    OpenMCT is great if ALL you want is to do is look at Telemetry. But good luck if you want to send a commamd to a vehicle. I think YAMCS is much better solution: https://github.com/yamcs/yamcs

    Yamcs has got a builder for displays, client APIs, etc. Almost everything you'll ever need.

What are some alternatives?

SurveyJS Form Library - SurveyJS Form Library is a JavaScript form rendering and validation engine that takes a JSON schema and dynamically generates interactive forms using a framework-independent core. It runs entirely on the client, handling UI rendering, conditional logic, and validation, while giving you full control over data storage and submission on your backend. The same form model can be rendered through dedicated, natively supported packages for React, Angular, Vue, or vanilla JavaScript without changing the schema. In practice, you define forms as JSON, pass them to the library, and handle submission events to persist or process the results wherever you choose.
