Tech-chasing is possible on platforms, and may be easier to perform on them, depending on the scenario. For example, Sheik in Melee has functionally identical tech-in-place and tech in animations until a point in them by which it is too late to react in time to the differences, so usually tech-chases against her in that game rely on a read or moves that cover both those options, like Raptor Boost. Additionally, while.most characters, given a knockdown and the right position, can be tech-chased on reaction by characters that are fast enough, some cannot be. Tech-chasing is much easier to do on characters with short tech rolls (such as Bowser) than those with long tech rolls (such as King Dedede). Projectiles can also do a good job of tech-chasing when timed correctly. In particular, Fox, Sheik, Captain Falcon, Marth, Peach and Luigi rely very heavily on tech-chasing in their punish games. Since most of the high- and top-tier characters in Melee tend to have above-average mobility in general, tech-chasing becomes a very prevalent and important part of their punish games at higher levels of play. Additionally, characters with fast air speed can be good at tech-chasing, especially on platforms, like Jigglypuff, and, in Melee, characters with a long wavedash can also excel at tech-chasing, with Luigi and the Ice Climbers being solid examples. Characters with fast movement speed, like Captain Falcon, are very good at tech-chasing, as they can reach the opponent's destination faster, though those with long-reaching attacks, like Marth, can do similarly well.

Because a character's tech animations have small windows of vulnerability before ending and allowing action, it is possible to read (or, in some cases, react to) the direction of a player's tech and punish them. Tech-chasing is the act of following or predicting an opponent's tech or floor recovery in order to attack them before they can respond.
