Google announced the release of  a web-based tool that can be used by developers to install Android Open Source Project (AOSP) builds on recent Pixel phones and some Android development devices from the web browser, without building and flashing manually.

"In order to support developers working in AOSP we are launching Android Flash Tool, which allows developers to flash devices with builds listed on the Continuous Integration Dashboard," Android Build Software Engineer Mitchell Wills explains.
