Error correction and validation
Improve reliability with validation, correction, and safe rendering.
OpenUICloudFormerly C1 API
Production-ready API for AI native products
Stream production-ready UI components directly from your LLM responses.
const { OpenAI } = require('openai')
// Create OpenAI client with Thesys endpoint
const client = new OpenAI({
apiKey: process.env.THESYS_API_KEY,
baseURL: 'https://api.thesys.dev/v1/embed'
})
// Now use the client for your AI requests
const response = await client.chat.completions.create({
model: '<model-name>',
messages: [
{ role: 'user', content: 'Hello, world!' }
]
})How does it work?
OpenUI Cloud is an API layer on top of LLMs that builds adaptive UIs in real time. It turns responses from your model into live interfaces using our React SDK.
Data Integration
Turn outputs from APIs, databases, MCP servers, and tools into usable UI.
Custom components
Bring your own React components, design system, and UI patterns.
Reliable model fallbacks
Ensure stability when models fail, slow down or respond incompletely.
Bring your own LLM key
Use your own provider API keys and keep full control over model access and spend.
Low-latency rendering
Stream responsive UI components in real time, so experiences feel fast and natural.
Observability
Track token usage, latency, errors, and generation costs across models.
Stateful developer experience
Use stateful endpoints that preserve context, actions, and UI state across interactions.
Scales across every surface
Render Generative UI across chat, apps, widgets, and dashboards, and scale without rebuilding your frontend stack.
See what developers are building
Explore how developers are turning model outputs into structured, interactive applications connected to business data, tools, and real user workflows.
AI Analytics Agent
Turn data questions into live insights in minutes. Connect databases, warehouses, or tools like Mixpanel and let users query metrics in natural language.
AI Knowledge Search
Surface precise answers from docs, websites, and knowledge bases with cited summaries, cards, and suggested next steps, no scrolling through links.
Customer Support Agents
Guide customers through support, onboarding, and purchase flows with adaptive UI generated in real time.
Personalized Dashboards
Create workflows for operators, sales, and support teams without rebuilding every interface by hand.
AI Reporting Agents
Let agents collect inputs, review results, and complete tasks through interactive product surfaces.
Built for production-scale Enterprise use
Enterprise-grade security
SOC 2, ISO 27001, and GDPR compliant.
Zero data retention for training
Your data is never used to train models.
Flexible deployment options
Fully managed deployments in your own cloud environment.
Enterprise support & reliability
SLAs, proactive monitoring, and 24/7 support.

OpenUI is the open-source framework that provides the language, runtime, and tooling for building Generative UI. OpenUI Cloud builds on top of OpenUI with a fully managed platform designed for production use. It provides hosted infrastructure, stateful execution, observability, validation, model orchestration, reliability guarantees, and scalable deployment out of the box. Teams get the flexibility of OpenUI without the operational overhead of running it themselves.
Yes. OpenUI Cloud is designed to integrate with the tools and infrastructure you already use. It works with leading model providers including OpenAI, Anthropic, Google, and open-source models, and you can bring your own provider API keys to keep full control over model access and spend. It also supports frameworks and agent platforms such as LangChain, Anthropic Agents SDK, Vercel AI SDK, CrewAI, Mastra, and custom-built systems.
Absolutely. OpenUI Cloud is designed to work with your existing frontend architecture. You can register custom React components, internal design systems, reusable UI patterns, and business-specific workflows.
Production AI applications require more than model output alone. OpenUI Cloud includes built-in validation, correction, safe rendering, state management, and model fallback mechanisms to ensure interfaces remain stable and usable even when models fail, slow down, or return unexpected outputs.
The platform continuously validates generated UI before rendering, supports fallback strategies across models, preserves application state across interactions, and provides detailed observability into performance, latency, errors, and usage. These safeguards help teams deliver dependable user experiences at scale.
OpenUI Cloud enables teams to build AI-native products that go far beyond chat. Developers use it to create copilots, assistants, dashboards, workflows, forms, search experiences, internal tools, customer-facing applications, and multi-step business processes that adapt in real time.
Because interfaces are generated dynamically from user intent and connected data sources, products can move seamlessly between conversation and action. Whether you're building a simple assistant or a fully interactive application, OpenUI Cloud provides the infrastructure needed to create software that feels intelligent, responsive, and deeply contextual.
