Sandboxed Browser Implementation Mechanisms
Kernel Images creates a fully isolated runtime sandbox for each instance through a deeply customized Chrome environment. This isolation is not only at the process level, but also at the system level through unikernel technology. The sandboxed browser provided by the project has the following key features: full support for the Chrome DevTools protocol, noVNC remote access integration by default, compatibility with major automation frameworks (Playwright/Puppeteer), and built-in support for Anthropic agents. The unikernel implementation is particularly noteworthy, as it allows the browser to automatically hibernate to near-zero resource usage when inactive, with a snapshot mechanism that preserves the full state of the session.
- Isolation level: container level + unikernel system level double isolation
- Compatibility: complete support for DevTools protocol and mainstream testing frameworks
- State Management: Unique dormant snapshot mechanism to maintain session persistence
