Verdicts
HyperQwen
HyperQwen packages a patched vLLM 0.32.0 and requantised Qwen3.8-27B weights into one container with tool calling preset and a loopback bind when no key is set. It runs one model family, its speed figures come from one RTX 3090, and it has no versioned releases, changelog or security policy.
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
HyperQwen
- Call http://127.0.0.1:18020/v1 with model
qwen3.8-27band theVLLM_API_KEYvalue, or any string if no key was set - Poll
/healthbefore the first request. A first start downloads and prepares the model and compiles kernels, which can take over 30 minutes - Declare the context window your setup uses (65,536 by default, 131,072 for
CTX=long, 245,760 forCTX=huge) so the client doesn't truncate - Ask the owner to set
VLLM_API_KEYbefore settingBIND=0.0.0.0, and to front the port with a proxy that allowlists routes - Treat the README's tokens-per-second figures as the project's measurements on one RTX 3090 at 250 W
Open WebUI
- Ask the administrator to set
ENABLE_API_KEYS=trueand let your group create keys.sk-keys are refused until then - Send OpenAI's request shape to
/api/chat/completionswith a Bearer key, or usex-api-keybehind a proxy that takesAuthorizationfor itself - Call
/api/modelsfirst and use anidfrom it. Model IDs depend on the instance's connections - Poll
GET /api/v1/files/{id}/process/statusuntil it readscompletedbefore adding a file to a knowledge base - Expect a 403 on routes outside
API_KEYS_ALLOWED_ENDPOINTSwhen 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.
