VWO vs ABTestly. An honest comparison.
VWO details checked on vwo.com/pricing in August 2026. VWO's public page does not list a 100,000 tracked user price; that figure comes from its in app checkout. Check their site for current information.
Yes, we are ABTestly, so read this knowing who wrote it. Every claim is checkable, and where VWO does not publish a figure we say so rather than guess. There is a real section below on where VWO beats us, because it does, in several places.
Head to head
| VWO | ABTestly | |
|---|---|---|
| Pricing | Public page lists tiers, not a 100,000 MTU price. Ask VWO for a quote at that volume | Published: Free $0, Starter $99 / mo, Pro $249 / mo ($199 annual) for 100,000 MTU, unlimited experiments, Business $549 / mo, Enterprise custom pricing. 20% off annual |

| Test types | A/B, split URL, multivariate, multi arm, personalization | A/B testing with multiple variants and split URL tests. No multivariate, full stack or feature flag experimentation |

| Feature experimentation | Yes on higher tiers | Not offered |

| Integrations | Wide catalog | Writes an exposure event with the experiment and variant to your data layer; your GA4 or GTM setup forwards it |

VWO's public pricing page does not list a price for 100,000 tracked users, so ask VWO for a quote at that volume rather than trusting a number from us. Its public entry tier covers far fewer tracked users. All pricing exclusive of tax.
Where each one wins
Where VWO genuinely wins
- Breadth of CRO. Session recordings, surveys, funnels, and personalization all under one login. ABTestly offers heatmaps through Signals, but if your program relies on recordings, surveys, or funnels, VWO does more.
- Visual editor for marketers. A page owner can build and QA a variant without a developer.
- Feature experimentation. Server side flags and rollouts on higher tiers.
- Integrations and enterprise features. A wide catalog of one tag integrations, SSO, phone support, and formal compliance certifications.
- Vendor maturity. Established company with a large customer base and agency ecosystem.
Where ABTestly is better
- Pricing you can read. Four tiers on one page, no quote required. Pro is $249 / mo, or $199 / mo annual, for 100,000 MTU. VWO does not publish a 100,000 MTU price on its public page, so compare your own VWO quote against it.
- Code first workflow. Variants are authored as explicit JavaScript and CSS in Monaco, with linting and change history, making the code straightforward to review and copy into your own version control.
- Edge delivery. Config served from Cloudflare's edge in 300 cities.
- Snippet size stated up front. ~27 KB gzipped, loader under 1.5 KB. Published on the pricing page.
- Three statistics engines available. Frequentist on every plan. Sequential and Bayesian on Pro. No add on to unlock either one.
- No automatic overage charges. Going over your MTU never generates a surprise bill.
- Permanent free plan plus a 30 day money back guarantee on your first paid month.
Which should you pick?
Pick VWO if your CRO program spans qualitative and quantitative work, if marketers own the tests, if you need multivariate, feature flags, or personalization, or if you already run other VWO products (session recordings, surveys).
Pick ABTestly if your experiments are built by people who write code, your stack reports into GA4, and you want a published price at $249 / mo, or $199 / mo billed annually, for 100,000 tracked users. See our pricing.
Genuinely unsure? Start on the ABTestly free plan and see whether a code first workflow feels right. The VWO alternative page covers the shorter argument if you are earlier in the search.
Quick answers
How do VWO and ABTestly pricing compare?
ABTestly publishes its full pricing: Free $0, Starter $99 / mo, Pro $249 / mo, or $199 / mo billed annually, for 100,000 monthly tracked users with unlimited experiments, Business $549 / mo, and Enterprise custom pricing, with 20% off on annual billing. VWO does not publish a 100,000 tracked user price on its public pricing page, so ask VWO for a quote at that volume and compare it against ABTestly's published plan.
What does VWO have that ABTestly does not?
A full all in one CRO suite beyond A/B testing: session recordings, surveys, funnels, personalization, and feature experimentation, plus a visual editor and a large feature surface with wide integration catalog. ABTestly offers heatmaps through its Signals add on, but recordings, surveys, and personalization are not offered.
What does ABTestly have that VWO does not?
Pricing published in the open instead of quote gated, a permanent free plan, no automatic overage charges, three statistics engines (Frequentist on every plan; Sequential and Bayesian on Pro), a code first workflow, edge delivery from 300 cities with a snippet around 27 KB gzipped, and a 30 day money back guarantee on your first paid month.
Can I validate ABTestly against VWO before switching?
Yes. Validate the tracking first: install ABTestly on the free plan as a tracking only setup, or use mutually exclusive audiences so no visitor is ever in both tools, and confirm eligibility, consent, exposure, and goals. Then launch one real low risk test. Do not run the same live test in both tools at once.
