2 projects listed in This Week in Self-Hosted (27 September 2024): AirTrail and Hoarder. I don't use either, but good to see more self-host stuff adding OIDC!
Giving Mathesar a try for a "life CMS". I loved Notion databases for easily creating structured data and linking between items and have been trying various things to replace it. Maybe this will be it! I like that it's specifically Postgres (as that's most of my homelab). It's missing a good mobile interface and OIDC though.
