Hob: Open-Source On-Device Alternative to Claude Cowork and ChatGPT

Developer Christian launched Hob, an MIT-licensed open-source desktop app for Mac, Windows, and Linux that runs open-weight models (e.g., Gemma 4, gpt-oss) locally to process files. Features include automatic model selection, sandboxed Python code, built-in web search, MCP support, and image recognition. All chats and files stay on-device, with fully offline operation, aiming to provide ChatGPT/Claude-like file processing while ensuring privacy.
