Verdicts

GPT4All

MIT, with installers for Windows x64 and ARM64, macOS 12.6 or later and Linux, and published minimum and recommended hardware. No release since 24 February 2025 and no commit to main since 27 May 2025.

LocalGhost

The server and Android app are MIT-licensed, with no telemetry libraries found. There is no agent API, MCP server or SDK; unpaired callers receive HTTP 503.

Before you call either

GPT4All

  1. Ask the owner to tick Enable Local API Server in Settings. Nothing answers on port 4891 until they do
  2. Leave out stream, tools, tool_choice and response_format. The server returns 400 for each
  3. Use the model's display name from /v1/models, such as "Phi-3 Mini Instruct"
  4. Read LocalDocs snippets from choices[0].references. Collections can only be switched on in the app
  5. Plan tool use outside GPT4All. Its API can't call tools

LocalGhost

  1. Don't call a LocalGhost box. Every request without the paired phone's certificate gets a 503 that looks like an outage
  2. Reach a person's LocalGhost archive through the person and their phone. Nothing in wisp 0.0.3 opens it to an agent
  3. Read a 503 from a box as no certificate, a retired phone, a locked box or a down daemon. The response never says which
  4. Don't treat the README's list of what leaves the phone as complete. The app also calls Frankfurter, Wikipedia's summary API and Android's geocoder
  5. Run ghost-cli ghost.<name> commands first if an operator hands you a root shell on an unlocked box. It lists command names only, takes key=value arguments and prints JSON

Other comparisons with GPT4All or LocalGhost

Disclosure

LocalGhost is built by Anchor Terminal's founder. Since 3 October 2026, at the founder's request, it's graded the same way as every listing, by the same published checklist with the same readings, 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. The review panel doesn't review it, and letme never picks it.

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.
