Teams reconsidering VWO tend to meet the same three things: a pricing page without figures, features that sit one tier higher than expected, and a corporate structure that changed when Wingify united with AB Tasty. The tools below range from flat-rate website testers to warehouse-native and flag-first platforms.
Sebastiaan SmitsFounderShort answer: Varify, Mida and Convert.com head the list of VWO (now part of Wingify) alternatives drawn from our A/B testing tool ranking. Our rule for order: vendors outside the big brands go first, and the largest names are not placed in the top three. Varify is the one to try if you want a visible monthly price that does not follow your traffic. All 11 alternatives below are ranked products from Best A/B Testing Tools in 2026, and each says where it differs from VWO (now part of Wingify).
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
Wingify's pricing page, where vwo.com now redirects, names Growth, Pro and Enterprise but shows only a Schedule a Demo button on every tier. There are no prices and no free plan on that page. Anyone comparing budgets has to book a call first, which is slow when the shortlist has ten names.
On the Web Experimentation table, Growth offers A/B, split URL and rollout tests only. Multivariate testing, sample ratio mismatch detection and guardrail metrics are marked as Pro features. A team that wants to check whether a test is statistically sound pays for the middle tier, whatever its traffic.
The pricing page marks SSO, API access and self-hosting as Enterprise only, across web testing, feature experimentation and personalization. Wingify's home page also says VWO and AB Tasty have come together, without saying which owns the other, and the VWO domain now forwards to wingify.com. A security review may land you in the largest quote, with a new corporate structure behind it.

Germany · Published
Varify is a German GmbH with EU servers and sells website tests on a flat monthly plan, so more visitors do not raise the bill. The first plan covers one domain and five concurrent experiments; Bayesian statistics, unlimited seats and API access sit on the plan above it. AI features are a separate credit package, and a 15-day trial is offered.

GrowthBook leaves event collection to you and reads results from your own data warehouse. The cloud Starter plan is free for three users and one project, with unlimited experiments, flags and traffic; Pro is $40 per seat a month. Approval workflows, SSO and SCIM are for Enterprise. The core code is MIT-licensed and can be self-hosted.

Netherlands · On request
ABsmartly is an Amsterdam company whose stats engine uses group sequential testing, so a test can end early once a result crosses a boundary. SDKs cover many server stacks. There is no price on the site, the contract is yearly, and the way in is a paid 30-day proof of value instead of a free trial.
Switch from VWO (now part of Wingify) if product teams run many server-side tests and want a Dutch vendor with sequential statistics.

France · Published
Kameleoon, a French company, publishes its PBX Starter at 495 dollars a month for ten experiments and 50,000 visitors. Feature experimentation, personalization and mobile testing come as an add-on bundle without a listed price. The 30-day trial permits three experiments, and Enterprise brings SSO, custom data residency and on-premise set-up. The legal notice names Hetzner in Germany.
Switch from VWO (now part of Wingify) if you want a European vendor with German hosting and an entry price you can read.
United Kingdom · Published
Flagsmith, from the United Kingdom, meters API requests instead of visitors: 50,000 a month free, one million on Start-Up at $40 a month billed yearly. A/B and multivariate tests start on Start-Up, while SAML, roles and audit logs begin on Scale-Up at $250. Most code is BSD-3-Clause and runs self-hosted. The free plan has one team member.
Switch from VWO (now part of Wingify) if tests are mostly server-side and you want to self-host the open-source core.
Flagsmith comes 12 of 16 when A/B testing tool products are ranked here →
United States · Published
PostHog attaches experiments to feature flags and puts them inside an analytics suite, with Bayesian or frequentist statistics and session replays linked to every variant. The code outside the ee directory is MIT-licensed, and billing is by usage after a monthly allowance. It reads more as a product tool than a page-editing tool for marketers.
Switch from VWO (now part of Wingify) if product analytics, replays and tests should live in one tool, run by developers.
United States · Published
Statsig's free Developer plan holds 2M events a month with unlimited flag checks; Pro is $150 a month with 5M events and $0.05 per extra thousand. SSO, roles and warehouse-native deployment require Enterprise. The site now says it belongs to the Amplitude family, and the terms come from Amplitude, Inc.
Switch from VWO (now part of Wingify) if your team is product-led, counts events anyway and can accept a US owner.

Optimizely publishes no prices at all, saying each plan is individually packaged. Experimentation spans web, multi-page, feature and server-side tests, with its own Stats Engine and warehouse-native analytics. EU customers contract with Optimizely AB in Stockholm, US customers with a New York company. It is a heavier purchase than VWO's Growth tier.
Switch from VWO (now part of Wingify) if a large organisation needs server-side and warehouse analytics under one enterprise contract.

LaunchDarkly started as release control and added experiments, with 100,000 experimentation users a month on its free developer plan. The paid plan bills per service connection and per thousand client-side users, which is hard to forecast for a busy website, and advanced targeting moves to Enterprise. It has 30 SDKs and suits engineering teams.
Switch from VWO (now part of Wingify) if developers already ship behind flags and tests should follow the same rollout path.

Varify: It sells website tests on a flat plan with no traffic cap, and the first plan includes five concurrent experiments on one domain.
Mida: The free sandbox allows 100,000 tracked users and three live tests, and Growth is listed from $224 a month billed annually.
GrowthBook: Results are read from your own warehouse, and the cloud free plan allows unlimited experiments, flags and traffic for three users.
Convert.com: Pro at $420 a month billed annually includes SSO, multivariate tests and feature flags, with a free VWO migration listed.
Kameleoon: It is French, its legal notice names Hetzner in Germany, and the Starter is published at 495 dollars a month.
VWO remains a sound choice when marketers need a visual editor and code editor, A/B, split URL and multivariate tests, personalization, heatmaps and recordings from one vendor. Wingify's security page lists ISO 27001, ISO 27701, PCI DSS and SOC 2 Type II, data can be hosted in the US, Belgium or India, and its home page mentions a 30-day free trial. If a Pro plan is in place and SSO is not required, moving means rebuilding tests and tracking for little gain.
List running and finished tests with their goals, audiences and results, and download reports before the contract ends. Winning variants worth keeping should be rebuilt as permanent site changes.
Remove the VWO tag only when the new tool's script is live, to avoid pages loading both and flicker. Convert's pricing page lists free migration from VWO, and other vendors may offer similar help, so ask.
Run a known A/A or an earlier winner in the new tool before trusting its numbers. Statistical engines differ, so compare significance rules, not only the headline uplift.
For a marketing team that mainly tests pages, Varify, Mida and Convert come first because their prices are on the page and they keep a visual editor. Developers with a warehouse will look at GrowthBook, and product teams at PostHog or Statsig.
Mida has a free sandbox of 100,000 monthly tracked users with three live tests. GrowthBook's cloud Starter is free for three users, Statsig's Developer plan includes 2M events a month, and Flagsmith has a free plan with 50,000 requests.
Convert, Mida, Flagsmith, GrowthBook Pro, Statsig Pro and Kameleoon's Starter all show numbers. VWO and Optimizely do not, and ABsmartly sells on a yearly contract with the price on request.
VWO lists self-hosting as an Enterprise feature. GrowthBook and Flagsmith publish their code and offer self-hosted options, and PostHog's core is MIT-licensed. Self-hosting shifts maintenance to your team.
Varify says its servers are in the EU and Convert stores data in Frankfurt. Kameleoon's legal notice names Hetzner in Germany, and VWO offers a Belgium region next to the US and India.
Convert lists a free VWO migration in the feature list of Growth, Pro and Enterprise. We did not find a similar line for the other tools we read.
