With so many different open source ecommerce platforms available, figuring out which is right for you is tough. You know you want a customizable and flexible solution for creating and managing online stores—but now need to figure out which tool is best. I've got you! In this post, I'll help make your choice easy, sharing my personal experiences using dozens of different ecommerce platforms with online stores of all sizes, with my picks of the best open source ecommerce platforms overall.

What is an Open Source Ecommerce Platform?

Open source ecommerce platforms are software solutions that allow businesses to build and manage online stores with the freedom to customize and modify the platform to their specific needs. These platforms are built on source code that is freely available for anyone to use, modify, and distribute. This open nature enables a high degree of customization, making it possible for businesses to tailor the platform to their unique requirements, whether it's for design, functionality, or integration with other systems.

Open source ecommerce solutions are particularly favored by businesses looking for a cost-effective, flexible solution that can grow and evolve with their needs, supported by a community of developers who continuously contribute to the platform's development and improvement.

Open Source Ecommerce Platforms FAQ

Start here to address some of the common FAQs related to open source ecommerce platforms.

Open Source Ecommerce Platforms: Comparison Criteria

What do I look for when I select the best open source ecommerce platforms? Here’s a summary of my evaluation criteria: 

  1. User Interface (UI):  Is it clean and attractive? Is the interface clutter-free and organized? Is its arrangement optimized to execute key features quickly?
  2. Usability: Is it easy to learn and master? Does the ecommerce software company offer good tech support, user support, tutorials, and training? Since Open source ecommerce platforms do not usually offer support, this criteria becomes all the more important to distinguish different tools.
  3. Integrations: Is it easy to connect with other tools? Any pre-built integrations? How smoothly does the tool work with other plugins, extensions, and add-ons? There are a variety of ecommerce apps out there designed to plug into your website, so I'm looking for compatibility with most or many of them. 
  4. Value for $: How appropriate is the price for the features, capabilities, and use case? Is pricing clear, transparent, and flexible? Since these are open source ecommerce platforms, the criteria will be about the number of features and ease of use provided for the free price tag.

Open Source Ecommerce Platform: Key Features

What key ecommerce features make the best open source ecommerce platforms? I specifically searched the web for these important features and functionalities:

Increased Flexibility 

Does the platform offer a higher level of customization and flexibility? With open source ecommerce platforms, you can do an unprecedented level of customization due to it being free from the generic SaaS model. I searched different tools for the level of customization they allow and came up with the list below.

Advanced Security 

Does the platform offer a strong security module? Open source ecommerce platform code is analyzed and implemented by a community of focused developers. So any code implemented is filtered through a different set of checks. This gives them security leverage. 

Site Speed 

Does the platform load fast? Does it offer average page-speeds? Site speed is a critical metric to measure when making your ecommerce business go live. Slow speeds can result in drop-offs, lower conversions, and a fall from Google rankings. Based on that, I tested the platforms for their site speed.

Community Support

Does the platform offer any sort of community support? Is there a community offering helpful guides, tutorials, and updates to back the product usage? An open-source ecommerce platform usually does not offer direct 1-on-1 support due to the costs involved in managing it. Having said that, without helpful guides, documentation, and an active community, even the best feature-rich open source ecommerce platform will become a dud.

Also, due to the high-level of technicalities involved, community support is a must. With an active developer community behind the product, the product can see faster evolution and better adaptation to new trends and technologies.
