About:
wait4x is a command-line utility designed to wait for a specific port or service to become available or reach a desired state. It helps prevent race conditions in container orchestration and CI/CD pipelines by ensuring dependencies are ready before proceeding. The tool supports TCP, HTTP, and other protocols with configurable timeouts and intervals.

Key Features:

Supports TCP, HTTP, and ICMP checks
Configurable timeouts and retry intervals
Zero dependencies (static binary)
Docker and CI/CD friendly

Use Cases:

Waiting for database containers to be ready in Docker Compose
Ensuring API services are up before running integration tests
Health checking in Kubernetes init containers

Alternatives:

dockerize – Dockerize is Docker-specific, while wait4x is a standalone binary
wait-for-it – wait-for-it is bash-based; wait4x is faster and supports more protocols
