PhilBuilder vs voltbuilder

The problem Every time I needed to hand someone a quick installable build — a client, a tester, myself on a different machine — I had to either keep a full local toolchain ready (Android Studio, Flutter SDK, Visual Studio...) or spend 20 minutes reinstalling one just for a single build. So I built PhilBuilder : upload a zipped source project, pick a platform, get back an installable app. No local setup required. 🔗 Try it: https://philbuilder.netlify.app What it does You upload a .zip of your project. The tool: Auto-detects the project type (React, Vue, Flutter, React Native, Kotlin, .NET MAUI, Python, Go, Godot, and 14 others — 22 combinations total) Builds it on remote CI Gives you a download link for an APK, AAB, or Windows .exe No account needed for occasional use (3 builds/day). A free account bumps that to 10/day. How it's built The stack is intentionally simple: Frontend : a single static HTML file, no framework, no build step Backend : a Cloudflare Worker handling auth, rate limiting, and dispatching builds Build execution : GitHub Actions — one big workflow with per-language jobs (Cordova for web frameworks, Capacitor for modern web, native Gradle for Kotlin/Java, dotnet publish for MAUI, flutter build for Flutter, briefcase for Python, gomobile for Go, etc.) Storage : Cloudflare R2 for source zips and build artifacts The auto-detection logic walks the extracted zip looking for telltale files — pubspec.yaml → Flutter, *.csproj → .NET MAUI, capacitor.config.* or a @capacitor/core dependency → Capacitor, build.gradle without package.json → native Kotlin/Java, and so on — with fallbacks down to plain HTML. Some technical details Signing : for Android release builds, it can auto-generate a keystore (and let you download it afterward — losing it means you can never update your app on Play Store again, so this is clearly flagged) or accept an uploaded one. Windows builds : this is the newest addition. Flutter and .NET MAUI need windows-latest runners; Go cross-com
