SiteGround vs Kinsta vs Pressillion: Hosting Comparison for WordPress Agencies
Choosing between SiteGround and Kinsta for WordPress hosting?
If you’re an agency managing 10 to 1,000+ client websites, the stakes are high. Your hosting platform needs to balance raw performance with flexibility, transparent pricing, scalable workflows, and responsive support.
In this guide, we compare SiteGround and Kinsta across all key areas for agencies – and show why Pressillion is becoming the go-to choice for performance-focused, agency-first WordPress hosting.
Performance: SiteGround vs Kinsta Speed & Stability
SiteGround uses a mix of Apache and NGINX, which can introduce performance tradeoffs under traffic surges. Independent benchmarks found that while SiteGround performs acceptably for small to medium sites, it doesn’t scale well under load.
Kinsta runs NGINX on Google Cloud Platform’s C2 machines, offering high-performance compute but at a steeper price. It also restricts control over server-level configurations.
Pressillion, by contrast, gives you a choice of DO, Vultr, or Linode configured with NGINX reverse proxy, Redis object caching, and Docker containerization to isolate and scale workloads efficiently – all pre-optimized out of the box.
Developer Workflows: Balancing Power with Usability
Both Kinsta and SiteGround offer basic developer tools like WP-CLI and SSH, though SiteGround limits some tools to higher plans.
Pressillion includes SSH, WP-CLI, and staging by default for every environment – no upgrade required. Workflow defaults are preconfigured for common use cases like WooCommerce and multisite.
WooCommerce Hosting: Which Platform Handles Stores Better?
SiteGround supports WooCommerce but lacks deep performance optimization. Kinsta provides better support but charges more for high-traffic Woo stores.
Pressillion is optimized for WooCommerce use by default, with Redis object caching enabled and the option to segment high-concurrency stores across containers.
Pricing & Cost Transparency
- SiteGround: Starts at £11.99/month, with renewal hikes up to £29.99/month. Limited staging and tools on base plans.
- Kinsta: Starts at £25/month, with Redis or reverse proxy caching as paid add-ons. Pricing is linear by site count. Kinsta feature overview from BloggingWizard
- Pressillion: Starts at £8/month, including reverse proxy, Redis, SSL, and staging at all levels. No hidden jumps or plan restrictions.
Agency Scaling: Managing 5-500+ Sites
SiteGround’s backend (Site Tools) lacks modern batch operations or large-scale multisite handling. Kinsta’s MyKinsta platform provides better dashboards but lacks bulk action tools.
Pressillion is built with high-volume agencies in mind – every member can scale with flexible per-site isolation and an agency dashboard focused on managing clients.
Support Experience: When You Need Help
SiteGround support is available 24/7 but often rated as slower and more scripted. Trustpilot feedback often notes delays.
Kinsta has fast support – often within minutes – but does not allow direct developer contact. Kinsta user experiences
Pressillion support is engineer-led. Clients can livechat or priority email for direct access to the people maintaining the platform.
Migration and Onboarding: Making the Switch Seamless
SiteGround uses a basic plugin for migration, but struggles with larger sites or multisite.
Kinsta offers guided migration but charges for complex setups. WooCommerce or membership-based sites may be excluded from free migrations. Detailed guide
Pressillion handles all site migrations manually, free of charge, and specializes in larger WooCommerce, multisite, and link network setups.
