GitHub Action (iOS)

(5 minute setup time)

The Emerge GitHub Action allows you to upload builds from a GitHub workflow.

The open source project can be viewed at


Not recommended for Android

Emerge recommends using the Emerge Gradle plugin as the primary integration point on Android. If using the Gradle Plugin, the GitHub action is not needed, as all upload functionality is built into the plugin.

Disclaimer: If you don't currently have a CI pipeline setup, we'd strongly recommend using Fastlane.


The Emerge upload action should be run on any event that should trigger a size analysis. Examples of this are:

  • When pushing or merging to specific branches (main/release).
  • On any PR to the main branch.

See action.yml for all inputs and descriptions.

Obtain an API key

Follow our steps on obtaining an API key.

Add the API key to your secrets in your repository or organization. Do not leave this key in plain text in your workflow!

Learn more about creating and using encrypted secrets.

Incorporate in your workflow

Build your artifact in a step before the Emerge upload action. Pass the generated artifact's path as the artifact_path argument, and your Emerge API key secret as the EMERGE_API_KEY argument:

name: Your workflow

    branches: [ main ]
    branches: [ main ]

    runs-on: ubuntu-latest
      - uses: actions/checkout@v2
      - name: Generate iOS release bundle
        run: # generate release build, e.g. with xcodebuild
      - name: Upload artifact to Emerge
        uses: EmergeTools/[email protected]
          artifact_path: path/to/
          emerge_api_key: ${{ secrets.EMERGE_API_KEY }}
          build_type: release # Optional, change if your workflow builds a specific type
