| Summary | Split built a feature management and experimentation platform that combines feature flags with A/B testing so engineering and product teams can roll out features safely and measure business impact in a single system. Acquired by Harness in June 2024, the product continues as Harness Feature Management & Experimentation (FME). | AI SDK UI is Vercel's open-source frontend toolkit providing framework-agnostic hooks (useChat, useCompletion, useObject) for React, Vue, Svelte, Solid, and Angular that handle streaming chat state and generative UI interactions. It is the UI layer of the broader Vercel AI SDK, enabling developers to build AI-powered chat and completion interfaces without managing low-level streaming logic. |
