1. Meow is a project that aims to create modeling editors that run directly in web browsers without requiring local installation. 2. It is building projectional editors using Angular and TypeScript that allow non-technical users to create models simply and access them from anywhere. 3. Current applications include a web version of the Essential metamodeling environment, support for ECore models, and an editor for software requirements documentation in aerospace. Feedback is requested on these alpha quality tools.
