An AB Tasty alternative with published pricing

AB Tasty pricing after the Wingify move

AB Tasty no longer publishes its own pricing page. Its pricing URL lands on Wingify's, which offers no fixed plans: each customer gets a custom proposal, priced on monthly active users for most products. The same page offers a 30-day trial with no credit card, though it doesn't say whether that trial covers the legacy AB Tasty product or only the VWO-derived Wingify app.

Vendr reports a median AB Tasty contract of $66,500 a year (range shown $37,191 to $70,785), and its guidance puts sites with 50,000 to 250,000 monthly sessions at $15,000 to $45,000 a year and full-platform enterprise deals at $80,000 to $150,000 or more (page last updated February 2026). Those are third-party estimates, not AB Tasty prices.

Otter publishes everything: $39/mo (one project), $79/mo (five), $149/mo (unlimited projects), all features on all plans, unlimited visitors, and a 14-day self-serve trial with no card. If A/B testing is the job, you shouldn't need a procurement cycle to start. See our pricing page.

Statistics: two engines vs one

AB Tasty reports results with a Bayesian engine, a 'gain probability' with credible intervals, and uses a Mann-Whitney U test for continuous metrics like average order value. That's a sound, well-documented setup.

Otter's manual-split experiments can use Bayesian chance-to-beat reporting or frequentist analysis using a two-proportion z-test (Fisher's exact test for small samples) at 80/90/95/99% confidence, with Bonferroni-adjusted thresholds for multiple challengers. Multi-armed bandit experiments use Bayesian reporting automatically. Revenue goals get their own statistical treatment with multi-currency conversion, and every surface (dashboard, API, shared reports) exposes the same resolved statistical contract, so the number your CFO sees is the number the API returns.

Flicker and tag weight

AB Tasty's documentation, as of our July 2026 check, describes a blended synchronous and asynchronous tag and recommends keeping it under 120KB; the tag grows as you add active campaigns. Its anti-flicker option is a page-hiding snippet you add to your source code manually, and AB Tasty's own support docs recommend against using it.

Otter's SDK is about 32 KB gzipped and loads async. The recommended install snippet includes a one-line hide style that the SDK removes as soon as variants are applied, with a three-second failsafe so a slow network can't leave a page hidden. It's a simpler system with fewer knobs, which is rather the point.

GA4 integration

AB Tasty's GA4 integrations import GA4 audiences for targeting (with a roughly 24-hour sync delay, per its docs) and push campaign data into GA4 for analysis there. They don't use your GA4 conversion events as goals inside AB Tasty reports.

Otter can: existing GA4 conversion events plug in directly as experiment goals, next to Otter's native pageview, click, custom-event, DataLayer-event and revenue goals.

When Otter is the better AB Tasty alternative

Otter fits teams whose need is A/B testing rather than a full experience platform: visual A/B/n tests, split URL tests, targeted personalization, revenue per visitor and average order value for every variant, GA4 goals, and a REST API and MCP server on every plan, for $39 to $149 a month. It doesn't do product search, recommendations, feature flags or AI audience scoring. If those matter, AB Tasty, or Wingify more broadly, is the better fit.
