# Run Agent Frameworks on DigitalOcean Harness Runtime (public)

Generated on 13 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](https://docs.digitalocean.com/products/managed-agents/agent-harness-runtime/details/what-you-can-build/index.html.md) for example use cases.

[How to Run a LangGraph Agent on DigitalOcean Harness Runtime](https://docs.digitalocean.com/products/managed-agents/agent-harness-runtime/how-to/run-langgraph-agent/index.html.md): Package a LangGraph repository, configure model credentials, and deploy your graph on Harness Runtime.

[How to Run a CrewAI Agent on DigitalOcean Harness Runtime](https://docs.digitalocean.com/products/managed-agents/agent-harness-runtime/how-to/run-crewai-agent/index.html.md): Package a CrewAI repository, declare kickoff inputs, connect a model and Action Gateway tools, and deploy your crew on DigitalOcean Harness Runtime.

[How to Run a Hermes Agent on DigitalOcean Harness Runtime](https://docs.digitalocean.com/products/managed-agents/agent-harness-runtime/how-to/run-hermes-agent/index.html.md): Run the Hermes gateway as a long-lived agent inside a Harness Runtime sandbox and reach its admin dashboard from your machine.

[How to Run an OpenHands Agent on DigitalOcean Harness Runtime](https://docs.digitalocean.com/products/managed-agents/agent-harness-runtime/how-to/run-openhands-agent/index.html.md): Run the OpenHands Agent Server in a Harness Runtime sandbox, create agents from OpenHands Agent Canvas or the DigitalOcean API, and connect a model.

[How to Run an OpenAI Agents API Session](https://docs.digitalocean.com/products/managed-agents/agent-harness-runtime/how-to/run-openai-agents-api-session/index.html.md): Connect an OpenAI Agents API session to a DigitalOcean Harness Runtime sandbox using the CLI, PyDo, or an OpenAI webhook controller.
