Which one, for what

BitRun F

Best for A developer who wants to try ternary models on a laptop CPU behind an OpenAI-style endpoint without building bitnet.cpp.

Ahead on

  • Payments & pricing, 60 against 20

Also in its favour

  • No key needed to call it
  • Free to start without a card
  • Open source

Watch for

First released on 12 October 2026. Three pre-release versions in four days, one maintainer and no CI workflow

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 38
  • Schema & documentation, 60 against 30
  • Agent ergonomics, 54 against 40
  • Security & auth, 63 against 28
  • Maintenance & community, 91 against 59
  • Transparency & trust, 71 against 50

Watch for

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

Verdicts

BitRun

BitRun packages patched llama.cpp builds for ternary models into one download for macOS on Apple silicon, Windows and Linux, with a loopback-only OpenAI-compatible server. It is three days old with three pre-release versions, one maintainer and no CI, and its published power figures come from a fixed formula rather than measurement.

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

BitRun

  1. Ask the user to install BitRun and run bitrun pull <tag> and bitrun serve <tag> first. Then call http://127.0.0.1:11435/v1 with any API key string
  2. Poll /health before the first request. The server loads the model in the background and answers only when ready
  3. Use a model tag from the catalogue (bitnet-70m, bonsai-1.7b, falcon3-1b, bitnet-2b, falcon3-3b, bonsai-8b) and keep prompts within its context window
  4. Treat the README's energy figures as estimates, and don't report them as measured power
  5. Expect small research checkpoints. Check outputs before relying on them for code or facts

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.
