Researching a new hosting provider can be time-consuming and confusing. Basic features and factors such as pricing, number of installs, backups, etc., are generally easy to find. But when it comes time to dive into the nitty-gritty behind the scenes stuff, this is where it can get more complicated.

Most of the time you’re just needing to see if a host ticks all your boxes and would be a good fit for your business. To hopefully help make your decision a little easier, we’ve compiled all the most common technical questions about Kinsta in one place.

Many of the questions below come directly from our sales team and are sorted, for the most part, in order of most frequently asked. Click on a question below to jump directly to the answer.

How Much Faster Will My Site Be on Kinsta’s Platform?

While not universally true, nearly all sites we migrate over from other managed WordPress hosting providers run faster at Kinsta.

Check out our case study with SkyRocketWP. They came to Kinsta searching for speed for their clients, and they found that and much more. They ended up moving over 100 sites to Kinsta from WP Engine and saw on average a 49% decrease in page load times.

Or WP Buffs, who saw their page load times cut in half. Just by switching to Kinsta and activating our built-in CDN, they were also able to cut their bounce rate down by an average of 21%. If you’re looking for more in-depth load tests of our platform, we recommend checking out ReviewSignal’s annual performance benchmarks. We can proudly say that Kinsta has stood its ground in all tests against other managed WordPress hosts, and proved to be one of the best-performing companies, four years in a row!

Kinsta utilizes Google Platform and its premium tier network to ensure lightning-fast network speeds. You can choose from any of our 37 global data centers. Placing your site closer to your visitors helps decrease latency and TTFB, while ensuring lightning-fast load times. Pair that with our HTTP/3 CDN, the latest versions of PHP (including PHP 8), and our isolated container technology; we’ve got the best performance stack in the industry.

Thanks to the latest generation C2 and C3D Google Cloud servers we use a lot of clients experience up to a 200% boost in performance!

Can I Try My Site on Kinsta for 3-4 Days to See the Performance Differences Compared to My Host?

We don’t offer short-term trials, but here’s what we do have:

  • First month free: We now offer the first month free on our Single 35k and WP 2 plans, allowing you to explore all of Kinsta’s features without any upfront payment. After the first month, regular plan pricing applies.
  • 30-day money-back guarantee: On all other plans (including add-ons), we offer a 30-day money-back guarantee. If you cancel your hosting account within the first 30 days, you’ll receive a full refund—making it a risk-free way to try Kinsta!
  • No long-term contracts: You can cancel your subscription at any time without being locked into a long-term commitment.

Can I Ask for Additional Storage in Case I Need Any (or PHP Workers, Installs, Etc.)

It depends on what you need. If you need additional disk space, we have a disk space add-on which allows you to increase the storage space of your hosting plan with a few simple clicks. Need an extra 80 GB? No problem.

Another cheap and effective alternative is to offload your big files to separate storage services such as Amazon S3 or Google Cloud Storage. This is a great way to keep your hosting costs down. We have many clients that do this.

If you need additional PHP workers or WordPress installs, you will need to upgrade your hosting plan. We do have higher Single 2.5M and Single 3.15M plans available.

You can check with our sales team regarding the amount of disk space, PHP workers, and the number of installs allocated to each.

Can I Use a Caching Plugin?

Kinsta doesn’t allow caching plugins because we already have four types of cache, which are all automatically done at the software or server-level. This is controlled by our Kinsta MU plugin which is installed, by default, on all WordPress sites.

Read more about how Kinsta handles caching.

Exception: We do support WP Rocket version 3.0 and higher. Their caching functionality will automatically be disabled when running at Kinsta. This allows you to use our built-in caching solution but still utilize the other optimization features WP Rocket has to offer.

Can You Increase the Default Cache Expiration Time?

Our page cache is set to expire every 1 hour by default. However, you can also make the change yourself right from your MyKinsta dashboard. For sites that don’t change often, it can be beneficial in terms of performance to have a longer cache expiration.

How Does Kinsta Handle Caching for WooCommerce and EDD?

We have server-level caching rules already in place for popular ecommerce solutions such as WooCommerce and Easy Digital Downloads. By default, certain pages that should never be cached, such as cart, my-account, and checkout, are excluded from caching. Users automatically bypass the cache when the woocommerce_items_in_cart or edd_items_in_cart cookie are detected to ensure a smooth and in-sync checkout process.

If there is an additional section of your ecommerce site that needs to bypass the cache, you can always reach out to our support team.

Does Kinsta Offer Reseller/White Label Solutions?

We do not offer your typical reseller plan at the moment. Although, many agencies use Kinsta and sell hosting to their clients. Our multi-user permissions make this easy. We also do have white label options on our Kinsta MU plugin which is by default installed on all WordPress sites.

You can also earn passive income by referring clients to Kinsta by joining our affiliate program.

How Soon Can You Do My Migration? How Long Does It Take? Will My Site Be Down?

After signing up you’ll be able to request a free hands-off migration immediately from our MyKinsta dashboard. We’ll get in touch, discuss the details, and schedule a migration window that works best with your schedule.

We will complete your migrations as soon as possible, typically within 24 hours, but it could take up to 3 business days. You’ll be notified of your migration status by our team and you can track the status in our MyKinsta dashboard.

For even faster results, Kinsta offers Expedited Migrations, where for a fee ($49 USD), we can complete your migration within 8 hours. This option is perfect for urgent needs and comes with a refund guarantee if the migration takes longer than expected.

Moving your site to Kinsta usually won’t incur any downtime. Sites that are updated continuously, such as ecommerce (WooCommerce and Easy Digital Downloads), membership, and community sites, must be placed into maintenance mode during migration to prevent data loss. Read more about this.

Our team will notify you when they’re finished along with how to preview your site before going live.

Can We See the Performance Benefits Before Pointing DNS to Kinsta?

You definitely can test your site on Kinsta before changing the DNS. Here are a couple options.

Option 1

You can add a subdomain like test.yoursite.com, point the DNS of only the subdomain to Kinsta, and then compare it to your current site.

You will need to do a quick search and replace on your site for this to work properly. You can take a backup of your site and then use our search and replace tool to update it with your temporary subdomain.

Once you’re done testing, you can easily one-click restore your site. Depending on how often data is changing on your live site, you might simply end up doing a fresh migration after you’ve tested.

Option 2

You could also test locally from your location with Chrome DevTools by simply editing your hosts file.

Can I Run Load Tests?

There is a big difference between running a website speed test and load testing. Sometimes people confuse the two.

Website Speed Test

A website speed test typically measures PHP (which includes MySQL + PHP) response times. Or in other words, the total load time of a page. Most people use Pingdom or GTmetrix for that and look at the HTML render/wait time, and compare it with their current host. So you can set up with us and put your site on a subdomain like test.yoursite.com and then compare it to your current site on its live domain.

Load Testing

While website speed tests are allowed, load testing is prohibited on the MyKinsta platform. For more information about what testing is allowed, please refer to our Terms of Service.

Does Kinsta Provide Free Migrations?

All of our plans include unlimited free migrations. You can request a migration under Migrations in the MyKinsta dashboard.

We offer unlimited free migrations from all hosting providers including WP Engine, Flywheel, SiteGround, Pagely, Liquidweb, Pantheon, Cloudways, GoDaddy, DreamHost, Bluehost, HostGator, A2 Hosting, and tsoHost customers! Learn more about Kinsta migrations.

Can I Use My SSL Certificate Purchased From My Domain Registrar?

Yes, you definitely can. This requires regenerating the CSR and Private Key from your SSL provider or domain registrar. As each registrar is slightly different, we recommend checking their documentation or opening up a ticket with their support team. Once you have it, you can install the SSL certificate in the MyKinsta dashboard (here’s how to install the SSL certificate on WooCommerce sites).

We also offer free automatic Cloudflare SSL certificates (wildcard configurations are supported). So unless there is a reason you need your own SSL certificate, it’s much quicker and easier to use our free SSL.

Does Kinsta Support Multisite?

We support WordPress multisite installations on our Pro and higher plans. If you’re currently on our Starter plan, you’ll need to upgrade in order to utilize multisite.

Please check this article for additional notes regarding multisite setups.

Does Kinsta Have Staging for Multisite Environments?

Depending on how your multisite is setup, it may or may not work with our staging environment.

  • If it’s a subdirectory multisite (example.com, example.com/subsite1, example.com/subsite2) it will work fine with our WordPress staging environment.
  • If it’s a subdomain multisite (example.com, subsite1.example.com, subsite2.example.com) it will work fine provided the subsites don’t require HTTPS. If the subsites do require HTTPS, you will have to bypass SSL errors on staging to access the subsites. This doesn’t impact functionality in any way.
  • If it’s a domain-mapped multisite (loads different subsites at completely different domains, i.e, example.com, example1.com , example2.com) it won’t work without significant manual setup.
    • Option 1: Turn off domain mapping and go back to the standard subdirectory/subdomain setup. Do a search and replace in the database manually.
    • Option 2: Set up staging subdomains for each live domain, add all those to the staging site, and run a search and replace in the database manually.

On Staging, Can I Only Push the Database Live?

Our staging environment now includes Selective Push, which provides you with more granular control on what to push live. You can choose to push only the files, only the database, or both the files and the database from your staging environment to your live site.

Can I Add Other PHP Scripts?

While we will allow you to set up a simple non-WordPress PHP script alongside your WordPress site, we do not provide any support for non-WordPress scripts and applications.

Can I Host HTML Sites?

You can host HTML sites at Kinsta. If the default WordPress index.php isn’t found in the /public directory, our server will automatically load index.html. If you are using a different page, you will need to reach out to our support team to add a special rule on the server for this to work properly. Note: we don’t provide any additional support for non-WordPress sites.

Do My Sites Get a Dedicated IP?

No, we don’t provide dedicated IPs.

A shared IP is quite common nowadays with most hosting providers as for many configurations, there is no need for a dedicated IP address. Since we offer a free Cloudflare integration for all sites hosted on Kinsta, our shared IPs are actually Cloudflare IPs.

Our allocated Cloudflare IPs are only used for sites on our infrastructure. This means if your site is hosted on Kinsta, you won’t share an IP address with sites hosted outside Kinsta – some of which may may contain adult or spam content. Check out our in-depth post explaining the difference between dedicated IPs and shared IPs.

We do have external IPs. This is the IP address that other servers see when your site connects to another server. For example, if your site connects to a third-party payment processor like PayPal, you might need to provide PayPal with the external IP address so that they can allow the IP on their end.

What Are PHP Workers? How Do I Know How Many I Need?

PHP workers determine how many simultaneous requests your site can handle at a given time. To put it simply, each uncached request for your website is handled by a PHP Worker.

Each of the hosting plans at Kinsta includes a certain number of PHP workers. The number included is based on resource usage we have seen with clients over past couple of years. In general, sites with lots of static content – articles, static pages, blog posts – don’t need many PHP workers.

4 PHP workers are usually enough for larger sites. However, this can vary per site as each one will have its own unique set of third-party plugins, queries, dynamic content, and number of cached vs uncached responses. So in some cases, the more PHP workers the better.

See our article on everything you need to know about PHP workers at Kinsta.

Do You Have a List of Banned Plugins?

Yes, there are certain third-party plugins which we don’t allow in the Kinsta environment. In most cases, this is because they have been known to hurt performance, not work on our platform, or are simply not needed as we provide a better and easier way to do the same thing in our MyKinsta dashboard. Check out the full list of banned plugins.

Will Kinsta Host My Emails?

We don’t provide email as a part of our plans since we fully commit all of our resources to application, database, and managed WordPress hosting.

We always recommend Google Workspace, one of the world’s best email services, since it has a lot of features for a great price and allows you to use your own domain name.

Check out all the downfalls of using your hosting provider for email.

Does Kinsta Have Git Support?

We have the Git client available at Kinsta so you can SSH in and pull your own Git repo down from Github, Gitlab, Bitbucket, or any other third-party. However, we don’t yet have the feature released yet where you can just git push kinsta my_site and it automatically gets deployed.

Check out how to use Git at Kinsta.

Does Kinsta Offer Load Balanced Solutions (Multi-Location)?

At Kinsta, every site on our platform runs in a single Linux container and the site database runs as a service within the site container. We do not run multiple load-balanced instances of each site. Learn more about Kinsta’s architecture.

Can I Have More Than One Database?

No, we only allow one database per site.

Can I Add a Custom Domain with the Kinsta CDN?

This is not currently available. We are working on adding the ability to use a custom CDN URL on your site, such as cdn.yourdomain.com.

Is Kinsta SOC 2 and ISO Certified?

Yes, Kinsta is SOC 2 Type II compliant, undergoing annual security audits conducted by independent agencies like BARR to ensure the highest standards of data protection. Additionally, Kinsta holds ISO 27001, ISO 27017, and ISO 27018 certifications, which reinforce our commitment to robust cloud security and the safeguarding of personal data. These certifications demonstrate that Kinsta follows industry-leading practices to protect your data and meet strict international compliance standards.

To learn more, visit our Trust Report page for detailed information on how we maintain these compliance certifications.

Is Kinsta PCI Compliant?

Kinsta does not guarantee PCI compliance, and we are not able to audit your site to verify that you’re doing things right either. However, that doesn’t mean you can’t be PCI compliant when hosting your website with us. In fact, we have many clients who have worked with third-party auditors to pass PCI compliance scans. In many of these cases, we’ve had to make a few minor adjustments upon request, but these clients have been able to pass the audit just fine after a little fine-tuning on both our end and theirs.

Check out additional details regarding PCI compliant hosting at Kinsta.

Is Kinsta HIPAA or PHI Compliant?

Due to the complex auditing and security needed neither we nor many other managed hosting companies can guarantee HIPAA or PHI compliance.

What is Considered a WordPress Install at Kinsta?

Each Kinsta hosting plan allows one or more WordPress installs. Each install equals 1 WordPress site, which consists of its files (core files, theme files, plugin files) and a database.

The one exception to this would be if it’s a multisite. See below.

How Does Kinsta Count Multisites?

Multisite setups are considered one install each. For example, you could have one multisite with 10 subsites, this is still considered one install because all the subsites in the network share the same installation and database.

How Much CPU and RAM Does Each Plan Have?

Kinsta utilizes virtual machines in one of Google Cloud Platform’s multiple data centers. In available regions, we utilize compute-optimized (C2) virtual machines, which offer the highest per core performance (3.8 GHz) on GCP and are optimized for CPU-intensive workloads like WordPress.

On our standard plans, each live site container has access to 12 CPUs and 8 GB of RAM by default. Each staging environment on our Standard plans has access to 1 CPU and 8 GB of RAM.

Why Is Kinsta So Expensive?

To answer this, we recommend you first read through our Why Us page, where we outline a lot of the differences between us and our competition.

If you’re coming from another managed WordPress host such as WP Engine, SiteGround, or Flywheel, check out these in-depth comparisons:

Kinsta was the first managed WordPress host to utilize Google Cloud Platform exclusively, and our team knows it better than anyone else in the industry! Our entire infrastructure is built and optimized around it, including features that others don’t include, such as its premium tier network. Not to mention we roll out new data center locations as soon as they are available. We currently offer 37 different locations.

We do support different than anyone else. We don’t hire level 1 or level 2 support reps. Our team is comprised of only the best Linux engineers and WordPress developers. You get to chat with the same team members that support our Fortune 500 companies! This means fewer frustrations, less bouncing around, and ensures you get your problems resolved fast. We are available 24/7.

Are Any Countries Blocked on Google Cloud Platform?

Google does block access to some of its business services in certain countries or regions, such as Cuba, Crimea, Iran, North Korea, Sudan, and Syria. This is due to legal restrictions that are imposed. More details and an updated list can be found here: U.S. Department of the Treasury. If you are traveling in one of these countries and are needing to update your site or access MyKinsta, you can use a VPN such as ExpressVPN or NordVPN.

What about China? Your sites should be accessible within China. In fact, we have many many clients currently targeting China just fine. However, we also can’t guarantee accessibility as we have zero control over what the Chinese government may choose to block. Navi from Google Support has also stated:

Google Cloud Platform does not have a restriction on the traffic coming from China. If you are hosting a website on GCP, traffic coming from the China users will not be blocked.

That being said, Google does not have any control over the GFW blocking methods.

You can test your website to see if it’s accessible behind the Great Firewall of China.

What is Kinsta’s Cloudflare Integration?

All sites on Kinsta are protected by our free Cloudflare integration. Cloudflare is a leading provider of web security and performance services. With our Cloudflare integration, sites hosted on Kinsta are protected by an intelligent firewall that also includes free DDoS protection. Click to learn more about Kinsta’s Cloudflare integration.
