Open-source frontend stack for building AI agents and copilots inside your own product
Ship a working copilot UI in minutes with drop-in components for React, Angular, Vue, iOS, and Android, or go fully headless for total control over rendering.
A general-purpose bi-directional link between your app and any agent backend, with integrations for the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, Mastra, and many more.
Agents return real UI — charts, forms, tables, and approval prompts rendered with your own design system on the same screen the user is already working in.
Let agents read and write application state, call your frontend functions, and pause for human approval before sensitive actions are executed.

Install once and pull open-weight models by name; Ollama handles weights, quantization and versioning for you.
A built-in server exposes a straightforward REST API, so scripts, editors and agents can talk to local models with minimal setup.
Route requests to hosted open models when your laptop cannot hold the checkpoint you need, with per-token pricing and concurrency tiers.
Access families such as Llama, Qwen, DeepSeek, Gemma, Mistral and gpt-oss from a single interface.
SpecialistCloud API gateway providing instant access to thousands of models, trading local hardware privacy for cloud compute.
