Authentication is off by default, the repository has no security policy, and the docs tell WebSocket clients to pass the key in the URL.\n\n**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.\n\n## Before you call either\n\n### Lemonade\n\n1. Call `lemonade_list_models` (or `GET /v1/models`) before naming a model. A wrong name with `allow_download: true` can start a multi-gigabyte download\n2. Send `Authorization: Bearer \u003ckey\u003e` when the operator has set `LEMONADE_API_KEY`. `/internal/*` needs the admin key when one is set\n3. Use `POST /v1/chat/completions` for streamed tokens, embeddings and speech. The MCP endpoint ignores `stream` and has no embeddings or text-to-speech tool\n4. Pass `output_dir` to `lemonade_generate_image` and `lemonade_omni` to get file paths in place of inline base64. Writes stay inside the MCP media sandbox\n5. Read `GET /v1/docs` on the running server for the reference that matches its version. Weekly releases change behaviour\n\n### Open WebUI\n\n1. Ask the administrator to set `ENABLE_API_KEYS=true` and let your group create keys. `sk-` keys are refused until then\n2. 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\n3. Call `/api/models` first and use an `id` from it. Model IDs depend on the instance's connections\n4. Poll `GET /api/v1/files/{id}/process/status` until it reads `completed` before adding a file to a knowledge base\n5. Expect a 403 on routes outside `API_KEYS_ALLOWED_ENDPOINTS` when the administrator has set an allowlist\n\n## Questions\n\n### Which is better for AI agents, Lemonade or Open WebUI?\n\nLemonade scores 63.8 (B) on agent readiness against Open WebUI's 51.8 (D), and leads in 4 of 7 scored categories. Open WebUI leads on security \u0026 auth, maintenance \u0026 community and transparency \u0026 trust.\n\n### Can an agent call Lemonade and Open WebUI without installing anything?\n\nNo hosted endpoint is listed for Lemonade. No hosted endpoint is listed for Open WebUI.\n\n### Are Lemonade and Open WebUI open source?\n\nLemonade is open source (Apache 2.0. Each backend (llama.cpp, whisper.cpp, stable-diffusion.cpp, FastFlowLM and others) is downloaded separately under its own licence).
