Do you know the stack?
These are the logos of some of the open-source projects we build with every day — from Docker and Proxmox to tools only a few people recognise. Can you name the project behind the mark?
Name that logo.
Ten logos, five options each round. The brand only shows once you have answered. Tip: keys 1–5 let you pick faster.

Every project here is inspectable, auditable and free of licence gates.
