Alokai (Formerly Vue Storefront) vs. Spartacus: Which Headless Frontend is Better?

Feb 28th, 2024 13 min to read

Building an online store that’s fast, flexible, and future-proof is what every eCommerce merchant dreams of.

Thanks to headless commerce, where the presentation layer (UI) dances separately from the backend (commerce engine), there is a way to make your dream true. But for that, you need a comprehensive storefront like your existing eCommerce platform “SAP Commerce Cloud”.

And when it comes to choosing your headless frontend, two contenders rise above the rest: Alokai (Formerly Vue Storefront) and Spartacus (SAP Composable Storefront).

I know, the challenge of picking the right headless frontend is tough as you already have “Spartacus” – a dedicated option for your headless backend. But, don’t worry!

This blog will be your ultimate guide to navigating the “Alokai (Formerly Vue Storefront) vs. Spartacus” battlefield. We’ll delve deep into their strengths, weaknesses, and unique features that will help you to make an informed decision for your next headless SAP Commerce Cloud store.

Let’s start with the basics!

Headless Frontend 101

Headless Frontend

Frontend is simply the user interface of a website that the visitors can see and interact with. With the arrival of the Headless approach, the frontend is no longer tied to any specific backend technology.

Instead of directly generating the website’s content, the backend exposes its data and functionality through APIs (Application Programming Interfaces). These APIs act as messengers, carrying information back and forth between the frontend and backend.

Now, you’re not limited to pre-built themes or templates with your traditional eCommerce platforms, i.e. SAP Commerce Cloud. Headless frontend solutions allow you to craft a unique storefront that seamlessly integrates with any backend system.

For example: You want to add a personalized product recommendation carousel to your homepage. In a traditional or monolithic architecture, this would involve backend developers tinkering with the core source code. With headless commerce, the frontend team simply builds the carousel using the product data API, seamlessly plugging it into the existing UI.

You can choose any Frontend tool or framework you like to build the website’s visual elements, like React, Vue, or Angular. This gives you more flexibility and freedom to create unique and engaging user experiences.

Let’s meet the contenders in the ring!

Spartacus (SAP Composable Storefront)

Spartacus, now officially known as SAP Composable Storefront, is not just a storefront; it’s a headless, composable, and open-source framework powering modern ecommerce experiences for SAP Commerce Cloud (SAP CC).

Built on Angular, Spartacus separates the frontend presentation layer from the backend commerce engine that works independently on the decoupled architecture.

Spartacus (SAP Composable Storefront)

While no longer an open-source project, its legacy lives on as the core of the official SAP Composable Storefront (version 5.0). This newer iteration is specifically tailored for B2B eCommerce, packing features like Multi-Site Data Isolation, B2B Unit-Level Orders, and Account Summaries.

So, what happened to the original Spartacus? While the 4.x version is no longer publicly available, its essence remains alive within the new composable commerce storefront technology. 

As a SAP Commerce Cloud user, you have a choice: adopt the official B2B-focused version or explore alternative composable storefront solutions from other vendors. Ultimately, the decision rests on what fits your business needs best.

Key Features

  • Headless Architecture: Decouples the front-end (Spartacus) from the back-end (SAP Commerce Cloud) via REST API, enabling independent development and deployment.
  • Angular Framework: Utilizing Angular as its base, Spartacus provides a robust and feature-rich framework for building performant and dynamic storefronts.
  • Component-based UI: Build your storefront using pre-built and customizable UI components like product listings, carts, and checkout flows.

Pros of Spartacus Storefront

Made for SAP Commerce Cloud exclusively: For existing SAP users, Spartacus offers a seamless connection with the backend, leveraging existing features and data through the familiar Commerce REST API.

  1. Strong B2B Capabilities: The B2B-focused version excels with features like Multi-Site Data Isolation, Unit-Level Orders, and Account Summaries, making it ideal for complex B2B scenarios.
  2. Headless Architecture for Scalability: Although not truly headless, the API-driven nature allows for separate deployment cycles and scalable frontends.
  3. Improved Developer Experience (DX): Version 5.0 introduces features like lazy loading and code splitting, enhancing developer experience compared to earlier versions.
  4. Open-Source Core (4.x): While the latest version is not open-source, the core of Spartacus remains available on GitHub, fostering community contributions and potential future forks.
  5. Reduced Development Time: Spartacus offers pre-built storefront templates and accelerators, potentially speeding up development for common B2B functionalities.

Cons of Spartacus Storefront

  1. Steep Learning Curve: The Angular-based tech stack presents a learning curve for merchants, requiring expertise that can be expensive and time-consuming to acquire.
  2. Limited Customization Flexibility: The prebuilt storefront design restricts deep customization, forcing merchants to choose between minor tweaks or potentially rewriting the entire codebase.
  3. Not Truly Headless: Despite appearances, Spartacus’s monolithic design and reliance on SAP solutions limit integration options, hindering true headless commerce flexibility.
  4. Vendor Lock-in: Dependency on SAP Commerce Cloud creates a vendor lock-in scenario, making it difficult and potentially costly to migrate to other eCommerce platforms in the future.
  5. Closed-Source Nature of Newer Version (5.x): The restricted access to the latest version of Spartacus limits transparency, community contributions, and independent learning opportunities.
  6. Potential Performance Bottlenecks: The use of Angular, while powerful, can introduce performance considerations, especially for resource-intensive B2B applications.
  7. Limited Community Support (Newer Version): With the new version being private, community support and troubleshooting resources might be less robust compared to the open-source 4.x version.
  8. Closed-source B2B version: The new B2B-focused version is exclusive to SAP Commerce Cloud customers, thus eliminating open-source access and customization opportunities.
  9. Alternatives with More Flexibility: Other composable storefront solutions might offer greater flexibility in customization, headless architecture, and integration options.

Spartacus’s Pricing

Spartacus comes at no cost for SAP Commerce Cloud merchants. However, development costs can be there based on the complexity of your project and the level of customization required.

This comparison will help you understand which platform might be a better fit for your needs across key factors:

Headless Architecture

Headless Architecture

Both Alokai (Formerly Vue Storefront) and SAP Spartacus are headless commerce platforms, which means that they separate the front-end (the user interface) from the back-end (the business logic). This allows for greater flexibility and scalability, as you can use any front-end framework you like with either platform.

However, there are some key differences between the two platforms in terms of their headless architecture. Alokai (Formerly Vue Storefront) is a pure headless platform, which means that it does not have its own back-end. This means that you will need to integrate it with a separate back-end system, such as Magento or Shopify.

SAP Spartacus, on the other hand, is a partial headless platform, which means that it has its own back-end system, and you cannot use a different back-end system than SAP Commerce Cloud.
