Swell is a cross-platform compatible (Mac, Linux, & Windows) desktop application and the leading API dev tool for testing and visualizing steaming TCP connections (ie WebSockets, SSEs, GraphQL subscriptions) Swell functions similarly to Postman, but with the added perks of full streaming and GraphQL support. Swell's internal structure was recently reimplemented into a hybrid architecture where all streaming capabilities are performed by the Chromium process and all unary activity is handled by the Node process.
