webframe: evaluated as a scraper and a sandbox

Jeff Lindsay's neat little project, webframe, allows developers to "run a web page like a program."

This utility accepts a URL or a local file, executing its contents within a hidden, headless web view. It then directs `console.log()` output to standard output and any exceptions to standard error.

The tool is constructed using Go, leveraging the glaze library. This library grants access to the operating system's native browser components—specifically "WKWebView on macOS, WebKitGTK on Linux, WebView2 on Windows"—meaning webframe avoids bundling its own browser engine.

The functionality brings to mind the author's own shot-scraper javascript tool, though webframe is presented in a much smaller package that bypasses dependency on Playwright.

To assess its capabilities, Claude Opus 5.5 was tasked with rigorous testing and generating a research report. The prompt given to the AI instructed it to: "Explore https://github.com/tractordev/webframe try running it and put it though its paces, build a few exploratory prototypes, then evaluate it as a potential sandboxing tool and as a tool for scraping web pages using the same patterns encouraged by the 'shot-scraper JavaScript' command (see simonw/shot-scraper on GitHub, docs directory)."

This evaluation considers webframe's potential as both a sandboxing utility and a web page scraping instrument.
