Is Cedar-OS right for you?

How we're different

Craft & Extensibility

Architecture

Cedar-OS is built for the most ambitious AI-native applications - every single internal function can be overridden in one line
Cedar components are downloaded Shadcn-style - you own all the code and can customize it however you want.

Simplicity

Want a working chat? Import <CedarFloatingChat/> and it just works with streaming, tool calls, and agentic actions.

Breaking out of chat

Text is cognitively demanding to read and write. Much like the GUI broke out of the terminal, AI interactions will break out of chat.

Built from Production Experience
