# webframe: evaluated as a scraper and a sandbox

## Retrieval answer

Simon Willison published an exploratory evaluation of webframe, a Go project by Jeff Lindsay that runs a web page or file in a hidden headless web view.

Simon Willison published an exploratory evaluation of webframe, a Go project by Jeff Lindsay that runs a web page or file in a hidden headless web view. It sends `console.log()` output to standard output and exceptions to standard error.

webframe is built on the glaze library and uses a system browser rather than bundling a browser engine: WKWebView on macOS, WebKitGTK on Linux, and WebView2 on Windows. Willison compares its intended scraping use to his shot-scraper JavaScript tool, while noting that webframe is a smaller package without a Playwright dependency.

For the evaluation, Willison asked Claude Opus 5.5 to run the project, build exploratory prototypes, and assess it as both a scraping tool and a potential sandbox. The source establishes that this was an exploratory assessment. It does not establish a formal security review, containment guarantees, resistance to sandbox escape, or suitability for executing untrusted code.
