Onit – Source-available ChatGPT Desktop with local mode, Claude, Gemini▲174
Hey Hackernews- it’s Tim Lenardo and I’m launching v1 of Onit today! Onit is ChatGPT Desktop, but with local mode and support for other model providers (Anthropic, GoogleAI, etc).

GodMode – open-source AI Chat Browser▲12
Hi HN, we're Sean, Alec, and swyx, and we've been hacking on this side project that harmonizes all the major AI chat apps (Closed LLMs, Open Source Hosted LLMs, and Local/GGML ones too) and lets you invoke them in one keyboard shortcut. I originally made this as a smol menubar app that could quickly access ChatGPT from wherever I was on desktop. This necessitated writing an Electron app, rather than a Chrome extension. I also didn't have access to the GPT-4 API at the time, so I preferred to use GPT-4 via the full webapp. Then Bing came out strong, and Bard, and Claude, and Llama, and…

I Wrote an Open-Source Alternative to OpenAI Operator – For Any LLM▲15
Hey HN, I built browser-use, an open-source alternative to OpenAI’s Operator for browser-use systems, and here’s why I think it’s better: Flexibility: You can use any LLM with our tool – Gemini, Anthropic, Qwen, Llama, DeepSeek, and more. As new models improve, so does your agent. Open Source: No need to pay $200/month or endure long waitlists – it’s free and accessible to everyone today. Custom Automation: Our Python package allows you to build actual web automations. Your LLM can gain new tools, like file uploads. Cost: Our system is 30x cheaper than Operator, e.g., when used with…
