Best Webflow Frameworks: Client-First, Lumos and More in 2025

When you start a new Webflow project, the structure matters just as much as the design. A good framework saves time, keeps your build consistent, and makes handoff easier for teams or clients. In 2025, Webflow developers are spoiled with some amazing frameworks.
Let’s break down the best Webflow frameworks you should know this year, Client-First, Lumos, and more.

Why Use a Webflow Framework?

If you’ve ever opened someone else’s Webflow project and felt lost, you already know the answer. Frameworks:

• Consistency means your future self (and teammates) will thank you
• Make projects scalable
• Speed up development
• Improve collaboration across teams
• Reduce confusion for clients after handoff

Now, let's explore each framework and what makes them valuable.

1. Client-First by Finsweet

Client-First is the gold standard for Webflow frameworks. Developed by Finsweet, it’s widely adopted by freelancers, agencies, and in-house teams.

Pros

• Clear class naming system that anyone can understand
• Easy for clients to edit after handoff
• Tons of documentation and community support
• Regular updates that match Webflow’s new features

Cons

• Can feel heavy with more nesting
• Slight learning curve for beginners

Best for: Agencies, freelancers, and anyone who works on projects that require clean, scalable builds.

2. Lumos Framework

Lumos is the new kid on the block, but it’s quickly gaining popularity. It focuses on speed, performance, and minimalism, perfect for developers who want to build lean websites without clutter.

Pros

• Lightweight classes for faster performance
• Component-based system that makes reuse easy
• Modern approach designed with 2025 Webflow features in mind

Cons

• Slightly more difficult to learn at first

3. Founder-First (by HeyAyu)

Founder-First is a newer framework designed with simplicity and scalability in mind. It takes inspiration from existing frameworks but focuses on clarity and usability above all.

Pros

• Uses less nesting for cleaner builds
• Component-style structure makes it easy for clients to make changes
• Very open and flexible, adapts to different project types
• Beginner-friendly while still powerful for advanced use

Cons

• Newer framework, so community support is still growing
• Not as many ready-made resources as larger frameworks

Best for: Developers and teams who want a balance of structure and freedom without over-complication.

Which Webflow Framework Should You Choose?

Here’s the simple way to decide:

• Choose Client-First if you want the safest, most supported option.
• Choose Lumos if you prefer lightweight, component-based builds and don’t mind a learning curve.
• Choose Founder-First if you want a framework that’s simple, open, and easy to adopt while still scalable.

At the end of the day, the “best” framework is the one that helps you build efficiently while keeping your projects scalable and easy to maintain.

Final Thoughts

Frameworks are not about limiting your creativity, they’re about making sure your creativity is supported by structure. In 2025, Webflow has matured into a platform where using a framework isn’t just nice-to-have, it’s essential for professional work.

Whether you stick with Client-First, experiment with Lumos, adopt Founder-First, or mix in other systems, the goal is the same: build websites that are fast, scalable, and easy for both developers and clients to love.

Frequently Asked Questions

1. What is a Webflow framework?

A Webflow framework is a system of class naming, structure, and guidelines that makes building websites faster, more organized, and scalable. It’s like a blueprint that keeps your project consistent and easy to manage.

2. Is Client-First still the best Webflow framework in 2025?

Client-First is still one of the most widely used frameworks because of its documentation and community support. However, newer frameworks like Lumos and Founder-First are offering fresh approaches that focus on flexibility, less nesting, and easier adoption.

3. Which Webflow framework is best for beginners?

Founder-First is very beginner-friendly because it uses less nesting and has a simple, component-style approach. Client-First is also a good option for beginners who want a large support community.

4. Why should I use a Webflow framework instead of building from scratch?

Using a framework saves time, keeps your classes consistent, reduces confusion during handoff, and makes scaling easier. Without a framework, projects often become messy and harder to maintain.

5. Can I switch frameworks after starting a project?

It’s possible, but not recommended. Switching frameworks mid-project often requires reworking class structures, which can take a lot of time. It’s better to choose your framework at the start of a project.

6. What makes Founder-First different from other frameworks?

Founder-First is designed to be simple and open. It uses less nesting than Client-First and is easier to learn than Lumos, making it a balance between structure and flexibility.

7. Are Webflow frameworks free to use?

Yes, most frameworks like Client-First, Lumos, and Founder-First are free. Some UI kit–based frameworks, like SystemFlow or Relume Library, may offer premium components, but the frameworks themselves are usually free to adopt.
