It’s just what I use, as I’m specifically looking for something which only notifies when things aren’t able to report due to failure. Free for 20 checks which is more than enough for me.
If I were hosting it myself I wouldn’t know if my own notification system had failed (since it wouldn’t be able to report due to failure.)
For Podman you don’t need anything else other than Podman to monitor and restart failed containers:
podman-compose --podman-run-args='--health-on-failure=restart' up -d
For anything else I use https://healthchecks.io/
Why not Actual Budget, which is also self-hosted, open-source bucket budgeting based off YNAB, however it appears to be a lot more mature.
They also transparently run the project on Open Collective which I like: https://opencollective.com/actual
You can use Immich Public Proxy to share the albums without having to expose your Immich instance. You can use all the normal Immich options - password protected albums, and links that expire, etc
