About LoggiFly
LoggiFly is a lightweight, MIT licensed Python tool that watches Docker container logs for predefined keywords or regular expressions and sends alerts through Ntfy, Apprise, or a custom endpoint — built for self hosters and small operations teams who need to know when a container starts misbehaving without sitting in front of a terminal.
