Get started with Capgo Cloud Build and create your first iOS or Android native build in minutes.

What You’ll Need

Section titled “What You’ll Need”

Before you begin, ensure you have:

  • A Capacitor app that builds successfully locally
  • Node.js 20 or higher installed
  • A Capgo account with an active subscription
  • Your app already registered in Capgo (run npx @capgo/cli@latest app add if not)
  • Build credentials configured (certificates, keystores) - see below

Before Your First Build

Section titled “Before Your First Build”

⚠️ Setup Credentials First

Required before building: You must configure your build credentials (certificates for iOS, keystores for Android).

Setup Credentials →

Quick Start

Section titled “Quick Start”

  1. Setup Build Credentials

    Before you can build, you need to save your credentials locally:

    For iOS:

    Terminal window
    npx @capgo/cli build credentials save \
      --platform ios \
      --certificate ./cert.p12 \
      --p12-password "password" \
      --provisioning-profile ./profile.mobileprovision \
      --apple-key ./AuthKey.p8 \
      --apple-key-id "KEY123" \
      --apple-issuer-id "issuer-uuid" \
      --apple-team-id "team-id"

    For Android:

    Terminal window
    npx @capgo/cli build credentials save \
      --platform android \
      --keystore ./release.keystore \
      --keystore-alias "my-key" \
      --keystore-key-password "key-pass" \
      --keystore-store-password "store-pass"

    See the full credentials guide for details.

  2. Verify Local Build

    First, ensure your app builds locally without errors:

    Terminal window
    # Build your web assets
    npm run build
    

    # Sync with Capacitor
    npx cap sync
    

    # Test local build (optional but recommended)
    npx cap open ios    # For iOS
    npx cap open android # For Android

  3. Authenticate with Capgo

    Set your Capgo API key (if not already configured):

    Terminal window
    npx @capgo/cli@latest login

    Or set the environment variable:

    Terminal window
    export CAPGO_TOKEN=your_api_key_here

  4. Run Your First Build

    Start with an Android debug build (fastest to test):

    Terminal window
    npx @capgo/cli@latest build com.example.app \
      --platform android \
      --build-mode debug

    You’ll see real-time logs as your build progresses:

    ✔ Creating build job...
    ✔ Uploading project (15.2 MB)...
    ✔ Build started
    

    📝 Build logs:
    → Installing dependencies...
    → Running Gradle build...
    → Signing APK...
    ✔ Build succeeded in 3m 42s

  5. Check Build Status

    The CLI will automatically poll and display the build status. Once complete, you’ll see:

    • Build time
    • Success/failure status
    • App submitted to App Store/Play Store (if credentials configured)

Understanding the Build Process

Section titled “Understanding the Build Process”

When you run the build command, here’s what happens:

graph LR
    A[Your Machine] -->|1. Zip Project| B[Local Temp]
    B -->|2. Upload| C[Capgo Cloud]
    C -->|3. Build| D[Build Server]
    D -->|4. Logs Stream| A
    D -->|5. Cleanup| E[Auto Delete]
  1. Local Preparation - Your project is zipped (excluding node_modules and dotfiles)
  2. Upload - The zip is uploaded to secure cloud storage (Cloudflare R2)
  3. Build Execution - Your app builds on dedicated infrastructure
  4. Log Streaming - Real-time logs stream to your terminal via Server-Sent Events
  5. Automatic Cleanup - Build artifacts are deleted (Android: instant, iOS: 24 hours)

Your First Production Build

Section titled “Your First Production Build”

Once you’ve verified the process works, create a production build:

Android

Section titled “Android”
Terminal window
npx @capgo/cli@latest build com.example.app \
  --platform android \
  --build-mode release

You’ll need to configure signing credentials first. See Android Build Configuration.

iOS

Section titled “iOS”
Terminal window
npx @capgo/cli@latest build com.example.app \
  --platform ios \
  --build-mode release

iOS builds require signing certificates and provisioning profiles. See iOS Build Configuration.

What Gets Built

Section titled “What Gets Built”

Important: Capgo Cloud Build only builds the native parts of your app (iOS and Android native code).

You are responsible for:

  • Building your web assets (npm run build)
  • Running npx cap sync before the build
  • Ensuring all dependencies are in package.json

We handle:

  • Native iOS compilation (Xcode, Fastlane)
  • Native Android compilation (Gradle)
  • Code signing
  • App store submission (if configured)

Build Time & Costs

Section titled “Build Time & Costs”

Build time is measured from start to completion:

  • Android: Typically 3-5 minutes (1× billing multiplier)
  • iOS: Typically 5-10 minutes (2× billing multiplier due to Mac hardware costs)

You only pay for actual build time used. No hidden fees.

Common Use Cases

Section titled “Common Use Cases”

CI/CD Integration

Section titled “CI/CD Integration”

Add to your GitHub Actions workflow:

Test builds locally before committing:

Terminal window
# Quick debug build for testing
npm run build && npx cap sync
npx @capgo/cli@latest build com.example.app \
