The Twilio Client contest saw five winners take home prizes after a massive two-week effort from the developer community, with entries ranging from add-ons that let users dial phone numbers directly in their browser to 3D games using Twilio Client for in-game chat. The contest aimed to test the capabilities of developers and was made possible by tools such as Koderank, which allows for online coding interviews, and RingDNA, a tool that helps improve sales by providing real-time call management and analytics.
