## Which one, for what

### Devin (C)

Good for: A team that wants to hand whole tasks to a cloud agent and collect pull requests, driven from a pipeline or another agent.

Ahead on:
- Security & auth, 72 against 66

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where OpenHands loses 5 points for them

Watch for: www.devinstatus.com lists three critical incidents (22 July, 13 August, 24 September 2026) and six major ones on the cloud agent or web app since 10 July 2026

### OpenHands (BB)

Good for: Teams that want to self-host a coding agent with a web UI, per-conversation Docker sandboxes and scheduled or webhook automations, or embed the agent through a Python SDK and REST API.

Ahead on:
- Reliability, 83 against 30
- Schema & documentation, 87 against 80
- Agent ergonomics, 78 against 62
- Payments & pricing, 60 against 20
- Maintenance & community, 85 against 63

Also in its favour:
- Agent-ready, a grade of BB or better
- Open source

Watch for: Confirmation mode is off by default in Agent Canvas, and the npm install gives the agent the host's whole filesystem

## Verdicts

**Devin.** The v3 API is well specified, with a public OpenAPI 3.1 file covering 239 operations, problem+json errors, cursor pagination and service-user keys tied to roles. The status page records three critical and several major incidents on the cloud agent between 22 July and 24 September 2026, and no rate limit figures or retry guidance were found in the reviewed documentation.

**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.

## Before you call either

### Devin

1. Use a `cog_` service-user key with the Member role. Legacy `apk_` keys fail against v3 and the MCP server with 401 or 403
2. Set `max_acu_limit` on every session you create. Usage is metered by the work done and has no published unit rate
3. Session creation is not idempotent in v3. After a timeout, list sessions by tag before creating again
4. Enterprise keys and personal access tokens must send `X-Org-Id` to the MCP server. Organisation-scoped keys resolve it automatically
5. Create scheduled work as an automation. POST to the schedules endpoint returns 403 for migrated organisations since 24 September 2026

### 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
