In plain words

NAB is a benchmark framework for evaluating anomaly detection algorithms on time-series data. Designed for developers and researchers working with anomaly detection systems, it provides standardized datasets and evaluation metrics to test algorithm performance. The tool enables consistent comparison across different detection approaches and helps identify which methods work best for specific anomaly detection use cases.

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
