Convert vs ABTestly. An honest comparison.

Convert figures verified on convert.com/pricing on 12 August 2026. Check their site for current numbers.

Yes, we are ABTestly, so read this knowing who wrote it. Every claim is checkable against both companies' live sites, and there is a real section below on where Convert beats us. Because it does, in several places.

The short version. Choose Convert if you want a mature platform with a visual editor, 90 plus integrations, multivariate testing, and an agency ecosystem. Choose ABTestly if you want code first experiments, edge delivery, transparent statistics, and the same tracked user volume at about a third less than Convert billed annually.

Where each one wins

Where Convert genuinely wins

The visual editor. Marketers can build and QA variants without a developer. ABTestly has nothing comparable.
Breadth of testing. Multivariate, multipage, split URL, full stack and feature flags on Pro. ABTestly does A/B and split URL tests with multiple variants but not multivariate, full stack or feature flags.
Integrations. 90 plus one tag integrations against our single GA4 data layer event.
Maturity and ecosystem. A decade plus of operation, certified agency partners, published compliance certifications, phone support, SSO.
Principled company. Convert honors legacy pricing, never forces upgrades, and funds climate programs. Credit where due.

Where ABTestly is better

Price per tracked user. $249 / mo Pro vs $399 / mo Convert Growth at the same 100,000 MTU tier. Billed annually: $199 vs $299, about a third less.
Code first workflow. Every variant is explicit JS and CSS. Readable, diffable, reviewable, not opaque generated selectors.
Edge delivery. Config served from Cloudflare's edge in 300 cities. Anti-flicker is available when you need pre-paint delivery.
Snippet footprint stated up front. ~27 KB gzipped runtime, loader under 1.5 KB. Published so you can hold us to it.
Three statistics engines available. Frequentist on every plan. Sequential and Bayesian on Pro. No add on to unlock either one.
Signals AI audits. The optional Signals add on scans any page, surfaces test hypotheses backed by evidence, and links each idea directly to experiment creation. Free while in Beta.
Revenue analysis and business impact. Revenue per visitor with outlier capping across all three engines (Pro), plus a projected business impact summary based on observed lift and current traffic (Business). Methodology documented.
Speed guardrails. Per variant LCP monitoring shows per variant, per device p75 LCP and warns when a variant is meaningfully worse than the baseline (Pro and up).
Mutual Exclusion Groups. Holdout cells measure incremental program lift, not just per test wins (Business and up).
No automatic overage charges. Going over your MTU never generates a surprise bill.
Permanent free plan instead of a 15 day trial, plus a 30 day money back guarantee on your first paid month.

Which should you pick?

Pick Convert if your testing program is run by marketers in a visual editor, depends on a wide integration stack, or needs multivariate testing, SSO, and formal compliance certifications today.

Pick ABTestly if your experiments are built by people who write code, your stack reports into GA4, and you would rather pay $249 than $399 for the same traffic. The Signals add on gives you AI powered page audits, and the sample size calculator helps you plan before you launch. See our pricing.

Genuinely unsure? Run both for a week. Our free plan plus their trial costs nothing, and our published methodology makes it easy to confirm the two tools agree before you commit. The migration guide covers the side by side setup, the pricing breakdown has the full cost math, and the Convert alternative page is the shorter read if you are earlier in the search.

What does Convert have that ABTestly does not?

A visual editor, multivariate and multipage testing, full stack experimentation and feature flags on Pro, 90 plus integrations, SSO, phone support, published ISO 27001 and SOC 2 certifications, EU servers, and a decade plus of operating history.

What does ABTestly have that Convert does not?

A permanent free plan instead of a 15 day trial, no automatic overage charges, three statistics engines (Frequentist on every plan; Sequential and Bayesian on Pro), a code first workflow where every variant is explicit, reviewable code, edge delivery from 300 cities with a snippet around 27 KB gzipped, a 30 day money back guarantee on your first paid month, plus Signals AI page audits (free while in Beta), revenue per visitor with outlier capping (Pro), speed guardrails (Pro), Mutual Exclusion Groups with holdout cells (Business), and a projected business impact summary based on observed lift and current traffic (Business).

Can I validate ABTestly against Convert 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. The migration guide covers the setup step by step.
