Firebase vs WordPress: Why We Stopped Building on WordPress

WordPress powers 40% of the web. We used to build on it too. Then we switched to Firebase and Google Cloud for client projects. Here is an honest look at why, and when WordPress still makes sense.

This is not a hit piece on WordPress. WordPress is a remarkable piece of software that democratised web publishing and gave millions of people a voice online. It earned its dominance. But dominance does not mean it is the right choice for every project, and after years of building WordPress sites for small businesses, we moved away from it for most of the work we do.

Here is why, with the trade-offs stated honestly.

Security: the plugin problem

WordPress itself is reasonably secure. The core team takes security seriously and patches vulnerabilities quickly. The problem is everything that gets bolted on top of it.

A typical small business WordPress site has somewhere between 15 and 30 plugins installed. A contact form plugin. An SEO plugin. A caching plugin. A security plugin (the irony of needing a security plugin to secure your platform is not lost on us). A backup plugin. A slider. A page builder. Maybe WooCommerce. Each one of these plugins is a separate piece of software, written by a separate developer or team, with its own update cycle and its own potential vulnerabilities.

When a vulnerability is found in a popular plugin, automated bots start scanning every WordPress site on the internet within hours. If your site has the vulnerable plugin and has not been updated, it gets compromised. This is not theoretical. We have cleaned up hacked WordPress sites for clients. It is messy, time-consuming, and sometimes results in permanent damage to search rankings.

Firebase Hosting serves static files from Google's global CDN. There is no server-side code running. No database to inject SQL into. No admin login page for bots to brute-force. No plugins to exploit. The attack surface is, for practical purposes, zero.

Performance: CDN by default

When someone visits a WordPress site, the server receives the request, runs PHP code, queries a MySQL database, assembles the HTML, and sends it back. Even with caching, that process adds latency. The server is doing work for every visit.

Firebase Hosting serves pre-built files from the nearest Google Cloud edge node. There is no server-side processing. The files already exist. Google just hands them over. The result is page loads that are typically under one second, often under 500 milliseconds.

For a small business website, the difference is real. Google uses page speed as a ranking factor. Visitors bounce from slow sites. Every second of load time costs you conversions. A WordPress site on cheap shared hosting might load in three to five seconds. The same content on Firebase loads in under a second.

This is the same infrastructure that serves YouTube, Gmail, and Google Search. It is not going to struggle with your five-page brochure site.

Cost: free is hard to beat

Firebase Hosting has a free tier that covers most small business websites comfortably. You get 10GB of storage and 360MB per day of data transfer. For a typical brochure site, that is more than enough.

Compare that to WordPress hosting:

• Budget shared hosting: £3–£10/month (slow, shared resources, frequent downtime)
• Managed WordPress hosting: £15–£30/month (better, but still running WordPress)
• Premium managed hosting: £30–£80/month (good performance, but expensive for a small site)

Even at the budget end, that is £36–£120 per year for hosting. With Firebase, it is zero. Over five years, the saving is meaningful for a small business watching every pound.

The StagHill website itself runs on Firebase Hosting. Our cost for hosting this site is nothing. We built PassReady, our driving instructor booking platform, on the same Firebase infrastructure — and even with a full web application running authentication, database operations, and payment processing, the hosting costs are a fraction of what equivalent WordPress hosting would be.

Maintenance: zero vs constant

A WordPress site needs ongoing maintenance to stay secure and functional. WordPress core updates. Plugin updates. Theme updates. PHP version updates. Database optimisation. Backup verification. Security monitoring. Comment spam management.

This is real work. If you do not do it, your site becomes vulnerable. If you pay someone to do it, that is £30–£100 per month on top of your hosting. Over a year, maintenance alone costs more than many businesses paid to build their site in the first place.

A static site on Firebase needs none of this. There is no WordPress to update. No plugins to patch. No database to optimise. No PHP version to manage. Once deployed, it runs. If you want to change something, you edit the files and redeploy. That is the entire maintenance process.

We have client sites on Firebase that we deployed over a year ago. They have required exactly zero maintenance in that time. They are still fast, still secure, still ranking. Try saying that about a WordPress site you have not touched in twelve months.

Scalability: Google Cloud vs shared hosting

Most small business websites do not need to worry about scale. You are not expecting a million visitors a day. But there are moments when it matters — a local news article mentions your business, a social media post goes viral, you run a promotion that drives a spike in traffic.

On shared WordPress hosting, a traffic spike can take your site down. You are sharing server resources with hundreds of other websites. If your site suddenly needs more, there is nothing to give. The server chokes, your site goes offline, and you miss the one moment when people were actually trying to find you.

Firebase Hosting runs on Google's global infrastructure. It scales automatically. A hundred visitors or a hundred thousand — it does not matter. Your site stays up because it is being served from the same network that handles billions of requests per day.

The trade-off: you lose the visual editor

Here is where we need to be honest, because this is the genuine downside.

WordPress has a visual editor. You can log in, click on a page, change some text, hit publish. No developer needed. For businesses that update their website content frequently — daily blog posts, regular product changes, seasonal updates — that self-service capability is valuable.

A Firebase-hosted site does not have that. Changing content means editing code (or HTML files) and redeploying. For a business that updates their site once a month or less, that is fine — you email us the changes and we deploy them. For a business that needs to update content every day, WordPress or a headless CMS might genuinely be the better choice.

We are upfront about this with clients. If frequent self-service content updates are a priority, we will say so and recommend the right tool for the job. We would rather give honest advice than sell someone a solution that does not fit.

When WordPress still wins

WordPress is still the right choice for:

• Content-heavy sites that publish multiple times per week (blogs, news sites, magazines)
• E-commerce where WooCommerce's plugin ecosystem provides genuine value
• Businesses that need non-technical staff to update content daily
• Sites that rely on third-party WordPress integrations that have no alternative

For everything else — brochure sites, landing pages, portfolios, documentation sites, small business websites that change a few times a year — Firebase or similar static hosting is faster, cheaper, more secure, and requires zero ongoing maintenance.
