10 alternatives to cat-catch

xifangczy/cat-catch — 猫抓 浏览器资源嗅探扩展 / cat-catch Browser Resource Sniffing Extension (22,485 stars, GPL-3.0, ui, scraping, integration).

These are the closest projects in the JustClaw-It index that we serve licence-cleared code from, ranked by relevance and by our code-quality score (1–10, the mean over each repo's graded components: completeness, code quality, deployability, reusability, strategic value). JustClaw-It does not serve code from xifangczy/cat-catch itself (licence class: strong-copyleft), so these alternatives are the licence-cleared route.
