Free plan APILinuxSelf-hosted+1
Choose OmniRepo if you need a free, self-hosted registry for varied artifact types, with scanning and upstream mirrors in one container. Look elsewhere if your deployment depends on federation, high-availability clustering, an in-process scheduler, or OIDC or LDAP authentication.
