Introducing

Freesail

Agent-driven UI SDK

What is Freesail?

Freesail is an Agent-driven UI SDK that lets your AI agents dynamically drive rich user interfaces — without writing any code.

Say goodbye to walls of text. Give AI agents a safe, structured channel to render rich UI components that capture user attention, in real-time.

3 Node Architecture

Freesail is built on a three-node architecture that separates control logic from UI and data streaming.

AI logic, validation layer, and presentation layer are independently scalable and maintainable.

Agent

The Agent is the intelligence layer of Freesail. The three-node architecture allows the Agent to focus only on logic and decision-making, leaving the data streaming to the Gateway and rendering to the front-end. It is a clean separation that allows for scalable, more adaptable interfaces.

Gateway

The Freesail Gateway acts as a bridge and translates messages between the agent and the frontend. The gateway queues the response from the front-end and notifies the agent to take further action. This layer is crucial for maintaining consistency and reliability across the system.

Front-end

The Frontend is responsible for rendering the UI. It maintains the local data model, handles user interactions, and manages automatic retries if the network connection drops. This ensures a smooth and responsive user experience, regardless of network conditions.
