ABTestly

ABTestly is a code first A/B testing platform for technical CRO and growth teams. This extension is the capture tool for ABTestly Signals, its AI conversion audit. Open the side panel on a page you want analysed. The extension takes a set of screenshots at desktop and mobile widths and reads the page's structural evidence, then sends that capture to your ABTestly account. Signals grades the evidence, generates hypotheses, argues against each one in an adversarial falsification pass, and ranks what survives. The output is a reviewable starting point, not a roadmap. Every hypothesis carries the evidence behind it and the condition that would prove it wrong, so your team can argue with it. What it does - Full page screenshots at multiple viewport sizes - Structural DOM evidence - Sends the capture only to your own signed-in ABTestly account - Shows a launcher button only on sites registered in your account What it does not do - It does not run experiments. Experiments run from the ABTestly web app. - It does not read pages you have not chosen to capture. - It does not track your browsing. Signals is in Beta and free during Beta. You need an ABTestly account to use the extension. Version 0.2.1: choose Quick (2 ideas) or Full backlog (6 ideas) before you scan. Scans now measure what sits above the fold on your screen, count image alt text the way Lighthouse does, and pick out calls to action more accurately.
