There are so many different A/B testing tools out there that choosing the best one for you can be tricky. You want to identify the most effective design or content changes by systematically comparing variations and continuously improving the user's experience with your products but need the right tool for the job. I've got you covered! In this post, I leverage my experience in product management using many different platforms with larger teams, and complex products to share my picks of the best A/B testing software.

What Is A/B Testing Software?

A/B testing software is an online tool that enables you to run controlled experiments on two versions of an idea (web page design, product feature, marketing flow, etc.) to determine the better-performing variant. Through experiment setup and management, statistical analysis, integration with analytics tools, and the ability to test variations of elements such as headlines, images, or call-to-action buttons, it helps you better understand user preferences.

You can use A/B testing software to decide which idea yields the best results regarding user engagement, conversions and other metrics.

Founded in 2012, Kameleoon has evolved into a comprehensive experimentation platform. Kameleoon offers personalization, full stack and A/B testing features to improve engagement and conversion rates. 

Why I picked Kameleoon: I’ve experienced the flicker effect on some ecommerce websites I visited. The flicker effect aka Flash of Original Content (FOOC) is when your original web page “flickers” for a moment before the control page loads. This severely impacts your user experience and may even increase website bounce rates. Kameleoon features an “anti-flicker snippet” functionality that ensures your website experience is entirely flicker-free.

Kameleoon offers the flexibility of a graphic editor and a coding editor (for the technically proficient). Additionally, Kameleoon offers a robust Chrome extension for creating experiments on the fly. 

Kameleoon Standout Features and Integrations

One standout feature includes custom business goal definition. You can predefine test criteria that align with your business goals and objectives. As a result, you can track A/B test success for various elements like CTA button text, hero image, headline copy, etc.

Integrations include over 30 integrations with tools like AT Internet, Amplitude, Contentful, Contentsquare, Crazyegg, Frontastic, Git, FullStory, Hotjar, Heap, and Klaviyo. You can also access thousands of additional apps by connecting it to Zapier.

Pros and cons


  • Dedicated CSM
  • Easy to launch A/B tests

With over 10000 customers, Optimizely has three broad product pillars: Orchestrate, Experiment and Monetize. The A/B testing features fall under the Experient product category.

Why I picked Optimizely: As a former product manager, I recall having a constant see-saw of dilemmas when it came to product feature prioritization. Optimizely has an amazing targeted rollout to progressively release new features. 

With targeted rollouts (aka feature flags), you can define customized traffic allocations for specific product features. Consequently, you can segment audiences based on various parameters. For instance, you can only roll out a new chatbot feature to beta customers. As a result, you can validate features before pushing them to production.

Optimizely Standout Features and Integrations

One standout feature is AI-generated insights that give you real-time guidance on optimizing content for improving conversions. Additionally, Optimizely also offers AI-powered recommendations for personalizing website and email copy.

Why I picked Crazy Egg: I’m amazed by the Shopify integration that Crazy Egg offers. Right off the bat, Crazy Egg features a “five visual snapshot” that provides heatmaps, scrollmaps and an interesting confetti report that depicts individual clicks on your website.

Crazy Egg provides a robust A/B testing solution. You can quickly tweak elements on your landing or checkout pages to track the corresponding impact on your sales. Additionally, the testing setup is quite simple: You only need to add the Crazy Egg snippet to any web page, and you’re ready.

Selection Criteria For A/B Testing Software

Here’s a summary of the main selection and evaluation criteria I used to develop my list of the best software:

Core Functionality

Here’s a list of essentials that every A/B testing software has to offer to clinch a spot on my shortlist:

  • Offers different types of testing, like A/B testing, multivariate testing and dynamic testing.
  • Ships a clean summary dashboard containing A/B test results and insights

Key A/B Testing Software Features

In addition to the core essentials above, here are some vital features that improve the effectiveness of an A/B testing tool. I assessed these factors while building my shortlist:

  • User Friction Analysis: Pinpointing uneasiness and friction in a customer journey allows you to tweak the correct digital elements.
  • Analytics: Collecting Key Performance Indicators (KPIs) from your A/B tests will help you analyze the effectiveness of various test variants.
  • Custom Goal Definition: By tying customer business objectives to A/B tests, you can clearly articulate how vital metrics improve upon testing.


A/B testing tools that ship an easy-to-use and straightforward UI fare high in my books. Additionally, easy-to-use A/B testing tools pave the way for seamless onboarding. Beginners must get acquainted with an A/B testing tool quickly to create and execute tests on the go. 

Software Integrations

I’ve mentioned the various integration possibilities that each tool offers. You can integrate A/B testing software with applications like collaboration tools, third-party analytics tools, CMS tools, and CRM tools.


Lastly, the A/B testing software shouldn’t burn a hole in your pocket. I’ve mentioned each tool’s pricing along with their free trial availability. All the tools feature a per-month SaaS subscription charge.

The typical monthly subscription charge varies between $10 up to $2000 per month. Some tools haven’t mentioned pricing so you would need to contact their sales teams for a customized quote.

A/B Testing Software FAQs

Find answers to common questions people ask about A/B testing software:

How do you perform an A/B test?

Here’s a six-step process you can follow for performing effective A/B tests:

  1. Define your goal: Determine your objectives for the A/B test.
  2. Identify testing scope: Decide which elements of your digital product you would like to test.
  3. Create variations: Develop multiple variants of your test elements. For instance, if you’re testing a CTA button, create variants with different combinations of colors, sizes, etc.
  4. Split traffic: Using A/B testing software, divide incoming traffic amongst your variants.
  5. Run Tests: Let the testing software run tests and collect data.
  6. Analyze results: Analyze your results to determine which variant performs better.

What are the types of A/B testing?

Here are some popular types of A/B testing:

  • A/B/n testing: This is just an extension of the traditional A/B tests. A/B/n testing involves multiple variants.
  • Multivariate testing: MVT involves testing combinations of multiple elements simultaneously. As a result, you can optimize complex pages with various elements to find the best combination.
  • Split URL testing: Here, users get directed to entirely different URLs, rather than variations.
  • Bandit testing: This involves dynamically allocating incoming traffic to the better-performing variant.

What are the benefits of A/B testing?

A/B testing promises several advantages, including data-driven decision-making and improved user experience. Consequently, you can realize increased conversions and reduced bounce rates.

What’s Next?

Selecting the right A/B testing software can go a long way in unraveling unique insights about improving your customer experience and conversion rates. I hope my guide helps you choose the right A/B testing software that propels your understanding of what elevates your customers’ digital experience.
