This tool allows you to open logs recorded by Betaflight's Blackbox feature. You can seek through the log to examine graphed values at each timestep. If you have a flight video, you can load that in as well and it'll be played behind the log. You can export the graphs as a WebM video to share with others. Due to restrictions in the chrome web store, this version is only installable in ChromeOS. A standalone version for all other supported platforms is available for download from https://github.com/betaflight/blackbox-log-viewer/releases.
