Gorilla WebSocket compared with other packages

	gorilla	go.net
Protocol support	RFC 6455	RFC 6455
Limit size of received message	Yes	No
Send pings and receive pongs	Yes	No
Send close message	Yes	No
Read message using io.Reader	Yes	No, see note
Write message using io.WriteCloser	Yes	No, see note
Encode, decode JSON message	Yes	Yes

Note: The go.net io.Reader and io.Writer operate across WebSocket message boundaries. Read returns when the input buffer is full or a message boundary is encountered, Each call to Write sends a message. The Gorilla io.Reader and io.WriteCloser operate on a single WebSocket message.
