STF (or Smartphone Test Farm) is a web application for debugging smartphones, smartwatches and other gadgets remotely, from the comfort of your browser.
STF was originally developed at CyberAgent to control a growing collection of more than 160 devices. As of July 2016 development is mainly sponsored by HeadSpin and other individual contributors.
We welcome financial contributions in full transparency on our open collective.


Thank you to all our sponsors! (please ask your company to also support this open source project by becoming a sponsor)
HeadSpin provides secure and scalable STF for iOS integrated with Appium/XCTest/Selenium/Espresso, High speed interaction Audio/Video/Game testing and AI based Root cause analysis for Performance Management. It's free to start using HeadSpin in 150+ locations worldwide! Try it out for free.
HeadSpin offers a generous monthly contribution towards STF development.

Please use our open collective or [contact us][contact-link] directly for sponsor arrangements. Both recurring and one-time contributions are most welcome. Contributions towards a specific issue or feature are also possible, and can be attributed to your company in our release notes and other related materials. Hardware-only contributions, whether new or used, are also extremely helpful and well received, especially if you find a device that doesn't work. Please see our donation transparency report for past hardware contributions.

While normal for many open source projects, STF is quite heavy on the hardware side, and is therefore somewhat of a money sink. See how to become a sponsor if you or your company would like to support future development.
We're also actively working to expand the team, don't be afraid to ask if you're interested.
Here are some things we are planning to address ASAP.
We highly encourage open participation in the community. However, if you're running a business that uses STF or would like to use STF, you may sometimes want to have an expert, i.e. one of the original developers or a skilled contributor, work with you to set up a prototype for evaluation purposes, add support for new or old hardware, figure out an issue, fix a bug or add some new feature. Our services are similar to FFmpeg's. [Contact us][contact-link] with details and we'll see what we can do.
Availability is limited and tied to individual developer's schedules.
As the product has evolved from an internal tool running in our internal network, we have made certain assumptions about the trustworthiness of our users. As such, there is little to no security or encryption between the different processes. Furthermore, devices do not get completely reset between uses, potentially leaving accounts logged in or exposing other sensitive data. This is not an issue for us, as all of our devices are test devices and are only used with test accounts, but it may be an issue for you if you plan on deploying STF to a multiuser environment. We welcome contributions in this area.
Note that you need these dependencies even if you've installed STF directly from NPM, because they can't be included in the package.
On Mac OS, you can use homebrew to install most of the dependencies:
brew install rethinkdb graphicsmagick zeromq protobuf yasm pkg-config
On Windows you're on your own. In theory you might be able to get STF installed via Cygwin or similar, but we've never tried. In principle we will not provide any Windows installation support, but please do send a documentation pull request if you figure out what to do.
We also provide a Docker container in the Docker Hub as openstf/stf. You can use our Dockerfile as guidance if you'd prefer to do the installation yourself.
You should now be ready to build or run STF.
Note that while Mac OS can be used for development, it doesn't provide a very reliable experience in production due to (presumed) bugs in ADB's Mac OS implementation. We use CoreOS but any Linux or BSD distribution should do fine.
As mentioned earlier, you must have all of the requirements installed first. Then you can simply install via NPM:
npm install -g stf
Now you're ready to run. For development, though, you should build instead.
After you've got all the requirements installed, it's time to fetch the rest of the dependencies.
First, fetch all NPM and Bower modules:
npm install
You may also wish to link the module so that you'll be able to access the stf command directly from the command line:
npm link
You should now have a working installation for local development.
STF comprises of several independent processes that must normally be launched separately. In our own setup each one these processes is its own systemd unit. See DEPLOYMENT.md and Setup Examples if you're interested.
For development purposes, however, there's a helper command to quickly launch all required processes along with a mock login implementation. Note that you must have RethinkDB running first.
If you don't have RethinkDB set up yet, to start it up, go to the folder where you'd like RethinkDB to create a rethinkdb_data folder in (perhaps the folder where this repo is) and run the following command:
rethinkdb
_Note: if it takes a long time for RethinkDB to start up, you may be running into rethinkdb/rethinkdb#4600 (or rethinkdb/rethinkdb#6047). This usually happens on macOS Sierra. To fix this on macOS, first run scutil --get HostName to check if the HostName variable is unset. RethinkDB needs it to generate a server name for your instance. If you find that it's empty, running `sudo scutil --s
