Artificial intelligence is changing the way ecommerce websites are designed, developed and managed.
For Shopify merchants, the possibilities are exciting.
Tasks that previously required specialist development knowledge can increasingly be completed using AI-powered tools. From generating custom theme sections to writing code, troubleshooting technical issues and suggesting new functionality, AI is making ecommerce development more accessible.
And we think that's a positive development.
Anything that helps brands become more efficient, innovate and improve their online stores deserves attention.
But when it comes to using AI-generated code on a live Shopify website, particularly one generating significant revenue, we believe there's an important conversation that isn't happening often enough.
Just because AI can generate code doesn't necessarily mean that code should be deployed to your live store.
We're following AI developments closely. We can see the opportunities, but we're also conscious of the long-term implications of introducing code that hasn't been properly reviewed, tested and understood.
For us, the questions go beyond whether the code works today.
Who is responsible for it? Where has it come from? How will it interact with future development? And what happens when something goes wrong?
These are the questions we believe Shopify merchants should be asking before introducing AI-generated code into their ecommerce websites.
How Is AI Changing Shopify Development?
AI-powered development tools are making it easier for merchants to customise their Shopify stores without always needing to write code themselves.
For example, Shopify's own AI assistant, Sidekick, can help merchants generate custom theme blocks using natural-language instructions.
Instead of manually developing a new section, a merchant can describe what they want and have AI generate a starting point.
Other AI coding tools can assist with Liquid, HTML, CSS, JavaScript and more complex development tasks.
For businesses that previously needed external development support for relatively simple changes, this could create genuine opportunities.
AI can help with:
-
Generating custom Shopify theme sections
-
Creating and modifying website layouts
-
Troubleshooting development issues
-
Suggesting improvements to existing code
-
Building prototypes and testing new ideas
-
Supporting developers with repetitive tasks
-
Explaining unfamiliar code and functionality
For startups and smaller ecommerce brands, this increased accessibility is particularly appealing.
We understand why.
If a merchant can create a new website feature in minutes rather than commissioning a development project, that's an attractive proposition.
But generating code is only one part of developing a reliable ecommerce website.
Even Shopify Advises Caution With AI-Generated Code
One of the most interesting aspects of AI-assisted Shopify development is that Shopify itself recognises its limitations.
In its official guidance on generating theme blocks with Sidekick, Shopify explains that AI-generated code can contain errors, behave unexpectedly or fail to meet accessibility and performance best practices.
Shopify also makes clear that merchants are responsible for reviewing, testing and ensuring that generated blocks meet their requirements.
Importantly, Shopify states that assistance with customising or troubleshooting AI-generated blocks isn't supported by Shopify Support or third-party theme developers.
You can read this directly in Shopify's guidance on AI-generated theme blocks.
For us, that raises an important question.
If the platform providing the AI functionality is advising merchants to review and test the code, shouldn't we be asking who is qualified to carry out that review?
A merchant might be able to generate a custom section and see that it looks correct.
But will they know whether the code is efficient, secure, accessible and compatible with the rest of their Shopify theme?
That's where we believe human development expertise remains essential.
The Question We'd Be Asking: Where Has This Code Come From?
One of our biggest considerations around AI-generated Shopify code is provenance.
When a developer creates functionality for a Shopify store, there should be a clear process for understanding what has been built, why particular decisions were made and who is responsible for maintaining it.
With AI-generated code, the process can be less transparent.
We know which company provides the AI tool.
But that doesn't necessarily tell us the provenance of every pattern, implementation or approach the tool generates.
AI coding models learn patterns from substantial amounts of training material, which can include publicly available code, documentation and other sources, depending on the model.
That doesn't mean a generated snippet was copied from a particular repository. In many cases, you cannot reliably trace a generated output to one identifiable original author.
And that's precisely what makes provenance an interesting question.
Who has verified that the generated solution is appropriate for your particular Shopify store?
Where has the approach come from? Is it using current development practices? Has the developer or merchant checked whether it's compatible with the existing codebase?
And perhaps most importantly, who takes responsibility if the generated solution causes issues later?
These questions aren't unique to AI. They're important whenever code is introduced into a website.
But AI makes it possible to generate and implement changes at a scale and speed that can exceed the review processes around them.
That's something we think ecommerce brands should consider carefully.
We've Seen What Happens When Developers Build Code on Top of Code
Anyone who has worked on an established ecommerce website will understand this challenge.
Over time, Shopify stores evolve.
A developer introduces a new feature. Another developer modifies the theme. A third adds an integration or changes existing functionality.
Each individual change may appear reasonable.
But without clear documentation, development standards and an understanding of the wider codebase, complexity can accumulate.
Eventually, you can find yourself with a website where relatively simple changes become difficult because nobody fully understands how different components interact.
We've seen the challenges that can arise when multiple developers contribute to the same ecommerce website over time.
And our question is simple.
How is introducing AI-generated code without proper oversight any different?
In some ways, the problem could become more pronounced.
If merchants can generate custom functionality whenever they need it, without understanding the underlying code, they may unintentionally introduce duplicated logic, unnecessary scripts, conflicting functionality or changes that are difficult to maintain.
One generated section might work perfectly.
So might the next.
But what happens after ten, twenty or fifty changes?
Will the theme remain easy to update? Will everything continue working together? And will the next developer understand what has been implemented?
We don't yet know how widespread these long-term problems will become across AI-assisted Shopify development.
But we do know that technical debt is a genuine challenge in software development, regardless of whether the code was written by a human or generated by AI.
The important factor is how that code is designed, reviewed, documented and maintained.
AI Generated Code and Website Security: What About Vulnerabilities?
Security is another area that deserves attention.
Software development has long faced challenges involving insecure code, outdated dependencies and vulnerabilities introduced through third-party components.
The open-source ecosystem provides countless examples of why dependency management, code review and security maintenance are important.
Open-source software itself isn't inherently insecure. Many projects are thoroughly reviewed, actively maintained and essential to modern software.
The concern is what happens when developers introduce code or dependencies without understanding their security implications.
AI-assisted development doesn't remove these risks.
In fact, it can introduce additional considerations.
The Open Worldwide Application Security Project (OWASP) has published guidance covering risks associated with AI-generated code, including insecure implementations, outdated or fabricated dependencies, sensitive information exposure and inadequate human oversight.
See OWASP's guidance on secure coding with AI.
For Shopify merchants, the risks depend on what the generated code actually does.
A simple visual theme block presents a different risk profile from custom JavaScript handling customer information, a third-party integration or an app interacting with sensitive store data.
Not all AI-generated code carries the same level of risk.
However, we believe brands should be particularly cautious when generated code interacts with:
-
Customer information
-
External APIs and third-party services
-
Cart functionality and pricing
-
Product data and inventory
-
Tracking and analytics
-
Authentication or permissions
-
Apps and external dependencies
The point isn't that AI-generated code will automatically create a vulnerability.
It's that a merchant without development experience may not recognise one if it exists.
A Shopify Feature That Works Today Could Create Problems Tomorrow
One of the biggest questions we'd encourage brands to consider is what happens after an AI-generated feature goes live.
Let's say AI creates a new product recommendation section.
It looks great, works correctly on desktop and appears to function on mobile.
The merchant publishes it and moves on.
Six months later, they update their Shopify theme.
Or introduce a new subscription app.
Or change how product variants are displayed.
Suddenly, something stops working.
Perhaps the recommendation section doesn't display the correct products. Maybe it conflicts with existing JavaScript or relies on elements of the theme that have changed.
This isn't a problem unique to AI-generated code. Human-developed customisations can encounter the same issues.
But where proper development processes are in place, there should be a clearer record of what was changed, why and how the functionality is expected to work.
Without that documentation, troubleshooting becomes more difficult.
And for ecommerce businesses, technical issues can have commercial consequences.
A problem with an important product page, add-to-cart interaction or customer journey could affect conversion rates and revenue.
This is why our approach to Shopify website design and development places emphasis on performance, usability, testing and long-term maintainability.
A feature needs to do more than work on the day it's launched.
It needs to fit into a website that will continue evolving.
Could AI Generated Shopify Code Affect Website Performance and SEO?
Absolutely, although the impact depends on the quality and implementation of the code.
AI-generated theme changes can introduce unnecessary JavaScript, inefficient styling, layout shifts or additional third-party dependencies.
These can potentially affect website performance and the mobile shopping experience.
For example, a custom section might look impressive but load unnecessary resources or introduce functionality that slows down the page.
That matters because site performance influences user experience and can affect search performance.
Google uses Core Web Vitals as part of its ranking systems, although good scores alone don't guarantee higher rankings.
From an ecommerce perspective, we also need to think about conversion.
If additional functionality slows down a product page, makes navigation more complicated or creates unexpected behaviour on mobile, the commercial impact could outweigh the value of the new feature.
That's why we believe Shopify development decisions should always consider the wider customer journey, not just the individual feature being introduced.
Whether code is human-written or AI-generated, the same performance and quality expectations should apply.
Does This Mean Brands Should Avoid AI for Shopify Development?
No.
We certainly don't think AI should be dismissed.
In fact, we're excited about how AI could improve efficiency, support developers and make ecommerce innovation more accessible.
There are areas where AI assistance can be incredibly useful.
Helping developers investigate issues, understand unfamiliar code, produce initial prototypes, document functionality and explore possible solutions are all valuable applications.
We also recognise that experienced developers can use AI-generated suggestions responsibly within established workflows.
The distinction we would make is between using AI to assist development and allowing AI to replace the controls that make development reliable.
A qualified developer reviewing an AI-generated solution, testing its behaviour and accepting responsibility for the finished code is very different from a merchant copying code they don't understand directly into a live store.
Those two approaches shouldn't be treated as equivalent.
Our Position at Lionheart: We'd Rather Learn Carefully Than Rush to Adopt
We're watching AI-assisted Shopify development with genuine interest.
We can see the benefits, and we're certainly not against new technology.
But we're also responsible for the Shopify stores and ecommerce businesses that trust us with their development.
For that reason, we're taking a cautious approach to introducing AI-generated code into client production environments.
We're happy to let the wider industry experiment, share findings and demonstrate how these tools perform over time.
That doesn't mean ignoring AI or refusing to explore it in controlled environments.
It means we don't believe being first to adopt every new development capability should automatically be the priority.
We want to understand:
-
How reliable is the generated code?
-
How easily can developers maintain it?
-
What happens when Shopify themes and integrations change?
-
What security and performance risks emerge?
-
How effective are the review and testing processes?
-
What are the long-term implications for businesses with complex ecommerce requirements?
As the technology matures and stronger development practices emerge, our approach can evolve alongside it.
But for now, we'd rather see a robust, well-tested solution than introduce unnecessary risk simply because something can be generated in seconds.
That's not resistance to innovation.
It's recognising that responsible development involves more than speed.
What Should Shopify Merchants Consider Before Using AI-Generated Code?
If you're thinking about using AI to customise your Shopify website, we'd recommend treating generated code with the same care you would apply to code from an unfamiliar developer.
1. Understand What the Code Actually Does
Don't judge a feature solely by its visual appearance.
Understand what has been introduced, what files it changes and whether it interacts with existing functionality.
If you don't have the technical knowledge to assess it, consider getting a Shopify developer to review it.
2. Avoid Making Changes Directly to Your Live Theme
Where practical, use an unpublished duplicate theme or a suitable development environment to test changes.
Remember that theme previews won't reproduce every live-store interaction, particularly where apps, checkout functionality or external systems are involved.
Always test important customer journeys before publishing.
3. Check Performance and Accessibility
Assess generated functionality on desktop and mobile.
Consider its impact on page speed, usability, accessibility and overall site performance.
A visually appealing feature isn't necessarily an effective ecommerce feature.
4. Review Security and Dependencies
Be particularly careful with generated code that references external scripts, requires new packages or connects to third-party services.
Have a qualified developer verify dependencies, permissions and data handling where relevant.
Never paste sensitive credentials or customer information into an AI tool without an approved, secure process.
5. Keep a Record of Changes
Document what was added, where it was implemented and why.
Where appropriate, use version control and maintain a clear rollback process.
This makes future troubleshooting, theme updates and developer handovers easier.
6. Make Sure Someone Owns the Code
Every production change should have a person or team responsible for reviewing, approving and maintaining it.
AI can generate a solution.
But your business still needs someone accountable for ensuring that solution is appropriate.
Frequently Asked Questions About AI Shopify Development
Can AI build a Shopify website?
AI tools can assist with creating Shopify theme sections, writing code, generating content and supporting development tasks. However, building a reliable ecommerce website also requires decisions around user experience, SEO, integrations, accessibility, performance and testing.
Is AI generated Shopify code safe?
AI-generated code isn't automatically safe or unsafe. Its reliability depends on the implementation, the functionality involved and whether it has been appropriately reviewed and tested. Shopify advises merchants to review generated theme blocks before publishing.
Can AI generated code slow down a Shopify store?
Yes, poorly implemented generated code can introduce unnecessary scripts, inefficient functionality or other performance issues. However, well-reviewed AI-assisted code can also be efficient. Performance testing is important regardless of who or what generated the code.
Can AI generated code affect Shopify SEO?
Potentially. Changes that affect rendering, navigation, internal links, page content, structured data or performance may influence how search engines access and understand a website. The impact depends on the particular implementation.
Should I use AI instead of a Shopify developer?
For simple tasks, AI tools may help merchants accomplish changes without commissioning development work. However, specialist expertise remains valuable for complex functionality, security-sensitive work, integrations and important ecommerce journeys.
Who is responsible if AI generated code causes problems?
The merchant or development team implementing the code remains responsible for reviewing, testing and maintaining it. Using an AI tool does not automatically transfer responsibility for the finished implementation to the AI provider.
Can Shopify developers use AI responsibly?
Yes. AI can support experienced developers with prototyping, debugging, documentation and code suggestions. The important distinction is ensuring the generated code is understood, reviewed and tested before being introduced into production.
Our Final Thoughts: AI Can Write Code, but Who Is Responsible for What Comes Next?
AI is creating exciting opportunities for Shopify merchants.
It has the potential to make ecommerce development more accessible, improve productivity and help businesses experiment with new ideas.
We welcome that.
But we also believe brands should look beyond the immediate convenience of generating functionality in seconds.
The important questions aren't simply whether AI can build something or whether the result looks good.
They're whether the code is appropriate, maintainable, secure and compatible with the wider ecommerce environment.
We've already seen the challenges that can arise when different developers repeatedly add functionality without a clear understanding of the existing codebase.
We don't believe AI should be exempt from those same concerns.
If anything, its ability to generate code so quickly makes proper review, documentation and accountability even more important.
Our position is simple: we're excited by AI, but we're not prepared to compromise the long-term stability of our clients' Shopify stores just to be first to adopt something new.
We'll continue learning, monitoring developments and evaluating opportunities as the technology evolves.
But we'll always prioritise building ecommerce experiences that are reliable, maintainable and focused on commercial performance.
Because ultimately, brands don't need more code.
They need better performing ecommerce stores.
