Zizq
A job queue that is one binary and brings its own durable storage
Emerged finds new products worth a look, daily — what’s new today
If you run jobs across machines that lose contact with each other, it offers scheduled, encrypted execution with no central server to fail.
Gorgona is a peer-to-peer system written in C for sending encrypted messages and running commands on remote machines at scheduled times. Messages are hash-chained and time-locked, so they only unlock when due, and the mesh is built to keep going through network partitions without a coordinator. It ships as Debian packages and a Docker image, or you can build it with make and OpenSSL. The README says which parts are ready: disk storage is marked tested for production, memory-only mode is experimental. BSD-3-Clause.
