Before you pay for SimilarWeb
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: a single tier at Free. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
SimilarWeb runs on web, browser extension, and is published by SimilarWeb Ltd of Tel Aviv, Israel. The full record is on the SimilarWeb review, and the rest of the category is under best browser extensions tools.
