A fairly simple webhook service that listens to a signald socket and exposes messages via HTTP. Uses YAML for its config files. Can also send messages (replies?) using one or more template files as a basis.
A self-hosted service that pings webhooks or other URLs on a user-defined schedule. Works a little bit like cron. Can even do things every X minutes or hours, like cron.
Written in PHP, uses SQLite.

patchbay.pub is a free web service you can use to implement things like static site hosting, file sharing, cross-platform notifications, webhooks handling, smart home event routing, IoT reporting, job queues, chat systems, bots, etc, all completely cgi-bin and requiring no account creation or authentication. Most implementations need nothing but curl and simple bash snippets.
