ShortKit

ShortKit is a Y Combinator-backed short-form vertical video platform that gives product teams a drop-in, TikTok-quality video experience without the infrastructure complexity. It ships native SDKs for iOS, Android, Flutter, React Native, Expo and Web alongside a REST API for managing content, direct uploads, live streams, in-feed surveys, analytics events and ad configuration. The platform handles adaptive-bitrate HLS transcoding, global CDN delivery across 300+ points of presence, automatic caption generation with language detection, protected/signed playback, and native ad insertion (Google Ad Manager / VAST / IMA). Developer docs are partner-gated but the Mintlify API reference and the iOS SDK are published openly on GitHub.

ShortKit publishes 5 APIs on the APIs.io network, including Ad Configuration API, Analytics API, Content API, and 2 more. Tagged areas include Company, Video, Short-Form Video, Video SDK, and Streaming.

The ShortKit catalog on APIs.io includes 1 event-driven AsyncAPI specification.

ShortKit’s developer surface includes documentation, API reference, getting-started guide, pricing, engineering blog, signup flow, sandbox, and 19 more developer resources.
