Why You Should Put a Reverse Proxy in Front of Your Website

If you're running a website, especially one that's growing or getting more traffic, you've probably heard someone mention "you should be using a reverse proxy." And if you nodded along while thinking "sounds important but... do I really need one?", you're not alone. Here's the thing though: you probably do, and it's way simpler than it sounds.

What Is a Reverse Proxy, Anyway?

Let me demystify this. A reverse proxy sits between your users and your actual website server. When someone visits your site, they don't connect directly to your server—they connect to the reverse proxy first. The proxy then fetches the content from your real server and sends it back to the user.

Sounds like an extra step, right? It's actually a genius move. And here's why.

It Shields Your Server From the Worst of the Internet

Your origin server—the actual machine running your site—has a real IP address. If attackers know that IP, they can target it directly. With a reverse proxy in front, your origin server's IP stays hidden. As far as the world is concerned, your reverse proxy is your website.

This matters more than you'd think, especially if you ever get unlucky enough to experience a DDoS attack. Instead of your server getting hammered with malicious traffic, the reverse proxy takes the hit. It can detect and block suspicious traffic before it even reaches your origin server.

It Caches Your Content (Making Everything Faster)

One of the biggest wins with a reverse proxy is caching. When someone requests your homepage, the reverse proxy can store a copy and serve it to the next visitor instantly—without touching your origin server.

This is huge for performance. Images, CSS, JavaScript, HTML—all cached geographically closer to where your users are. Someone visiting from Australia gets your content from an edge server near them instead of waiting for data to travel across the ocean from your server in New York.

Result? Faster load times, less strain on your origin server, happier users.

It Acts as a Security Bouncer

A reverse proxy can inspect incoming traffic and block bad stuff before it reaches your server. We're talking about Web Application Firewall (WAF) features—rules that catch SQL injection attempts, XSS attacks, and other exploits.

Your origin server never even sees the malicious request. The reverse proxy terminates the connection and logs what happened. You get to focus on building your actual site instead of playing whack-a-mole with attackers.

Cloudflare's Free Tier Is Genuinely Good

Here's the beautiful part: you don't need to spend money to get these benefits.

Cloudflare's free plan includes a massive amount of useful stuff:

  • Unmetered DDoS mitigation—Yes, unlimited. Even the free tier protects you from DDoS attacks.
  • Universal SSL certificates—Your site gets HTTPS automatically.
  • Global CDN—Content cached at edge locations worldwide.
  • DNS hosting—Unlimited queries, no throttling.
  • Basic WAF—With managed rulesets to block common attacks.
  • Workers with 100K requests/day—If you want to run edge functions.
  • Page rules (5 of them)—For custom caching behavior.
  • Web analytics—Built-in insights about your traffic.

For most sites, especially if you're just starting out or running a portfolio/blog? The free tier is legitimately all you need. I use Cloudflare for this site personally, and I've never felt the need to upgrade to a paid plan.

The only real limitation is community support instead of dedicated help, but honestly, the Cloudflare docs are pretty solid.

But Cloudflare Isn't Your Only Option

If you want to explore alternatives—or if you're paranoid about putting all your eggs in one basket—there are solid options out there.

Bunny.net has exploded in popularity. It's dirt cheap (especially for bandwidth), crazy fast, and honestly pretty underrated. If you're sensitive to costs, Bunny is worth a look.

Fastly is the choice if you need serious edge compute. It's pricier than Cloudflare, but if you're running complex logic at the edge, it's powerful.

Akamai is enterprise-grade. If you're running a Fortune 500 company, Akamai is the gold standard. For everyone else? Overkill.

Google Cloud CDN and Amazon CloudFront make sense if you're already living in those ecosystems.

Real talk: unless you have a specific reason to switch (you're all-in on AWS, you need Bunny's bandwidth pricing, you need Fastly's compute), Cloudflare is the "no-brainer" choice. It's solid, it's free, and it's gotten better every year.

One More Thing: Multi-CDN as Disaster Backup

Here's something interesting I've noticed: some teams are now running Cloudflare plus a secondary CDN as a backup. Late 2025 and early 2026 saw some pretty significant Cloudflare outages. If you're running something mission-critical and can't afford even a couple hours of downtime, having a second reverse proxy ready to fail over to is smart insurance.

For most of us? Single reverse proxy is fine. But worth knowing if you're building something that needs serious uptime guarantees.

Just Do It

Here's the minimum viable plan:

  1. Sign up for Cloudflare (free account)
  2. Point your domain's nameservers to Cloudflare (takes like 10 minutes)
  3. Enable HTTPS—it's automatic
  4. Enjoy faster load times, DDoS protection, and better security without paying a dime

Seriously, if you're running a website without a reverse proxy, you're leaving performance on the table and making it easier for attackers to find you. The free tier of Cloudflare (or any of the alternatives) solves both problems.

Your users will thank you. Your server will thank you. Your sanity will thank you.
