On stage in Los Angeles, Douglas and her team talked about how Fabric can help developers build their apps, and shared lessons learned from building the software developer kits for Twitter, Crashlytics, the company's debugging and testing tool, and MoPub, its mobile ad exchange.
"One of the things that inspired us to create this platform was that we had some bumps along the road ourselves when we were creating our mobile app," Douglas told developers, referring to the company's struggles with the "fail whale," and the solution it found in its acquisition of Crashlytics.
Developers' feedback at Thursday's event was largely positive. "There's a lot of people, a lot of companies here, the mingling has been pretty amazing," said Sergio Trevino, a senior software engineer at HR Cloud, software service for human resources professionals.

"I need more tips, you know, we're not very familiar with the platform, but we're evaluating our new technologies that we're gonna use, and this is definitely one of them. ... There are many services out there, but if we can just integrate it into one place, I think that's pretty valuable for our business."
