Webpack Monitor: open-source developer tools

About Webpack Monitor

Webpack Monitor is a configurable Webpack plugin paired with an interactive analysis tool for understanding how a production bundle is composed. It is aimed at developers who want to track optimization metrics over time and prioritize which parts of a bundle are worth optimizing, rather than digging through raw Webpack stats manually.

The plugin captures build statistics whenever meaningful changes to bundle composition occur, skipping captures when a build does not differ from the most recent one on record, and can optionally launch a local analysis server to visualize how bundles have changed between builds. Configuration options let developers choose where build data is saved, which port the local server runs on, and whether emitted source maps are excluded from the captured stats.

The README states plainly that Webpack Monitor is not currently maintained. It is published to npm as webpack-monitor, written in JavaScript, and released under the MIT license, so existing users can continue to use it but should not expect new features or fixes.
