Most “best hosting” articles are written by someone who’s never actually run more than three websites. The advice sounds fine in isolation — “get unlimited websites!”, “look for good uptime!” — until you’re the one actually managing 100+ live sites and discover that “unlimited websites” was never really the constraint. Resource contention was.
We host more than 100 websites, including production sites we actively edit, deploy and monitor daily. This is what we actually use, why it holds up at that scale, and the specific operational problems nobody warns you about until you hit them.
The Real Problem With Hosting 100+ Sites (It’s Not What You Think)
Almost every shared-hosting plan advertises “unlimited websites” as a headline feature. That’s technically true and almost entirely beside the point. A shared hosting account doesn’t give each website its own CPU core or memory pool — it gives your entire account a shared allowance of PHP workers (the processes that actually execute your site’s code) and CPU/entry-process limits. Adding your 50th WordPress site doesn’t cost you anything until real visitors start hitting all 50 at once. That’s when a plan that felt “unlimited” at 10 sites starts throttling requests at 60.
This is the part most comparison articles skip entirely, because most of them are written by someone testing one demo site, not someone actually running a real multi-site operation with real traffic, real cron jobs, real backups running simultaneously across dozens of installs.
Why We Use Hostinger
We run our sites on Hostinger, and the reasons are specific, not generic marketing points:
- Deploying and deleting sites is genuinely fast and clean. Spinning up a new WordPress install, testing something, and tearing it back down doesn’t leave orphaned databases or half-configured subdomains behind the way some panels do. For an operation running dozens of active experiments alongside production sites, that cleanliness matters more than almost any other single feature.
- It works exceptionally well alongside AI coding tools like Claude Code. A meaningful part of managing our sites now happens through SSH and WP-CLI, scripted and automated with AI assistance rather than clicking through a GUI for every single change. Hostinger’s clean SSH access and WP-CLI support make that workflow genuinely smooth — deploying content, running database queries, managing plugins and diagnosing issues can all happen through a terminal session an AI agent can drive directly, which is a meaningfully different (and faster) operating model than a hosting panel built purely around point-and-click.
- Processing speed holds up under real multi-site load. NVMe storage across their plans is a genuine, measurable difference from older SSD-based shared hosting, particularly once you’re running enough sites that disk I/O actually becomes a bottleneck.
The Problem Nobody Warns You About: Monitoring at Scale
Here’s the honest catch, and it’s the one piece of advice most hosting content won’t give you because most of it is written by affiliates who’ve never had to deal with it: as your sites grow real traffic, you have to actively watch what’s actually consuming your CPU and request allowance, and control your bot traffic — because a huge share of “your” server load on a growing site isn’t human visitors at all. It’s scrapers, vulnerability scanners, and AI crawlers hitting your server around the clock.
Two concrete things that make this manageable rather than a constant fire drill:
- Use the resource-usage dashboard, not guesswork. hPanel shows real-time CPU, entry-process and bandwidth usage per site. If a specific site’s CPU limit or entry-process count is regularly hitting 80%+, that’s your actual bottleneck — not “my JavaScript needs optimizing,” which is where most site owners waste their time looking first.
- The “Stop Running Processes” feature is a genuinely useful safety valve, not just a nice-to-have. When a request gets stuck — a runaway plugin, a broken cron job, a script that’s hung — this feature interrupts long-running or stuck processes without touching your files or data. On a single-site setup, a stuck process might just be an annoyance. Across 100+ sites, a stuck process on one install can quietly eat into the shared resource pool every other site depends on, so having a fast, safe way to kill it without SSHing in and hunting for a PID manually is a real operational advantage, not a marketing bullet point.
The WordPress Security Step Almost Nobody Actually Does
If you’re running WordPress across many sites — and most people managing 100+ websites are — the single highest-leverage security move is changing your default URLs and settings, because the overwhelming majority of WordPress attacks are automated bots hitting the same predictable targets on every single WordPress install on the internet:
- Change your login URL away from the default
/wp-adminor/wp-login.php. Automated brute-force bots specifically target these default paths across millions of sites simultaneously. Moving it isn’t “security through obscurity” snobbery — it eliminates the single largest category of automated login attempts before they ever reach your actual authentication layer. - Disable XML-RPC if you don’t specifically need it. It’s a common vector for brute-force and DDoS amplification attacks, and most sites don’t actually use the functionality it enables.
- Change your database table prefix away from the default
wp_. A default prefix makes certain SQL injection attempts marginally easier to automate at scale; changing it is a small, one-time step during setup. - Rate-limit and monitor login attempts rather than relying on WordPress’s default (essentially nonexistent) protection.
None of these are individually dramatic. Together, across 100+ installs, they’re the difference between spending your week managing sites versus spending it cleaning up compromised ones.
How Hostinger Actually Compares
| Provider | Multi-site model | Starting price | Best for |
|---|---|---|---|
| Hostinger | Unlimited websites on Business/Cloud tiers; dedicated-resource VPS for real scale | ~$3.99/mo shared, ~$7.99/mo cloud | Best balance of price, speed and terminal/AI-driven workflow |
| Cloudways | Unlimited apps per server (billed per server, not per site) | ~$11/mo (DigitalOcean-based) | Teams wanting managed cloud infrastructure without server admin |
| SiteGround GrowBig | Unlimited websites, one shared resource pool | $29.99/mo at renewal (promo pricing much lower) | Users who want SiteGround’s specific caching stack and don’t mind renewal pricing jumps |
The honest read: Cloudways gives you more granular cloud-provider choice, and SiteGround has real caching strengths — but neither is meaningfully cheaper once you account for real renewal pricing, and neither is built around the terminal-first, AI-assisted workflow that’s become the actual bottleneck-remover for managing dozens of sites efficiently.
The Bottom Line
If you’re managing a handful of sites, almost any reputable host works fine and this whole conversation is academic. Past 20-30 active sites, the questions that actually matter change completely: how do you monitor resource consumption before it becomes an outage, how do you kill a stuck process without a support ticket, and how cleanly does your workflow integrate with the AI-assisted tools that are increasingly how multi-site operations actually get managed day to day. That’s the specific set of problems Hostinger has solved well enough for us to run our entire operation on it.
