Best A/B Testing Software: 10 Experimentation Tools Compared by Price, Fit and Company Size

A/B testing software splits your visitors between a control and one or more variants, measures a goal such as sign-ups or purchases, and tells you whether the difference is real or random noise. Teams use it to settle design and messaging debates with data. This guide ranks ten tools from the AB Testing Software category by listed starting price and explains how to match one to your traffic and budget.

Traffic is the first constraint. Low-traffic sites cannot detect small lifts, so they need bigger changes or a cheaper tool for qualitative research. If you want a head-to-head on three of the big names, read our Optimizely vs VWO vs AB Tasty comparison. Experiments that set cookies need a lawful basis under the GDPR, and variants must stay usable for everyone, as the W3C WCAG 2.2 guidelines describe. For a hands-on look at one platform, see VWO.

How We Ranked These A/B Testing Tools

We listed every product in the SaaSPodium AB Testing Software category and sorted by listed starting price, lowest first. We used listing data only: tagline, brand, price, target company size and deployment. Ratings are not published for these tools yet, so none are shown or implied.

Price order is a shortlist aid, not a quality ranking. The cheapest tool is not the best choice if it lacks the targeting, statistics engine or integrations your program needs, so verify those on each vendor's site.

How to Size an A/B Test Before You Buy

Estimate the sample size per variant before choosing a plan, because traffic limits drive cost. A common rule of thumb for roughly 80% power at a 5% significance level is sixteen times the variance divided by the square of the lift you want to detect.

Here n is visitors per variant, p is your baseline conversion rate and δ is the absolute change you want to detect. With a 5% baseline and a one-point absolute lift (δ = 0.01), n is about 16 × 0.05 × 0.95 ÷ 0.0001, or roughly 7,600 visitors per variant. Use a proper calculator before launching, but this estimate shows why small sites struggle.

Lift calculation

Report lift together with a confidence interval, and avoid stopping a test early because a variant looks ahead.

Which Tool Fits Which Team

Match the tool to your program: low-cost behavior analysis for small sites, landing page testing for campaign teams, and full experimentation with personalization for enterprise programs with high traffic and several stakeholders.

• Small sites and stores: shortlist Crazy Egg, Omniconvert and Unbounce.
• Agencies and practitioners: review Convert Experiences and VWO.
• Enterprise programs: compare Optimizely, SiteSpect, Kameleoon and Adobe Target.

Frequently Asked Questions

How much does A/B testing software cost?
Listed starting prices in the SaaSPodium directory run from $29 for Crazy Egg to $10,000 for Adobe Target as of October 2026. Traffic limits and modules change the real cost, so request a quote based on your monthly visitors.

Which A/B testing tool is best for a small business?
Small businesses should start with Crazy Egg, Omniconvert or Unbounce, which are listed for small teams and start at $273 or less. Choose based on whether your tests happen on landing pages, product pages or across the full site, and check traffic caps before subscribing.

How long should an A/B test run?
Run it until you reach the planned sample size and at least one full business cycle, usually one to two weeks, so weekday and weekend behavior are both covered. Stopping early because a variant looks ahead inflates false positives.
