They are similar but there are differences. Crostini are small toasts, often served as appetisers or snacks, mostly roasted or grilled in the oven, and served with a topping. Bruschetta, pronounced “brew-sket-tah” uses larger, thicker slices of bread, made from sourdough bread or a crusty Italian loaf, and grilled on a ribbed grill pan on the stove or on the barbecue. The toasts usually have char marks. In its simplest form, serve your bruschetta rubbed with a cut clove of garlic and drizzled with olive oil. There are endless possible toppings for the toasts; marinated tomatoes is one of the most popular.
