Hi, I am one of the co-creators of Sniptt.

We faced this ourselves countless times, and it is exactly why we created both OTS and Snip (https://github.com/sniptt-official/snip - like OTS but with the ability to persist secrets and also create shared vaults etc.).

Pleased to say that self-hosted options for both OTS and Snip are currently top of our roadmap.

Keep an eye on the repos for updates! :)
