Codeberg is for FOSS repos only, and you need to submit an application before using their CI: https://codeberg.org/Codeberg-e.V./requests

It is, but Codeberg is only for free and open source projects.

until its not.

Every company or entity changes over time. Codeberg is great, but with more people using it for free, without donating, and worse, more people abusing the service with some bs AI generate code, malware, etc, more expensive will get to keep it running.. for now they have money, but as e.V in Germany, you survive either from members or from donations.. So use Codeberg, but most important, support it!
