Concurrently is a Node.js process manager and concurrent process runner designed to execute multiple shell commands simultaneously within a single terminal session. It provides core primitives for managing the lifecycles of child processes, coordinating parallel tasks, and establishing communication bridges to exchange data between parent and child processes.
The tool features an ANSI terminal output formatter that styles process logs using custom prefixes, timestamps, and colors to differentiate between multiple output streams. It includes utilities for detecting terminal color depth and converting various color formats into supported ANSI colors to ensure consistent text styling and highlights.
Process governance capabilities include the ability to set execution limits, define working directories, and trigger automatic restarts upon failure. The system can also coordinate process lifecycles by automatically terminating active sibling processes when a related command exits.
