There was some celebration in our office yesterday as the total number of concurrent network connections to our servers topped one million for the first time. This is a much bigger milestone than simply one million total users; it means that at this very moment there are one million users active on Firebase-powered apps.

We’ve Grown Up

Firebase is no longer the scrappy little startup you might remember from our launch more than two years ago. We’ve grown up. More than 83,000 developers have created over 100,000 applications using our platform. Our servers handle 24,000,000 user sessions every day, and in the last month we’ve seen traffic from over 50,000,000 unique IP addresses (over 1% of the IPv4 address space!). Our customer list now includes large companies like Google, Yahoo, and Citrix, as well as up-and-coming startups like Instacart,, and Invision.

Our team has grown as well. One year ago, there were seven of us. Today, there are 24 (plus an intern), including new folks hailing from great companies like Google, Microsoft, and Salesforce. We’ve even welcomed our first PhD to the team.

The Future

The last couple years have been a whirlwind, but we’re far more excited about what’s coming next. Nearly every part of our product has new features currently under heavy development. In fact, most of the work we’ve done over the last year has been on features that have yet to be announced. Expect big upgrades to our core API, mobile support, security API, tooling, educational resources, and framework integrations in the near future.

Mobile is an especially bright spot for us. Our sync-based API is especially powerful on mobile devices where network connections are spotty or absent. As a result, Android and iOS are now our fastest growing platforms, and we’re putting a ton of resources into improving our mobile featureset.

Thank You!

None of this would have been possible without a ton of community support. Thank you for your help, whether that was providing API feedback, contributing to our open source projects, answering questions on our Google Groups, or simply telling a friend about our service.

We’d invite you all by our office so we could thank you in-person, but we know most of you are not in San Francisco. So instead, if you’d like us to send you some delicious Firebase Hot Sauce and other swag, shoot us an email and we’ll hook you up. Or, if you are in fact in San Francisco, you’re welcome to come by for office hours any Friday.

Thanks again, and we look forward to updating you again at 10,000,000 concurrents!
