Description
In the context of operator interfaces (OPIs), EPICS has a mature ecosystem of desktop tools. In contrast, the adoption of web-based solutions remains low: existing approaches typically require desktop applications for OPI design, using the browser only at runtime, or demand JavaScript development from users. WEISS (Web EPICS Interface and Synoptic Studio) addresses this gap by providing a web-native, no-code architecture built on a modern web stack. It offers a complete in-browser environment for designing, configuring, and deploying operator interfaces without requiring programming. In addition to a graphical editor and clearly separated staging and runtime environments, WEISS provides a fast, lightweight deployment model, making selected OPIs instantly available to operators. For version control, direct integration with remote Git repositories enables commits, checkouts, and rollbacks within the same interface, reducing context switching and dependency on external clients. By removing the need for local tooling and reducing development overhead, WEISS lowers the barrier to creating and maintaining EPICS GUIs in modern web environments.
This talk showcases WEISS's current and planned features, typical use cases, and the workflow for deployment of production OPIs using the tool.
