See what high-converting companies are testing, before you launch yours.
ABWatcher monitors the public pages of 1,000+ curated brands, detects live A/B tests, surfaces rare CRO gems, and turns it all into ranked test plans for your own site.
Free forever for 10 watched companies. No card required.
Hottest tests, this week
Live experiments across the pool
Annual toggle now defaults on, monthly price hidden until clicked.
New three-line headline replaces the ‘Built for speed’ opener with task imagery.
Primary button copy A/B: ‘Start building’ vs ‘Try Webflow free’.
Daily crawl across 1,000+ brands
We re-snapshot the highest-converting pages of curated companies every day, isolating viewport, geo, and fingerprint per visit.
Detect real experiments
Vendor SDK fingerprints (Optimizely, VWO, Statsig, …), same-run variance, and week-over-week diffs flag actual tests, not template noise.
AI reads the test for you
A vision pass over both variants gives you the hypothesis, the surface (hero, pricing, CTA, form…), and the takeaway in plain English.
Why ABWatcher
Stop guessing. Start shipping the right bet.
Most teams burn weeks on experiments that never move the needle. ABWatcher rewires how you decide what to test next.
Without ABWatcher
- You guess what to test next, then defend the call in a roadmap meeting.
- You screenshot competitors and lose the context two weeks later.
- You read CRO blog posts citing tests from 2019.
- Half your experiments stay flat. You can't tell if the idea or the variant was wrong.
- The teams with bigger budgets keep pulling ahead.
A research team that runs while you sleep
- Wake up to a feed of live experiments from teams with serious testing budgets.
- Each test gets a plain-English hypothesis, surface, and takeaway.
- CRO gems hand-pick the patterns you'd never see in a blog post.
- Add your own site: get ranked A/B test plans grounded in real data.
- Spend your sprint shipping the bet most likely to win.
The product
Three jobs, one workspace
Watch live A/B tests across 1,000+ websites
We crawl curated brands every day with isolated browser fingerprints, planted vendor SDK cookies, and rotating viewports. When a hero, pricing, CTA, or form diverges across visits or against last week, we capture both variants and analyse them.
- Vendor SDK fingerprints (Optimizely, VWO, AB Tasty, Statsig, more)
- Same-run variance + week-over-week diff detection
- Side-by-side viewer with surface, hypothesis, and takeaway
Analysis
Hero CTA copy changed from “Get started” to “Try free for 14 days”. Variant adds a benefit subline.
Rare, hand-curated conversion patterns
Not every insight comes from a live A/B test. Some patterns only show up when you stare at a thousand landing pages. Our analyser surfaces gems: unusual pricing layouts, social-proof tricks, onboarding nudges, the kind of thing nobody writes a blog post about.
- Standalone analysis per page, no variant required
- Tagged by surface so you can browse by hero, pricing, form…
- Filter by industry, business model, segment, region
Customer logos animate in only after the hero is read, not on first paint.
Quote uses real customer logos as currency markers next to volume tiers.
First-record CTA fires a Loom of the founder explaining the next step.
Generate A/B test plans for your own site
Add your URL. We crawl it, pull the most relevant historical detections from our database, and feed both to our analyser. You get a ranked list of A/B tests to run, each with a hypothesis, the surface it targets, and the precedent that inspired it.
- Grounded in real experiments from the curated pool
- Ranked by predicted impact, not vibe
- Re-run any time, includes pages and the freshest detections
Default the annual toggle on; reveal monthly only after click.
Replace headline with a 6-word outcome (not feature) line.
Move customer logos above the fold, but only after hero is read.
