Example Use Cases

Digital Agencies

Agencies trust UnionStack to manage 50+ client WordPress installations without ops overhead. Automated updates, staging environments, and per-client email infrastructure mean agencies focus on design and strategy—we handle the rest.

High-Traffic Publications

Media companies publish with confidence knowing our Kubernetes infrastructure auto-scales for traffic spikes. Whether its a viral article or trending news, your WordPress site stays responsive under load.

E-Commerce & SaaS

WooCommerce shops and SaaS landing pages run fast and secure on UnionStack. Our infrastructure handles payment processing, high-volume transactions, and compliance requirements seamlessly.

Performance by Default

Typical UnionStack site metrics:

  • Page load time: <1 second (median)
  • Lighthouse score: 90+
  • Time to first byte: <100ms
