Building mobile apps that need document scanning is often a challenge:
You want high performance.
You need cross-platform support (Android & iOS).
And you don’t want to reinvent the wheel every time.
That’s why I created [BelZSpeedScan][1]
, an open-source Kotlin Multiplatform (KMP) library that brings fast, clean and reliable document scanning to your apps with minimal setup.

Why BelZSpeedScan?
Most scanning solutions are either locked to one platform, closed-source, or too heavy to integrate. BelZSpeedScan is designed with developers in mind:
✅ Cross-platform – Works on Android and iOS with a shared API.
✅ Fast & lightweight – Optimized camera preview and capture pipeline.
✅ Clean architecture – Built with separation of concerns, easy to extend.
✅ Open source – MIT licensed and community-driven.
Installation
Add the dependency in your build.gradle.kts (publish on MavenCentral):
implementation("io.github.ismoy:belzspeedscan:1.0.12")
Don’t forget to configure iOS-specific permissions in your Info.plist file:
<key>NSCameraUsageDescription</key>
<string>We need access to the camera to scan QR.</string>
Quick Usage
Here’s how simple it is to start a camera preview and capture a scanned code:
var showScanner by remember { mutableStateOf(false) }
if (showScanner) {
BelZSpeedScanner(
onCodeScanned = { code ->}//result scan
)
}
Button(onClick = { showScanner = true }) {
Text("Scan")
}
Analytics Integration
BelZSpeedScan includes an optional analytics system designed with privacy in mind:
- Privacy-focused: No personal data is collected
- Configurable: Granular control over what data is collected
- Multi-platform: Works on both Android and iOS
- Custom Callbacks: Support for custom analytics implementations
Contribute
BelZSpeedScan is still in its early days. If you’re building apps with Kotlin Multiplatform and need fast scanning, I’d love your feedback, issues, and contributions!
I built BelZSpeedScan because I needed a reliable KMP solution for code scanning. Now I’m sharing it with the community. If you find it useful, consider comment the post and share
