The creator developed it after five iterations of an 'Agentic OS' to address the challenge of hosting and managing 100x more code, using rootless namespaces and a central service proxy to enforce permissions between apps. The workspace is designed to be familiar to LLMs, appearing as a basic web app, and supports bring-your-own-agent with harnesses like Claude Code.", "body_md": "Started with the problem \"how do I host and manage 100x more code over the next few years\".\n\nI wrote 5 iterations of 'Agentic OS' over the past few months, this one seems to finally be the correct shape.\n\nTried WASM runtimes / WASM-OS, containers, k8s, microVMs, functions/lambda - all of that fell short, was too far out of distribution to work well with LLMs, wasted too many resources, etc.\n\nThis one is doing heavy use of rootless namespaces, with central service proxy enforcing permissions between apps, and mix of binds/overlays that ensure reasonable data security, and is all super familiar to LLMs because everything looks like a very basic web app.\n\nYou bring your own Agent - the workspace itself actually does not have any central Agent to it. You write apps inside, in harnesses like Claude Code or anything you like.\n\nWith this runtime you don't have a mess of services all on localhost or random vm all deployed in random ways and with no/weak guardrails.\n\nComments URL: [https://news.ycombinator.com/item?id=49184296](https://news.ycombinator.com/item?id=49184296)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-xbin-the-app-workspace-you-rewrite-from-inside", "canonical_source": "https://xbin.dev/", "published_at": "2026-08-05 15:28:28+00:00", "updated_at": "2026-08-05 15:37:00.306548+00:00", "lang": "en", "topics": ["developer-tools", "ai-agents", "ai-infrastructure"], "entities": ["XBin", "Claude Code", "Hacker News"], "alternates": {"html": "https://wpnews.pro/news/show-hn-xbin-the-app-workspace-you-rewrite-from-inside", "markdown": "https://wpnews.pro/news/show-hn-xbin-the-app-workspace-you-rewrite-from-inside.md", "text": "https://wpnews.pro/news/show-hn-xbin-the-app-workspace-you-rewrite-from-inside.txt", "jsonld": "https://wpnews.pro/news/show-hn-xbin-the-app-workspace-you-rewrite-from-inside.jsonld"}}
