Why the Rules Are Built in Your Browser
An .htaccess file is one of the few places where a copy and paste mistake takes a whole site offline. That shaped every decision here.
What This Generator Does and Does Not Do
Pick options, read the file, paste it into your web root. The rule generator covers redirects, security headers, access control, compression, caching and the handful of settings that come up on nearly every Apache site. Each block arrives with a comment saying what it does and which module it needs, because a file full of anonymous RewriteCond lines is a problem waiting for the next person who opens it.
No server, so nothing to leak
Every rule is assembled by JavaScript in the page you are reading. Nothing is posted anywhere, there is no account, and no configuration is stored. The .htpasswd hash is computed locally too, which matters: sending a password to a stranger's server to have it hashed is a bad habit, however convenient the site looks. Load the page once and the tool keeps working with the network switched off.
Where the output stops being enough
A generator writes syntax. It cannot know that your host runs PHP-FPM, that a plugin already added a redirect for that path, or that your staging domain sits behind a proxy that strips headers.
Read what the browser actually receives, not what the config says it should send. Those two disagree more often than you would think.
Directives placed in the main server config also beat anything in a per-directory file, and Apache has to check for these files on every request, so a busy site is better off moving the rules into the vhost. The AllowOverride documentation spells out the tradeoff and which directive groups a host can permit.
Apache 2.4, with 2.2 in the comments
Output uses 2.4 syntax. Access control changed between the two versions, and a 2.2 style rule can fail quietly on a 2.4 server, so every access block carries the old form commented underneath. If you inherit a server and cannot tell which version it runs, that comment saves a support ticket.
Who it is for
Developers setting up a new site, agency folks moving a client to a new domain, and anyone who has stared at a redirect loop wondering which of four rules caused it. Rules written here pair well with a check of what the live server returns afterwards. Something wrong or missing? The contact page covers what to send, the privacy policy confirms the no-upload claim above, and the terms of use handle the legal minimum in plain language.
