Only Bixlow, Mida and Wingify have Spanish websites; for a free plan with tests, Mida; for an AI that proposes and builds tests in Spanish without a developer, Bixlow; for large companies with server-side testing, Optimizely, Kameleoon or Wingify. - Source: https://bixlow.com/en/compare/best-ab-testing-tools - Language: en - Updated: 2026-11-02 - Publisher: Bixlow > **Before you read.** This list is published by Bixlow, which is one of the tools. To keep it useful anyway, every fact comes from each vendor's website (linked at the end, checked on 2 November 2026), and for each one we say who it suits best, including when that is not us. ## Quick comparison Prices exclude tax, in the currency each vendor publishes. | | Spanish website | Free plan with tests | Entry price | AI to build variants | Who it is for | | --- | --- | --- | --- | --- | --- | | Bixlow | Yes (and the app) | No (free plan analyses and proposes) | €24.17/month, yearly | Yes: proposes, builds and measures | SMBs, online stores, agencies | | Wingify (VWO + AB Tasty) | Yes | No, 30-day trial | Custom pricing | Yes (Wingz AI) | Mid-market and enterprise | | Mida | Yes | Yes, up to 3 live tests | $224/month, yearly | Yes (MidaGX) | SMBs and marketing | | Kameleoon | No | No, 30-day trial | $495/month | Yes (PBX) | Large companies | | Optimizely | No | No | Custom pricing | Yes, AI agents | Large companies | | Convert | No | No, free trial | $299/month, yearly | Yes, in beta | Mid-market and agencies | | Varify.io | No | No, 15-day trial | €199/month, yearly | Yes, on the Pro plan | SMBs and agencies | ## How to choose in two minutes Ask yourself three questions. First: do you have someone to build the variants? If not, rule out the tools that need a developer for anything beyond the basics. Second: do you need to test on the server or only on the website? If it is only the website, do not pay for a product platform. Third: how much traffic do you have? With few conversions a month any tool will take a while to give you a result, so check the sample size calculator first. ## Bixlow An AI CRO agent: it analyses your site, proposes hypotheses ranked by impact, builds the variants on your real site and tells you when there is a winner, using Bayesian statistics. The website, app and support are in Spanish. Best for: marketing and ecommerce teams with no developer for CRO. Worst for: anyone who needs feature flags, server-side tests or ready-made integrations with other tools. ## Wingify (VWO + AB Tasty) In September 2026 VWO and AB Tasty merged under the Wingify brand. It is a full suite: experimentation, personalization, behavioural analytics, feature flags and enterprise security certifications. It has a Spanish website. It does not publish prices and charges by monthly active users. Best for: mid-sized and large companies that want everything from one vendor. Worst for: a small store that only wants to run a few tests. ## Mida A light tool with a Spanish website, a visual editor and a generative AI (MidaGX) that creates variants from a description. Its free plan includes up to 3 live tests. Best for: teams that already know what to test and want something simple and cheap. Worst for: anyone who wants a detailed explanation of the statistical method, which its website does not describe. ## Kameleoon A French platform for large companies, with prompt-based experimentation (PBX), feature flags, server-side tests and demanding compliance options. Its website is in English, French and German. Best for: large companies with a product team and strict security requirements. Worst for: small businesses working in Spanish or on a tight budget. ## Optimizely One of the classic names in experimentation, now part of a broader digital experience platform (CMS, commerce). It offers AI agents to come up with and build experiments, and its own statistics engine. It does not publish prices. Best for: large companies already in its ecosystem. Worst for: anyone looking for a tool in Spanish or a price they can look up. ## Convert Very complete on the technical side: server-side tests, feature flags, over a hundred integrations, frequentist and Bayesian statistics and EU servers. In English. Best for: agencies and teams with a developer who want full control at a public price. Worst for: teams without a technical profile. ## Varify.io A German tool with a flat rate and no traffic limit, with data hosted in Germany. The Pro plan adds prompt-based experiments and Bayesian statistics. Its website is not in Spanish. Best for: high-traffic sites that do not want to pay per visitor. Worst for: anyone who wants the tool in Spanish. > **What about Google Optimize?.** Google shut Optimize down on 30 September 2023. It is no longer an option, even though many older lists still recommend it. ## FAQ ### What is the best A/B testing tool in Spanish? It depends on your team.
