4 ARM64 cores, 24GB of RAM and 200GB of storage, and some other resources and older x86, for the low low price of free. 10TB outgoing limit, no incoming limit as far as I know. You can setup one or many VPS using the resources.

I have a a full media stack running on one - Plex, Tautulli, Sonarr, Radarr, NZBGet, Qbittorrent, Jackett among other services like Portainer, YTDL, Traefik. I've seen 8+ streams with 4 or 5 720p transcodes, the CPU is pegged but it keeps up.

For storage I use a combo of services. Rclone, mounting a remote google drive to /mnt/remote. Cloudplow, takes stuff from /mnt/local folder and directly uploads to the remote drive via gdrive API using the same rclone config. And mergerfs, takes the /mnt/remote and /mnt/local folders and combines them into a /mnt/merged folder. The /mnt/merged folder is the main folder for media, downloads, etc. Any writes are first stored in /mnt/local.

I describe that setup to demonstrate the capacity of a free service, of course much less complex for a seedbox.
