Compare Bundles

If you're working with Tuist and need to understand why your app bundle just grew by 7MB, this is your debugging companion. It automates the tedious dance of fetching bundle metadata, comparing artifact trees between branches, and calculating size deltas for both install and download sizes. You can throw bundle IDs, dashboard URLs, or branch names at it and get a structured breakdown of what changed, whether new frameworks snuck in, or if someone added uncompressed assets. The real value is in the root cause analysis and actionable recommendations it surfaces, like suggesting asset compression or flagging debug symbols in release builds. It's opinionated about what counts as a regression (over 5% growth) and won't let you ignore it.
