# http block
map $request_uri $redirect_to {
    default "";
    /blog /library;
    /blog/redis-cache /library/redis-cache;
    /a /b;
    /b /c;
}

# server block
if ($redirect_to) {
    return 301 $redirect_to;
}
location = /old-pricing {
    return 302 /pricing;
}
location ^~ /docs/v1/ {
    rewrite ^/docs/v1/(.*)$ /docs/v2/$1 permanent;
}

/a to /b chains on to /c: point it at /c directly.

301 and 308 are permanent and pass ranking signals to the new URL; 302 and 307 are temporary and keep the old one indexed. An Nginx map is a hash lookup, so thousands of exact redirects cost nothing per request, unlike thousands of location blocks.

Runs in this browser. Nothing you paste is sent to a server.

About this tool

Method, assumptions, practical next steps, and limits.

Redirects after a migration

When URLs change, every indexed page, bookmark and inbound link still points at the old one. A permanent redirect (301 or 308) sends readers to the new page and passes ranking signals to it; Google's redirects documentation recommends server-side permanent redirects for moved content.

Fix chains at the source

If /a redirects to /b and /b to /c, every visit to /a makes two round trips and crawlers may stop following. The generator points out each chain so /a can go straight to /c.

Frequently asked questions

What is the difference between 301 and 308?

Both are permanent. A 308 requires the client to repeat the same method and body, so a POST stays a POST; a 301 lets clients switch to GET. For page moves either works.

How many redirects can Nginx handle?

With a map, tens of thousands of exact redirects cost a hash lookup per request. Thousands of separate location blocks or rewrite rules are slower and harder to maintain.

Is what I paste sent anywhere?

No. The tool runs entirely in your browser with JavaScript. Nothing you type or paste is sent to our server or stored.
