It is a bit weird. AFAICT this isn't a hosted service. It's AGPL code you host yourself, and yet as nix23 says, at https://grommunio.com/product/ https://grommunio.com/product/ there's: > Community > max. 5 user – free With no further explanation (the site isn't very clear generally). IANAL but I don't think you can do that with AGPL. If it's AGPL licensed and you're hosting it yourself you can use it for anything as long as you abide by the terms of the license (including the "Affero" bit). It would be different if this were (A)GPL code together with a hosted service you can use free with up to 5 users, but I think that's not what this is. Edit: The thing they're selling appears to be support and limiting free support to 5 users would be fine (and generous!) but they make it clear with Community you don't get any support so I don't see any basis for restricting the number of users.
