Both make Jeopardy boards. One of them also runs the game.
JeopardyLabs calls itself "a Q/A board with a scoreboard attached", and it's a good one. Plonkus is the whole game: phone buzzers, Daily Doubles, Final Jeopardy with wagers, and scoring that keeps up. Both are free to build and play, with no ads and no signup.
