## Which one, for what

### Haven (F)

Good for: A consumer assistant for one person who wants to phone, text or email it and have it remember them.

Also in its favour:
- No incidents deducted, where nanobot loses 6 points for them

Watch for: No approval setting or list of actions that need confirmation was found on the public pages. The terms say it sends emails, SMS and calls following the user's instructions.

### nanobot (B)

Good for: A technical owner who wants an assistant on their own machine across many chat apps, with file-based memory and a free choice of model.

Ahead on:
- Reliability, 70 against 35
- Schema & documentation, 77 against 4
- Agent ergonomics, 74 against 6
- Security & auth, 63 against 13
- Payments & pricing, 60 against 30
- Maintenance & community, 82 against 35

Also in its favour:
- No key needed to call it
- Open source

Watch for: No per-action approval was found in the docs or source. The agent sends messages, runs shell commands and edits files without asking

## Verdicts

**Haven.** Haven answers by phone call, text, email and app, is free in beta with no card, and publishes a status page with dated incidents. No public page read says which actions need approval, which accounts it connects or how their tokens are kept, and it names no model provider or sub-processor.

**nanobot.** nanobot runs on the owner's machine under the MIT licence, with no telemetry found in its source and memory kept as files the owner can read and restore. No per-action approval step was found, and the shell sandbox and workspace restriction are off by default. Five security advisories were published between March and September 2026, all with fixes.

## Before you call either

### Haven

1. Haven has no documented API or MCP server. An outside agent can reach it only through the owner's channels (call, SMS, email, app).
2. Do not assume an approval step before Haven sends mail, texts or calls. None is documented on the public pages.
3. Email Haven sends to other people names Hello Haven as sender and says it was sent on the user's behalf, per the terms.
4. Chat messages, history, profile context and uploaded files go to third-party AI model providers that the vendor does not name.
5. Check status.hellohaven.ai before relying on phone or voice. All four published incidents affected those channels.

### nanobot

1. Set `tools.restrictToWorkspace` to true and `tools.exec.sandbox` to `bwrap` or `seatbelt` before giving it real accounts. Both are off by default
2. Run 0.3.0 or later. Earlier versions carry the published SSRF flaw in web fetch (GHSA-vc5v-6vwm-wf9m)
3. Keep `allowFrom` narrow on every channel and never set `["*"]` on Email, which has no pairing
4. Write secrets as `${VAR}` references in `~/.nanobot/config.json`. Plain values are stored in clear text
5. Use `nanobot -m "..."` for a one-shot run, and keep `nanobot gateway` running for channels, schedules and heartbeat
