## What it is
Huptime is a command-line utility that enables zero downtime restarts of unmodified programs by wrapping them and handing off listening sockets across restarts. It lets you upgrade application code via SIGHUP without dropping or rejecting client connections.

## Use cases
- restart a server without dropping connections
- upgrade application code with zero downtime
- avoid building a load balancer tier just for deploys
- continuous deployment of simple unmodified services
- reset pidfiles on service restart

## When to avoid
- you need a maintained tool with recent updates (last release 2015)
- you run complex multi-process or clustered deployments better served by orchestrators
- you need non-Linux platform support

## Facets
- artifact type: cli-tool
- maturity: abandoned
- function: deployment, networking, developer-tools
- domain: backend, self-hosted
- platform: cli
- tags: zero-downtime, hot-restart, socket-handoff, continuous-deployment, devops, linux
