Aeterna

Lightweight, self-hosted dead man's switch that releases your messages if you stop checking in.

Webfreeglobal

Aeterna is a free, open-source, self-hosted dead man's switch: a user writes messages and checks in regularly, and if they stop checking in, those messages are released to chosen recipients. It's aimed at people who want a private way to plan for digital legacy or emergency notifications without trusting a commercial third-party service with such sensitive content.
