Back to Outperform

Choosing the perfect experimentation platform can be overwhelming, especially with options like VWO, Optimizely, Eppo, and many others vying for your attention.

Let's dive into a quick comparison of these platforms to help you make an informed decision.

We’ll be highlighting their features, strengths, and weaknesses — guiding you toward the best fit for your needs in our final verdict. 

VWO vs. Optimizely vs. Eppo: Head-to-head

VWO

__wf_reserved_inherit

VWO is a well-established platform that's been around in the A/B testing and experimentation space for quite a while. Originally named “Visual Website Optimizer”, the India-based company has offered a website A/B testing tool for marketing teams since 2009. 

VWO provides marketing teams with a broad toolkit for enhancing their websites, mobile apps, and other digital touchpoints. It is known for offering a mix of experimentation and broader marketing analytics features.

VWO has several notable features:

  • A/B and multivariate testing: VWO lets you test different versions of your website or app to figure out what works best for your audience and goals. It can handle simple A/B tests as well as more complex multivariate tests.

  • Full suite of marketing tools: Beyond experiments, VWO offers a variety of tools like heatmaps, surveys, and funnel analysis (understanding how users move through your site). This gives you a broader view of user behavior.

  • Add-on products: VWO has expanded its offerings with add-ons like VWO Data360, a customer data platform that can be useful if you don't already have one. This lets you gather and manage customer data for more targeted actions.

  • Hands-on support: VWO's India-based team also sells professional services that provide active support to customers, helping them plan and execute their optimization strategies.

Pricing

VWO's pricing can be a bit tricky to understand at first glance. It's based on the number of Monthly Tracked Users (MTU), which means the cost goes up as you have more visitors to your site or app. 

They do have a free version for smaller businesses with under 10,000 unique visitors, but the more advanced features are found in the paid plans. These can get quite pricey, especially if you add on extra products like the data platform.

Who is it good for?

VWO might initially appeal to those seeking an all-in-one platform that goes beyond basic A/B testing, offering a suite of marketing analytics tools under one roof. 

If you're building your marketing toolkit, the promise of having heatmaps, surveys, and funnel analysis alongside your experimentation could be attractive. VWO's dedicated support team could also be a plus, especially for teams new to experimentation.

However, be prepared for some potential hurdles. While the add-on system offers flexibility, it can quickly escalate costs, and overall the suite of tools focuses more on breadth and depth, with few advanced features available in each tool.

VWO's interface has also been described as less intuitive compared to some newer tools, which might mean a steeper learning curve. And while the hands-on support is appreciated by many, some users might prefer a more self-serve approach with simpler tools.

Optimizely

Optimizely is a Digital Experience Platform (DXP) designed to empower marketing and product teams to refine their digital presence across various channels, including websites, mobile apps, and more.

The modern Optimizely company is a combination of many older SaaS players, including the original Optimizely experimentation software, the Episerver CMS, and other marketing operations tools like Welcome and a CDP. 

Optimizely's key features include:

  • Feature experimentation: Optimizely lets companies roll out new features gradually to specific user segments, testing their impact and gathering feedback before a full-scale launch.

  • A/B and multivariate testing: Like VWO, Optimizely enables businesses to experiment with different variations of their web pages or app features to identify what resonates best with users and drives more engagement and conversions.

  • Content Management System (CMS): Optimizely lets users easily create, manage, and publish content across different platforms, maintaining a consistent brand image.

  • Marketing orchestration: With Optimizely, you can automate and create marketing campaigns across channels to deliver timely and relevant messages to your target audience.

Pricing

Optimizely's pricing isn't publicly disclosed, so potential customers must reach out for custom quotes. 

It's known, however, that Optimizely mainly caters to enterprises, meaning its pricing likely reflects a significant investment, potentially out of reach for smaller businesses or those with limited resources.

Another cost consideration is having to purchase separate products for different testing environments, such as websites, mobile apps, and server-side applications. This fragmented approach can further inflate costs and introduce complexities in managing experiments across different platforms.

Who is it good for?

Optimizely may appear attractive to large enterprises with substantial resources and a complex digital landscape. Its features can indeed be valuable for teams seeking to optimize every facet of their digital experience, from content and experimentation to personalization.

However, Optimizely's complexity and enterprise-focused pricing model make it less suitable for smaller organizations or those with limited budgets. The platform's learning curve can be steep, requiring significant time and expertise to fully utilize its capabilities. 

Additionally, the lack of integrations with external business tools, especially those providing deeper insights into business metrics, can hinder a thorough analysis of experiment impact and limit ROI.

  • Optimizely: Geared towards enterprise clients, Optimizely's custom pricing is often a significant investment, potentially out of reach for smaller companies or those with tighter budgets.

  • Eppo: Though pricing isn't publicly available, Eppo is generally considered a more cost-effective solution, especially when considering its robust experimentation capabilities and direct data warehouse integration.

Ease of use and integrations

  • VWO: Some users have reported that VWO's interface can be less intuitive compared to other tools, and the complexity of its pricing structure might require some getting used to.

  • Optimizely: The extensive range of features within Optimizely's platform can sometimes feel overwhelming, especially for users who are new to experimentation. Additionally, its limited integrations with external business tools might pose challenges.

  • Eppo: Eppo boasts a clean, intuitive interface designed for users of all technical levels. Its seamless integration with popular data warehouses simplifies setup and ensures you're always working with accurate and up-to-date data.
