Duffel provides a developer-focused API toolkit for travel companies to book flights, ground transport, and related services. The stack reveals a modern, distributed architecture (Elixir/Phoenix backend, React/Next.js frontend, Kubernetes orchestration on GCP) paired with airline connectivity through Travelport, Sabre, and Amadeus. Active projects span core API reliability, fraud detection, and new verticals—while pain points cluster around legacy airline integrations and internal process efficiency, suggesting Duffel is abstracting complexity away from customers but still wrestling with fragmentation on the airline side.
