Introducing Browser Sandbox

$npx -y @buildinternet/releases show rel_vx7axHNq9qczHGWtTSIO-

Browser Sandbox gives agents a secure, fully managed browser environment for interactive web automation with no local setup, Chromium installs, or driver compatibility issues. Each session runs in an isolated, disposable sandbox that scales without infrastructure management.

Key Features:

  • Browser Sandbox — Launch secure, isolated browser sessions with Python, JavaScript, and bash execution. Pre-installed with agent-browser CLI and Playwright.
  • Multi-Language Support — Execute Python, JavaScript, or bash code remotely via API, CLI, or SDK with instant results.
  • agent-browser Integration — Pre-installed CLI with 40+ commands for AI agents to write simple bash commands instead of complex Playwright code.
  • Live View & CDP Access — Watch sessions in real time via embeddable stream URL or connect own Playwright instance over WebSocket.
  • Session Management — Configurable TTL controls, parallel sessions (up to 20 concurrent), and automatic cleanup. 2 credits per browser minute with 5 minutes free.
