DigitalOcean Harness Runtimepublic
Generated on 14 Oct 2026
DigitalOcean Harness Runtime provides managed, hardware-isolated microVM sandboxes with built-in tools such as Chromium to run harnesses and execute arbitrary code. Rich lifecycle APIs preserve conversational history and working state across sessions, letting you pause, resume, and fork work to control costs and adapt to the nonlinear nature of agentic workflows. Scale complete agents such as Claude Code or use sandboxes independently for code execution, all through the same service. See What You Can Build for example use cases.
Quickstart
Start a Codex CLI agent in an isolated DigitalOcean sandbox with a single doctl command.
Examples
Worked examples of Harness Runtime, each with a complete environment spec and the commands to run it, covering coding, marketing, document review, incident response, and multi-tenant agent products.
How-Tos
Task-focused guides for deploying agents, managing sessions, permissions, files, and tools.
Reference
Environment spec reference and links to doctl resources for Harness Runtime.
Concepts

Latest Updates
12 October 2026
-
DigitalOcean Harness Runtime now supports OpenHands agents. Run the OpenHands Agent Server in an isolated sandbox, create agents from OpenHands Agent Canvas or the DigitalOcean API, and connect a model such as one from DigitalOcean Serverless Inference. To set up an agent, see How to Run an OpenHands Agent on DigitalOcean Harness Runtime.

DigitalOcean Signals is now available in public preview for Harness Runtime agents and Serverless Inference. Signals detects behavioral signals in conversations, such as a user asking for a human, a failed tool call, or an execution loop, so you can find the conversations that went wrong without reading every transcript. Signals collects data only after you opt in. See Use Signals with Harness Runtime and Use Signals with Serverless Inference.

DigitalOcean Harness Runtime now supports CrewAI agents. Package a CrewAI repository, declare kickoff inputs, connect a model and Action Gateway tools, and deploy your crew in an isolated sandbox. For more information, see How to Run a CrewAI Agent on DigitalOcean Harness Runtime.
-
Harness Runtime Bring-Your-Own-Template (BYOT) registration now requires a recommended base template (
codex-base,opencode-base,claude-code-base,hermes-base, orlanggraph-base). Recommended bases provide stronger isolation for custom templates than previously supported bases (coding-codex,coding-opencode,coding-claude-code,coding-hermes, andlanggraph). The legacy bases remain available for existing custom templates and for rebuilds of those templates. Support for them in BYOT will be removed in a future release. Sessions that use the legacy base templates as adapter default templates continue to work as usual. For more information, see How to Use a Custom Sandbox Template (BYOT).
