Usually, brokers offer zero spread but they take a commission, and tipically number spread fee and commission are equal, so in my view, it's the same thing but a different name or term.broker sometimes offers 0 pips spread , i dont know how they make profit because by using spreads brokers only make profit.
I found my low spreads broker by researching on different forum sites and by reading several reviews.
I currently trade with FP Markets, an ASIC broker with some of the lowest spreads starting from as low as 0.0pips through the day.
