Overview
I ran my business sites on SiteGround for three years before switching to Kinsta. Both hosted WordPress sites for venue partners and the SkyYield marketing site. The switch wasn't because SiteGround was bad -- it wasn't. It was because Kinsta's performance difference was measurable and the support experience was noticeably better.Kinsta is managed WordPress hosting built on Google Cloud Platform. Premium pricing, premium performance, premium support. Every site gets its own isolated container, automatic daily backups, staging environments, and a CDN.
SiteGround is shared hosting that punches above its weight. Good performance for the price, solid uptime, decent support, and WordPress-specific features like auto-updates and caching.
Performance: Kinsta Wins
This is the biggest difference and the reason I switched.Kinsta's infrastructure: Each site runs in its own isolated LXD container on Google Cloud Platform. You get dedicated resources -- no other site on the server can affect your performance. Google's network (one of the fastest in the world) handles the routing. The built-in Cloudflare CDN serves assets from 260+ global edge locations.
SiteGround's infrastructure: Shared hosting on Google Cloud (they migrated a few years ago). Performance is good for shared hosting, but you're sharing server resources with other accounts. Their SuperCacher helps, but under load you'll feel the difference.
Real-world difference: My SkyYield marketing site loaded in 1.2 seconds on SiteGround. On Kinsta, same site, same content: 0.6 seconds. The venue partner sites showed similar improvements. For sites where page speed affects SEO rankings and user experience, that difference matters.
Uptime: Both are reliable. Kinsta guarantees 99.9% uptime with an SLA. SiteGround guarantees 99.9% as well. In practice, I experienced one brief outage on SiteGround in three years and zero on Kinsta in two years.
Pricing: SiteGround Wins
This is where SiteGround has a clear advantage.| Plan | Kinsta | SiteGround |
|---|---|---|
| Entry | $35/mo (1 site, 25k visits) | $3/mo (1 site, 10k visits) |
| Mid-tier | $70/mo (2 sites, 50k visits) | $5/mo (unlimited sites, 100k visits) |
| Premium | $115/mo (5 sites, 100k visits) | $8/mo (unlimited sites, 400k visits) |
Important caveat: SiteGround's promotional pricing jumps significantly on renewal. The $5/mo GrowBig plan renews at $25/mo. Kinsta's pricing stays the same. Still cheaper, but the gap narrows.
The value question: Is Kinsta worth 3-10x more than SiteGround? For a marketing site where page speed directly affects lead generation and SEO rankings -- yes. For simple informational venue pages that get a few hundred visits per month -- probably not.
Support: Kinsta Wins
Kinsta's support is the best I've experienced in WordPress hosting. Every conversation starts with a knowledgeable WordPress engineer, not a first-tier script reader. Average response time is under 2 minutes via live chat. They proactively monitor your site and will reach out if they detect performance issues. SiteGround's support is good by shared hosting standards. You'll talk to knowledgeable agents who can solve most WordPress issues. But the response time is slower (5-15 minutes typical), and complex problems sometimes require escalation. For operators managing multiple sites who don't want to troubleshoot hosting issues themselves, Kinsta's support quality justifies a significant portion of the premium.Features Comparison

Multi-Location Considerations
If you're hosting separate WordPress sites for each venue location:Kinsta approach: Each site gets its own container with guaranteed resources. Performance is consistent regardless of how many sites you're running. But the cost scales per site -- 10 venue sites on Kinsta's Business 1 plan runs $115/mo.
SiteGround approach: All sites share resources on one account. Performance is good but variable under load. The cost is flat -- unlimited sites on GrowBig at $5-25/mo (promo vs renewal).
My recommendation: Use Kinsta for your primary business site (the one driving leads and revenue) and SiteGround for simple venue informational pages. That gives you premium performance where it matters and budget hosting where it doesn't.
Who Should Use Each
Choose Kinsta if:
- Page speed directly affects your revenue (SEO, lead gen)
- You want premium support that solves problems fast
- You need staging environments and APM tools
- You're hosting 1-5 high-value business sites
- Uptime and performance SLAs matter to your operation
- You don't want to troubleshoot hosting issues yourself
Choose SiteGround if:
- Budget is a primary constraint
- You're hosting many simple informational sites
- Your sites get moderate traffic (under 100k visits/mo)
- You're comfortable with some self-troubleshooting
- You want unlimited sites on one plan
- You're starting out and want low-risk hosting
Final Verdict
For operators:
Kinsta: 4.3 / 5
SiteGround: 4.0 / 5
Kinsta is the better hosting platform. SiteGround is the better value. For operators, use Kinsta for the sites that drive revenue and SiteGround for everything else. Don't overpay for hosting that doesn't need to be fast, but don't underpay for hosting that does.
