Try lf then. You can configure it to work just like ranger (see project wiki)
That post is only in regards to the CI feature. But today, even basic registration requires personal identification. You cannot even report bugs on open source projects without
Even Github does not require any personal information, so there are certainly other ways.
To add a few more details: After trying several times with different IPs and different browsers, I was able to register by providing only a mobile phone number once. Since that still requires personal information, this is still a very questionable process. (not to mention it took me a day to not be asked for a cred card)
If your IP (and possible your browser) looks "suspicious" or has been used by other users before, you need to add additional information for registration on gitlab.com, which includes your mobile phone number and possibly credit card information. Since it is not possible to contribute or even report issues on open source projects without doing so, I do not think any open source project should use this service until they change that.
