Arduino CLI is a command-line tool that provides an all-in-one interface for working with Arduino boards and compatible platforms from the terminal or programmatic interfaces.
The tool solves the problem of managing Arduino development workflows without a graphical IDE. It bundles board and library managers, sketch compilation, board detection, and upload functionality into a single command-line application, allowing developers and automation systems to interact with Arduino hardware through scriptable commands rather than GUI interactions.
Arduino CLI suits developers who prefer terminal-based workflows, those building automated build systems or CI/CD pipelines for embedded projects, and anyone needing to manage multiple Arduino-compatible boards and libraries programmatically. It works well for headless environments, server-side build automation, and integration into larger toolchains. The project is particularly valuable for teams that need reproducible, version-controlled hardware development processes.
The project maintains active development with regular updates to support new boards and platforms. Contributions are actively welcomed through documented processes for building, testing, and submitting changes. The team provides nightly builds for testing new functionality and maintains a formal security policy with a dedicated contact for reporting vulnerabilities. Documentation is comprehensive, covering installation, getting started guides, and a complete command reference.
