Hi! Pipecat maintainer here. There is no Windows restriction for Pipecat, in general. The DailyTransport does not support Windows, but works on WSL. Though, you don't have to use the DailyTransport. Pipecat has interchangeable transport support. You can do all of your testing on a free, P2P WebRTC transport (SmallWebRTCTransport, based on aiortc) without system restrictions.
Reach out on Discord if you have any challenges.
