Redirect Supply vs Squarespace URL Mappings: Redirects that outlive your site
Squarespace URL Mappings redirect pages inside your site, written as lines like /old -> /new 301 in a Developer Tools text field. They handle 301s, 302s, and collection variables well, as long as your site stays on Squarespace. Redirect Supply keeps redirects independent of your website, so old URLs, query strings, and even old PDF links keep landing on the right page, wherever your site moves next.

Squarespace URL Mappings or Redirect Supply? The short answer
Use Squarespace URL Mappings for pages that move within a site that's staying on Squarespace.
Use Redirect Supply if you're moving off Squarespace, have more URLs than a text field comfortably holds, or need old campaign links and files to keep working. Redirects stop depending on your site, with a free plan to start.
For leaving Squarespace without losing a single link, that makes it a Redirect Supply job.
FAQs
Questions about Squarespace URL Mappings and Redirect Supply
What are Squarespace URL Mappings?
URL Mappings are Squarespace's redirect tool, found in Developer Tools. Each line sets one redirect, like /old-page -> /new-page 301, with 301 for permanent and 302 for temporary moves, plus a [name] variable for collection items such as blog posts.
How many URL Mappings can I add?
Squarespace limits the URL Mappings field to 400 KB, which is usually around 2,500 lines. Redirect Supply includes unlimited path rules and wildcards on every paid plan.
Why can't I redirect an old PDF or image?
Squarespace URL Mappings can't redirect image or file URLs. When your old domain is connected to Redirect Supply, every path on it can be redirected, including brochures, downloads, and images people linked to years ago.
What happens to my URL Mappings if I move off Squarespace?
URL Mappings only work for pages within your Squarespace site, so they stop applying once the site no longer runs there. Redirect Supply keeps redirects separate from the website, so they carry on through the move. See renaming your website for the full checklist.
Do URL Mappings work with query strings and UTM tags?
Squarespace notes that symbols like ?, &, and # generally interfere with URL Mappings. Redirect Supply keeps query strings by default, so campaign links still report correctly in your analytics.
Can I move my URL Mappings into Redirect Supply?
Yes. Each mapping line already contains the old URL, the new URL, and the redirect type. Put them into a CSV using Redirect Supply's import format, import the file, and update your domain's DNS records when the new site is ready.
