Are the ions that flow from the cathode to the anode through the salt bridge cations or anions?

So in a salt bridge, cations flow toward the cathode to replace the cations that are being picked up at the electrode; anions flow toward the anode to balance the positive charge of the cations that are released from the electrode.

Both! For example, a common material for salt bridges is KCl. The K+ ions dissociate into the cation end, and the Cl- ions dissociate into the anion end to counter charge buildup.
