Mutatr is an end-to-end A/B testing agent.

In practice, it connects to a repo, then:

1. Suggests A/B treatments

2. Implements variants in the codebase

3. Runs flights using synthetic personas that simulate the expected audience for your site

4. Returns attention maps to help you learn what works before going live

Funny story: Mutatr started as a YC application that got rejected, so I decided to build it anyway and open-source it
