Redirect Mapper - Auto-redirect every 404 to the closest live page

by•
Most redirect tools make you manually map every old URL to a new one — brutal for big migrations. Redirect Mapper does it automatically: it catches each 404 and sends the visitor to the closest live page in real time, using intelligent URL matching. It even self-heals — if a destination later dies, it stops routing there. Plus twice-daily sitemap crawls, analytics on every recovered visit, and manual/wildcard overrides for full control. One script, no dev work, no redirect maps to maintain.

Hey Product Hunt 👋 Having worked on 30+ site migrations, I know how painful redirect maps are. Even when you nail the mapping, rogue 404s always creep up later — and hand-mapping hundreds of old URLs, then monitoring them, is tedious, error-prone, and never really "done." Every one you miss is a visitor who hits a dead end and bounces. So I made it automatic. Redirect Mapper catches every 404 in real time and sends the visitor to the closest matching live page, using intelligent URL matching — no manual redirect maps required (though it can generate a redirect-map document for you if you want one). A few things I'm especially proud of: • Self-healing — if a destination later goes dead, it detects it and stops routing traffic there. I haven't seen other tools do this. • Auto sitemap crawling so the URL index stays fresh as your site changes. • Analytics on every recovered visit — see which broken links cost you traffic and where visitors came from. • Manual & wildcard overrides for when you want precise control. Setup is one script snippet — no dev work free tier to try on a live site. I'd love your feedback, especially from anyone who's survived a painful migration. What would make this a no-brainer for you? 🙏

dropped it on a messy wordpress migration and was honestly shocked it figured out decent matches without any setup on my end. the self-healing bit is the part i did not know i needed until now.

 amazing! thanks for the note :)

How does the intelligent URL matching actually decide what's "closest" when the old and new URL structures are totally different, like a /blog/post-name path needing to land on a /resources/article-name page?

 Hi Kerem, it looks at the keywords found in the URL paths (found in your XML sitemap) and determines the closest matching live page. Eventually, we will add in crawling of other elements (like the H1 tag and Page Title) in order to get a better quality score for the URL matching.
