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.
Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
