Platform Overviews
Replit AI
Replit is a browser-based collaborative IDE and cloud hosting platform that has added AI coding features (Replit AI, previously Ghostwriter) to help developers build and deploy applications entirely in the browser — from writing code to running servers to deploying production apps without any local setup. It's particularly popular in education, competitive programming, and with developers who need a zero-setup environment for prototyping or collaboration. Replit can deploy web servers, databases, and static sites from the same workspace. Apps deployed on Replit are served from *.repl.co or *.replit.app domains with Replit-specific server headers, and the Replit runtime injects platform-specific variables into the environment. Replit's free tier is generous, with Core plans at $20/month for more compute and storage.
Webflow
Webflow is the most powerful no-code website builder available, offering pixel-perfect visual design control with a built-in CMS, e-commerce, and advanced animation capabilities. Unlike most builders, Webflow gives designers and developers full CSS control through a visual interface — making it popular with agencies, freelancers, and in-house design teams who need professional results without a frontend developer. Every Webflow page is uniquely identifiable through injected data-wf-page and data-wf-site attributes on the HTML element, proprietary CSS classes (w-nav, w-layout-grid, w-dyn-item), and assets served from uploads-ssl.webflow.com and assets.website-files.com CDNs. The Webflow JS runtime (webflow.js) is loaded on every published site, and Webflow-hosted sites return server: Webflow in their HTTP headers. Site plans start at $14/month, with workspace plans for agencies from $19/month.
Key Differences

- Our detection engine identifies Replit AI using 7 fingerprint patterns and Webflow using 13 patterns — more signals generally means more reliable detection.
- Replit AI serves assets from
/repl\.co/iwhile Webflow uses/assets\.website-files\.com/i— making CDN domain analysis one of the most reliable ways to distinguish them.
