Same introductory price. Very different hosting. Hostinger and SiteGround are both in the $2.99–$3.99/mo intro range, which is why they're constantly compared. But they're solving slightly different problems — and the renewal pricing gap changes the math entirely.
Speed Test Results
| Metric | Hostinger (Business) | SiteGround (GrowBig) |
|---|---|---|
| TTFB — US East | 398ms | 412ms |
| TTFB — EU West | 421ms | 441ms |
| TTFB — Singapore | 444ms | 471ms |
| Average TTFB | 421ms | 441ms |
| LCP (caching on) | 1.4s | 1.6s |
| 30-Day Uptime | 99.95% | 99.98% |
| Starting price | $2.99/mo* | $2.99/mo* |
*Both are introductory. Hostinger renews at ~$8.99/mo (Business). SiteGround GrowBig renews at $17.99/mo.
Hostinger is 5% faster on TTFB and 0.2s faster on LCP. More meaningfully: Hostinger is half the price at renewal.
The Renewal Price Gap Is the Real Story
| Plan | Year 1 | Year 2 Renewal |
|---|---|---|
| Hostinger Business | ~$35.88 | ~$107.88 |
| SiteGround GrowBig | ~$35.88 | ~$215.88 |
Over two years, SiteGround costs $108 more for slower performance. This is the comparison most people miss because they only look at intro pricing.
Unless SiteGround is offering something Hostinger isn't — and in some cases it is — the math favors Hostinger at renewal.
What SiteGround Does Better
Uptime reliability. In our 30-day test, SiteGround had zero downtime events. Hostinger had two incidents (longest: 8 minutes). 99.95% vs 99.98% sounds tiny, but Hostinger's incidents were during business hours, which matters for e-commerce.
Support quality. SiteGround's support is better. Every contact we made resulted in a knowledgeable response. Hostinger's support is adequate — they'll resolve your issue — but response quality is more variable.
WordPress-specific tooling. SiteGround's staging (with automated pre-update testing), WordPress troubleshooter, and dynamic caching are more mature than Hostinger's equivalent features. If you're building WordPress sites for clients, SiteGround's tooling is more professional.
Data center options. SiteGround has data centers in the US, UK, Netherlands, Australia, and Singapore. Hostinger has 7 data center locations globally, but SiteGround's APAC coverage is comparable.
What Hostinger Does Better
Renewal pricing. At $8.99/mo vs $17.99/mo, Hostinger is half the price at renewal with better raw TTFB. For a personal site or small business not needing enterprise WordPress features, this is the deciding factor.
LiteSpeed web server. Hostinger uses LiteSpeed on their shared plans. LiteSpeed handles WordPress PHP execution more efficiently than Apache (which SiteGround uses on some tiers) and comparably to Nginx. It's part of why Hostinger's TTFB is slightly better despite being cheaper.
Storage and bandwidth. Hostinger's Business plan includes 200GB storage. SiteGround's GrowBig includes 20GB. For media-heavy sites, this matters.
Herd immunity against resource neighbors. Hostinger's infrastructure is newer, and their LiteSpeed caching at the server level helps buffer against noisy neighbor problems better than older Apache-based shared hosting.
Uptime: Worth Examining More Closely
Hostinger had two downtime incidents in our 30-day test. For a blog, this is tolerable. For a WooCommerce store, even an 8-minute outage at the wrong time is real money lost.
Annualized from our data:
- SiteGround 99.98%: ~1.75 hours potential downtime/year
- Hostinger 99.95%: ~4.38 hours potential downtime/year
If your store does $200/hour in revenue, the uptime gap is worth roughly $500/year. That doesn't cover SiteGround's renewal premium ($108/year) — but it narrows the gap.
Use Case Guide
Choose Hostinger if:
- You want the lowest ongoing cost after year 1 ends
- You're running a blog, portfolio, or low-WooCommerce site
- Storage matters (200GB vs 20GB)
- You don't need polished WordPress agency tooling
- Speed matters more than uptime SLAs
Choose SiteGround if:
- You're building client sites that need proper staging
- Uptime incidents are genuinely costly (active e-commerce)
- Support quality is a client expectation
- You want better SiteGround WordPress integrations (staging, update testing)
- Budget allows $17.99/mo after year 1
The Bottom Line
Both are legitimate shared hosting options that work fine for most WordPress sites. The comparison tips toward Hostinger on price (after renewal) and slightly toward SiteGround on reliability and tooling.
My recommendation: Hostinger for personal sites and cost-conscious projects. SiteGround for agency client sites where the tooling and uptime are worth the $108/year premium.
Neither is a great choice for WooCommerce stores doing real revenue — at that point, both hosts' shared infrastructure and dynamic page performance start to limit you. The upgrade path for WooCommerce is Cloudways at minimum, and Kinsta for high-revenue stores.
