Anthropic launches public beta for self-hosted Claude Code environments

Anthropic has released a public beta for self-hosted environments, allowing enterprises to run Claude Code sessions on their own infrastructure rather than Anthropic's hosted servers. This setup enables sessions to operate within a company's network, providing direct access to internal services, databases, and security controls while keeping source code and build artifacts on-premises.

Architecture and Modes

The system relies on runners, which are long-running processes that execute individual sessions. Organizations can deploy runners in two modes:

• Fixed: A set number of runners are maintained, with sessions distributed across them.
• On-demand: An orchestrator spins up runners as sessions are queued and terminates them when idle, optimizing resource usage.

Each session runs in an isolated checkout, ensuring that work from different users or accounts remains separate. While the execution environment is local, the conversation history—including prompts, responses, and tool results—is still sent to Anthropic for model inference.

Availability and Requirements

This feature is currently in public beta and is available only to organizations on Claude Team and Enterprise plans. It is disabled by default and is not supported for organizations using Zero Data Retention (ZDR). Anthropic recommends that platform or DevOps teams manage the setup, including maintaining runner images and orchestrators, as the complexity of self-hosting requires dedicated engineering resources.
