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? 🙏
