ABTestly

ABTestly is an A/B testing platform built for teams that care about site performance and cost predictability. It runs on Cloudflare’s edge, ships a small inline snippet, and never auto-charges you for traffic overages.

​
What’s different about it

  • <50ms snippet impact (P95) — about 4x faster than mainstream alternatives. The snippet is small, runs synchronously, and doesn’t depend on third-party tag managers.
  • Graceful overage handling — if you exceed your monthly tracked users (MTU) limit, your already-bucketed visitors keep seeing their variant (statistical validity preserved), but new visitors stop being bucketed. You get a warning email and decide whether to upgrade. No surprise invoices.
  • No data deletion — downgrading, canceling, or being archived after 90 days of inactivity all preserve your data. Reactivation is one click.
  • Permanent free tier — 1 site, 1 active experiment, 3,000 MTU. Enough to evaluate the product on a real page.

​
Who this is for

  • CRO professionals running tests across multiple sites
  • Solo founders validating landing pages without a Convert/VWO contract
  • Agencies managing experiments for client portfolios
If you’re paying $300+/mo for VWO Growth or Convert and feeling priced out, or hitting Optimizely’s enterprise-only minimum, this is built for you.

How it works at a glance

  1. You sign up at app.abtestly.com, add your site, and paste a snippet into the <head> of your HTML.
  2. You build an experiment in the dashboard: name, hypothesis, targeting, variants, goals.
  3. You click Start. The new config propagates to all edge locations within ~60 seconds.
  4. Your visitors hit your site, the snippet decides which variant to show, and they see their assigned version on the first paint (no flicker).
  5. Real-time exposures and conversions stream into your results dashboard. Most tests need 5,000+ exposures per variant for 95% statistical confidence.
