Building an open source payments switch
summary
An open source payments switch that unifies multiple processors into one API and acts as an orchestrator rather than a processor, implemented in Rust backend and designed for low memory (≈300 MB) and fast processing (30 ms latency). Components include open telemetry, Prometheus and Grafana for observability, Redis as the default pluggable KV store, Kubernetes Helm one‑click deployments and a secure web checkout. Repo has 5k stars in 10 months and backend, deployment and merchant dashboard are already open sourced.
