LibreTech maintains a GitHub repository that aggregates these tools. Clone it to your local machine:

The tool is as “free” (GPLv3) and does not require any proprietary bootloaders or binary blobs to function. This is critical for projects like Libreboot, which avoid any non-free code even in flashing tools. libretech-flash-tool
