We want to share our travel hack with you and save you money

No, we aren’t talking about budget hotels or shared hostels here. We want you to get the same quality and comfort, but for less. How? The same hotel can have very different prices depending on where you book it. Platforms charge hotels up to 20% in commission, and that cost usually ends up in the price you pay.
That’s why we built Directo, a free chrome extension that automatically compares prices while you browse and shows you the cheapest option available, including exclusive Directo Deals.
