Crush vs OpenHands

Crush

Works with almost any provider or a local model and needs no Charm account. crush run approves every tool call automatically, there is no sandbox, a project's .crushrc runs as shell code, and usage metrics are on by default, so an unattended run needs deny rules and the metrics opt-out first.

OpenHands

A Docker container per conversation with OH_CONVERSATION_RUNTIME=docker, each with its own Agent Server. Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem.

Crush

1. Add permissions deny rules or a PreToolUse hook before crush run. It approves every permission request in its session
2. Read .crushrc, crushrc and crush.json in a cloned repository before running Crush there. They execute as shell code at startup
3. Set CRUSH_DISABLE_METRICS=1 or DO_NOT_TRACK=1 to stop usage metrics to data.charm.land
4. Wrap crush run in your own timeout. It has no turn, time or cost limit flag
5. Configure a provider by environment variable or crushrc first. With none, crush run exits with an error asking for interactive setup

OpenHands

1. Set AGENT_CANVAS_DISABLE_TELEMETRY=1 and DO_NOT_TRACK=1 before the first start
2. Start Canvas with OH_CONVERSATION_RUNTIME=docker or use the Docker image. The npm install runs the agent on the host
3. Turn on confirmation mode with a risk threshold. Canvas starts with it off
4. Use the SDK or the Agent Server API for headless runs. The openhands --headless CLI is no longer maintained
5. Set filter_tools_regex on the agent to keep unneeded MCP tool definitions out of the context
