Vercel is a cloud platform for building and running fast, modern web experiences. It offers global hosting, serverless functions, edge capabilities, and a smooth developer workflow that fits naturally with today’s frontend-first stacks.
When you combine Webflow with Vercel, you can keep the visual, no-code Webflow editing experience while using Vercel in the background to handle dynamic functionality, connect APIs, and run custom logic securely. Webflow manages your content and design; Vercel powers the “brain” behind forms, calculators, gated content, and more.
For founders and marketers, this means you can keep moving quickly in Webflow without waiting on big engineering projects, while still benefiting from robust, scalable infrastructure and integrations managed by your development or technical partners.
Why integrate Vercel with Webflow
Integrating Vercel with Webflow gives you a clean separation between design and logic. Your site stays easy to update in Webflow, while Vercel’s serverless functions handle tasks like form processing, API calls, and data routing. This reduces technical overhead on your marketing team and keeps your stack flexible.
You can connect your Webflow site to almost any external system through Vercel’s functions. Instead of relying on multiple small integrations, you run your own API layer on Vercel that talks to CRMs, analytics tools, databases, or internal systems, and pass only what you need back to Webflow.
You also gain a more robust, future-proof architecture. As your product and marketing evolve, you can adjust or extend your serverless functions without breaking the Webflow front-end, making it easier to experiment, iterate, and scale without major rebuilds.
How to integrate Vercel with Webflow
Method 1: Use Vercel serverless functions as your API layer
In this approach, Webflow remains your main marketing and content platform, while Vercel provides a lightweight, scalable back-end. Your development team creates serverless functions on Vercel that act as API endpoints. These endpoints can connect to external services such as CRMs, payment providers, email tools, or internal APIs.
From Webflow, you send data to these endpoints using forms, custom attributes, or small snippets of front-end JavaScript added via the Designer or project settings. For example, a lead form in Webflow can post to a Vercel function, which then enriches the data, sends it to your CRM, and triggers a notification. Your visitors see only a smooth on-site experience, while the logic runs securely on Vercel.
This method is ideal if you want to keep Webflow hosting, add custom workflows or integrations that do not exist as native apps, and avoid running your own full server. Vercel’s serverless infrastructure scales automatically with traffic, so you do not need to think about provisioning or managing servers.
Method 2: Use Webflow for marketing and Vercel for your app or dashboard
Another common pattern is to keep marketing and content in Webflow, and host your product, dashboard, or internal tools on Vercel. Your main site stays on Webflow, while a subdomain such as app.yourdomain.com or dashboard.yourdomain.com points to a Vercel-hosted application.
This allows your marketing team to keep full control of landing pages, blog content, and campaigns in Webflow, while your engineering team builds a custom application on Vercel with deeper integrations, authentication, and complex workflows. You can still connect both layers via shared APIs and design systems, so the user journey feels like one unified product.
What you can do with Webflow + Vercel
You can turn simple Webflow forms into powerful workflows by routing submissions through Vercel serverless functions. For example, a “Request demo” form can enrich leads, apply routing rules, and send data to multiple tools (CRM, email, internal notifications) before returning a confirmation or redirect in Webflow.
You can build light calculators, quizzes, or gated resources that rely on back-end logic. Webflow handles the interface and content, while Vercel functions process inputs, talk to external APIs, and return results dynamically, without exposing your logic or keys in the browser.
You can also connect Webflow to internal systems or custom databases that do not have off-the-shelf integrations. Vercel acts as a secure middle layer, translating Webflow requests into the format your internal tools need, so marketing and product pages can display up-to-date information without direct access to sensitive infrastructure.
Best practices
- Clearly define what lives where
Decide which responsibilities belong to Webflow (content, layouts, static pages) and which belong to Vercel (API calls, data processing, secure logic). A simple diagram shared between teams avoids confusion later.
- Treat Vercel functions as your integration hub
Centralise external API calls and integrations in Vercel rather than scattering them across different widgets and scripts. This makes it easier to manage credentials, logging, and error handling, and keeps your Webflow front-end clean.
- Test workflows thoroughly before going live
For each integration, test success, failure, and edge cases in a staging environment. Check that forms degrade gracefully, error messages are clear, and performance remains acceptable on both desktop and mobile before pushing changes to production.
