Publishing a second Webflow project to its staging subdomain (e.g., your-project.webflow.io) does not interfere with your first (live/production) website.
1. Webflow Projects Are Fully Isolated
- Each Webflow project is independent. They have their own design canvas, CMS collections, custom code, and publishing settings.
- Publishing one project (even with the Webflow.io staging URL) has zero impact on another project's domain or live status.
2. Staging URL Use Is Safe
- When you publish to Webflow.io, you’re only deploying to the staging subdomain for that specific project.
- Your first (already live) project uses its own custom domain and staging subdomain, if enabled. These operate in separate environments.
3. Custom Domains Remain Unaffected
- Unless you explicitly assign the same custom domain (e.g., example.com) to both projects, there is no risk of overlap.
- Webflow prevents publishing a custom domain on two different projects at the same time. A domain can belong to only one Webflow project.
Summary
Publishing your second Webflow project only to its staging URL will not interfere with your first project or live website. Projects are isolated, and staging domains are self-contained within each project.
