Mobile development for the Wikimedia projects centers around two main focal points: Mobile Web & Apps. Mobile Web refers to any of the tools that are used to power while Apps refer to the applications that are currently available on iOS and Android.

Key resources[edit]

  • MobileFrontend extension for MediaWiki (the code that powers Wikimedia's mobile sites)
  • MobileFrontend API
  • MediaWiki core API

Please use bug reports to track progress and make comments.

Mobile Web[edit]

The main mobile browsing experience on all the Wikimedia projects is controlled by an extension named MobileFrontend. It's written in PHP and is currently responsible for all the device detection, rendering, and custom content delivered to mobile devices. It's currently in very active development as the main piece of WMF mobile infrastructure.


Some of our users prefer the simplicity of having an app on their smart phone to quickly access Wikipedia. To support these users we've developed both a native iOS app and a Android app.

Third party Apps[edit]

Identifying your App[edit]

We recommend and encourage third party applications to properly ID themselves by setting a distinct user agent when sending requests. This allows us to identify your app traffic distinctly from anyone else in case any problems arise. To do this easily please set your UA consistent with your app. The supported format is

App name / App version

ex. 'WikipediaMobile' ~ 'Wikipedia Mobile/2.0'

Mobile companies[edit]

Professional mobile developers can get involved individually in any of the tasks listed above, and here is more:

  • If you maintain a mobile app using the Wikimedia content or API, you can make sure that it is listed and updated at the Catalog of Mobile Apps.
  • If you maintain a mobile browser or a mobile platform, you can include Wikimedia web pages to your test rounds and we are looking forward to get your feedback and bug reports. You can also keep your information up to date in the Table of Browsers Supported and the Table of Languages Supported.
  • Consider the contribution of developer resources to Wikimedia projects fitting in your roadmap. The Wikimedia Foundation can help your developers getting involved efficiently in the community work.
  • Are your mobile customers happier thanks to the fantastic work of the Wikimedia community? Please consider a donation or becoming a Benefactor of the Wikimedia Foundation. Funds for specific projects fitting in our mobile strategy are welcome too.

Feedback & Support[edit]

If you have a question, just ask in the IRC channel, #wikimedia-mobile connect or email us using the mailing list.

The best way to report problems is by filing a new ticket. First time? It takes just a bit longer than sending an email but in exchange your issue is never forgotten and you get email notifications about the progress and resolution.
