Project mention: Show HN: NoteDiscovery – Free Self-Hosted Alternative to Notion/Obsidian | news.ycombinator.com | 2025-11-11
GitHub: https://github.com/gamosoft/NoteDiscovery
Please bear in mind it's in VERY early stages so it doesn't get even close to what the excellent Obsidian can do, but for the time being it's more than enough to suit my personal needs, so depending on my availability I may be adding more features. ;-)
I really hope you like it!

forwardemail.net
Privacy-focused encrypted email for everyone. All-in-one alternative to Gmail + Mailchimp + Sendgrid.
You do not need a mailbox provider to own claude@yourdomain.com. With custom-domain forwarding, your domain's MX records point at a forwarding service, and any mail to an alias you define gets relayed to a real inbox you already have. The one I use is Forward Email, an open-source, privacy-focused email forwarding service (yes, a real company, the whole product lives at forwardemail.net), mostly because the entire thing is a clean REST API, so I can mint an address without ever opening a dashboard. Their REST API docs cover every endpoint, and the FAQ walks the DNS setup.
