Verdicts

Del

Del is a hosted texting assistant and task workspace across iMessage, WhatsApp, Telegram, SMS, Discord and Slack, with a near-daily public changelog and a card-free 14-day trial. No outside agent can call it, no status page or security contact was found, and recent updates let some email actions skip approval.

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.

Before you call either

Del

  1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace.
  2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro.

GAIA

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Add outside tools as MCP servers by URL on the Integrations page. GAIA asks before adding a server in every approval mode.

Other comparisons with Del or GAIA

Disclosure

Del 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.

Machine-readable

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
