We build tools for developers working with agents — especially **coding agents**.\n\nToday, we’re launching **VibeKit**, our open-source SDK that lets you run coding agents like OpenAI Codex or Claude Code safely in secure sandboxes.\n\nLocal setups work great for developing with coding agents — we’ve used them ourselves. But as soon as you want to **embed agents into your app**, **automate GitHub workflows**, or **run tasks in isolated environments**, you need something more flexible and secure.\n\n**VibeKit makes this possible.** It supports multiple sandbox providers (E2B today; Daytona, Modal, and [Fly.io](http://Fly.io) coming soon) and gives you:\n\n* ✅ Safe, isolated code execution\n* ✅ Live output streaming\n* ✅ Async run handling\n* ✅ Full prompt + code history\n* ✅ Telemetry and tracing\n* ✅ GitHub-safe automations\n\nWith VibeKit, coding agents can install packages, modify files, or create PRs — all without touching your local or production systems.\n\nhttps://youtu.be/GQaOSEbvOxM\n\nWe originally built VibeKit for internal use while developing Superagent. Since then we’ve used it to:\n\n* Embed coding agents inside apps\n* Build GitHub bots that open issues and PRs\n* Automate internal workflows (e.g. adding PostHog)\n\nNow it’s fully open source (MIT licensed) and available for anyone to use.\n\n🌐 [vibekit.sh](http://vibekit.sh) \n\n💻 [github.com/superagent-ai/vibekit](http://github.com/superagent-ai/vibekit) \n\n### 🙏 **Our Ask**\n\n* ⭐️ Star the repo\n* 🧪 Try embedding a coding agent in your app\n* 💬 Tell us what use cases it unlocked for you — email [founders@superagent.sh](mailto:founders@superagent.sh)\n\n![uploaded image](/media/?type=post\u0026id=91137\u0026key=user_uploads/1367556/d5bc1c0b-6a66-42b4-b75d-b28d6237e1a6)\n\n","slug":"Nhx-vibekit-run-coding-agents-in-a-secure-sandbox","created_at":"2025-06-09T13:57:54.068Z","updated_at":"2026-05-25T03:14:07.260Z","total_vote_count":18,"url":"https://www.ycombinator.com/launches/Nhx-vibekit-run-coding-agents-in-a-secure-sandbox","share_image_url":"https://www.ycombinator.com/media/?type=post\u0026id=91137\u0026key=user_uploads/1367556/d5bc1c0b-6a66-42b4-b75d-b28d6237e1a6","company":{"id":29374,"name":"Superagent","slug":"superagent","url":"https://superagent.sh/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/a5fb7dd012389ddf81869040550578bb786988ed.png","batch":"Winter 2024","industry":"B2B","tags":["Artificial Intelligence","Security","Open Source","AI"],"search_path":"https://bookface.ycombinator.com/company/29374"}}
