#### Extensions

Docker Hub offers extensions for Docker Desktop, which enhance its core
functionality. These extensions are purpose-built to streamline the software
development lifecycle. Extensions provide tools for:

- System optimization and monitoring: Manage resources and optimize Docker
  Desktop’s performance.
- Container management: Simplify container deployment and monitoring.
- Database management: Facilitate efficient database operations within
  containers.
- Kubernetes and cloud integration: Bridge local environments with cloud-native
  and Kubernetes workflows.
- Visualization tools: Gain insights into container resource usage through
  graphical representations.

Extensions help developers and teams create a more efficient and unified
workflow by reducing context switching and bringing essential tools into Docker
Desktop's interface.

Extensions](/manuals/extensions/_index.md).
