DIY vs. Agency Website Maintenance: An Honest Comparison

Every business reaches the same point sooner or later. The site is slow, or a plugin update has broken the contact form, or the hosting bill has gone up, and someone asks: "Can't we just handle this ourselves?"
Sometimes the answer is yes. This post covers when DIY makes sense, when it doesn't, and how your hosting and platform choices change the answer.
If you're still deciding what to build on, start with our guide on whether your business really needs a CMS. This post picks up once you have a site and need to look after it.
Shared hosting: cheap and simple, until it isn't
Shared hosting puts your site on a server with hundreds of others. For a small brochure site with modest traffic, it's often perfectly fine. The problems tend to appear as you grow:
- Noisy neighbours. You share CPU, memory and disk speed. If another site spikes or gets compromised, yours can slow down through no fault of its own.
- Hidden limits. Hosts cap processes and CPU time, often throttling quietly. A successful email campaign can push you over the limit at the worst moment.
- Limited control. No root access, restricted PHP versions, and little room for performance tools like object caching.
- Shared reputation. A spammy neighbour on your IP can hurt your email deliverability.
- Weaker isolation. Good hosts separate accounts well, but a shared environment still carries more risk than a dedicated one.
- A cliff, not a ramp. Outgrowing shared hosting usually means a full migration.
- The renewal surprise. Low introductory prices often jump, and staging or better backups may cost extra.
Cloud and VPS: Hetzner, DigitalOcean, AWS
A VPS or cloud server gives you dedicated resources, root access, snapshots and the freedom to resize. Hetzner and DigitalOcean offer strong performance for the price. AWS is enormously flexible, but complex, and bills can surprise you if nobody is watching.
Here's the catch that rarely makes it into "just move to a VPS" advice: an unmanaged server is a job, not a product. Someone has to handle:
- Operating system and security patching
- Firewall and SSH hardening
- Backups, and, just as importantly, testing that they restore
- Uptime and performance monitoring
- SSL renewals
- PHP and database updates
- Email configuration
You've swapped "my host limits me" for "I'm now the sysadmin."
The middle ground
Managed WordPress hosts (Kinsta, WP Engine and similar) and control-panel tools such as Cloudways, SpinupWP, RunCloud or Ploi sit in between. They take care of much of the routine server work, and they suit many small businesses. But they don't look after the website itself: plugin updates, broken layouts and security scanning are still yours.
Your CMS decides how much maintenance there is
Wix and Squarespace
Hosting, security and core updates are handled for you. DIY is very realistic, as long as you're happy with the platform's limits.
Shopify
The platform is looked after, but your theme, apps and integrations still need attention. And because it's a shop, downtime costs sales directly.
WordPress
The most flexible option, and the one with the most moving parts. Core, theme and plugin updates, security scanning and compatibility checks are ongoing, and the plugin ecosystem is where most problems start.
Craft CMS and Drupal
Powerful and tightly controlled, but they need developer-level care for updates and upgrades. Rarely DIY territory.
DIY is a realistic option if:
- Your site is a simple brochure site that rarely changes
- It's built on Wix or Squarespace, where the platform handles hosting, security and core updates
- Someone in-house is technically confident and has time to spare
- A few hours of downtime wouldn't cost you customers or revenue
It's worth getting help if:
- The site is your main source of leads, or you sell through it
- You're running paid campaigns to it, where speed and uptime directly affect ad spend
- It's self-hosted WordPress with lots of plugins, or a Craft or Drupal build
- You handle personal data, payments or compliance requirements
- Nobody on the team is comfortable with servers, updates or backups
If you're still not sure, three questions cut through most of it:
- What does an hour of downtime cost us? If the honest answer is "not much", DIY is far less risky.
- Who would notice if something broke? Not who would fix it, who would notice. Problems that nobody sees are the expensive ones.
- If it broke tonight, who could fix it? If the answer is "I'd have to Google it", that tells you something.
What DIY really costs
Most people compare DIY to an agency by looking at the invoice. That's the wrong comparison.
Your time isn't free. A few hours a month on updates, backups and troubleshooting adds up, and it comes out of time you'd spend running the business.
The expensive problems are the ones nobody was watching for. The expired certificate. The backup that has been failing for three months. The plugin vulnerability that sat unpatched for a fortnight. Maintenance is mostly boring, until the day it becomes the most important thing in the company.
That's the real value of proper maintenance. It isn't the hours of work, it's having someone whose job is to notice things before they become incidents. That might be you, a colleague or an outside partner, but it needs to be somebody's job.
When DIY is the right call
We'd be doing you a disservice if we said everyone needs an agency. If your site is simple, your traffic is modest and you have the time and inclination, doing it yourself on good managed hosting is a perfectly reasonable choice. Set a monthly reminder, keep backups off-site, and test a restore at least once.
If the site brings in leads or revenue, the maths usually tips the other way. Prevention costs a small, predictable amount of time or money each month. Recovery costs whatever the outage happens to cost.
