The Idea

'The Web' is constantly changing, and one of the most important aspects is that it has escaped the 'desktop' and is now accessed from, well… a very wide range of devices.

Testing is an important and crucial part of designing and developing for the web these days. Listen. Repeat: Testing on real devices is an important and crucial part of designing and developing for the web these days. Diverging resolutions, varying user behaviors and differences in browser or OS combinations can neither be simulated nor ignored anymore. The best way to test new concepts of user interaction like touchscreens and gestures is to, wait for it, Test On Real Devices!

The ODL Frankfurt follows Jeremy Keith's (and also many others') initial idea of providing a wide array of devices which allows local developers to test on real appliances without breaking the bank, in turn asking them to contribute knowledge or leave their spare or test devices at the lab for others to test.


We're building a diverse collection of different web-enabled devices, aiming to cover a wide range of brands, models, OS's and combinations thereof.

By contributing a device you will help to ensure that using the web will become a better experience - for yourself, your site's visitors and everybody else. Just send us an email or ping us on twitter.

Wenn Ihr also ungenutze, alte, nicht-mehr-ganz-so-hippe, Geräte besitzt, wäre es großartig, wenn Ihr dieses als (Dauer)Leihgabe unserer Sammmlung zur Verfügung stellen würdet. Superidee!


Contact us via E-Mail, Twitter or Facebook.

Beyond our infinite gratitude and the opportunity of feeling good about yourself while supporting the local webdesign/webdevelopment community, the name and logo of your company will be implemented in the webpage as well as in the lab. Your beloved old device will be part of the ongoing improvement of everybody's user experience, and live happily ever after with it's newfound friends.

Visit us

The Open Device Lab is open to local webdevelopers and -designers.

If you would like to test on our devices: Email us at or ping us on Twitter and make an appointment a few days in advance. We're located in Frankfurt-Bornheim, close to the subway, bus and train station "Bornheim Mitte", at the office of BNT.DE Gesellschaft für interaktive Medien, Löwengasse 27E, 60385 Frankfurt, and usually we're present Monday to Friday between 11:00 and 19:00.

Are there any costs involved in using the ODL?

The use of the devices here is free of charge. We are, of course, pleased if testers provide other devices to the fleet as a permanent loan and thus support the idea.

In general, you have to distinguish two cases:

  1. Somebody uses the devices and infrastructure (WLAN) here in the Open Device Lab Frankfurt, in order to independently test a website on the present devices. In this case, use is free of charge.

  2. For us as Open Device Lab Frankfurt, costs or expenses arise through consulting or other activities. For example, we as Open Device Lab Frankfurt are asked to test a website for a third party, to provide advice, or to take special care, such as setting up a VPN connection between the test company and OpenDevice Lab. We would settle the expenses incurred here at a fixed hourly rate.----

Not in Frankfurt?

Open Device Labs are springing up all around the globe, maybe one is near your location:

If you have established an Open Device Lab we can offer you a subdomain at [location] Don't hesitate to contact us. The easiest way would be a redirection to the url of your website (it's not working for subpages like, but we can also provide a nameserver a-name record.
We do not host any kind of data and we will delete the redirection as soon as we find out that it's not an Open Device Lab website we're redirecting to. Just sayin'.

The best and foremost place to find all kind of information on the ODL movement is, you definitely should start there by submitting your lab, as we did :-)

As of 26.8.2014 our top level domain "" points towards the server of "", subdomains not included.

Support the ODL Frankfurt

Test devices, know-how transfer, hardware and software, money, word-of-mouth - there are many ways you can help us if you like.

Developers & Designers

Come testing, share knowledge, and maybe bring one of your own old test devices along - we'll happily add it to our library.

Device manufacturers

Developers need test devices to enhance their applications and by doing so enhance the user experience on these devices, which in turn benefits the manufacturers of these devices. We're looking for manufacturers who are willing to provide test devices for our ODL.

Companies & Businesses

You are a business owner, perhaps dealing in hardware or software, or web sevices - then you may support us with tools and devices needed for our infrastructure. Or maybe you're in contact with other potential supporters. Maybe we can work out a financial sponsorship and welcome you as a partner?


Even if you're not at all into this web- and mobile thing, we'd be happy for your support, maybe by treating your old and dust-gathering device (mobile phone, smart phone, tablet, game console etc pp) to a new life as a test device in our ODL, or just by spreading the world and get us some publicity, everything helps :-)

Friends and Supporters

We thank everybody who contributes something to our project, supports us with office space, decives, hardware, know-how or software licenses – you are awesome!
