DigitalOcean Harness Runtime Referencepublic
Last verified 21 Sep 2026
DigitalOcean Harness Runtime combines the functionality of a lightweight microVM, built-in tools like chromium and a coding sandbox needed by agents to do work. The product offers rich lifecycle APIs that persist conversational history and working state across sessions, with pause/resume/fork semantics so that developers can control costs and adapt workflows to the nonlinear quirks of agentic work. See What You Can Build for example use cases.
Additional Tools for Harness Runtime
The DigitalOcean API
The DigitalOcean API lets you manage resources programmatically with standard HTTP requests. All actions available in the control panel are also available through the API.
Harness Runtime session and configuration endpoints are under /v2/agents/*. See the API documentation for authentication and request format.
The DigitalOcean Command Line Client, doctl
doctl is the command-line interface for the DigitalOcean API. It supports most of the same actions available in the API and DigitalOcean Control Panel.
Harness Runtime commands live under doctl harness-runtime. See the doctl documentation or use doctl harness-runtime --help for more information.
