⚙ Full Stack
Node.js/TypeScript backend and workflow engine, Postgres for flow/run persistence, Redis for the job queue driving flow execution.
📈 Scaling Analysis
The queue-driven execution engine (Postgres + Redis) is a sound pattern for scaling flow throughput horizontally via more worker instances, though the per-piece integration code quality varies and can become a reliability bottleneck at high flow volume.
🚀 Running on Nexlayer
App pod plus postgres and redis pods; set AP_FRONTEND_URL to the Nexlayer domain and AP_REDIS_URL to redis.pod:6379. mirror.gcr.io/library/node covers the base image; each 'piece' (integration) may need outbound network access to third-party APIs.
