Related, there's a suggestion in the StarlingX community at the moment about the possibility of incorporating SAP's Elektra UI ( https://github.com/sapcc/elektra ) as an alternative to Horizon: http://lists.starlingx.io/pipermail/starlingx-discuss/2020-September/009659.... Looks like it's a mix of Apache and MIT/Expat (Apache-compatible) licensed Javascript and Ruby/Rails. Given there's not really any Ruby in OpenStack proper (except for Ruby-based configuration management and maybe SDKs), I expect that may not be a great starting point for a next-generation Horizon, but it could still serve as a source of some inspiration. Also this highlights an interest from some of the StarlingX contributors in Horizon replacements, so maybe they'd be willing to contribute... or at least help with requirements gathering. -- Jeremy Stanley
