crewai in a browser, so that building a multi-agent system does not have to start with a python file.
it is a streamlit app for defining agents, tasks and crews, wiring them together, and running them with the output streaming back as it happens. you can do all of it from a script. what the app removes is the hour of boilerplate between understanding what a multi-agent system is and having one running.
a crew is a graph of agents with dependencies, and most people's first instinct is to build it as a list. the ui mostly exists to make the graph visible before you run it.
