What is Death Plan Switch?
Death Plan Switch is a free, self-hosted dead man's switch built for independent web developers. It runs on PHP 8.1 or newer without a database and sends a weekly email check-in. The user must press a button inside the email to confirm they are active, which prevents automated mail scanners from triggering false alarms.
If the user misses the weekly check-in, the system follows a fixed timeline. After two reminders, it contacts the designated next of kin. If the next of kin reports an issue, the system sends pre-written messages to other important contacts. The user can check in at any point to stop the process and send a cancellation notice to anyone already alerted.
The software is MIT licensed and available on GitHub. A browser installer sets up the application and generates the cron job needed for scheduling. Users supply their own SMTP credentials and should host the tool on a separate server from the sites it manages.
