Top 14 Best AB Testing Tools for Driving Growth in 2023 cover

Product analytics are crucial for understanding user behavior, conducting conversion optimization, and improving the customer experience. A/B testing tools take that to the next level by letting you test two versions of a product flow, web page, or landing page, then see how the different versions perform.

In this guide, we’ll go over the must-have features any A/B testing tool should have and walk you through 14 tools that can improve test performance in any use case!

TL;DR

  • A/B testing tools should have a visual editor, segmentation capabilities, analytics dashboards, and support multiple test types.
  • A/B testing tools can be used for SaaS products, web pages, and mobile apps.
  • There are plenty of free A/B testing tools to choose from (or paid tools with free versions).
  • Best A/B testing tools for SaaS companies: Userpilot, Amplitude, Statsig, and AB Tasty.
  • Best A/B testing tools for webpages: VWO, Zoho PageSense, Optimizely, CrazyEgg, and Kameleoon.

Must-have features of A/B testing tools

While the feature set of testing tools will vary depending on your use case, there are a few features that are simply a must-have:

  • Experiment creation/management. Testing tools should have a visual editor that makes it easy to create tests, create multiple variations, and quickly edit the design.
  • Segmentation capabilities. Testing tools should have advanced user segmentation capabilities that help you target specific groups and analyze test results by segment.
  • A/B testing types. Testing tools should support different types of A/B testing, such as split-testing, controlled tests, and multivariate testing.
  • Analytics features. Any good testing tool should have native features for tracking conversions or measuring progress toward a specific goal. The testing tool should also have a unified analytics dashboard that displays all A/B testing metrics in one place.

If your experimentation platform has the above features, it’ll be much easier to run tests and gather statistically significant results.

Best A/B testing tools for SaaS

Let’s start things off by looking at four A/B testing tools that can be used on SaaS products. Userpilot, Amplitude, Statsig, and AB Tasty all have built-in A/B testing features that can be used as a product experimentation platform.

Best A/B testing tools for mobile apps

With mobile devices accounting for more than half of global traffic, it should come as no surprise that developers are now looking for A/B testing tools that work on mobile apps too. Let’s take a look at three popular A/B testing tools that can be used for mobile testing!

Omniconvert

Omniconvert is a marketing optimization tool that helps non-technical users with A/B testing and post-test analysis. It helps customers design complex tests and review analytics with its user-friendly interface. It can also run experiments on different versions of the same website (e.g. mobile versus desktop).

Omniconvert A/B testing tool
Source: Omniconvert.

Key features

Omniconvert’s split-URL testing lets you create variants with different elements and test that against the current landing page to see how visitor behavior changes. The advanced targeting settings let you enter the URL of the new landing page variant then automatically redirect targeted visitors or users.

You can also adjust the traffic allocation slider to set the percentage (from 0% to 100%) of visitors that you’d like to include in the experiment. You can even set specific goals like sales, engagement, or bounce rate and edit the goal timeout settings to accurately measure results.

Omniconvert also lets you analyze user behavior in other areas of your app beyond landing pages. This could include conversion optimization for dynamic shopping carts or other areas in need of A/B testing. All experiments let you target a specific segment and page.

If you want to run the experiment on multiple pages, then just use the “URL starts with” or “page contains keyword” rules. These let you set the conditions for which pages the experiment should appear on.

Pricing

Omniconvert has two paid plans that start at $273/month when billed annually. However, pricing scales with the number of monthly pageviews, so larger companies with millions of website visitors could end up paying over $10,000/month for their subscription.

Omniconvert pricing

Here’s an overview of Omniconvert’s pricing tiers:

  • Platform. Starts at $273/month billed annually (or $390/month if you pay monthly) and includes A/B/n tests, surveys, multi-device testing, and more.
  • Enterprise. Priced on a quote basis and includes a dedicated account manager, data auditing, testing roadmaps, real-time reporting, and more.

Best for: Mobile split-testing and behavioral tracking.

Adobe Target

Adobe Target is an AI-powered testing tool that offers A/B testing and multivariate testing on an omnichannel scale. Its artificial intelligence and machine learning algorithms let you personalize multivariate tests with a single click to eliminate the technical barrier to A/B testing.

Adobe Target A/B testing tool
Source: Adobe Target.

Key features

Adobe Target generates cross-channel profiles for each user to ensure that A/B testing, server-side testing, and multivariate testing are all consistent regardless of the testing platform (mobile or desktop) the user is on.

This ensures that statistical analysis won’t be skewed when A/B testing changes on users across both platforms. Cross-channel profiles can also help you spot patterns in user behavior that, despite their statistical significance, may have slipped through the cracks of other testing tools.

Adobe Target also has rules-based and AI-powered personalization that helps you tailor tests to different users or segments. Manually set up personalization using the operating system, screen size, orientation, geolocation, touchscreen capabilities, or behavior patterns of your mobile users.

Alternatively, use the machine learning algorithms powered by Adobe Sensei to automatically personalize mobile experiences. Either way, you’ll be able to collect quantitative and qualitative data from all your users, no matter which device they’re currently using.

Pricing

Adobe prices the Adobe Target solution on a quote-based model, which means there are no publicly listed prices or plans on its website. You’ll need to enter your country, department, and primary use case in the request form to get a custom pricing quote for Adobe Target.

Best for: Cross-channel experimentation.

Apptimize

Apptimize is an A/B testing and release management platform aimed at businesses of all sizes. Unfortunately, its free version and entry-level paid plan only provide access to feature flagging. You’ll need to upgrade to the Enterprise plan to use Apptimize’s A/B experimentation capabilities.

Apptimize A/B testing tool
Source: Apptimize.

Key features

Apptimize isn’t the most user-friendly option since some features can only be used through the coding editor — but you also have the option of running no-code visual experiments mobile apps on Android and iOS.

The coding-based testing platform lets you add code blocks that implement changes to your app. However, Apptimize’s code blocks only work if you create a named section of code for every variant and/or experiment.

Visual experiments, on the other hand, let you make real-time changes to the mobile app without writing code. For instance, you could edit the text, images, or colors in your mobile app’s interface or toggle between release versions without needing to redeploy.

Dynamic variable experiments let you change any app variable (that you’ve previously tagged) through the Apptimize dashboard. This makes it possible to experiment with variables (such as images, layout, or other settings) across multiple release versions.

Pricing

Apptimize offers one free plan and two paid plans. Both of its paid plans operate on a quote-based pricing model with no prices listed on the website. Users who sign up for the free version will get a 30-day full-feature trial so they can test the capabilities of the Advanced and Enterprise plans.

Apptimize pricing

Here’s an Overview of Apptimize’s pricing tiers:

  • Standard. Free version that includes release management capabilities, up to five feature flags active at a time, data exporting, and onboarding support.
  • Advanced. Uses custom pricing and includes unlimited feature flags, segmentation/targeting, admin controls, and automatic event importing.
  • Enterprise. The only plan with A/B testing tools. Also includes experimentation, instant updates, and a unified results dashboard.

Best for: No-code Android and iOS experiments.

Best free AB testing tools

With Google Optimize being discontinued, many product teams are looking for free tools that can conduct both client and server-side testing. Fortunately, there are a couple of solid Google Optimize alternatives to consider!

Mojito

Mojito is an open-source split-testing stack optimized for both speed and security.

Mojito A/B testing tool
Source: Mojito.

Key features

Mojito isn’t a no-code solution, so you’ll need basic knowledge of JavaScript or YAML to run experiments. Mojito also lacks a WYSIWYG editor, which could lead to some frustration when creating test variants. Still, it does offer full data ownership (which you rarely find in a modern tech stack).

To use Mojito, you’ll need to set up three different components: Mojito JS Delivery, Mojito Snowplow Storage, and Mojito R Analytics. JS Delivery makes sure users see the right experiments, Snowplow Storage handles data collection/modeling, and R Analytics takes care of metric reporting.

While Mojito doesn’t have a built-in analytics dashboard, it does let you build custom HTML reports from the metrics in your data warehouse. Because Mojito is served from your domain and uses up fewer resources than a SaaS tool, it can actually speed up page load times too.

Pricing

Mojito is free to use and lets you self-host experiments, unlike other server-side testing tools.

Best for: Self-hosted experiments and page load speeds.

Unleash

Unleash is an open-source feature flagging solution aimed at developers, small teams, and enterprise organizations.

Unleash A/B testing tool
Source: Unleash.

Key features

Unleash is a pretty powerful tool for developers despite being free and self-hosted. Other tools are more expensive because Unleash only charges you for its cloud-hosted plans but offers the self-hosted version for free.

Unleash’s feature toggles are the main mechanism for A/B testing. Experiment toggles let you run experiments and collect data to measure their impact. Sadly, tracking impression data will require some coding knowledge and API usage.

A/B tests also won’t be as robust as the multivariate tests Google Optimize users have grown accustomed to. If you do manage to get tests and impression tracking set up, you’ll be able to stream results data to a third-party analytics provider like Google Analytics.

Pricing

Unleash has a free version and two paid plans. All Unleash plans accommodate unlimited monthly active users (MAUs) and offer unlimited feature flagging. The free version is self-hosted, the Pro plan is cloud-hosted, and the Enterprise tier lets you choose between the two deployment options.

Unleash pricing
Source: Unleash.

Here’s an overview of Unleash’s pricing tiers:

  • Open Source. Free version for developers who self-host all their experiments (since cloud-hosting is only provided on Unleash’s paid subscriptions).
  • Pro. Starts at $80/month for five team members. The plan can be expanded to accommodate up to 20 seats but this cost an extra $15/month for each seat.
  • Enterprise. Priced on a quote basis and offers both cloud-hosted and self-hosted options. Also includes custom roles and private instance deployment.

Best for: Developers.

Conclusion

As you can see, A/B testing helps you make data-driven decisions and optimize the customer experience by iterating on different variations. If you’re ready to start A/B testing and acting on test results, then it’s time to get your free Userpilot demo today!
