## What it is
A Go library for building monitorable binaries that support graceful zero-downtime restarts and self-upgrading. It uses a small master process to exchange listening sockets with a child process, playing nicely with standard process managers like systemd and supervisor.

## Use cases
- self-upgrading go binaries
- zero downtime restarts for go servers
- graceful restart without dropping connections
- hot swap binary under systemd
- auto-update application binary from http url

## When to avoid
- your application is not a Go binary
- you don't need graceful restarts or self-upgrading
- you prefer external orchestration tools to handle upgrades

## Facets
- artifact type: library
- maturity: active
- function: deployment, concurrency, http-server
- domain: developer-tools, backend
- platform: go, cross-platform
- tags: self-upgrading, graceful-restart, zero-downtime, process-management, hot-reload, devops, linux
