## Which one, for what

### OpenCode (B)

Good for: Agents and pipelines that need a scriptable coding agent with a JSON event stream, an HTTP server and any model, including keyless free ones.

Ahead on:
- Reliability, 72 against 63
- Schema & documentation, 88 against 72
- Agent ergonomics, 79 against 67
- Transparency & trust, 67 against 47

Watch for: Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox

### 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:
- Security & auth, 70 against 60

Also in its favour:
- Runs on your own machine

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

**OpenCode.** Runs with no key or account on free OpenCode Zen models. Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox.

**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

### OpenCode

1. Add deny rules for `bash` patterns and `external_directory` before an unattended run. Most tools default to allow
2. Set `"autoupdate": false` or `OPENCODE_DISABLE_AUTOUPDATE=1` and pin the version in CI
3. Configure a provider key. With none, prompts go to free Zen models that may train on them
4. Set `OPENCODE_SERVER_PASSWORD` before `opencode serve`. Without it the server runs unauthenticated
5. Install `opencode-ai` for the 1.x server API and SDK. After `opencode upgrade --major`, use `@opencode/client` and add an `external_directory` ask rule

### 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
