What is Castari?

Castari is a deployment platform specifically designed for Claude Agent SDK agents, offering a streamlined process for building, deploying, and scaling AI agents. It allows developers to deploy agents to isolated cloud sandboxes with a single command, ensuring high security with features like network policies, ephemeral environments, and end-to-end encryption. The platform supports unlimited customization, allowing users to bring their own models, tools, and workflows, and provides full control over runtime configuration. Castari also offers infinite scalability, automatically adjusting infrastructure to meet demand without capacity planning or cold starts. Key features include auto-scaling sandboxes, an MCP gateway for connecting to external services, a model router for optimizing requests across AI providers, and comprehensive agent observability for debugging and iteration.

FAQs

What is the Claude Agent SDK and why is it central to Castari?

The Claude Agent SDK is a framework for building AI agents, and Castari is specifically designed as its deployment platform. It allows users to deploy agents built with this SDK without modifying their code, providing infrastructure for scaling, security, and observability.

How does Castari ensure the security and isolation of deployed AI agents?

Castari runs every agent in a fully isolated sandbox environment with zero shared state. It implements network policies, ephemeral environments, and end-to-end encryption to protect data and users, with the ability to select sandbox providers coming soon.

What is the pricing model for Castari after the public beta phase?

Castari is currently free during its public beta. Upon general availability, it will transition to a usage-based pricing model, meaning users will only pay for the compute resources their agents consume, rather than per seat or per agent.

Can I use AI models other than Claude with Castari?

Yes, Castari supports any model compatible with the Claude Agent SDK, not exclusively Claude. This includes models from OpenAI, xAI, open-source options, or any other provider, allowing your agent code to remain consistent.
