## How to Build a Product Like GitLab

You do not need GitLab's full stack to launch. A lean, modern stack (Next.js, Node.js, a managed database) covers the core capabilities; adopt heavier infrastructure only as you scale. UniqueSide builds production-ready MVPs on stacks like this in 15 days, from $8,000.
