Yes, we're ABTestly, so read this knowing who wrote it. We've kept every claim checkable against both companies' live sites, and we've included a real section 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+ integrations, multivariate testing, and an agency ecosystem. Choose ABTestly if you want code-first experiments, edge delivery, fully transparent statistics, and the same tested-user volume at roughly half the price.

Where Convert is genuinely better
- The visual editor. Marketers can build and QA variants without a developer. ABTestly has nothing comparable — our experiments are JSON.
- Breadth of testing. Multivariate, multipage, split URL, full-stack and feature flags (Pro). ABTestly does A/B testing.
- Integrations. 90+ one-tag integrations against our single native GA4 connection.
- Sequential testing. Convert Pro lets you monitor results continuously with correction. We run fixed-horizon tests today; sequential is on our roadmap, not in the product.
- Maturity and ecosystem. A decade-plus of operation, certified agency partners, published compliance certifications, phone support, SSO, and QA tooling (QA Wizard, live logs, preview/forced variation URLs).
- Principled company. Convert honors legacy pricing, never forces upgrades, and funds climate programs. Credit where due.
Where ABTestly is better
- Price per tested user. Same 100K MTU: $179/mo vs Convert Growth's $399/mo — about 55% less. Billed annually: $143/mo vs $299/mo — about 52% less. At 500K MTU, ABTestly Business is $399/mo; Convert prices that volume on its slider above the Growth tier.
- Code-first workflow. Experiments are JSON: version-controlled, diffable, reviewable. No editor state living outside your repo.
- Edge delivery. Config is served from Cloudflare's edge in 300+ cities with no origin round-trip, and the variant is applied on first paint.
- Snippet footprint stated up front. ~10KB gzipped runtime, loader under 1.5KB — published on our pricing page and docs, so you can hold us to it.
- Statistical transparency. The entire methodology — visitor dedupe, CI math, verdict thresholds, SRM detection — is public. Nothing is declared a winner under 95% confidence, and we deliberately don't offer 90% as an alternative threshold.
- Overage policy. Going over your MTU limit never generates a charge. Convert's overage billing is optional but defaults to $399–699 per block.
- A permanent free plan instead of a 15-day trial, plus a 30-day money-back guarantee on paid plans.
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'd rather pay $179 than $399 for the same traffic (our pricing).
Genuinely unsure? Run both for a week — our free plan plus their trial costs nothing, and our SRM check and public methodology make 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're earlier in the search.

What does Convert have that ABTestly doesn't?
A visual editor, multivariate and multipage testing, full-stack experimentation and feature flags (Pro), sequential testing today, 90+ 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 doesn't?
A permanent free plan instead of a 15-day trial, no overage charges ever, a fully published statistics methodology (95% CI on every lift, SRM chi-square check, no verdict below 95% confidence), a code-first JSON workflow that lives in version control, edge delivery from 300+ cities with a ~10KB gzipped snippet, a 30-day money-back guarantee, and roughly half the price at the same tested-user volume.
Can I validate ABTestly against Convert before switching?
Yes — run the same test in both tools simultaneously for a week on the free plan and compare visitor counts, conversion rates, and the SRM check before committing. The migration guide covers the side-by-side setup step by step.
