Engineering Blog

We build some of the world's most popular and complex apps and technologies. Read about our infrastructure, tools, and techniques.

Facebook Open Source

We open source a lot of the code we use to run Facebook. Fork, checkout and enjoy - and welcome to our community.

Events & Conferences

We attend and host industry events around the world, meeting communities and sharing what we've learned.


Connecting everyone, understanding the world, and building the knowledge economy are huge technical challenges. Engineers at Facebook move fast and push code up to twice a day to build infrastructure and products that provide global, real-time, and interconnected services for the 1.2 billion people who visit Facebook every month.

The mission of this site is to share our experiences with the unprecedented scaling challenges we face, to talk about our open source tools and technologies, and to help learn from - and solve important problems together with - the broader technology community.
