Elsa Studio is a modular, extensible Blazor application that serves as the frontend for managing Elsa Workflows. It provides a visual workflow designer (supporting BPMN, flowcharts, state machines, and sequences via both X6 and React Flow rendering engines), workflow definition/instance management, real-time diagnostics (structured logs, console logs, OpenTelemetry traces/metrics), authentication (ElsaIdentity, OpenID Connect, external brokers), role-based security, user tasks, and platform integration. The application is built on a plugin architecture using features, widgets, and menus registered via dependency injection. It communicates with the Elsa Core backend through Refit-generated API clients and SignalR for live updates. The codebase demonstrates strong engineering practices with extensive unit and integration tests, but shows some technical drift due to dual designer engines, outdated Docker targets (.NET 7), and multiple authentication stacks that increase maintenance surface.
