Choosing the Right E-Commerce Platform To Develop an App For [Guide]

Throughout the past several years, web development has become one of the most sought-after technology-based skills. Many web developers choose to work on a freelance basis, especially now when working from home is more popular and necessary than ever.

Many web developers choose to host their apps, plugins, or extensions on the marketplaces for different e-commerce platforms. This immediately gives them a substantial audience to get their apps in front of, all but ensuring numerous downloads every month.

However, with so many e-commerce solutions available today, it can be difficult to find the platform that will work best for you and your products. There are many factors to take into consideration, and researching every available platform is often time-consuming and tedious. 

That’s why we’ve compiled a list of everything you should consider when deciding which marketplace you’ll sell your apps and plugins on. Don’t get bogged down on the details — focus on the few things that really matter. Keep reading to learn what information you should be looking into, as well as some of the best e-commerce platforms for developing apps, plugins, widgets and more!

Things To Consider When Choosing an E-Commerce Platform

Before you decide which platform you want to develop apps, plugins, or extensions for, it’s good to look at all your options and compare a few important factors. Some of the important things you’ll want to make sure you look at include:

  • Price/cost (opening an account, transaction fees, revenue share)
  • Developer support available
  • Development language and framework knowledge requirements
  • Number of users (stores and active users) on the platform
  • Any additional requirements or restrictions for developers
  • Marketplace size and monthly downloads 
  • Additional services and tools for developers

Let’s discuss what each of these factors involve, as well as what you should be looking for. 


Money is king in almost all situations, and web development is no different. For this reason, make sure to consider factors like:

  • Revenue share
  • Transaction fees
  • Any costs associated with opening a developer account

Ideally, you’ll be looking for a platform that allows you to open a developer account and host your apps for free. However, be sure to take revenue share into account, as well. Your revenue share is the percentage of your sales that goes directly to your pocket. Most platforms give you between 60%-80% of your total sale amount, then take the rest as a fee. In addition to this, some marketplaces charge a separate fee for each transaction. 

Since you’re likely to make a sale more often than you have to pay a membership fee, it may be worth it to opt for a higher account cost in return for a higher revenue share or fewer transaction fees. It all comes down to personal preference and what you can afford.

Things can get complicated when you develop an app, plugin, or extension for use on a specific e-commerce platform. For this reason, it’s important that whatever marketplace you choose offers adequate support for developers. 

All the resources you need should be easy to access, including information regarding the system’s API. If you cannot easily find developer support topics on the platform, if the site requires payment before you can access them, or if help topics are buried pages-deep, you may want to look elsewhere.

While the available support materials will vary by platform, they should generally include:

  • Video tutorials
  • Various documents
  • Some kind of developer community

Having sufficient support from your chosen platform, as well as from other developers, will help you significantly among your development journey.  

Development Language/Framework Knowledge Requirements

Different platforms work with different development languages and frameworks. If you find an e-commerce platform that you want to start developing apps for, make sure you’re familiar with their programming languages before signing up.

This information can generally be found in the API documents or other developer resource pages. Some of the most popular languages across e-commerce platforms include:

  • JavaScript
  • Python
  • #C
  • Java

Make a list of the development languages and frameworks you’re currently familiar with, and look for platforms that use them. If you’re particularly dedicated to a certain platform, you may even want to consider learning a new language! 

Number of Platform Users

When you develop an app, you want to be sure you can get it in front of enough people to maximize your sales. For this reason, it’s important to ensure that there is a sufficient number of users on the platform you choose. 

Make sure to not only look at the number of active users on a platform, but the number of sites they host, as well. More websites mean more opportunities for webmasters to purchase and install your apps, plugins, or extensions. 

Other Requirements or Restrictions

Before you choose a platform, it’s important to find out what (if any) restrictions or requirements you will have to adhere to while developing for them. Some platforms don’t allow certain types of apps and extensions, while others will require a specific user interface or experience. 

Always read any developer documents or agreements completely and thoroughly before you commit to developing on a certain marketplace. If they impose any restrictions or requirements that your apps do not align with, move on to the next platform. 

Marketplace and Monthly Downloads

The size of a platform’s app marketplace is of utmost importance. The more apps there are available, the more competition you will typically have. Consider how many apps there are altogether, how many of those are similar to yours, and the marketplace’s average number of monthly downloads. 

A high number of overall apps indicates that the platform is reliable, fair, and secure. However, you don’t want to add your apps or extensions to an already saturated marketplace! Look up keywords related to your apps and plugins, and see if you’ll have any direct competition on the platform. The fewer apps that are competing with yours, the better. 

If possible, finding out the average number of monthly downloads on a marketplace can be helpful, as well. Make sure this number is high enough to make you feel confident in your app’s ability to turn a profit. 

Additional Services

While not completely necessary, it’s always better to work on a platform that offers additional services, such as marketing and promotion support, for their developers. Some platforms will show different apps and extensions on their “Featured” page daily, weekly, or monthly, which all but guarantees additional downloads for you. 

Some marketplaces will also offer you the choice to add a paid promotion to your apps. The fees to do so are generally low, and these promotions are often effective in getting you additional downloads.  


The final thing you should look for when browsing e-commerce platforms is any tools that improve the app-building process. Does that platform let you open a “sandbox account” for testing purposes? Do they offer community forums and events for their developers? 

It’s best to develop for a website that has a dedicated Developer Center. These pages are typically full of resources and tools to help you and other developers create the best, most responsive apps and extensions possible. Having tools like these available not only shows that the platform respects you as a developer, but it also shows their commitment to hosting the best-possible extensions.
