I know that the latest Solidity supports error messages in require/revert (require(stuff, "problem")).

Are there any clients that can get this message? Will I be able to see it if I execute the transaction in Parity, or Truffle, or Remix? Will it be visible on Etherscan?

EDIT: a similar question has been asked before (Custom error message in require() not showing up?). That one was about web3 not displaying the message. I know web3 doesn't support it yet, my question was about which other clients (Parity, Remix, or, maybe, just plain RPC) support it, so I believe it's not a duplicate.

Remix supports it.

in a code i am working on for require(stuff..,"player doesn't exist"); i get in the console the message: 

Reason provided by the contract "player doesn't exist"

    Do you know of any way to do this with golang and not using remix? – hextet Jul 20 '18 at 9:58

The latest Truffle supports it, plus we can get and decode the transaction trace using the Parity's replay transaction feature.
