Flightradar24 Tech Stack

Real-time flight tracking platform with 50,000+ crowd-sourced receivers

Airlines and Aviation Stockholm, Stockholm 51–200 employees Founded 2006 Privately Held

Flightradar24 operates a global aircraft-tracking network fed by 50,000+ private ADS-B receivers and processes 250,000+ flights daily, reaching 5+ million unique users. The tech stack is heavily Apple-native (Swift, UIKit, SwiftUI) on the consumer side and cloud-first on the backend (AWS EKS, Kafka, PostgreSQL, Redis), with active project focus on infrastructure-as-code and real-time telemetry pipelines. Pain points around scaling cloud infrastructure and deployment speed align with their engineering-focused hiring (senior engineers in Sweden), suggesting they're optimizing for operational velocity rather than feature growth.
