A jailbreak (In most version of IOS) there's multiple jailbreak 'providers' created by different grouo of developers (most of the time). Recently the two jailbreak dominating in the IOS 13-14, are the Unc0ver jailbreak works on IOS 14.3 and below, while Taurine works on IOS 14.3 and below (older versions are called Chimera for IOS 13).

I am using only IPhones in the chart (not including IPad or IPod to the mix) and recalling from before, not all IPhones are avalible for jailbreak, here's a table where it shows what IPhones are Hardware based which can work with the Checkmate (Checkm8) Jailbreak while the Non-Hardware works for all IPhones (with the A9 Chip) as showned here:
also the Jailbreakable tab there's two diferent tags for every device support (A9 thru A14 chips) and checkmate only support (A9 thru A11 chips):
All IPhones talks about all IPhones, while Almost All IPhones Is for the Hardware based jailbreaks (A9 thru A11 chips).
