Octoweb – a free, open-source keyboard-first browser for macOS
Free, open source browser for macOS. Command palette, AI sidebar over ACP, and a built-in MCP server your agents can drive. WebKit and Rust, no Electron.
What it does
Octoweb is a keyboard-first AI browser for macOS. WebKit and Rust — no Electron, no Chrome, no mouse required. The command palette is the whole interface, the AI lives in a sidebar instead of a tab, and your agents can drive the browser directly over MCP. Most browsers are built around the mouse and bolt shortcuts on afterwards. Octoweb starts from the keyboard, so the fast path is the only path. Type a URL, a search, or any fragment of a page title you have seen before. Open tabs and history are fuzzy-matched together and ranked by match quality and how often you actually go back. Pin the docs you live in to a numbered slot with ⌘⇧1–0 and land back on them from anywhere. Slots survive…from octoweb.xyz

Hey HN! I built a native macOS desktop client for Hacker News and I'm open-sourcing it under the MIT license. GitHub: https://github.com/IronsideXXVI/Hacker-News Download (signed & notarized DMG, macOS 14.0+): https://github.com/IronsideXXVI/Hacker-News/releases Screenshots: https://github.com/IronsideXXVI/Hacker-News#screenshots I spend a lot of time reading HN — I wanted something that felt like a proper Mac app: a sidebar for browsing stories, an integrated reader for articles, and comment threading — all in one window.…

- WPWe packaged an MCP server inside ChromiumOct 2025 · github.com · ▲46
Hey HN, we just shipped a browser with an inbuilt MCP server! We're a YC startup (S24) building BrowserOS — an open‑source Chromium fork. We're a privacy‑first alternative to the new wave of AI browsers like Dia, Perplexity Comet. Since launching ~3 months ago, the #1 request has been to expose our browser as an MCP server. -- Google beat us to launch with chrome-devtools-mcp (solid product btw), which lets you build/debug web apps by connecting Chrome to coding assistants. But we wanted to take this a step further: we packaged the MCP server directly into our browser binary. That gives…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
