Bundlewatch is a CLI tool and GitHub App that helps prevent unexpected bloat in your JavaScript bundles. It compares the size of your bundles across pull requests. Define size budgets for your JavaScript assets, and Bundlewatch reports any size regressions directly in your pull requests as a comment. This process keeps your team informed about bundle size changes, ensuring optimal performance and preventing performance degradation due to oversized bundles. It's ideal for modern web development workflows.
Bundlewatch npm package downloads show a general upward trend from March 2024 to August 2025, peaking in June 2025. There's been substantial growth over the period, but September 2025 data is incomplete and shows a sharp decline, making it difficult to assess the current trend accurately.
Bundlewatch's npm package release frequency is sporadic. Initial development in May 2018 saw 6 releases. Releases occurred intermittently until September 2020 with a peak of 4 releases in June 2019. After a few individual releases in 2021 and 2022, activity seems to have slowed down considerably, with only one release in July 2024 and one in April 2025, followed by no releases in the subsequent months.
