LastSignal

Self-hosted, encrypted dead man's switch for messages to loved ones

Webfreeglobal

LastSignal is a self-hosted, email-first dead man's switch: write encrypted messages for people you care about, and if you stop responding to periodic email check-ins, LastSignal automatically delivers those messages. The project explicitly offers no hosted SaaS version — self-hosting is the only option.
