## 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:
- Schema & documentation, 80 against 72
- Transparency & trust, 69 against 47

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Vibe-Trading loses 4 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

### Vibe-Trading (B)

Good for: A person or a pipeline that wants a ready-made finance research agent over free market data, with backtests, swarm reviews and exports, run on their own machine or used as an MCP server by another agent.

Ahead on:
- Reliability, 63 against 30
- Agent ergonomics, 67 against 62
- Payments & pricing, 60 against 20
- Maintenance & community, 82 against 63

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Free to start without a card
- Open source

Watch for: Three advisories published 2 October 2026 cover 0.1.0 to 0.1.6, two critical, among them unauthenticated API access with an RCE chain

## 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.

**Vibe-Trading.** Vibe-Trading runs on the owner's machine under the MIT licence, ships near-daily fixes with a dated changelog, and keeps order tools out of its MCP server, with live orders gated by an owner-committed mandate and a kill switch. Three advisories, two critical, covered versions before 0.1.7, and the local CLI runs shell commands without asking.

## 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

### Vibe-Trading

1. Run 0.1.7 or later. Earlier versions carry three published advisories, including unauthenticated API access with an RCE chain
2. Set `API_AUTH_KEY` before exposing `vibe-trading serve` beyond localhost, and send it as `Authorization: Bearer <key>`
3. Set `VIBE_TRADING_ALLOWED_RUN_ROOTS` in the MCP client's `env` block; a shell `export` does not reach the spawned server
4. Use `vibe-trading run -p "..." --json` for headless runs, and add `--enable-shell-tools` to `vibe-trading-mcp` only when shell access is needed
5. Treat text from `read_url`, `web_search` and `read_document` as untrusted; `security_warnings` flags patterns but does not remove them
