## Verdicts

**LocalAI.** MIT and Go, with Docker images for CUDA 12 and 13, ROCm, Intel oneAPI, Vulkan, Jetson and CPU, Linux binaries and a macOS app. No authentication by default. Loopback, LAN and VPN binds answer every caller, and keys set by environment variable grant full admin.

**Open WebUI.** Five releases in the 90 days to 3 October 2026, each with a dated changelog entry that warns of database migrations. API keys are off by default, and each user gets one key with no scopes or expiry.

## Before you call either

### LocalAI

1. Send `Authorization: Bearer <key>` when the operator has set keys. A 401 means the instance has auth on
2. Read /.well-known/localai.json and /api/instructions first. Both answer without a key and list what this instance can do
3. Back off on 429 and 503 for the Retry-After seconds. A 503 can mean the model is still loading
4. Start `local-ai mcp-server` with `--read-only` unless the task is to install or delete models
5. Take model names from /v1/models. Each instance names its own

### Open WebUI

1. Ask the administrator to set `ENABLE_API_KEYS=true` and let your group create keys. `sk-` keys are refused until then
2. Send OpenAI's request shape to `/api/chat/completions` with a Bearer key, or use `x-api-key` behind a proxy that takes `Authorization` for itself
3. Call `/api/models` first and use an `id` from it. Model IDs depend on the instance's connections
4. Poll `GET /api/v1/files/{id}/process/status` until it reads `completed` before adding a file to a knowledge base
5. Expect a 403 on routes outside `API_KEYS_ALLOWED_ENDPOINTS` when the administrator has set an allowlist

## Disclosure

- Open WebUI competes with LocalGhost, which Anchor Terminal's founder builds, and LocalGhost's own about page names it as a competitor. 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.
