We put grok 4.5 and opus 4.8 head to head on the same browser task, on Hyperbrowser Sandboxes. We then asked it to open a page in a real sandboxed browser and pull the title. Grok build on Grok 4.5, Claude code on Opus 4.8, identical setup. Grok 4.5 came out ahead ↓

We gave AI agents their own computer. Sub-50ms startup. Memory snapshots. Full terminal access. Filesystem API. Persistent volumes. All in one sandbox. Hyperbrowser Sandboxes ↓

Grok 4.5 excels at skills and MCP use

You don't need your agent to explore a site every time. Built Agentmap, it crawls it once and turns it into a structured map, pages, flows, the data on each page. the agent loads it and goes straight to work. Open-source, Powered by @hyperbrowser
You don't need to read code anymore. Read architectural changes first, then code, if necessary. Hey Claude, walk me through your architectural changes (before/after) in an html file: modules and their dependencies, seams, function signatures, etc. use visuals like mermaid diagrams. This works better if 1. you've given Claude a lot of ways to verify its work 2. you're iterating on architectural decisions with Claude upfront, before code gets written

/harness A Claude Code plugin built for Fable 5. It runs your agent against your project, watches it break, and writes a CLAUDE. md from the actual failures. It catches wrong paths, missing scripts, and bad assumptions so your agent never hits the same wall twice ↓

your agent needs a machine for thirty seconds, not thirty days. spin up a full linux box in under 50ms. run the task. throw it away when it's done. disposable compute for agents ↓

これは良さそう。AIエージェントが二度とサイトで迷子にならない発想ツール、Hyperbrowserの「/web」が公開。 ブラウザ操作系AIが失敗するのは「構造を知らないまま突っ込むから」 /web はURLを渡すだけで、全ページ・操作・フロー・押せる要素を1枚の web .md に書き出す。エージェントに“サイトの間取り図”を先渡しする。 ・任意サイトの構造をMarkdown化(web. md) ・ページ/ユーザーフロー/インタラクティブ要素まで網羅 ・Claude Code・Cursorにそのまま貼れる ・SEO用sitemapではなく「AIエージェント用sitemap」 ↓詳細

معظم أدوات الذكاء الاصطناعي ترى الكود. لكنها لا ترى الموقع. ولهذا تفشل أحيانًا في فهم ما يحدث بعد تشغيل التطبيق. Hyperbrowser MCP يحل هذه المشكلة بطريقة ذكية. بدل أن يعتمد Claude Code على الملفات فقط، يصبح قادرًا على: → فتح الموقع → التنقل بين الصفحات → الضغط على الأزرار → تعبئة النماذج → التقاط Screenshots → فهم رحلة المستخدم الفعلية ومن ثم إنشاء ملف web.md يحتوي على خريطة كاملة للموقع: • الصفحات • التدفقات • الإجراءات • العناصر التفاعلية الفائدة الحقيقية ليست بناء تصميم جديد. الفائدة أن الوكيل يتوقف عن التخمين. ويبدأ بفهم الموقع كما يراه المستخدم. ومع ازدياد تعقيد التطبيقات، أعتقد أن ملفات web.md ستصبح مهمة مثل ملفات CLAUDE.md داخل المشاريع. واحد يشرح الكود. والآخر يشرح الموقع.
/web Creates a web. md file for any website. Every page, action, flow, and interactive element your coding agent needs to navigate it. AI agents fail on websites because they don't know the structure. Web. md gives them the map before they start ↓

(4/n) 【展望】 開発はYC出身のHyperbrowser。先行作 DESIGN.md(デザイン抽出)→ web.md と、サイトを.mdに変換する発想で一貫してる。 近いうち、サイト側が自前で web.md を置く「AI向け説明書を同梱する」文化が来るかも。 出典: hyperbrowser.ai 元投稿: xitter.cf/hyperbrowser/status/20…

Your AI coding agent can now extract any website's design system directly from the terminal. /design Fetches the branding. Extracts colors, fonts, spacing, components. Saves it as a DESIGN. md Powered by Hyperbrowser. Setup guide ↓

Generate a full Web md file for any site with /web Every page, action, flow & interactive element mapped out before your agent touches it. AI agents fail on websites because they go in blind. This gives them the blueprint first.

xAI open-sourced the algorithm that scores every tweet on X. 19 engagement signals. Replies 13.5x. Reposts 20x. Bookmarks 10x. We built PhoenixScore. Paste a tweet. It runs through the algorithm and shows you exactly how it scores. Open source. Powered by Hyperbrowser.

Your AI agents are wasting 90% of their context window on noise. I built an open-source tool to fix that. Paste a URL. Get only what matters. Key facts, tables, code, stats, entities. Structured, sourced, ready to use. Same page. 100x fewer tokens. Fewer hallucinations.

We pointed our agent at @karpathy and told it to learn everything. It found his latest work, browsed his gists, repos, and posts. Generated skills you can drop into Claude Code, Cursor, or Codex. Type anyone. Your agent learns from them. Open source. Powered by Hyperbrowser ↓
