AI overview

Simon Willison evaluated Jeff Lindsay’s webframe as a scraping and sandboxing tool and reported scraping performance comparable to shot-scraper, alongside several browser limitations. His evaluation, prepared with Claude Opus 5.5, found Content Security Policy failures, a 0×0 viewport, page loads that hung, missing HTTP metadata, and limited browser controls. Willison described webframe as a fast, lightweight browser JavaScript runner for scraping. The findings identify practical rough edges in that use; the reported speed comparison does not establish its effectiveness as a sandbox.
