Overview
TelemetryDeck is a privacy-focused analytics service built entirely on Swift infrastructure that manages data for 16 million users monthly. The company chose Swift for backend development because its compiled nature catches errors at compile time instead of runtime, making it ideal for high-performance web services.
The Breakdown
- Built on Vapor web framework - uses Swift for both frontend iOS apps and backend services, creating a unified development experience
- Runs on Kubernetes containers with Swift-native connectors - integrates with Postgres for metadata and Apache Druid for analytics data storage
- Leverages Swift’s compile-time error detection - prevents runtime failures that are common in Python, Node, or Ruby backend services
- Demonstrates Swift’s viability for large-scale server applications - proves Swift can handle enterprise-level analytics processing beyond mobile development
