There are a number of potential approaches to applying A/B testing tools to Gatsby websites.
Traditional A/B testing tools can slow down your site, and in general don’t work as well with statically generated HTML pages.
However, there are several potential approaches:
Use branch-based A/B testing. For teams of developers without any content editors using a CMS, tools like Netlify’s branch-based A/B testing can work quite well with Gatsby.
Edge-based page splitting. Some JAMStack vendors like Outsmartly and Uniform have edge CDN integrations that allow them to serve multiple versions of a page, enabling personalization and A/B testing without a performance hit.
