The open source one is the best. A reverse-engineered / decompiled source restoration of Anthropic's official [Claude Code](https://docs.anthropic.com/en/docs/claude-code) CLI tool. The goal is to reproduce most of Claude Code's functionality and engineering capabilities. It's abbreviated as CCB. [Documentation (Chinese)](https://ccb.agent-aura.top/) — PR contributions welcome. Sponsor placeholder. - [x] v1: Basic runability and type checking pass - [x] V2: Complete engineering infrastructure - [ ] Biome formatting may not be implemented first to avoid code conflicts - [x] Build pipeline complete, output runnable on both Node.js and Bun - [x] V3: Extensive documentation and documentation site improvements - [x] V4: Large-scale test suite for improved stability - [x] Buddy pet feature restored [Docs](https://ccb.agent-aura.top/docs/features/buddy) - [x] Auto Mode restored [Docs](https://ccb.agent-aura.top/docs/safety/auto-mode) - [x] All features now configurable via environment variables instead of `bun --feature` - [x] V5: Enterprise-grade monitoring/reporting, missing tools补全, restrictions removed - [x] Removed anti-distillation code - [x] Web search capability (using Bing) [Docs](https://ccb.agent-aura.top/docs/features/web-browser-tool) - [x] Debug mode support [Docs](https://ccb.agent-aura.top/docs/features/debug-mode) - [x] Disabled auto-updates - [x] Custom Sentry error reporting support [Docs](https://ccb.agent-aura.top/docs/internals/sentry-setup) - [x] Custom GrowthBook support (GB is open source — configure your own feature flag platform) [Docs](https://ccb.agent-aura.top/docs/internals/growthbook-adapter) - [x] Custom login mode — configure Claude models your way - [ ] V6: Large-scale refactoring, full modular packaging - [ ] V6 will be a new branch; main branch will be archived as a historical version > I don't know how long this project will survive. Star + Fork + git clone + .zip is the safest bet. > > This project updates rapidly — Opus continuously optimizes in the background, with new changes almost every few hours. > > Claude has burned over $1000, out of budget, switching to GLM to continue; @zai-org GLM 5.1 is quite capable. ## Quick Start ### Prerequisites Make sure you're on the latest version of Bun, otherwise you'll run into all sorts of weird bugs. Run `bun upgrade`! - [Bun](https://bun.sh/) >= 1.3.11 - Standard Claude Code configuration — each provider has its own setup method ### Install ```bash bun install ``` ### Run ```bash # Dev mode — if you see version 888, it's working bun run dev # Build bun run build ``` The build uses code splitting (`build.ts`), outputting to `dist/` (entry `dist/cli.js` + ~450 chunk files). The build output runs on both Bun and Node.js — you can publish to a private registry and run directly. If you encounter a bug, please open an issue — we'll prioritize it. ### First-time Setup /login After the first run, enter `/login` in the REPL to access the login configuration screen. Select **Anthropic Compatible** to connect to third-party API-compatible services (no Anthropic account required). Fields to fill in: | Field | Description | Example | |-------|-------------|---------| | Base URL | API service URL | `https://api.example.com/v1` | | API Key | Authentication key | `sk-xxx` | | Haiku Model | Fast model ID | `claude-haiku-4-5-20251001` | | Sonnet Model | Balanced model ID | `claude-sonnet-4-6` | | Opus Model | High-performance model ID | `claude-opus-4-6` | - **Tab / Shift+Tab** to switch fields, **Enter** to confirm and move to the next, press Enter on the last field to save - Model fields auto-fill from current environment variables - Configuration saves to `~/.claude/settings.json` under the `env` key, effective immediately You can also edit `~/.claude/settings.json` directly: ```json { "env": { "ANTHROPIC_BASE_URL": "https://api.example.com/v1", "ANTHROPIC_AUTH_TOKEN": "sk-xxx", "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4-5-20251001", "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6", "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-4-6" } } ``` > Supports all Anthropic API-compatible services (e.g., OpenRouter, AWS Bedrock proxies, etc.) as long as the interface is compatible with the Messages API. ## Feature Flags All feature toggles are enabled via `FEATURE_=1` environment variables, for example: ```bash FEATURE_BUDDY=1 FEATURE_FORK_SUBAGENT=1 bun run dev ``` See [`docs/features/`](docs/features/) for detailed descriptions of each feature. Contributions welcome. ## VS Code Debugging The TUI (REPL) mode requires a real terminal and cannot be launched directly via VS Code's launch config. Use **attach mode**: ### Steps 1. **Start inspect server in terminal**: ```bash bun run dev:inspect ``` This outputs an address like `ws://localhost:8888/xxxxxxxx`. 2. **Attach debugger from VS Code**: - Set breakpoints in `src/` files - Press F5 → select **"Attach to Bun (TUI debug)"** ## Documentation & Links - **Online docs (Mintlify)**: [ccb.agent-aura.top](https://ccb.agent-aura.top/) — source in [`docs/`](docs/), PR contributions welcome - **DeepWiki**: ## Contributors ## Star History Star History Chart ## License This project is for educational and research purposes only.
