Hello.

This post explores browser compatibility data, focusing on features present in some browsers but not others. I've created a tool, "Not yet Stable," to visualize these differences and help developers understand the current web platform landscape. While high-level comparisons are interesting, the real value lies in identifying smaller, unexpected compatibility issues that can cause frustration. The tool allows for granular comparisons between specific browsers (e.g., Chrome vs. Firefox, Safari vs. Firefox) to pinpoint these inconsistencies. I've observed significant discrepancies in media-related features, such as Web Codecs API, Picture-in-Picture, and MediaStreams. The goal is to leverage this data for better understanding and ultimately improve web compatibility.
