Swell is an API development tool that specializes in streaming, websockets, sse, graphql, and restful APIs. Developers can use HTTP/2 and test both restful and nonrestful endpoints of all kinds

Swell has just had a major update! It is a streaming API dev tool that enables testing of API endpoints served over modern networking technologies including Server-Sent Events (SSE), WebSocket, and HTTP/2, and GraphQL.

Swell is in Beta but is also Open Source!

This looks awesome and it's so neat that Swell has support for GraphQL. Can't wait to try this out!

After identifying a need to test streaming technologies in a user-friendly GUI, Swell has undergone significant refactoring and embraced support for GraphQL.
