Splera is a Chrome extension designed to streamline A/B testing for applications built on Replit. It automates the process of detecting UI changes and setting up experiments, allowing indie developers to focus on building rather than statistical complexities. With features like automated hypothesis generation and Bayesian statistics tailored for small sample sizes, Splera makes data-driven decisions accessible. The extension detects changes made in Replit, suggests testable hypotheses, and wires up tracking without requiring manual script adjustments.

Targeted at solo builders and indie hackers, Splera provides a complete experiment lifecycle, enabling users to pause, resume, or ship winning variants seamlessly. By leveraging Bayesian statistics, it allows for meaningful insights even with limited visitor counts, making it especially beneficial for indie applications. As a free tool during its beta phase, Splera aims to empower developers with trustworthy data to guide their decision-making process.
