Show HN: Death Plan Switch, a self-hosted dead man's switch for solo devs
A developer has created a self-hosted, open-source dead man's switch designed for solo professionals to notify contacts if they become incapacitated. The system uses a weekly email check-in process to verify the user's status before alerting designated next of kin or business associates.
Why it matters
It provides a low-cost, privacy-focused solution for solo entrepreneurs to ensure business continuity and personal safety without relying on third-party cloud services.
A small, self-hosted dead man's switch for independent web developers. It emails you once a week. If you stop answering, it asks your next of kin, then tells the people who need to act.
Free. MIT licence. PHP 8.1 or newer, no database.
Every step is counted from the weekly check-in email. The spacing below is to scale.
Your next of kin says you're well. It ends there, and nobody else hears a thing.
Your next of kin says so, and your other contacts are sent their messages straight away.
At any stage, even after it fires. Anyone already contacted is told it was a false alarm.
The email goes at the same time each week, so your contacts are told at most 13 days after your last check-in. Opening a link never counts: email scanners open links, so you have to press the button.
