ntfy.brrl.net - Device Push Notifications ntfy.brrl.net

I've decided to self-host yet another service. This time it is [NTFY](ntfy.sh). Simple HTTP based push notifications for your devices. https://ntfy.brrl.net/ Feel free to use it. Feedback is welcome. I use it to notify me about successful logins on one of my servers, failed backups, results of cron jobs and so on. One simple HTTP request is all you need.

board.brrl.net — Collaborative whiteboard https://board.brrl.net/

Sometimes I just need a simple whiteboard for **troubleshooting or brainstorming sessions**. I've decided to self-host a whiteboard with collaboration function. I am going to give [whitebophir](https://github.com/lovasoa/whitebophir) a try. Feel free to use it too! - free - no ads - no tracking --- Disclaimer: the data is **not** encrypted and I - as provider - could look into them. Not optimal for permanent boards as I plan to reset it once a month (not sure yet).

I've added a status page with #uptimekuma. I want to get used to it for now. It is currently running on the same server as the rest of the services, which is not optimal. Additionally adding some more sensors at some point.
