Twitter announced the mobile developer tools suite Fabric in October 2014.
Fabric was unveiled on October 22, 2014, at Twitter’s Flight developer conference in San Francisco. Twitter described it as a modular mobile platform designed to help developers handle several recurring challenges when building and operating apps, including stability, distribution, revenue, and identity.
The suite brought together products and services associated with Twitter and its acquisitions. Crashlytics supplied crash reporting and stability tools, MoPub supported mobile advertising and monetization, and Twitter Kit helped developers add Twitter sign-in, embedded content, and related functionality. Fabric also introduced Digits, which enabled phone-number-based app authentication.
Fabric was not a competing mobile app framework such as PhoneGap, nor was it a standalone backend service like Parse or Firebase. It was a collection of software-development kits and services intended to be added to mobile applications with relatively little code. Twitter later agreed to sell Fabric and Crashlytics to Google in 2017, and Google eventually folded the products into its developer ecosystem.
