The Concorde was the safest plane ever. It flew for 27 years with just 1 accident. And that accident wasn't Concorde's fault. Another plane dropped metal on the runway, and Concorde ran over the metal and got damaged right before takeoff.
There are individual passenger aircraft that flew more hours and cycles than the entire Concorde production run without incident. The accident where running over a piece of metal on a runway during takeoff resulted in a raging inferno and ultimately the deaths of everyone on board wasn't the first time Concorde's unusually-prone-to-failure tyres had punctured a fuel tank when they exploded, or something likely to happen if a different aircraft ran over the same piece of metal. Separately, it also had two spontaneous in-flight structural failures of the rudder. All this in a production run of 14 aircraft that spent most of their life on the ground.
Considering it was a complete novelty designed in the 1970s it did OK, but I don't think there are many airframes its safety record compares favourably with.
