goharbor/harbor
An open source trusted cloud native registry project that stores, signs, and scans content.
What it does
Harbor is a secure storage system for software container images — think of containers as standardized packages that hold everything an app needs to run. It lets organizations store, organize, and verify these packages internally, with built-in security scanning, user permissions, and audit trails to ensure only trusted software gets deployed.
Why it matters for PMs
For any company shipping software with modern cloud infrastructure, controlling where and how software packages are stored is a critical security and compliance concern — Harbor gives teams that control without relying on third-party services like Docker Hub. With nearly 28,000 stars and backing from the Cloud Native Computing Foundation (the same foundation behind Kubernetes), this is a mature, widely-adopted solution in a space where enterprise spending is growing rapidly.
