Nginx / .htaccess Rule Simulator

Run supported redirect and rewrite rules against test paths in an isolated server.

Rewrite and redirect directives only. Includes, file access, proxying and executable directives are rejected.

Up to ten paths beginning with /, one per line.

One server job runs at a time. Private reports last up to 24 hours; the shared history retains at most 500 finished jobs. Download evidence you need to keep. Jobs have a three-minute execution budget; limits may stop a complex page earlier.

Verify a domain for origin checks, browser actions or webhook delivery

Publish the unique value in a DNS TXT record or a small file on your HTTPS website. Verification lasts 24 hours in this browser session.

What you can investigate

Run supported redirect and rewrite rules against test paths in an isolated server. Review the affected endpoint or page, the measurement time and the suggested next action before changing your site.

Scope and privacy

Inputs and results are encrypted in our database and tied to this browser’s private ownership cookie. Only public destinations are allowed. Reports last up to 24 hours within the shared 500-report history; private recovery backups have a separate lifetime.

Paste supported rewrite directives, not a whole virtual host. The isolated server has only a synthetic index and target.txt file. Actual production modules, filesystem contents and application routes can change the result.
