Screenbox

What it does

Watch your AI agent open Chrome, navigate sites, fill forms, and click buttons on a real Linux desktop it controls completely. Screenbox gives AI agents (Claude, GPT, etc.) a full virtual desktop via MCP. No API hacks. No headless browser workarounds. The agent sees the screen and acts on it - just like you would. Real Chromium per agent. Live view watch it work, grab control anytime. Docker, ~2GB RAM, no GPU. Snapshots and human-in-the-loop. Open source. Self-hosted. Your data stays yours.

Real virtual desktops for AI agents. MCP-native, Docker-isolated, self-hosted. Give Claude, Cursor, and Copilot their own screen.

Real desktops with a real browser and real desktop applications. Full isolation, full automation, MCP-native. Give Claude, Cursor, and Copilot their own screen. An AI agent creates a desktop, opens Chromium, navigates websites, takes screenshots, and extracts data — all through MCP tools. Agents lose everything they learned when a session ends. Screenbox fixes this. Action logs from past sessions are compiled into declarative knowledge facts and auto-injected into future interactions. Your agent gets smarter every time itfrom screenbox.dev

  I've been building computer-use tools for a while, and I quietly launched this about a month ago (122 Stars on GH). I figured it was worth sharing here. Over the last few months, a lot of computer-use agents have come out: Codex, Claude Code, CUA, and others. Most of them seem to work roughly like this: 1. Take a screenshot 2. Have the model predict pixel coordinates 3. Click x,y 4. Take another screenshot 5. Repeat That works, but it's slow, expensive in tokens, and fragile. If the UI shifts a few pixels, things break. And the model still doesn't know what any element actually is. But the…

  Hi HN, I forked chromium and built agent-browser-protocol (ABP) after noticing that most browser-agent failures aren’t really about the model misunderstanding the page. Instead, the problem is that the model is reasoning from a stale state. ABP is designed to keep the acting agent synchronized with the browser at every step. After each action (click, type, etc), it freezes JavaScript execution and rendering, then captures the resulting state. It also compiles the notable events that occurred during that action loop, such as navigation, file pickers, permission prompts, alerts, and downloads,…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
