Some notes:

• This can be self-hosted. My working compose.yml is below
• Free until August, and he has a discord for feedback, but I can’t find the invite. It was in the live-stream he did.
• He said in the stream that he’s open to open sourcing the project. Just not there yet.
• He admits the licensing is a little confusing. He stressed that self-hosting does not have a storage or block limit. Also, self-hosting is possible with all licenses (I think).
• Supports macOS, Linux, Windows, iOS, and Android (in beta I think)

I have the DB, config, and thumbnails on local NVME, and storage on NFS-mounted NAS. Working fine so far.

ETA: Correction in compose file.
