About Cedar
Summary
Cedar builds an open-source React framework that lets developers embed AI agents directly into their application's frontend, moving user interaction beyond a chat window. Product teams use it to add voice interfaces, human-in-the-loop controls, and real-time Slack handoff to their existing apps. It replaces custom glue code and reduces reliance on customer success managers to walk users through complex workflows.
Go-to-market
B2B software teams adopt Cedar by integrating the open-source framework into their existing React apps, with the open-source distribution serving as the primary acquisition channel.
From the Y Combinator listing
The open source copilot for any app
An open-source React framework for building the next generation of AI native applications. With Cedar, connect your agent to your frontend in ways that go beyond the chat. Jesse worked at Intuit, writing software for TurboTax designed for customers of all tech literacy levels. Isabelle worked at Figma and Notion, learning about the struggles of getting users to effectively use powerful yet complex products as well as GTM strategies to reach them. With Cedar, user interaction is not constrained to a chat window. We offer tools making it easy to build a voice-enabled experience, add human-in-the-loop for agent observability, and deliver realtime analytics + human handoff when needed to Slack. Reduce back and forth with CSM, decrease time to completion for important user tasks, and give your users a delightful experience using Cedar :-D
