Which one, for what

HyperQwen C

Best for An operator with one 24 GB NVIDIA card who wants Qwen3.8-27B behind an OpenAI-compatible endpoint for a coding or tool-calling agent, with long context.

Ahead on

  • Agent ergonomics, 65 against 54
  • Payments & pricing, 60 against 20

Also in its favour

  • No key needed to call it
  • Free to start without a card
  • Open source
  • No incidents deducted, where Open WebUI loses 8 points for them

Watch for

Serves Qwen3.8-27B and checkpoints derived from it only. Other models are on the roadmap

Open WebUI D

Best for A household or team that wants one chat interface over local and hosted models, with shared knowledge bases, memories, tools and access control, on their own server.

Ahead on

  • Reliability, 68 against 59
  • Security & auth, 63 against 41
  • Maintenance & community, 91 against 68
  • Transparency & trust, 73 against 55

Watch for

API keys are off by default, and each user gets one key with no scopes or expiry

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

  1. Call http://127.0.0.1:18020/v1 with model qwen3.8-27b and the VLLM_API_KEY value, or any string if no key was set
  2. Poll /health before the first request. A first start downloads and prepares the model and compiles kernels, which can take over 30 minutes
  3. Declare the context window your setup uses (65,536 by default, 131,072 for CTX=long, 245,760 for CTX=huge) so the client doesn't truncate
  4. Ask the owner to set VLLM_API_KEY before setting BIND=0.0.0.0, and to front the port with a proxy that allowlists routes
  5. Treat the README's tokens-per-second figures as the project's measurements on one RTX 3090 at 250 W

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.

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.
