Mutatr – an open source A/B testing agent
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

Why It Matters
Mutatr automates the A/B testing process from suggestion to analysis, enabling pre-launch learning through simulated user behavior.
Key Features
- Suggests A/B testing treatments
- Implements A/B test variants in codebase
- Runs A/B tests using synthetic personas
- Generates attention maps for insights
Use Cases
- A product manager can use Mutatr to quickly generate and test different button color variations on a landing page to see which one leads to a higher conversion rate, without needing to involve developers for initial implementation.
- A startup founder can leverage Mutatr to simulate user engagement with new feature ideas by creating synthetic personas, allowing them to gather insights on potential user behavior and refine the feature before a full public release.
- A growth hacker can integrate Mutatr with their codebase to automatically suggest and deploy A/B tests for headline copy on blog posts, then analyze the attention maps to understand which phrasing resonates best with their target audience.
