Our Git is currently self hosted on our LAN, and unfortunately it's not possible to tell Gitea to accept two different domains, but from here http://s7v2qgqpsgnak5rkrewh3gabd4h2hfluz7hpzr7mrtmscgb2pmzq2zqd.onion/indra-labs/indra you can watch it via a Tor hidden service.
Signups are of course disabled, and there's nothing particularly secret on the site but the server (my spare, budget laptop) is always on and always connected to Tor so you can for example see the white paper here:
Beware some features of the site may not work, but from a cursory check it seems it's enough to be able to view and potentially download the source code.
