webpack vs pytest-testmon
webpack has 65,945 GitHub stars, 9,545 forks, 123 open issues and last shipped today. pytest-testmon has 1,015 stars, 81 forks, 38 open issues and last shipped 10 months ago. webpack leads on adoption by 6,397% (65,945 vs 1,015 stars). webpack is written in JavaScript under MIT; pytest-testmon is written in Python under MIT. webpack has attracted 14% as many forks as stars, pytest-testmon 8%. webpack was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (build-tool), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About webpack
webpack is an open source module bundler for JavaScript and related assets, distributed under the MIT license and published to npm. It lives in the JavaScript ecosystem, where the README describes its main purpose as bundling JavaScript files for use in a browser, while also being capable of transforming, bundling, or packaging just about any resource or asset. Loaders let modules arrive in many forms — CommonJS, AMD, ES6 modules, CSS, images, JSON, CoffeeScript, LESS, or custom formats — and the plugin system extends what the build can do.
