### Less configuration. More coding.
-**One desktop app for your AI coding agents, providers, and model routes.**
-Connect a service. Review your configuration. Choose your fallback. Get back to building.
+**A local desktop workbench for Claude Code, Codex, and your other AI coding agents.**
+Built on [CC Switch](https://github.com/farion1231/cc-switch). Optional [HRouter](https://hrouter.net/) setup uses one OpenAI-compatible API key for Claude, GPT, Gemini, and the other models that key can call.

+
+## Quick start with HRouter
+
+[HRouter](https://hrouter.net/) is an API relay for coding tools such as Claude Code and Codex. You top up on the website, create one API key, and choose a group. That group decides which Claude, GPT, Gemini, and other models the key can call, and what they cost. The desktop app does not include account, top-up, or order pages. No HRouter account is required to use other providers.
+
+1. **Create a key on the website.** Sign in at [hrouter.net](https://hrouter.net/). Check models and groups, then create a key from **API 密钥** and pick a group that matches the tool you want. Balance, subscription benefits, and key groups are separate: topping up does not grant every group. The order of steps is in the [HRouter docs](https://www.hrouter.net/docs/index).
+2. **Install [v0.4.2](#download).** Open the workbench and select an agent. Claude Code and Codex are the usual starting points.
+3. **Add the key in the app.** Choose **Add HRouter key**, paste the key, and click **识别 Key**. The app reads the models that key can actually call. That button label stays Chinese when the interface is set to English. The key is stored only in the local configuration.
+4. **Review, save, and enable.** Check the model mapping, then enable the provider. Refresh or restart the client if it was already open.
+
+Official providers, a self-hosted endpoint, or another OpenAI-compatible LLM gateway use the same workbench. HRouter quick setup is optional.
+
+## Use the same key in Claude Code and Codex
+
+You can also point the CLIs at HRouter yourself. These base URLs are from the [HRouter docs](https://www.hrouter.net/docs/index). Website paths such as `/home` and `/keys` are not API addresses.
+
+| Client | Base URL | Guide |
+| ---------------------------------------------- | ------------------------- | --------------------------------------------------------------------- |
+| Claude Code (Anthropic Messages) | `https://hrouter.net` | [Claude Code tutorial](https://www.hrouter.net/docs/claude-code) |
+| Codex and other OpenAI-compatible clients | `https://hrouter.net/v1` | [Codex tutorial](https://www.hrouter.net/docs/codex) |
+
+Claude Code appends `/v1/messages` itself. Setting its base URL to `https://hrouter.net/v1` returns 404.
+
+`~/.claude/settings.json` on macOS and Linux, or `%USERPROFILE%\.claude\settings.json` on Windows:
+
+```json
+{
+ "env": {
+ "ANTHROPIC_BASE_URL": "https://hrouter.net",
+ "ANTHROPIC_AUTH_TOKEN": "sk-xxxxx"
+ }
+}
+```
+
+Replace `sk-xxxxx` with your key. If your Claude Code build reads `ANTHROPIC_API_KEY` instead, use the same key there.
+
+Codex uses the OpenAI Responses API. The provider block in `~/.codex/config.toml` (Windows: `%USERPROFILE%\.codex\config.toml`):
+
+```toml
+model_provider = "hrouter"
+
+[model_providers.hrouter]
+name = "OpenAI"
+base_url = "https://hrouter.net/v1"
+requires_openai_auth = true
+wire_api = "responses"
+```
+
+Put the key in `~/.codex/auth.json` as `OPENAI_API_KEY`. The docs require `name = "OpenAI"` exactly, so Codex remote compaction can run, and `wire_api = "responses"`. Model ids change; pick one your key returns from `https://hrouter.net/v1/models`. Context-window presets and the rest of the file are in the [Codex tutorial](https://www.hrouter.net/docs/codex).
+
+**识别 Key** in HRouter Desktop writes this configuration for the selected agent. Keep manual edits and the desktop app pointed at the same base URL.
+
## Why HRouter Desktop?
Different agents. Different config files. Different providers. Switching your coding setup should not mean piecing all of them together again.
-**HRouter Desktop puts the connection workflow in one place:** providers, API keys, model mappings, configuration protection, backup routes, and usage. Built on CC Switch, it adds an agent-first interface and a focused workflow for the services you choose.
+**HRouter Desktop puts the connection workflow in one place:** providers, API keys, model mappings, configuration protection, backup routes, and usage. Built on CC Switch, it is a desktop CC Switch alternative: an agent-first interface for the services you choose, including an OpenAI-compatible API relay or another LLM gateway.
- **11 agents, one workbench.** Move between Claude Code, Codex, Gemini CLI, and more without learning a different configuration UI for each.
- **Switch with a preview, not a guess.** Opt into Claude / Codex configuration protection to preserve custom fields, preview changes, and keep local switch snapshots.
