Wolfia - Turn your app into a link

Hi! We’re Fabien and Naren, founders of Wolfia and former mobile developers at Facebook and Wealthfront.

Wolfia is a mobile app emulator you can access through the browser.

The pain

Teams working on a mobile app currently have to wait for it to be built and pushed to them at night. That's if they even have a nightly build setup. Most people also only have one phone, so they can never test the Android app if they have an iPhone and vice versa.

The cure

Wolfia lets developers send a link to an APK (an Android binary) that's running on an emulator accessible via the browser. You can play with the app without the need for a physical device (iOS coming soon!).

• Product Managers and Designers can use it to check that a new feature is being built up to their specs.
• Developers can use it to check if the code is running correctly.
• Founders, User Researchers and Salespeople can use it for interactive demos of the product.

The tech

We host headless (without GUI) android emulators with hardware acceleration running on AWS bare metal instances to get high performance. We use WebSockets to make a two-way connection between the browser and the emulator through ADB. The emulator's GUI is displayed on the browser via an H.264 video feed, and we relay the user's touch events back to the emulator. We use WSS to make this secure.

The story

We've been developing mobile apps for 10+ years, and in that time, the tooling has dramatically improved. Yet we found ourselves having to go and install emulators on a PM's laptop and give them commands to copy and paste on the terminal because they didn't have an android phone. Or we would have to procure test phones and wait for a build to be pushed. We built Wolfia to make this process seamless.
