Just is a fast, cross‑platform command runner that lets you define project‑specific recipes in a justfile. It provides a simple, Make‑like syntax with modern features such as argument parsing, environment loading, and shell completion.

Use cases

• run project‑specific commands defined in a justfile
• replace make for simple task automation
• execute scripts with arguments and flags from the command line
• manage environment variables via .env files for development tasks
• provide shell completion for custom commands
• organize repetitive development workflows in a single file

When to choose

• You need a lightweight, easy‑to‑learn task runner without the complexity of Make.
• Your project requires cross‑platform command execution with minimal dependencies.
• You want clear error messages and static analysis of recipe dependencies.

When to avoid

• You need a full build system with advanced dependency tracking and parallel execution.
• Your tasks involve complex build graphs that exceed Just's simple recipe model.
• You require integration with IDE-specific build pipelines that expect Make or other established tools.
