Ship a command as a standalone binary that updates itself peer-to-peer. swap is an applied demonstration of a peer-to-peer installable self-updating single-operation program. This is the first in our Ecosystem Spotlight series, looking at the libraries, tools and applications growing out of the Ecosystem of Pears.

A few weeks ago we shared the story of how Pear has evolved from a single application platform to an embedded runtime supported by CLI tooling. Today those changes are officially live in Pear CLI v3.0.0. We have also completely reworked our documentation so getting started on Pear or transitioning to the new architecture is easier.

What if a terminal application could update itself without relying on servers, package registries, or centralized infrastructure? Introducing Hello Pear Bare, a new boilerplate for building standalone Bare executables with peer-to-peer over-the-air updates built in. Package your application and runtime into a single binary, distribute it anywhere, and let updates flow directly between peers. This article explores the architecture behind the next generation of peer-to-peer software distribution.
