Bowser

A WebRTC browser for iOS developed in the open. Bowser is built on top of OpenWebRTC.

Bowser logo

App Store

Bowser is not only Open Source, it is also available as a free download on the Apple App Store. When improvements have been made to Bowser or OpenWebRTC new versions for the App Store are published by Ericsson Research.

Developing for Bowser

Tips and other resources can be found on the wiki page Developing for Bowser.

Extension of UIWebView

Bowser is based on the official UIWebView provided by the platform and the WebRTC API's are implemented with JavaScript that is injected into web pages as they load, the injected JavaScript code is using remote procedure calls to control the OpenWebRTC backend.

The plan is to move to the WKWebView, introduced in iOS 8, as soon as possible.

Video rendering

Mobile Safari on iPhone displays <video> elements only in fullscreen. This severely limits the UI of your apps, especially when designing video communication apps using WebRTC. Bowser goes beyond that and allows you to fully customise and manipulate <video> elements using CSS and JavaScript.

Building

To build Bowser you need a completed build of OpenWebRTC, Xcode and the iOS SDK. The build itself is pretty simple as we have set up the header/library search paths to expect that you cloned Bowser alongside OpenWebRTC. As long as you have:

/path/to/bowser
/path/to/openwebrtc

...then you shouldn't have any problems with just opening the Xcode project and building.

Debugging WebRTC scripts

As Bowser is using the official UIWebView that is provided by the iOS platform you can use Apple's Web Developer Tools to debug your WebRTC scripts. It is also possible to use Safari on OS X to debug Bowser. The details are described in this blog post.

Background

Bowser was originally developed by Ericsson Research and released in October of 2012, for both iOS and Android devices. Back then Bowser was the world's first WebRTC-enabled browser for mobile devices. Bowser was later removed from the Apple App Store and Google Play but was resurrected and released as Open Source together with OpenWebRTC.

Bowser
A WebRTC browser for iOS developed in the open. Bowser is built on top of OpenWebRTC.

App Store
Bowser is not only Open Source, it is also available as a free download on the Apple App Store. When improvements have been made to Bowser or OpenWebRTC new versions for the App Store are published by Ericsson Research.

Developing for Bowser
Tips and other resources can be found on the wiki page Developing for Bowser.
Extension of UIWebView
Bowser is based on the official UIWebView provided by the platform and the WebRTC API's are implemented with JavaScript that is injected into web pages as they load, the injected JavaScript code is using remote procedure calls to control the OpenWebRTC backend.
The plan is to move to the WKWebView, introduced in iOS 8, as soon as possible.
Video rendering
Mobile Safari on iPhone displays <video> elements only in fullscreen. This severely limits the UI of your apps, especially when designing video communication apps using WebRTC. Bowser goes beyond that and allows you to fully customise and manipulate <video> elements using CSS and JavaScript.
Building
To build Bowser you need a completed build of OpenWebRTC, Xcode and the iOS SDK. The build itself is pretty simple as we have set up the header/library search paths to expect that you cloned Bowser alongside OpenWebRTC. As long as you have:
/path/to/bowser
/path/to/openwebrtc

...then you shouldn't have any problems with just opening the Xcode project and building.
Debugging WebRTC scripts
As Bowser is using the official UIWebView that is provided by the iOS platform you can use Apple's Web Developer Tools to debug your WebRTC scripts. It is also possible to use Safari on OS X to debug Bowser. The details are described in this blog post.
Background
Bowser was originally developed by Ericsson Research and released in October of 2012, for both iOS and Android devices. Back then Bowser was the world's first WebRTC-enabled browser for mobile devices. Bowser was later removed from the Apple App Store and Google Play but was resurrected and released as Open Source together with OpenWebRTC.
