BundleCop

A tool that monitors application file sizes and alerts developers when they exceed set limits. It integrates with webpack and CI systems to track size changes across builds, helping teams identify which commits cause increases. The service is aimed at software developers and engineering teams in companies of various sizes, particularly those concerned with web performance. It is delivered as a SaaS with a CLI and webpack plugin, and can fail builds if thresholds are exceeded.
