dsh-owui-chat2api

An adapter that exposes the models in your Open WebUI as a standard OpenAI-compatible /v1 API for DSH (DSH Desktop or the stock web UI), plus a usage dashboard that lives inside DSH.

It bundles chat2api, runs it as a local reverse proxy, and adds a control panel to the DSH web shell:

DeepSeek Harness (or any OpenAI-compatible client)
        │        standard /v1 API → http://127.0.0.1:8000
        ▼
   dsh-owui-chat2api    (local reverse proxy, keeps its own login)
        ▼
   your Open WebUI      (browser sign-in once, session reused afterwards)

Features ✨

• ▶️ Start / stop the proxy from the panel
• 🩺 Environment check: is Python available, are the dependencies installed?
• ⚙️ Configure your Open WebUI URL, host and port
• 📊 Usage dashboard: today / yesterday / month / total, ranked per model with colorful share bars — plus a manual price table (per 1M tokens, cached tokens priced separately) that turns the stats into a cost estimate
• 🧠 One-click model and reasoning-level sync (see Reasoning effort)
• 📜 Process log with error highlighting, follow mode and copy
• 🎨 Color-coded sections with inline Tabler icons that follow the DSH theme (dark / light), zero external requests

Install 📦

Pick one of three ways: A is a single command, B needs no git, C lets your DSH assistant do the whole thing.

⚡ Option A — one command (recommended)

The dsh CLI ships a plugin manager. One command installs the plugin and registers it in your profile (dependencies + bundles). Pick the profile that matches your setup — desktop for DSH Desktop, web for the stock web UI:

dsh plugin --profile desktop add github:Wecury/dsh-owui-chat2api#v0.8.0
dsh plugin --profile web add github:Wecury/dsh-owui-chat2api#v0.8.0

• #v0.8.0 pins the release tag — use the version you want (omit it to follow main).
• Requires git on PATH (pnpm clones the repo). Behind a proxy? Export http_proxy / https_proxy first.
• Restart DSH when it finishes. Later updates (same --profile as install): dsh plugin --profile <desktop|web> update dsh-owui-chat2api.

📦 Option B — from the release tarball (no git needed)

1. From Releases → Assets, download dsh-owui-chat2api-<version>.tgz. (The Source code (zip) button is the development tree — for contributing, not for installing.)

2. Unpack it into the plugins folder. The tarball extracts to a package/ directory — move and rename it (tar ships with Windows 10+):

   tar -xzf dsh-owui-chat2api-0.8.0.tgz
   Move-Item package "$env:USERPROFILE\.dsh\plugins\dsh-owui-chat2api-0.8.0"
   

3. Register it in %USERPROFILE%\.dsh\profiles\<desktop|web>\package.json (desktop for DSH Desktop, web for the stock web UI):

   "dependencies": {
     "dsh-owui-chat2api": "link:%USERPROFILE%\\.dsh\\plugins\\dsh-owui-chat2api-0.8.0"
   },
   "dsh": { "profile": { "bundles": [ /* ... */ "dsh-owui-chat2api" ] } }
   

   Match the folder name to the version you downloaded.

🤖 Option C — let your DSH install it

Paste this to your DSH assistant and it will do the rest:

请帮我安装 DSH 插件 dsh-owui-chat2api(GitHub 仓库 Wecury/dsh-owui-chat2api)。

步骤:
1. 执行:dsh plugin --profile desktop add github:Wecury/dsh-owui-chat2api#v0.8.0
   (用原版 web 界面就把 --profile desktop 换成 --profile web。需要本机有 git。
   如果 dsh plugin 不可用,改用手动方式:从仓库 Releases 的 Assets 下载
   dsh-owui-chat2api-<版本>.tgz,解压得到 package/ 文件夹,移动并改名为
   %USERPROFILE%\.dsh\plugins\dsh-owui-chat2api-<版本>;然后在
   %USERPROFILE%\.dsh\profiles\<desktop|web>\package.json 的 dependencies 里加
   "dsh-owui-chat2api": "link:<该目录的绝对路径>",并把 "dsh-owui-chat2api"
   加进 dsh.profile.bundles 数组)
2. 重启 DSH。
3. 验证:DSH 页面右上角出现 OWUI 圆标;点开面板,Status 区能显示状态即成功。

Quick start 🚀

1. Restart DSH (after any install option above). The OWUI pill appears in the top-right corner.
2. Open the panel and set your Open WebUI URL (the default is a placeholder).
3. Click Start. The first run opens a browser window for a one-time sign-in; the session is reused afterwards.

Troubleshooting 🔧

Symptom	What to do
Diagnostics shows Attention	Install the dependencies: pip install requests playwright, then playwright install
Login fails / asks to sign in again	Click Login in the panel and sign in once in the window
Models missing from the DSH picker	Click Sync models & reasoning levels, then restart DSH
The URL is your-open-webui.example.com	That's the placeholder — set your real address, then Start

Reasoning effort 🧠

Reasoning models (e.g. served behind a vLLM gateway) honour reasoning_effort, so DSH's model picker can show Off / Low / Medium / High.

The easiest way is the Sync models & reasoning levels button in the Configuration section: it probes your models, declares the supported level for each, and writes a backup first. When your backend gains a model, click it again — already-probed models hit the cache.

For manual declaration or using chat2api.py standalone, see DEVELOPMENT.md.

Data & security 🔒

• Your Open WebUI session (.chrome-profile, token.json, the usage database) stays on this machine and is excluded from git and from the package.
• The usage database and the proxy config live under ~/.dsh, outside the plugin directory, so they survive plugin updates.
• The proxy listens on 127.0.0.1 only.

Development 🛠️

See DEVELOPMENT.md for the code layout, conventions and how to test a change locally.
