Backstage. An open platform for building developer portals
Spotify’s internal version of Backstage is the central nervous system for all our infrastructure. It’s what our 1,600+ engineers use every day to manage 14,000+ software components. We open sourced the platform in 2020, so that any organization could build their own turbocharged developer portal. Backstage is a project in the CNCF Sandbox.
