And if you just need a great forge for your company's dev teams you are all good to go. OTOH if you self-host a popular FOSS project then all of the network effects of hosting your repo on Github are gone. If you are a quite large project, such as Fedora who chose Forgejo [0] then it is fine to have a dedicated forge. If your small library repositories are hosted on single-person or small community self-hosted instances, then there is a lot of benefit if the forges hooked into this larger software development social network.
There are a couple more among public Forgejo instances [0]. For instance, though it is not very clear what they offer exactly, CodeFloe [1] mentions priced tiers in their FAQ.
> The priced tiers only exist to cover additional hardware costs of individual users which require extended resources for storage and CI/CD (CPU/Mem) in a transparent manner.
Sadly, as soon as I open the site in a private window with access to Notifications denied, a full page error screen about "Odoo Client Error" appears asking you to report... something.... to someone...? Not a good look at all.
