Seriously awesome. I loved WakaTime for years and years, but I could no longer stomach sending private, even precious meta data, to a third-party, no matter who. Syncing is not in a stable release yet, but I believe it will be there, and will help test. What a truly amazing self-hosted decentral solution to one of the oldest, if not the oldest problem in digital life. Major respect.
