Google Killed Optimize in 2023. 3M Websites Lost Free A/B Testing. VWO Wants $393/mo.

When Google shut down Optimize in September 2023, an estimated 2 to 3 million websites lost their free A/B testing tool overnight.

A solo developer can build a lightweight, snippet-based A/B testing tool in two to three weeks, charge $29/mo flat, and capture the massive long tail of small businesses, indie hackers, and marketing teams that just need to test a headline or button color without signing an enterprise contract.
