Features
Long running, auto-scaling sandboxes
Deploy agents that run for hours or days in isolated sandboxes. Infrastructure scales on demand so you can focus on building, not babysitting.
MCP gateway
Skip the integration spaghetti. Our MCP gateway gives agents access to any tool or API while you control permissions from a single dashboard.
One click deploy
One click. Your Claude agent is live. Castari manages provisioning, versioning, and execution behind the scenes.
Agent observability
Full visibility into every agent decision. Trace tool calls, inspect outputs, and debug in real time—not after something breaks in production.
Model router
Use any model with the Claude Agent SDK—OpenAI, xAI, GLM, and more. Keep your agent code, swap the model. No rewrites required.

FAQs
What is Castari?
Castari is a deployment platform for Claude Agent SDK agents. Import your project, run cast deploy, and your agent is live with auto-scaling, logging, and observability built in.
Do I need to modify my code to use Castari?
No. Castari works with standard Claude Agent SDK code without modification. You keep full ownership of your codebase with zero vendor lock-in—if you ever want to self-host, your agents will run anywhere. We simply provide the infrastructure layer.
Why use Castari instead of deploying myself?
Deploying agents yourself means managing containers, configuring secure environments, handling scaling logic, and monitoring execution. Castari handles all of this out of the box with production-grade infrastructure and no DevOps overhead.
How do you handle security and isolation?
Every agent runs in an isolated sandbox environment. We use a variety of sandbox providers to ensure security and performance. The ability to select your own sandbox provider is coming soon.
How much does Castari cost?
Castari is free during our private beta. When we launch publicly, we'll use usage-based pricing—you'll pay only for the compute your agents use, not per seat or per agent.
Which AI models does Castari support?
Castari supports any model with the Claude Agent SDK—not just Claude. Use OpenAI, xAI, open source models, or any provider you prefer. Your agent code stays the same.
How do I get started with Castari?
Getting started takes less than 5 minutes. Install the CLI with npm install -g @castari/cli, authenticate with cast login, and deploy your Claude Agent SDK agent using cast deploy. Your agent will immediately be accessible via REST API or our SDK.
