Webflow Reverse Proxy Overview: What It Is, Why It Matters, and When to Use It

This is Article 1 in my Reverse Proxy Series.

Reverse proxies are the gateway drug to Webflow Enterprise. Almost every enterprise project I’ve been involved in has implemented it in some form.

They’re the Swiss Army knife that lets you rethink the process for massive projects and build the kind of enterprise setups that get you the good contracts.

This series of guides/articles/words should cover everything you need to know, from a basic “hello world” reverse proxy to a tested client-ready repo.

First. I want to translate “Webflow Enterprise” into my own words. From my experience, Webflow Enterprise simply means:

“High risk, high reward, high complexity Webflow projects. Bypassing the limits of Webflow and pushing the boundaries in terms of size and complexity for brands with sophisticated online marketing.”

Reverse proxies are one of many tools that help you manage that complexity.

Companies that are serious about their online marketing will have many web initiatives in different places.

Marketing is about experimentation. Teams are constantly testing new ideas and trying things. It’s unlikely that a company will have everything on one platform. 

In reality, they’ll have a main marketing site somewhere easy to edit (Webflow in our case), a blog / thought leadership in a CMS that’s relatively easy to edit, most likely Wordpress, a selection of short term marketing campaigns across the web, their main web app and maybe a help center. 

Putting each of these on their own subdomain doesn’t cut it. That’s split SEO authority and a confusing user experience. These companies need everything on their main domain

The only way we can get all these initiatives into the main domain is with a reverse proxy.

What Is a Reverse Proxy?

A reverse proxy is a router for your domain

When someone visits your site, instead of going directly to Webflow, they hit your reverse proxy first. This little piece of JavaScript looks at what they're asking for and decides where to get it:

• domain.com → Fetch from Webflow (main.domain.com)
• domain.com/blog → Fetch from WordPress (blog.domain.com)
• domain.com/app → Fetch from Vercel (app.domain.com)
• domain.com/help → Fetch from Zendesk (help.domain.com)

The visitor never knows. Google never knows. It all looks like one cohesive website.

Without reverse proxy:
User → domain.com → Webflow

With reverse proxy:
User → domain.com → Your reverse proxy 
                                        ↓
                            /blog? → WordPress
                            /app? → Vercel  
                            /help? → Different Webflow project
                            Everything else? → Main Webflow project

‍

Your reverse proxy fetches the content from the right place and serves it back. One domain. Multiple sources.

Why This Matters 

1. Enterprise Deals

Big companies don't do subdomains for their main properties. They just don't.

When Coca-Cola wants coca-cola.com/sustainability, they don't want to hear about sustainability.coca-cola.com

They also don’t want you goofing around on their main site, risking catastrophe. 

2. Migrate in small(er) chunks

Client has a 5-year-old WordPress site and 1,200 blog articles?

Instead of the all-or-nothing Webflow migration that'll take 6 months and be 400% over budget, you can:

1. Move the homepage and key landing pages to Webflow
2. Leave the blog on WordPress (for now)
3. Gradually migrate pages as budget allows

This is how you turn a $200k slog into five $50k projects (because you’re guaranteeing a level of safety).

3. Improve SEO (in niche cases)

With a reverse proxy, you can inject whatever you want into the HTML before it reaches the browser (or crawler). You can make an API call to an external data source, add the result to the HTML, and deliver it to crawlers, meaning it gets indexed by Google. 

4. Bandwidth Becomes Cloudflare's Problem

Every request through your reverse proxy gets cached at Cloudflare's edge. Meaning your client's Webflow bandwidth barely moves. Not to mention, page load speeds improve too because they're delivered from the nearest edge location.

The Pros and Cons

Pros ✅

• Unlimited Webflow projects on one domain
• Mix any platforms (Webflow + WordPress + React + whatever)
• Modify HTML before serving (fix SEO, add scripts, inject data)
• Better performance through edge caching

Cons ❌

• Another moving part (one more thing that could break)
• Learning curve (it's not hard, but it's new)
• Cloudflare costs (~$5/month for most sites, but still)

The Alternatives (And Why They're Usually Worse)

Option 1: Subdomain Everything

• blog.domain.com, app.domain.com, etc.
• Pros: Dead simple
• Cons: Looks unprofessional, SEO implications, clients hate it

Option 2: Manual HTML Export

• Export from Webflow, host elsewhere
• Pros: Total control
• Cons: Loses CMS and Editor; nightmare process for changes; why even use Webflow?

Option 3: Just Say No to Complex Projects

• Stick to simple Webflow sites
• Pros: Easy life, referral bonuses
• Cons: Miss out on enterprise clients and interesting challenges

Option 4: Custom Build Everything

• Abandon Webflow, go full custom
• Pros: Ultimate flexibility
• Cons: 10x the time, 10x the cost, client loses visual editing, marketing teams will slash your tyres.

Who Needs This?

You NEED a reverse proxy if:

• You're working with enterprise clients who have complex requirements
• You need multiple Webflow projects on one domain
• You're doing a phased migration from another platform
• You need serious SEO modifications beyond Webflow's capabilities
• You're building hybrid experiences (marketing site + web app)

You DON'T need a reverse proxy if:

• You're building simple marketing sites
• The client is fine with subdomains
• It's a small business that just needs a web presence
• Your client has only ever had one website.

"What's the Skill Level Required?"

You need to be comfortable with:

• Basic JavaScript (if/else statements, fetch requests, async/await)
• Copy-pasting code and changing values
• Following documentation
• Moving slowly and testing aggressively.

You DON'T need to:

• Be a backend developer
• Understand servers deeply
• Know DevOps
• Have a computer science degree

‍

The Path Forward

As Webflow pushes further into enterprise, as companies demand more sophisticated setups, and as the lines blur between marketing sites and web apps, this skill will serve you well.

In the following article, we'll build your first reverse proxy. It'll take 30 minutes, and by the end, you'll have multiple Webflow projects running on one domain.

P.S. it will suck and not be client-ready, but you’ll learn the foundations.

After that, we'll progressively build on it. Catching edge cases, HTML manipulation, managing SEO, and creating GitHub workflows.

But first, take a breath.

This isn't as hard as it seems.

You can handle a bit of JavaScript running in the cloud.
