Best for: Teams running A/B testing & conversion optimization programs
Last updated: September 05, 2026
VWO is one of the most complete conversion optimization platforms going — A/B, split, multivariate, multi-page and multi-device testing, plus a research layer of heatmaps, session recordings, surveys and form analytics and optional server-side testing and personalisation, now with a visual editor that finally handles single-page apps. For a team running a real experimentation program, it's genuinely powerful. The honest catches: the free plan is being discontinued in 2026 (now a 30-day trial only), pricing is MTU-based and climbs fast with traffic, the best research and personalisation features are separate paid modules, and it's expensive overkill if you only need basic A/B testing.
STARTS AT
From ~$299/mo
VWO prices by monthly tracked users (MTUs), tiered plus custom. As a guide: Starter ~$314/mo annual (up to 10,000 MTUs, Testing only); Growth from ~$299/mo (up to 50,000 MTUs), rising with volume — e.g. ~$665/mo annual at 100,000 MTUs. Pro and Enterprise are custom-quoted by MTU volume, modules and contract. Since both traffic and add-on modules drive the bill, your real cost depends far more on usage and scope than the entry price.
Not for long. VWO historically offered a free Starter plan (up to 50,000 MTUs), but as of 2026 that free tier is being discontinued. Existing free users were notified, and new sign-ups now get a 30-day free trial rather than a permanent free plan. If you relied on the free tier, this is the biggest change to plan around — you'll need a paid plan to keep testing at scale. Use the trial to validate fit and size your MTUs before it converts.
VWO is modular. Testing is the core experimentation product. Insights adds the research layer — heatmaps, session recordings, surveys and form analytics. Full Stack extends to server-side testing and feature-flag rollouts for product/engineering. Personalize powers advanced rule-based personalisation. Each is a separate paid add-on, so a full research-plus-testing-plus-personalisation setup costs considerably more than testing alone — only pay for the modules your team will actively use.
Depends how much of the suite you'll use. VWO's edge is breadth: testing, research and personalisation under one roof with a mature, SPA-capable editor and strong reporting — valuable for teams running a real optimisation program. The honest counterpoint reviewers make: if you only need straightforward A/B testing, cheaper purpose-built tools deliver equivalent core functionality at a fraction of the cost. VWO is worth it when you actively use the research suite and test continuously; for the occasional page split-test, a lighter tool wins on value.
MTU = monthly tracked users, roughly the unique visitors VWO tracks for your experiments each month — the meter your plan is priced against. The implication: your cost scales with traffic. A high-traffic site can jump several hundred dollars a month between MTU bands, and exceeding your tier bumps you to the next. Before committing, estimate the MTUs you actually need in tests, decide if you can scope experiments to key pages or segments to control the number, and model cost at your real traffic — not the entry band.
Mid-sized and larger businesses running a genuine, ongoing CRO program — marketing, product and growth teams combining A/B testing with research (heatmaps, recordings, surveys) and maybe server-side testing or personalisation. For them the consolidated suite and mature tooling justify the price. Weaker fit for very small sites or teams needing only occasional basic A/B tests, where the loss of the free plan, MTU pricing and paid modules make lighter, cheaper tools better value — and for anyone who can't commit to using the modules they're paying for.
