An architecture overview of the Evarx platform

Evarx is opinionated about workflow ergonomics and unopinionated about everything else. This piece walks through the technical seams between our four layers and explains why each is independently swappable.

We discuss the engine routing layer (LiteLLM-based), the data plane (Qdrant + Postgres hybrid), the workflow runtime (deterministic-first, with retries and observability built in), and the deployment shapes that span SaaS to air-gapped.

Reading this should leave a senior engineer comfortable explaining the system to their security team in one meeting.
