cc-haha: A local-first, cross-platform desktop workspace for Claude Code

cc-haha is a desktop app written in TypeScript and Electron, bringing a multi-session workspace, global search, branch/Worktree launching, per-file diff review, a built-in browser preview, five-tier permission approval, and model request tracing into a single interface. Model access covers official account logins for Claude, ChatGPT, and Grok, third-party presets like DeepSeek, Kimi, and Zhipu GLM, plus local endpoints from LM Studio and Ollama. The desktop also offers graphical MCP management, visual SubAgent management, an Agent Teams collaboration workspace, and dynamic Workflow orchestration. For developers who use Claude Code daily, this update removes the cost of switching between multiple terminal windows and manually managing Git Worktrees; teams running local open-source models can connect directly to LM Studio or Ollama endpoints without maintaining a separate multi-model configuration. Computer Use runs natively on macOS and doesn't take over the real mouse and keyboard, so those automating long workflows can keep working while the Agent operates other apps. H5 remote access and IM integrations like Telegram, Feishu, and DingTalk let users approve permissions and switch projects after locking the screen or changing devices. Licensing uses the cc-haha Community Source License 1.0, allowing personal non-commercial use and internal enterprise use, but work-for-hire, external commercial profit, derivative development, and commercial distribution require written authorization—making it a source-available license rather than an OSI-approved open-source license.
