Today Snapchat finally gets a true developer platform, confirming TechCrunch’s scoop from last month about Snap Kit. This set of APIs lets other apps piggyback on Snap’s login for signup, build Bitmoji avatars into their keyboards, display public Our Stories and Snap Map content, and generate branded stickers with referral links users can share back inside Snapchat. Snap Kit’s big selling point is privacy — a differentiator from Facebook. It doesn’t even let you share your social graph with apps to prevent a Cambridge Analytica-style scandal.

Launch partners include Tinder bringing Bitmojis to your chats with matches, Patreon letting fans watch creators’ Stories from within its app, and Postmates offering order ETA stickers you can share in Snapchat that open the restaurant’s page in the delivery app. Developers that want to join the platform can sign up here.
