There are no commercially available HUDs for SwCPoker, CoinPoker, or Nitrobetting Poker, so you're out of luck if you seek a sophisticated HUD-and-tracker package for use at these sites.
SwCPoker hand histories are reportedly written in a format very similar to PokerStars, and several players have reported success by making a few manual tweaks to the files and then importing them into their tracker program of choice. There's also a Blockchain Poker HUD available from rainbowflop.com, although this is a third-party site, and we make no representations or warranties about the reputability or functionality of this app.
