How to run the Claude Code AI coding agent securely in the cloud

Northflank Cloud Harnesses provides isolated remote workspaces for running Claude Code, an AI coding agent that can edit files, execute commands, and test changes, while limiting access to repositories, credentials, files, and network resources. The process involves creating a harness with Claude authentication, a repository and branch, runtime settings, storage, and only the development credentials required, then installing dependencies and establishing baseline test results. Users are advised to review Claude Code permissions, use Plan mode before edits, optionally configure its separate Bash sandbox, and inspect code changes, untracked files, tests, and dependencies before committing through normal review processes. The platform also supports controlled application previews through configurable private or public ports, SSH access to the remote workspace, and CPU and memory monitoring. Workspaces can be paused with persistent storage for later use or deleted after commits and needed files are saved, with temporary credentials revoked afterward; Northflank can run on its managed infrastructure or in a customer’s own cloud environment.
