# Size Analyzer by Bitrise

> Free tool to analyze iOS and Android app bundle sizes. Upload an IPA, APK, or AAB to get a full breakdown of frameworks, assets, resources, and executables with optimization recommendations.

Size Analyzer is available as a web tool, a Bitrise CLI plugin, and a Bitrise CI step.

## Web Tool

- [Dashboard](https://bitrise.io/size-analyzer): Browse pre-analyzed top apps or upload your own
- [Guide](https://bitrise.io/size-analyzer/guide): How to use the tool via web, CLI, or CI

## CLI Plugin

Install the Bitrise CLI and bundle inspector plugin to analyze builds locally:

```
brew install bitrise && bitrise setup
bitrise plugin install https://github.com/bitrise-io/bitrise-plugins-bundle-inspector.git
bitrise :bundle-inspector analyze /path/to/app.ipa
```

Output formats: text, json, markdown, html.

## CI Step

Add `bundle-analyzer@1` to your Bitrise workflow. It auto-detects IPA/APK/AAB artifacts, posts analysis as GitHub PR comments, and can fail builds when size exceeds a threshold.
