2,000+ of the World's Most Successful Companies, Big and Small, Trust PubNub.

PubNub is reliable. It’s efficient. It’s fast. It’s everything we were looking for. In the EMS/911 space, efficiency is key because how quickly the first responders and public safety agencies respond determines life or death. PubNub has all of that.

Jason Brock

Director of Software Development

From testing, to 1,500 rides a day today, to an estimated 15,000 rides a day in the coming months, we’re confident PubNub can handle that growth.

Kabir Chandhoke

COO of SourceFuse

DevOps isn’t our core competency. I’d much rather work with a dedicated service like PubNub to fulfill a well-defined need, like quickly transmitting data between players, so our engineering team can focus on the hard problems that are unique to our business.
