Open source vs. SaaS ecommerce platforms: Top choices and which is best for you

The debate between open source vs. SaaS ecommerce platforms is an ongoing discussion that’s been around for decades. Almost as long as ecommerce platforms have existed.

Both open source and SaaS platforms have advantages and disadvantages. The decision to pick one over the other usually comes down to use cases, business goals, and individual preferences.

In this guide, I’ll dive into open source and SaaS ecommerce platforms to help you understand what they are, their pros and cons, top choices, and key differences. I’ll also break down the total ownership costs for open source vs. SaaS solutions so you can decide which is best for you.

Let’s start with the basics.

What is an open source ecommerce platform?

An open source ecommerce platform is any software that enables building and managing an online store and provides unrestricted access to its source code. That ensures you can use, modify, and distribute the software for free.

Open source ecommerce platforms are developed and maintained by a community of developers. They’re usually distributed under licenses such as the GNU General Public License or MIT License.

Pros of open source ecommerce platforms

Now that you understand open source ecommerce platforms, let’s discuss their advantages.

1. Transparency and customizability

Open source software provides access to its source code, allowing developers to view, modify, and customize the software to suit their needs. This transparency gives you greater control over your store and the flexibility to customize its design and functionality to your needs.

2. Community-driven collaboration

Open source projects often have active communities of developers who contribute to the software’s development, improvement, and bug fixing. This collaborative effort leads to faster innovation.

3. Accessible pricing

Most open source projects are available for free. That significantly reduces upfront costs for small businesses. Although you need to ecommerce hosting and maintenance, you can control costs much more effectively with open source software.

4. No vendor lock-ins

One of my favorite things about open source software is that you aren’t tied to a specific vendor. That means no worrying about forced payment processors or shipping providers. You can choose services and providers that best suit your business needs.

Cons of open source ecommerce platforms

Open source software has a lot of strengths. But it’s not all sunshine and rainbows. Let’s look at some disadvantages of using open source ecommerce platforms.

1. Needs technical expertise

Setting up and maintaining an open source ecommerce platform requires some technical proficiency. Without those skills, you might struggle with basic tasks like setting up your store, troubleshooting issues, and protecting your store from hackers.

2. Steeper learning curve

The amount of customizability open source platforms offer can intimidate some users, especially beginners. You need to put more effort into setting things up correctly. If you don’t have prior experience with the platform, that can slow your progress.

3. Limited support options

Open source projects usually lack dedicated customer support. You’re often limited to forums like StackExchange or Reddit to find help. While that’s perfectly doable for minor issues, it can be inconvenient when dealing with a time-sensitive matter.

4. Ongoing Maintenance

With open source ecommerce platforms, you’re in charge of ongoing maintenance, unlike SaaS platforms that streamline most of the process. That means greater downtime and chances of things going wrong if you don’t know what you’re doing.

What is a SaaS ecommerce platform?

SaaS ecommerce platforms, or closed-source ecommerce platforms, are proprietary software that let you build and manage an online store without dealing with hosting, maintenance, or security. They require a license and are generally offered as a subscription service.

SaaS platforms are more beginner-friendly but much less customizable than open source platforms. That’s because they give you helpful defaults to simplify building your online store and handle all the software maintenance and optimization so you can focus on your business.

Pros of SaaS ecommerce platforms

Now that you have a basic understanding of SaaS platforms, let’s look at their benefits.

1. Ease of use

SaaS platforms are more user-friendly to set up and maintain. Their interfaces are designed to help beginners get an online store up and running as fast as possible and to make it easy for non-technical users to manage everyday tasks.

2. Small learning curve

Thanks to their simple design, SaaS eCommerce platforms are easier to learn. Whether you’re a seasoned pro or a first-time store owner, you’ll quickly get the hang of things — no need for expensive courses or professional help.

3. Access to support

The best part about SaaS ecommerce platforms is that they offer 24/7 customer support. If you hit a snag or need guidance, help is just a chat, email, or phone call away. You’re never alone in figuring things out — they’ve got your back.

4. Short term cost efficiency

SaaS platforms work on a subscription basis. You pay as you go, so you’re not faced with high upfront costs. You can manage your expenses better and invest your money into inventory and marketing instead of paying a programmer to set up your store.

Cons of SaaS ecommerce platforms

Despite some compelling strengths, SaaS platforms aren’t perfect. Let’s look at the downsides of using a SaaS ecommerce platform.

1. Limited control and customizability

SaaS platforms set you up with helpful defaults to simplify setting up your store. That limits your ability to customize and personalize your online store and offer customers a unique shopping experience.

2. Data ownership concerns

When using a SaaS ecommerce platform, your store and customer data live on the platform’s server. If the platform decides to suspend or ban your account, you could lose access to all your data overnight and need to start again from scratch.

3. Dependence on provider

Another common downside with SaaS platforms is that you depend on the provider for performance and uptime. You can’t do solve issues like slow page load speeds or random HTTP errors yourself.

4. Vendor lock-in

Vendor lock-in is the biggest downside of using SaaS platforms. Many SaaS platforms force users to use specific payment gateways or pay a small commission on their sales if they use a third-party payment gateway.

Top 5 SaaS ecommerce platforms

Want to build an online store with a SaaS website builder? Here are the top five SaaS ecommerce platforms you can use in 2026.

1. Shopify

Shopify is the best SaaS ecommerce platform in the world. It’s easy to use, offers a massive selection of design templates, and has a huge app ecosystem that helps you customize your store functionality without learning code.

Shopify also integrates with leading social media platforms and third-party tools and services. So, no matter which platforms you’re selling across, Shopify will integrate effortlessly and help you easily build on your existing success.

Key Shopify features:

• Dropshipping integration.
• Multilingual storefronts.
• Mobile app for managing your store on the go.
• Point of sale (POS) system for brick-and-mortar stores.
• Automatic tax calculations.
• Customizable checkout process.

Best SaaS ecommerce platform for: B2C, D2C, and small businesses that need a fully-managed ecommerce platform.

Shopify price: Ecommerce store hosting plans start from $39 per month.

2. BigCommerce

BigCommerce is an excellent SaaS platform for building an online store without any technical skills. The best way to describe it would be as a blend of Magento’s scalability and Shopify’s ease of use.

BigCommerce supports 55+ payment providers and popular shipping services by default. You don’t need to worry about additional fees even if you use a third-party payment gateway. I recommend BigCommerce for online stores making more than $500,000 a year.

Key BigCommerce features:

• Unlimited products and staff accounts.
• Multi-store support for all plans.
• Built-in support for marketplaces like Amazon, eBay, and Walmart.
• Built-in Facebook and Instagram sales channels.
• Useful marketing tools.
• Multiple security measures with PCI compliance.

Best SaaS ecommerce platform for: Small and medium businesses selling across multiple channels.

BigCommerce price: The BigCommerce Standard plan starts from $39 per month for businesses with an annual turnover of up to $50,000.

3. Squarespace

Squarespace is one of the best SaaS website builders for creating an attractive online store on a budget. It’s a lot like Shopify with features like support for unlimited products, a code-free design tool, and a Point of Sale app for iOS, but with more attractive design options.

Squarespace offers helpful marketing tools like gift cards, social integrations, and subscriptions with the Commerce Basic and Commerce Advanced plans. If you don’t need advanced ecommerce features and have a small inventory, I recommend considering Squarespace.

Key Squarespace features:

• Useful merchandising features.
• User-friendly inventory dashboard with support for low-stock notifications.
• Built-in support for USPS shipping labels.
• Flexible delivery options, including local pickup.
• Clean checkout with support for Stripe, PayPal, and Afterpay.

Best SaaS ecommerce platform for: Artists and Etsy sellers looking to upgrade to their own store and ecommerce businesses selling digital products.

Squarespace price: Ecommerce plans start from $33 per month plus a 3% transaction fee. Higher plans offer more features with a 0% transaction fee.

4. Wix

Wix is an excellent alternative to Shopify for small online stores. It’s easy to use, offers over 500 design templates, and gives you free access to millions of high-quality images. In other words, the perfect SaaS ecommerce builder for dropshipping and membership stores.

What I like about Wix is that it doesn’t paywall its features as much as other SaaS platforms on this list. It supports multichannel sales, global retail, multiple currencies, and 80+ secure payment gateways.

Key Wix features:

• Supports 90+ languages.
• Exclusive member accounts.
• Multichannel inventory management.
• Product subscriptions.
• Smart business automation.
• Capable of supporting up to 750 transactions per second.

Best SaaS ecommerce platform for: Dropshipping stores, events companies, blogs, and luxury stores with small inventories.

Wix price: Ecommerce plans start from $27 per month.

5. Webflow

Webflow is one of the best SaaS ecommerce platforms for brands that want unique designs. It lets you design a website without code and turns it into clean HTML5, CSS3, and JavaScript code. It’s like having an in-house web developer helping you design your store.

Webflow is built for a very specific audience — design-focused brands. You need a basic understanding of web design to make the most of it. Though if you have a small store and are willing to put in the work, you’ll enjoy Webflow’s design experience.

Key Webflow features:

• One-of-a-kind code-free designer.
• Complete branding control across the website and checkout.
• Gated content for customers.
• Fully customizable schema and SEO markups.
• Custom fields for products.
• Customized checkout flows.

Best SaaS ecommerce platform for: Design-led ecommerce brands with small catalogs like luxury brands.

Webflow price: Ecommerce-capable plans start from $29 per month with support for up to 2,000 products.

Key differences Between Open Source and SaaS ecommerce platforms

Still confused about which is better, open source or SaaS ecommerce platforms? Here’s a side-by-side comparison table to help you decide:

Open source platforms offer more control and flexibility but require technical expertise and more effort to set up. On the other hand, SaaS platforms are easier to set up and manage. Still, they come with limited customizability and control.

Don’t worry. I’ll help you choose between the two in a bit. First, let’s quickly explore the costs of building and running ecommerce stores using open source and SaaS builders.

SaaS vs. open source ecommerce: Total costs of ownership compared

Cost is an extremely important factor in choosing the right ecommerce platform. You can’t choose between open source vs. SaaS ecommerce platforms if they aren’t in your budget.

Let’s examine the costs incurred when using open source and SaaS ecommerce platforms.

1. Subscription fees

• Open source: Typically, open source platforms do not have subscription fees for using the software itself. They’re free to download and use.
• SaaS: SaaS platforms have subscription fees that cover software usage, hosting, updates, security, and often basic support. Subscription fees for SaaS ecommerce platforms like Shopify start from $39 per month and go up to $399+.

2. Hosting fees

• Open source: You are responsible for hosting an open source ecommerce platform. The costs may vary based on the chosen hosting provider, server capacity, security measures, and performance requirements. On average, you can spend anywhere from $20+ for a WooCommerce store to $50+ for Magento hosting.
• SaaS: Hosting costs are included in your subscription fee for your SaaS ecommerce platform. You don’t pay anything extra for hosting.

3. Design customization

• Open source: Open source platforms offer many customization options, but using them may require technical skills. Paid themes can cost $100 to $200, and development costs upwards of $37 per hour.
• SaaS: SaaS platforms provide code-free design tools, but advanced design or layout changes might require professional help. Paid themes may cost around $200, and professional assistance upwards of $50 per hour.

4. Extensions

• Open source: The costs for extensions can vary depending on the platform and type of extension. WooCommerce plugins cost around $99 on average, whereas Magento extensions may cost upwards of $199.
• SaaS: Apps and plugins for SaaS platforms tend to cost more. For instance, apps from the official Shopify store can cost anywhere from $5 to $50+ per month.

5. Maintenance and upgrades

• Open source: Maintenance and upgrades for open source platforms can cost anywhere from $500 – $1,500 or more when outsourced.
• SaaS: Basic maintenance and platform upgrades are free of charge with all SaaS ecommerce platforms.

6. Technical support

• Open source: Open source platforms are supported for free across different forums. Paid support options usually start from $500, depending on the scope of services.
• SaaS: Platform-specific technical support is included free of charge with SaaS platforms.

Here’s a comparison table for the estimated annual ownership costs for open source vs. SaaS ecommerce platforms:

I haven’t included payment gateway fees in the above ownership costs as those vary greatly between platforms, payment gateways, and methods.

Those numbers are estimates to help you understand how much you can expect to spend on building an online store with SaaS or open source software. You might not need some of those, which can further reduce your costs.

I’ve written a detailed article breaking down the costs of an ecommerce website. Make sure you give that a read if you need help calculating how much your online store will cost.

Open source vs. SaaS ecommerce platforms: How to choose the right platform for your online store

Choosing between open source vs. SaaS ecommerce platforms requires careful consideration of your business’s needs, resources, and goals.

Here’s a detailed step-by-step guide to help you make an informed decision:

1. Evaluate your business needs: Understand your products, target audience, and business goals. Consider factors like the scale of your business, sales volume, and growth projections.
2. Consider your technical skills: Think about your technical skills. Are you comfortable with coding or prefer a more user-friendly platform?
3. Determine your budget: Calculate your budget, including initial setup costs, ongoing expenses, and potential customization costs.
4. Check your customization requirements: Assess how much customization you need. Open source offers more customization potential, but SaaS platforms provide simplicity.
5. Consider the time to market: Consider how quickly you need to launch your store. SaaS platforms usually have faster setup times due to their pre-built nature.
6. Prioritize your long-term goals: Evaluate your growth plans. Will your chosen platform accommodate your future expansion needs? Select a platform that fits your current needs and allows growth without excessive technical constraints.
7. Compare essential features: List all the features you need for your online store. Compare these against the offerings of open source and SaaS platforms.
8. Determine the level of support you’ll need: Consider your need for technical support. Are you comfortable troubleshooting issues independently, or do you require dedicated support?
9. Assess security and compliance: If your business handles sensitive customer data, consider each platform’s security and compliance features.
10. Consider integration capabilities: Have a custom POS or ERP system? Or perhaps want to integrate your store with a CRM? You’ll need a reliable API for those. So make sure you compare integration support.
11. Speak to experts: If you’re unsure, seek advice from ecommerce consultants, industry peers, or experts who can provide valuable insights based on their experiences.
12. Check real-world user feedback: Read reviews, testimonials, and case studies from businesses like yours to gain insight into how each platform performs in real-world scenarios.
