,000 apps, including German legal and tax apps. As your range and requirements grow, you need this depth.

Checkout and scaling

In the end the checkout decides your revenue.

Shopify’s Shop Pay is considered one of the best-converting checkouts in e-commerce. The Isotope checkout doesn’t keep up, which shows directly in revenue across many orders.

On scaling too, Shopify has the advantage: the platform carries from small shop to enterprise without you hitting product, feature or server limits. With Contao the shop scales only as far as the extension and your server allow.

Maintenance: self-hosting versus a worry-free package

This is one of the biggest differences in daily life.

Contao is self-hosted. That means: you handle the server, security updates, Contao updates and Isotope upkeep, ongoing and usually via an agency. That gives you full control over the code but costs time and budget.

With Shopify the platform handles hosting, security and all updates. You have no server to look after and no update cycles that tie up developer time. This freedom from maintenance is the strongest argument for many Contao merchants, and it mirrors a broader shift: our shop system market study shows self-hosted systems like Contao losing ground (down 7.9 percent from 2024 to 2026) while the market consolidates toward hosted platforms.

SEO and content migration

Both offer strong SEO fundamentals, and Contao users often maintain their content and meta data particularly carefully.

The important point when switching: since you keep your own domain, rankings and content are preserved. We migrate your Contao pages, blog content and multilingual URLs, including images, and cleanly redirect old paths via 301. This way you lose neither your content nor your visibility.

When is Contao the better choice?

Contao makes sense if you:

• Want a content- and editorial-driven website with high standards
• Need strong multilingual support at the core
• Run only a small shop with a manageable range
• Value full code control over open source more than freedom from maintenance
• See selling as a complement, not the core business

Contao is a first-class choice when content and multilingual support are at the center.

When is Shopify the better choice?

Shopify makes sense if you:

• See selling as your core business and need real commerce depth
• Want the best-converting checkout and more payment methods
• Want to get rid of server and update maintenance
• Need unlimited products, subscriptions, B2B or multichannel
• Want to scale and sell internationally

Shopify is the better choice as soon as e-commerce is at the center of your business.

Switching from Contao to Shopify

Maybe your website runs on Contao and you notice the Isotope shop hits limits when selling. Switching to Shopify is then the logical step, without giving up your content or your multilingual support.

The migration from Contao to Shopify transfers products, customers, orders and your pages and blog content. We rebuild your design as a fast Shopify theme and redirect all URLs via a seamless redirect map so your rankings are preserved.

With the right concept, you use the migration as an opportunity: out of the commerce limits and the maintenance load, into real selling power, with your content on board. We at store2x specialize in exactly these migrations to Shopify. If you’re considering whether a switch makes sense for you, you can request a free potential analysis.

Conclusion

Contao or Shopify? It depends on your focus. For content and multilingual support, Contao is one of the best open-source platforms. But as soon as selling is at the center and you want commerce depth, the better checkout and no server maintenance, Shopify is usually the better choice, without giving up your content.

Frequently Asked Questions

Can Contao run an online store at all?

Yes, but only through the Isotope eCommerce extension. Contao is a CMS at its core, the shop is an add-on. That limits commerce depth, payment methods and the checkout compared to a dedicated selling platform like Shopify.

Is Shopify better than Contao with Isotope?

For selling, yes. Shopify offers more payment methods, the best-converting checkout, a huge app ecosystem and no server maintenance. On the pure CMS and multilingual side, Contao stays strong, so the answer depends on your focus.

Do I take my content and multilingual support to Shopify?

Yes. We migrate pages, blog and multilingual content including images and URLs. Shopify covers multilingual support via Shopify Markets, and we redirect old paths via 301 so your content and rankings are preserved.

What does switching from Contao to Shopify cost?

It depends on catalog, Isotope setup, design and content, so there's no flat price. We migrate at a fixed price and watch for clean redirects so your rankings are preserved.

Will my SEO rankings be preserved when switching?

Yes. Since you keep your own domain, we document all URLs including multilingual paths, create a complete redirect map and transfer all meta data. This way your visibility is preserved.
