A Go library for gracefully restarting network services without dropping existing connections, by spawning a new process and transferring listeners to it. It supports systemd integration and guarantees no old code keeps running after a successful upgrade.

Use cases

• zero-downtime deployment of a Go network server
• reload configuration without dropping connections
• graceful process upgrade on SIGHUP
• transfer listening sockets to a new binary
• integrate graceful restarts with systemd

When to choose

• you run a long-lived Go network service on Linux or macOS and need zero-downtime restarts
• you want socket handoff to a new process with a grace period for initialization
• you deploy via systemd and want ExecReload-based upgrades

When to avoid

• your service runs on Windows or other platforms outside Linux/macOS
• you use a container orchestrator that already handles rolling restarts
• you only need graceful shutdown, not full process replacement
