Kinsta vs SiteGround (2026): Real Costs and Which to Pick
Kinsta’s pricing page on annual billing, October 2026. The entry plan is free for the first month, then $350 a year.
Our verdict: pick SiteGround if you run a blog, a brochure site or several small sites and want email, daily 30-day backups and phone support for the lowest bill. Pick Kinsta if one site earns real money and you want free expert migrations, free malware cleanup, edge caching and staging on every plan, with no renewal jump. The surprise comes in year two. SiteGround’s GrowBig renews at $29.99 a month, almost exactly what Kinsta’s entry plan costs on annual billing ($350 a year), so from then on you are choosing features, not price.
All prices are in US dollars before tax, checked on kinsta.com and siteground.com as of October 4, 2026. We did not buy either plan. The Kinsta side is based on its published pricing, docs and legal pages. On the SiteGround side we also installed its free Security Optimizer plugin on a test site, covered below.

Which one should you pick?
- One small blog or brochure site on a tight budget: SiteGround StartUp. It costs $35.88 for the first year and $17.99 a month after, against $30 a month for Kinsta from day one. For an even lower bill, see our Hostinger vs SiteGround comparison.
- Several small sites: SiteGround GrowBig. It hosts unlimited sites for $29.99 a month at renewal. Kinsta’s two-site WP 2 plan costs $700 a year.
- A store, membership site or busy business site: Kinsta, on Single 65k or above ($500 a year). Kinsta marks Single 65k and higher as recommended for ecommerce, and you get free staging, malware cleanup and expert chat support with no renewal jump.
- You need email on the same bill, or phone support: SiteGround. Kinsta offers neither.
- An agency with client sites: Kinsta if clients pay for premium hosting and you want user roles, APM and an unbranded WordPress admin on Agency plans. SiteGround GoGeek if you want white-label Site Tools for many small sites at a lower price.
- Big traffic spikes: Kinsta, or SiteGround Cloud (from $100 a month with optional autoscaling). SiteGround’s shared plans are not built for heavy spikes.
Pricing: year one vs year two
SiteGround: cheap first year, steep renewal
SiteGround’s WordPress hosting plans, October 2026. Each card says “Prepaid for 12 months” and shows the renewal rate.
SiteGround’s intro prices need a 12-month prepay and apply to the first invoice only. After that you pay its standard rates, which SiteGround says have applied since September 7, 2023.
SiteGround’s standard rate table for shared hosting, last updated October 2, 2026. These are the prices after the first term.
| SiteGround plan | Intro (12-month prepay) | Renewal, 12 months | Renewal, 24 months | Sites | Storage | Suggested visits |
|---|---|---|---|---|---|---|
| StartUp | $2.99/mo ($35.88) | $17.99/mo | $14.99/mo | 1 | 10GB | about 10,000 |
| GrowBig | $4.99/mo ($59.88) | $29.99/mo | $24.99/mo | Unlimited | 50GB | about 100,000 |
| GoGeek | $7.99/mo ($95.88) | $44.99/mo | $39.99/mo | Unlimited | 100GB | about 400,000 |
SiteGround calls the visitor figures “a point of reference, rather than a restriction.” The real limits are CPU seconds (300,000 a month on StartUp, 600,000 on GrowBig, 800,000 on GoGeek) and files, called inodes (200,000, 400,000 and 600,000).
Kinsta: one price, every year
Kinsta has no intro discount, so there is no renewal jump. Its terms do allow price increases with notice. Annual billing gives two months free. Each standard plan comes in a visits version and a server bandwidth version at the same price.
| Kinsta plan | Monthly | Annual | Sites | Visits per month (or bandwidth) | Storage | Daily backups kept |
|---|---|---|---|---|---|---|
| Single 35k / Single 20GB | $35 | $350 ($30/mo) | 1 | 35,000 (or 20GB) | 10GB | 14 days |
| Single 65k / Single 40GB | $50 | $500 ($42/mo) | 1 | 65,000 (or 40GB) | 10GB | 14 days |
| Single 125k / Single 65GB | $90 | $900 ($75/mo) | 1 | 125,000 (or 65GB) | 10GB | 14 days |
| WP 2 | $70 | $700 ($59/mo) | 2 | 70,000 (or 40GB) | 20GB | 14 days |
| WP 5 | $115 | $1,150 ($96/mo) | 5 | 125,000 (or 65GB) | 30GB | 14 days |
The two cheapest single-site plans run on 2 PHP threads (the processes that build uncached pages) and do not allow WordPress Multisite. Our Kinsta review lists every plan, including Agency (from $340 a month) and Enterprise (from $500 a month).
What three years cost
Assuming you start on the term shown and renew yearly at the listed price:
| Plan | Year 1 | Years 2 and 3 | 3-year total |
|---|---|---|---|
| SiteGround StartUp | $35.88 | $215.88 a year | $467.64 |
| SiteGround GrowBig | $59.88 | $359.88 a year | $779.64 |
| SiteGround GoGeek | $95.88 | $539.88 a year | $1,175.64 |
| Kinsta Single 35k (annual) | $350 | $350 a year | $1,050 |
| Kinsta Single 65k (annual) | $500 | $500 a year | $1,500 |
SiteGround wins on total cost at the small end. But look at the yearly rates from year two: GrowBig ($359.88) and Kinsta Single 35k ($350) cost about the same, and GoGeek ($539.88) costs more than Kinsta Single 65k ($500). GrowBig gives you more sites, more storage and email. Kinsta gives you more management for one site.
Overages and plan limits
Two sections of Kinsta’s overages doc, October 2026: the visit overage fee and the “extreme overages” rule.
Kinsta keeps your site online when you pass a limit and bills the extra. It charges $0.50 per 1,000 extra visits, $0.50 per GB of server bandwidth, $2 per GB of disk a month and $0.05 per GB of CDN bandwidth. It emails you at 80% and 100% of a limit. If an overage equals your plan’s price or $500, whichever is less, Kinsta may ask for payment right away, require an upgrade or limit access. Kinsta counts each unique IP address in 24 hours as one visit, so bots can add up.
SiteGround’s shared plans list no overage fees. They cap CPU seconds and files instead, and SiteGround’s terms let it step in if you exceed a plan’s limits, so a busy site hits a ceiling rather than a bigger invoice. If you outgrow GoGeek, the next step is SiteGround Cloud.
Where SiteGround Cloud fits
SiteGround’s Cloud plans, billed monthly, October 2026.
If you want SiteGround at Kinsta-like prices, compare Kinsta with SiteGround Cloud, not shared hosting. Cloud starts at $100 a month for 4 CPU cores, 8GB of memory and 40GB of SSD, with unlimited sites, a dedicated IP, free email and optional autoscaling. You get fixed resources for many sites. Kinsta charges per site and per visit, with more management built in. The Cloud refund window is 14 days, not 30.
Features compared
| Feature | Kinsta | SiteGround |
|---|---|---|
| Migrations | Free, unlimited, done by Kinsta’s team | Free Migrator plugin you run yourself; a free site transfer is advertised for a limited time |
| Backups | Daily, 14 days; up to 5 manual; one downloadable ZIP a week | Daily, 30 days, stored in another location; on-demand from GrowBig |
| Staging | Free on every plan (premium staging $20/mo) | GrowBig and GoGeek; Git on GoGeek |
| Core and plugin updates | Manual or bulk in MyKinsta; automatic plugin and theme updates with visual checks and rollback cost $3/mo per environment | Managed auto-updates for WordPress and plugins, with scheduling, included |
| Caching | Server caching plus Cloudflare edge caching of full pages | NGINX static and dynamic caching (SuperCacher), Memcached |
| Performance monitoring | Built-in APM tool | None built in |
| Not offered | Unlimited accounts, webmail | |
| Team access | Unlimited users with roles | Collaborators with their own Client Area |
| AI | AI assistant in support chat | Free AI Agent for WordPress with 20,000 tokens a month |
Two more Kinsta details are worth knowing. Kinsta now offers automatic plugin updates, but as a paid add-on. It is free for 31 days, and free during the first month on Single 35k and WP 2. And Kinsta’s visit overage is $0.50 per 1,000 visits.
SiteGround’s AI Agent runs through a plugin. As of October 2026 that plugin averages about 1.6 out of 5 stars on WordPress.org from 97 ratings, many from people who said it appeared on their sites unasked. Check your plugin list after moving in.
Security, plus a hands-on look at SiteGround’s free plugin
Both hosts run a firewall and DDoS protection. The difference is what happens after a hack. Kinsta cleans malware for free, during migration and for as long as you host there. SiteGround sells malware scanning as a Site Scanner add-on, and its one-click cleanup is in the Premium tier. Its help page says hard cases may cost an extra cleanup fee.
Kinsta has no plugin you can try. SiteGround’s Security Optimizer is free on WordPress.org (version 1.6.8, 1 million+ active installs, 4.5 out of 5 from 157 ratings), so we put it on a test install: WordPress 7.1.2, PHP 8.3 and Apache in Docker, with a few sample posts and pages.
Security Optimizer 1.6.8 on a fresh test install, October 2026, right after activation.
What we saw:
- No setup wizard. On activation it switched on most protections by itself: locked system folders, hid the WordPress version, disabled the plugin and theme editor, disabled XML-RPC, added XSS headers, blocked common usernames and limited logins to 5 wrong passwords.
- One switch needed a second click. We activated the plugin from WP-CLI (WordPress’s command-line tool). The XML-RPC switch showed as on, but xmlrpc.php still accepted a login. Turning the switch off and on in the plugin screen wrote the rule, and after that xmlrpc.php returned 403 Forbidden.
- The folder lock worked. A request for a PHP file in the uploads folder got 403 Forbidden. Turning off feeds made /feed/ return the home page instead of RSS, and the readme.html option removed that file.
- Don’t rely on the login limit alone. After the fifth wrong password, the login page showed “You don’t have access to this page.” Treat that as one layer, not full protection: use a strong password and turn on two-factor login (it supports Google Authenticator) as well.
- Post-hack tools are quick. “Reinstall All Free Plugins” ran in about one second with no confirmation step and reinstalled Akismet from WordPress.org. “Force Password Reset” and “Log out All Users” sit on the same screen.
- Light upselling. The only pitch was one “special deal on premium hosting” box on the plugin’s dashboard. We saw no notices elsewhere in the admin area.
The Post-hack Actions screen on our test install after “Reinstall All Free Plugins”, October 2026.
Security Optimizer is a useful free hardening plugin on any host. It does not replace a malware cleanup service, which is where Kinsta’s free hack fix matters.
Speed: what we could measure
We could not benchmark either host’s servers without buying plans, so we measured public pages only. On October 4, 2026, from one location in the US, we timed each vendor’s own pages with curl (median of 10 requests).
| Page | Kinsta | SiteGround |
|---|---|---|
| Home page | 308 ms | 428 ms |
| WordPress hosting pricing page | 233 ms | 425 ms |
| Blog home | 281 ms | 276 ms |
Kinsta’s pages came through Cloudflare with a Kinsta cache hit, SiteGround’s through a Google Cloud load balancer. These numbers say little about a small site on either host. Each company also publishes its own claims: Kinsta says edge caching cut time to first byte by an average of 48.6% in its testing, and SiteGround says WordPress sites moved to it in the first half of 2025 loaded 78% faster on average. Treat both as marketing.
The caching differences are real, though. Kinsta caches full HTML pages at Cloudflare’s edge on every plan. SiteGround caches full pages on its own servers by default, but its free CDN caches only static files; full-page caching at the CDN edge needs its Premium CDN. SiteGround’s caching plugin also only works fully on its own servers. When we tried its free Speed Optimizer plugin on a test install for our Hostinger vs SiteGround comparison, Dynamic Caching and the image tools only showed an “Available on SiteGround environment” message.
Dashboards: MyKinsta vs Site Tools
Neither host uses cPanel. MyKinsta puts staging, backups, caching, the APM tool, analytics, DNS, bulk plugin updates across sites and a file manager in one place, and since January 2026 it requires two-factor login. Site Tools gives each site its own panel for files, email, DNS, databases, backups, caching and the CDN, and GoGeek adds white-label access for clients. We could not log in to either without buying a plan, so this is based on each vendor’s published screens and docs. If you live in the dashboard every day, MyKinsta has more developer and multi-site tools. If you also need email and DNS for small sites, Site Tools covers more.
Support, uptime guarantee and refunds
| Kinsta | SiteGround | |
|---|---|---|
| Channels | 24/7 chat in 8 languages, AI assistant; no phone for support | AI help center first, then 24/7 human chat, tickets and phone |
| Vendor claims | Median first response under 2 minutes | Over 90% of questions solved on first contact |
| Uptime guarantee | 99.9%; credits start after 43 minutes of downtime a month | 99.9% a month; 5% of the month’s fee as extra hosting time |
| Refunds | 30 days, first-time customers; overages not refunded | 30 days on shared plans, 14 on Cloud |
Neither uptime guarantee pays much. On Kinsta’s annual entry plan, a three-hour outage earns about $5.83 in credit.
Infrastructure and data centers
SiteGround runs on Google Cloud in 11 locations: Iowa, Virginia, Dallas and Los Angeles in the US, plus London, Madrid, the Netherlands, Frankfurt, Paris, Sydney and Singapore. Kinsta is moving its WordPress hosting from Google Cloud to Oracle Cloud Infrastructure (OCI) and lists 30 data centers, including four in the US. Kinsta’s docs say most sites are offline for under a minute during the move, but the IP address can change and you cannot opt out. Our Kinsta review covers the move in detail.

FAQ
Is Kinsta better than SiteGround?
For a site that earns money, usually yes. Kinsta includes free expert migrations, free malware cleanup, edge caching, staging on every plan and no renewal jump. For small sites, SiteGround is better value: it includes email, daily backups kept 30 days and phone support, and its first year costs a fraction of Kinsta’s.
Why does Kinsta cost so much more than SiteGround?
It mostly does not after year one. SiteGround’s $2.99 is a first-year discount. GrowBig renews at $29.99 a month, about the same as Kinsta’s $350-a-year entry plan. Kinsta charges per site and per visit and puts more management into each plan, while SiteGround gives more sites and storage for the money.
Does Kinsta or SiteGround update plugins automatically?
SiteGround includes managed automatic updates for WordPress and plugins on its shared plans, and you can schedule or skip versions. Kinsta lets you update plugins manually or in bulk for free. Its automatic updates, with visual checks and rollback, cost $3 a month per environment after a 31-day trial.
Does either host include email?
SiteGround does, with unlimited email accounts and webmail on every plan. Kinsta does not provide email, so you need a separate service such as Google Workspace or Microsoft 365.
Is WordPress.org’s recommended host Kinsta or SiteGround?
Neither. As of October 2026, WordPress.org’s hosting page lists Pressable, Bluehost and Hostinger. SiteGround used to be on that list but no longer is.
Final verdict
Pick SiteGround for small sites where email, 30-day backups and phone support matter more than premium extras, and budget for the renewal from year two. GrowBig is the plan to watch, because from year two it costs about the same as Kinsta’s entry plan. Pick Kinsta when one site carries your business and you want migrations, malware cleanup, staging and expert support handled for you at a price that stays the same each year. Keep an eye on its visit limits and add-on costs.
