About this extension

Live reload A/B test variations from the AvsB CLI

Read the publisher’s full description

▎ AvsB Dev Tools gives developers full visibility and control over A/B experiments running on their site. ▎ Live variation preview — Connect to the AvsB CLI dev server and see CSS and JavaScript changes instantly as you edit. CSS updates apply without a page reload; JS changes can be applied via reload or experimental hot injection. ▎ Variation switching — Switch between variations on any active experiment with one click. Works in both dev mode (CLI-compiled variations) and live mode (production experiments served by the AvsB snippet). ▎ Event monitoring — See every tracked event in real-time: exposures, clicks, page views, custom events, and segments. Each event shows its type, experiment, and timestamp. ▎ Snippet detection — Automatically detects the AvsB snippet on the page and pulls in live experiment data from your project's datafile. ▎ SPA support — Maintains injected variations and tracking across client-side navigations in single-page apps. ▎ Error overlay — Compilation errors from the CLI appear directly on the page so you can fix issues without switching windows. ▎ This extension is for developers using the AvsB A/B testing platform. It requires an AvsB account and project to function.
