Wait4X is a lightweight, zero-dependency CLI tool (also importable as a Go package) that waits for ports or services like TCP, HTTP, DNS, Redis, MySQL, PostgreSQL, MongoDB, Kafka, and RabbitMQ to become ready. It supports customizable timeouts, exponential backoff, reverse and parallel checking, and command execution after a successful wait.

Use cases

• wait for postgres to be ready before running migrations
• block CI pipeline until redis is up
• wait for a tcp port to open in docker-compose
• check http endpoint health before deployment rollout
• wait for kafka or rabbitmq before starting consumers
• find a free port with reverse checking
• wait for dns record to propagate

When to choose

• you need a single static binary with no runtime dependencies for readiness checks
• you orchestrate multi-service startup in CI/CD, containers, or local dev
• you want to wait on many protocols and services with one consistent tool
• you need reverse checks (wait for a port to be free) or parallel checks

When to avoid

• you need full monitoring or alerting rather than simple readiness gating
• your orchestrator already has built-in readiness probes and init containers
• you need a long-running daemon or dashboard rather than a one-shot wait
