I've been using Termius for a few years for an SSH client. Have have a lot of self-hosted servers both in my home lab and on VPSs. I'm looking to cut some costs since it's $120/year and really the main thing I use it for is syncing my SSH accounts and credentials between a laptop, a desktop, and my Android phone. So I'm looking for a new method to sync these things.

I'd prefer a single application, but I'd settle for a good, secure way to sync the credentials and recommendations for applications on Fedora and Android.

Edit: I'm OK with a one time payment application, but prefer open source or a solution I can self-host the sync server. And I don't want a subscription.
