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.

Compare Bundles
Quick Start
You'll typically receive two bundle identifiers. Follow these steps:
- Run
tuist bundle list --jsonto find bundles on each branch. - Run
tuist bundle show <bundle-id> --jsonfor both base and head bundles. - Compare artifact trees with
tuist bundle artifact list <bundle-id> --json. - Compare install size, download size, and other metadata.
- Summarize size changes with actionable recommendations.
Step 1: Resolve Bundles
If base/head are bundle IDs or dashboard URLs
Fetch each directly:
tuist bundle show <base-id> --json
tuist bundle show <head-id> --json
If base/head are branch names
List recent bundles on each branch and pick the latest:
tuist bundle list --git-branch <base-branch> --json
tuist bundle list --git-branch <head-branch> --json
Then fetch full details with tuist bundle show <id> --json.
Defaults
- If no base is provided, use the project's default branch (usually
main). - If no head is provided, detect the current git branch.
Step 2: Compare Artifact Trees
After fetching both bundles with tuist bundle show <id> --json, compare the individual artifacts:
