Verdicts
GAIA
GAIA's source is public, so its approval gate, memory store and token handling can be read. Three approval modes and per-tool overrides exist, but the default mode in the source runs every action unasked, which the privacy policy and release notes do not say. Pro costs $30 a month and self-hosting is limited to noncommercial use.
Zapia
Zapia is a personal assistant app for iOS, Android and the web with a free plan that isn't a trial, weekly iOS releases and explicit confirmation before anything that writes. No outside agent can call it, and no status page, security contact or hosting location was found.
Before you call either
GAIA
- Set Settings > Approvals to Always ask or Auto before connecting mail. The default in the source runs every action, including send and delete, without asking.
- Expect no public API on the hosted service. The backend turns off its OpenAPI document in production, so reach GAIA through its apps, bots or CLI.
- Check the plan before relying on the hosted service. The README and docs describe a Free plan, and the pricing page says GAIA is a paid product.
- For self-hosting, prepare Docker, Node.js 20, a WorkOS account and a model key first, and confirm the use is noncommercial under the licence.
- Add outside tools as MCP servers by URL on the Integrations page. GAIA asks before adding a server in every approval mode.
Zapia
- Don't plan to call Zapia from another agent. It answers only in its own app and on the web, and the terms forbid unauthorised automated access.
- Tell the owner that Pro and Ultra trials become paid after 7 days unless cancelled in the app store.

Disclosure
Zapia 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.
