AB Tasty vs Kameleoon vs Wingify: the 2026 comparison after the merger

Updated on October 9, 2026

Type abtasty.com into your browser: you land on wingify.com. On September 16, 2026, AB Tasty and VWO officially merged under a single brand, Wingify, with over 4,000 customers and more than $100 million in combined revenue. If you were comparing "AB Tasty vs. Kameleoon" for your next contract, the question has changed: you're no longer choosing between two French vendors of comparable size, but between an international group controlled by an investment fund and a Parisian vendor that has remained independent with around 200 employees.

AB Tasty vs Kameleoon in 2026: the short answer

In 2026, comparing AB Tasty and Kameleoon is like comparing Wingify, a complete experience optimization suite (testing, personalization, behavioral analytics, feature flags, product search) sold on a quote basis, and Kameleoon, an AI-driven experimentation platform with a starting public price of $495 per month for 50,000 tracked users. The first is suitable for large accounts that want a single supplier for the entire customer journey; the second, for teams that want to test quickly with a budget known in advance.

Three nuances. The Wingify suite remains, for now, two coexisting technical products. Kameleoon's entry-level price only grants access to a limited scope. And in both cases, it's your traffic volume, more than the list of features, that determines what you can actually test. If concepts like MTU, significance, or statistical power are unfamiliar to you, our glossary of A/B testing defines them simply.

What the AB Tasty + VWO merger really changed

The merger has changed the brand, the shareholder and the roadmap, but not yet your contracts or your ongoing campaigns. Here is the verified timeline.

• January 20, 2026 The Everstone fund, already the majority shareholder of Wingify (the vendor of VWO) since early 2025, announces the merger with AB Tasty. According to the TechCrunch article dedicated to the operationThe group as a whole generates over $100 million in annual revenue, employs approximately 800 people across 11 offices, and serves over 4,000 clients (3,000 for VWO and 1,000 for AB Tasty). Its headquarters are in New Delhi.
• June 13, 2026 VWO users are switching to app.wingify.com. The VWO brand is being phased out in favor of Wingify.
• September 16, 2026 The unified brand, the wingify.com website, and the platform presented as "agentic" have officially launched. The abtasty.com domain now redirects to wingify.com (redirection observed on October 6, 2026).

The four founders share the leadership: Sparsh Gupta (CEO) and Ankit Jain on the VWO side, Rémi Aubert and Alix de Sagazan on the AB Tasty side.

For customers, the official Wingify page on the transition states that there are no immediate changes to the contract, pricing, or support; that history, reports, and integrations are preserved; and that ongoing campaigns continue to run. The two technical platforms still operate independently, with integration announced as gradual. Note that support emails now come from a @wingify.com domain, and passkeys must be recreated (SSO/SAML continues to function).

This merger is part of a wave of consolidation: OpenAI acquired Statsig and Datadog acquired Eppo in 2025. Several competing vendors (Convert, Varify, Mida) also report that VWO discontinued its free offering in early 2026. We were unable to verify this on an official website; consider it information to be confirmed with your sales representative.

Kameleoon in 2026: independent and focused on conversational AI

Kameleoon is today the leading French vendor of A/B testing that has remained independent of consolidation: founded in 2012, based in Paris, with approximately 200 employees and more than 1,000 client brands. The company has offices in New York, Ontario, London and Offenburg, and claims ISO 27001 and SOC 2 certifications.

Its strategic shift is called PBX, for Prompt-Based Experimentation You describe the desired variation in natural language (for example, "three-column product grid on mobile with free shipping highlighted"), the AI ​​generates the modification, and you validate it before publishing. Launched in 2025, PBX was complemented in May 2026 by PBX Ideate, a module that analyzes a page and categorizes test ideas based on over 20,000 historical experiences. Kameleoon reports that, among its early adopters, PBX generated over 40% of the experiments within three months (vendor figures, to be interpreted as such).

Kameleoon initially sells an experimentation engine and offers the rest as modules (customization, feature management, mobile applications); Wingify sells a suite. See also our page BlastOptimize versus Kameleoon.

Wingify vs Kameleoon comparison chart

On paper, the two platforms cover the same types of tests; they differ mainly in the scope of the suite, pricing transparency, and the way in which AI is integrated. The table below summarizes the public information collected on October 6, 2026.

Comparisons dated 2025 miss this point: the AB Tasty/Kameleoon head-to-head comparison no longer makes sense product by product, since the two old catalogues are now sold together.

Prices: what is public and what is not

Kameleoon publishes an entry price ($495 per month for 50,000 users tracked per month and 10 experiments), Wingify does not publish one. This is the most tangible difference for an SME or a team that needs to get a budget approved.

Kameleoon: a clear initial level, then customization

The official Kameleoon price list distinguishes three tiers: a 30-day free trial limited to 3 experiences, the PBX Starter tier starting at $495 per month (50,000 MTUs, 10 experiences, sequential testing, over 40 segmentation criteria, unlimited metrics and audiences, Figma integration), and an Enterprise offering with a quote (unlimited experiences and traffic, code editor, personalization, feature management, SSO). On a per-visitor basis, the Starter tier costs approximately $9.90 per 1,000 tracked users.

Wingify: three plans, no price displayed

Wingify's pricing page presents three plans (Growth, Pro, Enterprise) per module, but specifies that the price is customized based on traffic volume, selected modules, and integration scope. Billing is based on monthly active users (MAU), or on tracked users (MTU) for behavioral analytics. The published limits are informative: in Growth, 1 workspace and 1 domain, 3 simultaneous personalization campaigns, 10 feature flags, and 1 month of behavioral data retention. Discounts are available for multi-year commitments and bundled offers.

To give you an idea of ​​the scale, Capterra France had a starting price of €15,000 for AB Tasty before the merger, compared to €495 for Kameleoon. Over twelve months, the Starter tier represents approximately $5,940: the difference with a customized suite can therefore reach a factor of 2 to 3 in the first year alone, even before any add-on modules. Our BlastOptimize pricing are available online to complete your comparison grid.

The real limit: your traffic, not the number of tests

With 50,000 visitors per month, the 10-experience cap of Kameleoon's Starter tier will almost never be your real limit: your traffic only allows you to complete about two reliable tests per month. This is the calculation that feature comparisons overlook.

Let's take a common example: a page that converts at 3%, and a variant you hope will increase that rate to 3.6% (a relative increase of 20%). To detect this difference with 95% confidence and 80% power, you need approximately 13,900 visitors per variant, or nearly 27,800 for a typical A/B test. With 50,000 monthly visitors spread across the entire site, you can, at best, run one or two such tests per month, and only if each test captures the majority of the traffic.

If you're aiming for a more modest gain, from 3% to 3.3% (+10%), the requirement jumps to around 53,200 visitors per variant: more than two months of total traffic for a single test. Adding variants worsens the situation, which explains why a multivariate test compared to an A/B test requires a much larger volume.

Two consequences for your choice of tool:

• Paying for "unlimited experiments" is only worthwhile if your traffic follows. If you have fewer than a few hundred thousand monthly visitors, compare the cost per successful test instead.
• Running multiple tests in parallel on low traffic increases the risk of concluding that the problem is noise. The article on false positives in A/B testing details this trap, and the list of common mistakes in A/B testing show the others.

AI: Wingz vs. PBX

Wingify and Kameleoon both rely on AI, but not in the same place: Wingz aims to be an analysis and recommendation layer across the entire suite, while PBX focuses on creating variants with a simple prompt.

According to Wingify, Wingz explains results in plain language, suggests hypotheses, controls campaign configuration, and can build a campaign from written instructions. Its value increases with the number of modules used. As for Kameleoon, the PBX Ideate launch announcement highlights a development time saving of up to 89% and 8,000 test ideas generated by 80 customers in the pilot phase.

These figures come from the vendors. AI accelerates the production of variants, not the collection of a sufficient sample. Before paying for an assistant, check that your goals and your conversion tracking are reliable: an AI that optimizes a poorly measured event optimizes noise. If your main need is to automate the decision (stop a loser, promote a winner), also consider what a logic of autopilot test automation.

Contractual risks after a merger: clauses to check

A merger does not change your current contract, but it changes the balance of power at renewal: this is where price increases, groupings of offers and forced migrations take place. Industry history shows that when Google shut down Optimize in 2023, thousands of teams had to migrate within months.

AB Tasty, VWO or prospective Kameleoon customers, please request in writing:

• The ceiling for increases upon renewal : a maximum percentage over 12 or 24 months, especially if your traffic increases (billing per MAU or MTU).
• The technical platform roadmap Wingify's two engines will converge. On what date will your script, visual editor, and integrations change?
• Data export : format, time frame and cost to retrieve test history and segments in case of departure.
• The location of the accommodation and the list of subcontractors : the change of shareholder may modify the subcontracting chain declared in your data processing agreement (GDPR).
• The level of support : written first response times in black and white, French-speaking interlocutor, and not just a simple oral promise.
• The change of control clause : Can it allow you to exit without penalty if the vendor is bought out again?

These points also apply to Kameleoon: today's independence guarantees nothing for tomorrow.

Which tool for which profile?

Choose Wingify if you want a single suite for a large account, Kameleoon if you want an experimentation engine with a known entry price, and a lighter solution if your traffic does not justify either.

Profile 1: Large multi-brand account

Several domains, a product team using feature flags, a need for personalization and behavioral analytics: Wingify Pro or Enterprise makes sense, provided you negotiate the clauses mentioned above. If you already use one of the two catalogs, leverage that as negotiating leverage.

Profile 2: Medium-sized e-commerce business

With between 50,000 and 500,000 visitors per month, a CRO team of one to three people, and few developers, Kameleoon's PBX meets resource constraints well, and the entry price is known. Check if customization, often essential in A/B testing for e-commercerequires upgrading to Enterprise.

Profile 3: SME, B2B website or limited traffic

Below 50,000 monthly visitors, the calculation in the previous section fully applies: you'll launch one successful test per month at best. A five-figure annual revenue stream is then difficult to make profitable. Opt for a simple tool, with a No-code visual editor and billing tailored to your volume. This is the segment BlastOptimize is targeting; our page comparison between BlastOptimize and AB Tasty details the differences in scope, which we invite you to verify by testing on your own site.

Profile 4: Performance-sensitive site

Media, paid landing pages: measure the size and latency of each script before signing. The ultra-fast variant delivery is a criterion to be verified, not taken at face value.

Checklist before signing or renewing

Eight checks are enough to avoid unpleasant surprises, regardless of the tool chosen.

1. Calculate your monthly testable traffic (targeted pages, not the entire site) and the number of successful tests it allows per month.
2. Request a written quote from the MAU or MTU, with the price at the next higher tier if your traffic increases by 30%.
3. Start the 30-day free trial of each tool on the same page, and measure the impact of the script on load time.
4. Check the proposed statistical method (frequentist, Bayesian, sequential) and its documentation.
5. Get the technical convergence roadmap if you are an AB Tasty or VWO customer.
6. Have the data hosting and the list of subcontractors validated by your DPO.
7. Test the export of your results and segments before signing, not when leaving.
8. Compare the quality of the results tables: a test analysis dashboard readability saves hours of reporting each month.

FAQ

Does AB Tasty still exist in 2026?

The AB Tasty brand was merged into Wingify on September 16, 2026, and abtasty.com redirects to wingify.com. The technical platform continues to operate for existing customers, with no immediate changes to contracts or prices according to the vendor, pending a gradual integration with the former VWO.

Do VWO and AB Tasty customers need to migrate their tests?

Not immediately. Ongoing campaigns, history, and integrations are preserved. VWO users have been logging in to app.wingify.com since June 13, 2026. Ask your sales representative for the convergence date of the two engines, as this will determine whether a script migration is required.

How much does Kameleoon cost?

The PBX Starter tier starts at $495 per month for 50,000 tracked users per month and up to 10 experiences. A 30-day free trial allows you to create 3 experiences. The Enterprise plan, which includes customization and feature management, is available upon request.

How much does Wingify cost?

Wingify does not publish any prices. Pricing is customized based on monthly active users, modules, and the plan (Growth, Pro, Enterprise). Before the merger, Capterra France indicated a starting price of €15,000 for AB Tasty, which provides a rough estimate, not a quote.

Is Kameleoon better suited to SMEs than AB Tasty?

Its public entry price makes it more accessible, but $495 per month remains a significant expense for a low-traffic site that will only be able to complete one or two tests per month. Compare the cost per successful test rather than the listed price.

Does the merger pose a problem of data sovereignty?

A change in shareholders does not automatically transfer your data, but it may alter the list of subcontractors. Request the hosting location and the updated data processing agreement, and have them validated by your Data Protection Officer (DPO).

Is it possible to switch A/B testing tools without losing your history?

Yes, provided that the results, segments, and hypothesis documentation are exported before the end of the contract. The tests themselves will need to be recreated in the new tool: plan for a few weeks of dual-running on the key pages.
