Running a headless browser inside your agent sandbox is the default, but it can be brittle.
Cold starts. CAPTCHAs. Auth state lost on restart. Proxies.
Our new template built with friends
@usekernel splits the loop. The agent runtime runs in the e2b sandbox. The browser runs on Kernel, which handles cold start, CAPTCHA, residential proxies, and session persistence across hours. Connect them over CDP.
Three things you can build with it this weekend.
→ Screenshot app endpoints. Deploy a web app in a sandbox, screenshot every route.
→ Agent data extraction. Let an LLM autonomously browse and extract data.
→ Live browser preview. Watch the browser in real time via Kernel's live view.
