what tool are you running that management doesn't know about

i have a headless ubuntu vm running on an old optiplex under my desk that does more useful work than half the stuff we actually have budget for. it runs uptime kuma for monitoring because the "enterprise monitoring solution" management bought has a 45 second page load and nobody checks it. it runs a grafana dashboard pulling metrics from our switches that i use more than the vendor's own management portal. and it runs a cronjob that checks ssl cert expiry dates and emails me two weeks before anything lapses because we got burned by that twice before i set it up.

none of this is approved. none of it is in any documentation. if i left tomorrow nobody would know it exists and things would start breaking within a month.

what's your shadow IT that's quietly holding things together?
