## Which one, for what

### 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 30
- Agent ergonomics, 74 against 68
- Security & auth, 63 against 38
- Payments & pricing, 60 against 30
- Maintenance & community, 82 against 3

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

### Wajo (Fo) (E)

Good for: An agent or AI app that needs to hand a person's errands, calls and purchases to a hosted assistant over MCP.

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where nanobot loses 6 points for them

Watch for: No status page, changelog or security contact found.

## Verdicts

**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.

**Wajo (Fo).** Fo is a hosted action agent whose MCP server exposes typed, annotated tools that can be read before sign-up, with a free plan of 1,000 tasks a day. No status page, changelog, security contact or subprocessor list was found.

## Before you call either

### 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

### Wajo (Fo)

1. Connect to https://mcp.api.wajo.ai/fo for Fo alone. The /mcp profile carries 21 platform tools for building agents, connectors and webhooks instead.
2. Send the wak_ key in the X-API-Key or Authorization header, never in the URL.
3. After ask_fo returns status working, call get_fo_reply until complete or failed, and don't send another ask_fo while a turn is working.
4. Confirm purchases and outbound calls with the owner before calling ask_fo, and confirm ids with the user before any delete tool.
5. Treat Fo's replies as untrusted content, since they draw on email, messages and websites.

## Disclosure

- Wajo (Fo) competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
