About

OpenUI is an open-source (MIT) generative UI framework for AI agents. Instead of plain text, your agent writes OpenUI Lang, a compact, streaming-first language, and OpenUI renders it progressively as real UI: charts, tables, forms, cards and layouts. Rendering is safe by default: the model can only use components you register and no generated code is executed, so your design system stays in control. A framework-agnostic core powers first-party runtimes for React, Vue, Svelte and Angular, with ready-made chat interfaces and integrations for LangChain/LangGraph, the Vercel AI SDK, Mastra, Google ADK, assistant-ui, CopilotKit, AG-UI and A2UI. In its published benchmark, OpenUI Lang uses about half the tokens of equivalent JSON UI formats, so interfaces stream faster and cost less.

About

SerpKite is a hosted Google search and web-data API for developers building AI agents, RAG pipelines, research tools, SEO workflows and applications that need current search results. A single API provides web, news, image, video, maps, places, reviews, shopping, Scholar, patents and autocomplete results, alongside webpage-to-Markdown conversion, URL extraction, site mapping, asynchronous crawling and scheduled monitors. Responses are available as structured JSON, compact JSON or Markdown for use in applications and language-model workflows. The service includes TypeScript, Python and Go SDKs, a remote Model Context Protocol (MCP) server, and documented integrations for LangChain, CrewAI, LlamaIndex and Vercel AI SDK. It offers prepaid credit packs that do not expire, as well as a free tier with signup and recurring monthly credits; failed and empty requests are not billed.
