| Summary | Harness is an AI-native software delivery platform that unifies CI/CD, feature flags, cloud cost management, chaos engineering, security testing orchestration, and reliability management into a single end-to-end DevOps suite. It embeds AI throughout to automate test selection, intelligent rollbacks, and cost recommendations for engineering teams. | 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. |
