How can I reverse engineer someone else's work in Webflow?

TL;DR
  • Use browser DevTools to inspect the site’s HTML structure, CSS classes, and layout patterns.
  • Analyze styles, fonts, and media queries via the Styles and Computed panels.
  • Investigate interactions using data attributes, animations, and behavior during scroll or hover.
  • Review published scripts, assets, and Webflow-generated code for further insight.
  • Utilize third-party tools like Wappalyzer or Udesly to streamline class and tech analysis.
  • Rebuild the project manually in Webflow, replicating structure and interactions based on findings.

To reverse engineer someone else's work in Webflow, you need to analyze the live website structure, styles, interactions, and assets using browser tools and online inspection utilities.

1. Inspect the Webflow-Powered Site

  • Right-click and choose "Inspect" or press Cmd+Option+I (Mac) / Ctrl+Shift+I (Windows) to open DevTools.
  • Look at the HTML structure, CSS class names, and layout. Webflow uses class-based styling, so you'll often see structured class names like section, container, or custom BEM-like patterns.
  • Note recurring patterns, component nesting, and how elements are grouped to understand layout logic.

2. Explore the Styles and Fonts

  • In DevTools, click on an element and check the Styles panel to view CSS properties, Webflow-specific styles, and breakpoint adjustments.
  • Go to the Computed tab to see the effective styles after inheritance and overrides.
  • Check which Google Fonts or custom fonts are loaded by looking under the Network > Fonts tab or the site’s <link> tags.

3. Analyze Interactions and Animations

  • Webflow interactions typically translate to CSS transitions, transform, or JavaScript-based animations.
  • Check for data-w-id attributes, which are specific to Webflow’s IX2 (Interactions 2.0) engine.
  • Use DevTools’ Performance and Elements tabs to monitor how animations respond during scroll or hover.

4. Review the Published Scripts and Assets

  • Open the Sources tab in DevTools to browse the public JS files, images, and custom embeds.
  • If the site uses Webflow-hosted assets, the URLs will contain cdn-cgi or uploads-ssl.webflow.com domains.
  • Check the site footer—Webflow may generate its own scripts (e.g., webflow.js) which also gives hints about how interactions are handled.

5. Use Third-Party Tools to Support Analysis

  • Wappalyzer or BuiltWith can confirm the site is built with Webflow and identify any 3rd-party tools used.
  • Use Udesly’s Webflow Class Inspector (Chrome extension) to list all classes used on the page in a more readable format.
  • Tools like Webflow Reverse Utility (unofficial) may extract a basic class hierarchy if publicly available.

6. Rebuild in Your Own Project

  • Open your Webflow project and manually recreate the layout and classes based on your findings.
  • Apply similar structure, spacing, and interactions using Webflow’s visual tools.
  • Avoid copying assets, code, or content without permission—use the reverse engineering only for learning or inspiration.

Summary

To reverse engineer a Webflow site, inspect the HTML, CSS, and interactions using browser DevTools and third-party extensions. Study layout structures, class naming, and animations to understand the build, then recreate it in your own Webflow project layer by layer while respecting copyright and licensing.
