What is ECTool? The term ECTool refers to two entirely different software utilities depending on whether your background is in hardware engineering or DevOps and enterprise automation.
Most commonly, ECTool is an open-source command-line utility used by hardware enthusiasts to interact with a computer’s Embedded Controller (EC). Separately, ECTool serves as the primary command-line interface (CLI) for CloudBees CD/RO (formerly ElectricFlow), a major enterprise deployment automation platform. 1. Hardware Utility: The Embedded Controller Interface
In consumer electronics and computer engineering, ectool is a low-level diagnostic program. It was originally created by the Chromium OS project to interact with the firmware running on small, independent microcontrollers inside laptops.

While it was designed for Chromebooks, developers like Dustin Howett have ported and adapted ectool for modular systems like the Framework Laptop. It allows advanced users to bypass the traditional BIOS or operating system abstractions to change hardware behavior directly. Key Capabilities
Because it communicates via raw port I/O protocols, ectool requires root or administrator privileges (such as sudo on Linux) and often requires disabling Secure Boot. Common tasks include: CloudBees Docs Use the CloudBees CD/RO ectool API
