I think it’s still alive, at least GmsCore had a new release last week

I think it’s an interesting project. However I am not a fan of their decision to omit forward secrecy, and have thus passed on using it. At least for now.

Of the top of my head, maybe either

• Logseq (should be rather like Obsidian but open source)
• Xournal++, I do not know if it has the organising features or cross note search

Can share some of my favourites

• KISS laucher
• Floris Board (keyboard, which I love to use)
• Bitwarden + Aegis (password manager + OTP)
• Eternity (for browsing lemmy)
• Mull (hardened firefox fork)
• Organic maps (maps + directions)
• Track & Graph (for tracking trends/habits)
• WebApps (running sandboxed websites)

Just begun exploring using:

• Immich (selfhosted photos solution)
• ReThink (local dns/firewall tracking blocker)

Btw, I believe Obsidian isn’t FOSS.

Haven’t tried Session, though it seemed like a good service, until I found it lacks perfect forward secrecy, which IMO seems like a bad decision. I think Berty seems interesting too, but it seems like it might take a short while before it becomes a relevant option.

Haven’t tried it but, DivestOS might also be an option.
