Swell is a Streaming API development tool that enables developers to test API endpoints served over modern networking technologies including Server-Sent Events (SSE), WebSocket, and HTTP2.
Swell is currently in BETA
Looks great: Our organization has been needing a tool to test SSE since postman does not support yet.Cons:
UI still has some bugs....but its still beta I guess.
Our organization is in the process of developing a SSE API, but we're running into a roadblock with testing it out side of Google Chrome.Ney Z has used this product for one day.
