I judge each option using two questions before looking at the price. Does a test keep one destination URL, so an ad never has to be edited? Google's campaign editing guide explains what changes when you edit an ad. And does the page match what the ad promised, which Google scores as landing page experience?
I would shortlist the first three, then decide with a real test. Evan Miller's How Not To Run an A/B Test explains why you should fix the sample size before a test starts, and our split test sample size calculator works out how many visitors and how many days that requires.
1. ElasticFunnels
Affiliates who split-test paid traffic
Starts at USD 97/mo.
I would pick ElasticFunnels if you buy traffic and judge pages by conversion rate. It rotates split-test variants under one URL so your ad learning survives, and it keeps the page, checkout and attribution on one record. It is newer than the established platforms and independent review coverage is still thin, so run one test campaign before moving a whole business.

2. Unbounce
Pure landing pages, with checkout handled elsewhere
Starts at USD 29/mo.
Unbounce is the pick if you want a fast, mature page builder with AI traffic routing and you do not take payment on the page. Budget for the traffic caps, and note that classic A/B testing only starts on the Experiment plan, above the entry tier.

3. ClickFunnels
Running the whole funnel in one place
Starts at USD 97/mo.
Groove's own site lists ClickFunnels next to Kartra and GoHighLevel. See the GroovePages product page.

4. Systeme.io
Starting on a free plan
Starts with a free plan, or USD 17/mo.
A 2022 commenter left GroovePages for Systeme.io and called that builder easier. See the comment on r/bloggervoice.

5. Instapage
Ad-to-page personalization at scale
Starts at USD 99/mo.
Instapage is the pick if you run many ads and want each matched to its own page, with server-side testing and heatmaps. It is the most expensive option here, and server-side A/B testing only starts on the Optimize plan.

6. Landingi
AI pages on a small budget
Starts at USD 24/mo.
Landingi is the pick if you want an AI page generator and server-side testing without Instapage's price. Watch the credit system for AI use and the 2,000-visit cap on the entry plan.

7. Swipe Pages
Fast AMP pages for mobile paid traffic
Starts at USD 29/mo.
Swipe Pages is a good fit for paid traffic. More than 7,000 marketers use it, and its AMP pages load near-instantly on mobile. Same-URL A/B testing starts on the Marketer plan, conversions are unlimited on every plan, and its 14-day trial requires no credit card. AMP limits custom code, and there is no native heatmap or call tracking. Buy it if you want a fast, focused landing page with ad-safe testing and a checkout. Look elsewhere if you need a rich, interactive page or a full affiliate-tracking stack in one tool.

8. Leadpages
Uncapped traffic with server-side testing
Starts at USD 99/mo.
Leadpages is worth it if you send paid traffic to lead-gen pages and want split tests without a visitor cap. Grow, its first testing plan, runs server-side A/B tests and dynamic text replacement, and no plan meters traffic. Skip it if you only publish pages or sell your own offer with upsells: the publishing plans cannot test, and its ecommerce is basic. Heatmaps and Smart Traffic are on the Optimize plan, and the 7-day trial requires a card.

9. Checkout Champ
High-volume checkout and upsell funnels
Starts at USD 300/mo + 1%.
Checkout Champ is the pick for an established seller doing real order volume who needs a customizable checkout, one-click upsells and multi-gateway routing on one platform. It processes billions a year and targets direct-response ecommerce. It costs far more than a page builder and also takes 1% of sales, onboarding is demo-led with no self-serve trial, and split testing runs page-level A/B/C/D without same-URL rotation. It is overkill for a beginner or a low-volume store.

10. GoHighLevel
Agencies that need a CRM behind the funnel
Starts at USD 97/mo.
GoHighLevel is an established agency platform that has facilitated billions in sales and carries strong aggregate ratings. Its page builder and split testing are weaker than its CRM, follow-up automation and client sub-accounts, while billing surprises and slow support recur in user complaints. Buy it for an agency or lead-generation business that needs those systems behind the funnel. Skip it if you only need a landing page and a same-URL A/B test for paid traffic.

11. Kajabi
Established coaches and course creators selling their own offers
Starts at USD 143/mo.
Kajabi is real. It is the established, default platform for coaches and course creators, with more than 100,000 businesses on it and no cut taken from your sales. You would regret it as an affiliate buying paid traffic: the product is built to host and sell your own courses, memberships and coaching, and fast landers or the ad-safe split tests that protect a Meta or Google campaign sit outside its focus. It is also expensive, from $143/mo on the annual plan. Buy it if you sell your own courses or coaching and want a website, email, checkout and course delivery in one system. Skip it if you just need a lander and a same-URL A/B test.

12. Kartra
Selling your own offer with email built in
Starts at USD 52/mo.
Kartra has been around since 2018, and the vendor reports more than 60,000 businesses use its pages, email, checkout, courses and affiliate program. It is built for selling your own courses and coaching, while its split testing runs page by page without same-URL rotation. Support also draws steady complaints, making it a poor fit for an affiliate buying cold traffic. Buy it if you sell your own offer and want one system instead of a stack, starting at $52 a month on the annual plan. Skip it if you only need a fast landing page and an ad-safe A/B test.

13. CartFlows
Self-hosted WooCommerce stores selling their own offer
Starts with a free plan, or USD 99/yr.
CartFlows is widely installed and much cheaper than a hosted funnel builder, but it only makes sense if you run your own WordPress and WooCommerce store. It adds a checkout, order bumps and one-click upsells to WooCommerce, and there is a free version to try. Buy it if you sell your own products on WordPress and want funnels without a monthly SaaS bill. Skip it if you send paid clicks to a hosted landing page and never touch WordPress, or if you need same-URL server-side split testing. Support and billing draw recurring complaints, and introductory prices increase upon renewal.

14. FunnelKit
WooCommerce stores that want checkout, upsells and email automation in one plugin
Starts with a free plan, or USD 99.50/yr.
FunnelKit is a widely installed WordPress funnel plugin that bundles email, SMS and a CRM alongside the checkout, so a WooCommerce store selling its own products gets upsells and follow-up in one place. Buy it if you want a checkout that converts, plus automation, without a monthly subscription. Skip it if you send paid clicks to a hosted landing page and never touch WordPress, or if you need same-URL server-side split testing, because its A/B testing runs at the funnel-step level. Support and billing draw recurring complaints, and introductory prices increase upon renewal.

15. Builderall
Many tools on one low monthly price
Starts at €7.50/mo.
Builderall has been around for years, and the vendor reports more than two million users across its website builder, funnels, email, checkout, courses and webinars. It is a poor fit for an affiliate buying cold traffic because it lacks same-URL split testing and affiliate-network postbacks, and it draws repeated complaints about outages and slow support. Buy it if you want a wide set of tools on one low-cost bill and can accept rough edges. Skip it if you need a fast landing page and an ad-safe A/B test.

16. Elementor
WordPress sites that need a visual lander and can test elsewhere
Starts with a free plan, or USD 60/yr.
Elementor is enough for a WordPress lander when you already host the site, you want the page in a visual editor, and you can live without a built-in split test. Step up from the entry Pro plan if the page needs popups or WooCommerce blocks. Keep CartFlows or FunnelKit for the checkout. Move to Leadpages or Swipe Pages when the ad URL has to stay fixed while you test.
