Introduction to Capgo Build

このコンテンツはまだあなたの言語で利用できません。

Capgo Build is a cloud-based native app compilation service for Capacitor apps. It lets you build iOS and Android apps without maintaining local development environments - no Xcode, no Android Studio, no Mac hardware required.

What Capgo Build Does

Capgo Build compiles the native parts of your Capacitor app in the cloud:

iOS builds run on dedicated Apple Silicon (Mac Mini M4) machines
Android builds run in isolated Docker containers
Automatic code signing handles certificates, provisioning profiles, and keystores
Direct store submission uploads signed apps to App Store Connect and Google Play

You trigger builds with a single CLI command that works from anywhere - your local machine, GitHub Actions, GitLab CI, or any CI/CD pipeline.

When to Use Capgo Build vs Live Updates

Capgo offers two complementary features for updating your app. Here’s when to use each:

Scenario	Live Updates	Capgo Build
Bug fix in JavaScript/TypeScript code	✓
UI changes (HTML, CSS, images)	✓
Updating web dependencies	✓
Adding or removing a Capacitor plugin		✓
Updating a native SDK version		✓
Changing native permissions (Info.plist, AndroidManifest)		✓
Updating Capacitor version		✓
Modifying native code (Swift, Kotlin, Java)		✓
Changing app icon or splash screen		✓
First app store submission		✓

Why Use Capgo Build

No Mac Required for iOS

Build and ship iOS apps without Mac hardware. Anyone on Windows, Linux, or any CI/CD system can trigger iOS builds and publish to TestFlight.

Skip Local Environment Setup

No need to install Xcode, Android Studio, or manage SDK versions. Capgo Build handles all native tooling - you just run the CLI command.

Centralized Credentials

Store your certificates and keystores in your CI/CD secrets once. Any team member can trigger builds without needing signing credentials on their local machine.

Works With Any CI/CD

A single CLI command integrates with any pipeline. GitHub Actions, GitLab CI, Jenkins - trigger builds as part of your existing workflow.

Real-Time Build Logs

Watch your build progress live in your terminal. Logs stream via Server-Sent Events so you can debug issues instantly as they happen.

Direct Store Submission

Signed apps upload directly to App Store Connect and Google Play. No manual steps between build completion and store submission.

How It Works

When you run the build command:

Upload - The CLI zips only what’s needed (native platform folder + native dependencies) and uploads to secure cloud storage
Build - Your app compiles on dedicated infrastructure using Fastlane
Sign - Certificates and keystores are applied (they exist only in memory during the build)
Submit - Signed apps are uploaded directly to App Store Connect or Google Play
Cleanup - All build artifacts and credentials are automatically deleted

Your source code stays on your machine. Only the platform-specific native code is uploaded.

Security Model

Capgo Build is designed with zero credential storage:

Runtime-only credentials - Certificates and keystores are never stored in Capgo. They are uploaded and removed immediately after the build finishes.
Ephemeral environments - Each build runs in isolation and is destroyed after completion
No log storage - Build logs stream to your terminal only, never stored on Capgo servers
Minimal upload - Only the native platform you request is uploaded, not your full codebase. See exactly what gets uploaded

Pricing

Build time is the only cost:

Build minutes are included in your Capgo plan
Extra minutes available via credit system
iOS builds run on Mac Mini M4 (2x cost multiplier due to hardware costs)
Android builds run in Docker containers (1x cost)
No storage fees
