What is it?
STF (Smartphone Test Farm) lets developers and QA teams debug phones, smartwatches and other devices remotely through a web browser. Devices connected over USB to a host machine appear in a shared inventory, where users can see the live screen, send touch and keyboard input, install and launch APK files, run ADB and shell commands, view logs, and browse the file system.
Beyond single-device control, STF includes a booking system that reserves device sets for users during set time windows, and a partitioning system that allocates devices to different projects or organizations. Administrators can manage users, devices and group quotas, and the project offers a REST API and Prometheus metrics for integration. Support for iOS is listed as experimental and requires a signed WebDriverAgent prepared with Xcode.
STF is deployed on a Linux host with Node.js, RethinkDB, ADB and several native libraries, or run via Docker or the npm package. The README notes that internal communication between processes is unencrypted and is designed for trusted users, so multi-user deployments need extra hardening.
