How it works
If you constantly open staging.example.com links from Slack or email, write one rule that redirects them to example.com. The redirect fires before the page loads, so you never land on the wrong environment again.
Old bookmarks or shared links pointing at deprecated paths can be silently redirected to their current equivalents. One regex covers an entire URL pattern rather than updating every bookmark by hand.
Swap out terminology, fix recurring typos on a vendor portal you cannot edit, or replace a colleague's old username with their new one across every page of your project management tool.
Change where a link points before the user follows it. Useful for redirecting tracking-heavy URLs to clean canonical versions, or for routing internal wiki links to a mirror.
The goal has always been to stay out of the way.

From the maker
Autumn Whisper Glade was built by Sergio Martins to solve a specific, recurring annoyance: too many browser tabs landing on the wrong URL because of stale links, environment mismatches, or third-party pages with text that needed correcting. The first version handled only URL redirects. It was small, fast, and did one thing. That turned out to be enough for a lot of people, and the feedback that came back was almost entirely requests to do more with the same regex engine already under the hood.
Text replacement came in a later release, once it was clear that the same pattern-matching logic could be applied to DOM content after page load. The tricky part was dynamic pages. A lot of modern web apps inject content through JavaScript after the initial HTML is parsed, which means a simple one-time scan misses half the page. Mutation Observers solved that. The extension now watches for DOM changes and applies rules to new nodes as they arrive, which keeps it accurate on React, Vue, and other single-page frameworks without resorting to interval polling that would drain battery and slow tabs.
Frequently asked questions
Add it to Chrome and write your first rule in under two minutes
Add to ChromeNo. Rules are stored in Chrome's own sync storage, which means they travel through Google's standard Chrome sync channel, the same one that syncs your bookmarks and settings. No data goes to any server controlled by this extension. Sergio Martins does not collect or see your rules.
Yes. The extension uses Mutation Observers to watch for DOM changes after the initial page load. When a single-page app or React component injects new content, the extension catches it and applies matching rules to the new nodes. It does not use setInterval polling, so it won't slow down the tab.
It uses JavaScript's built-in RegExp engine, which is the same engine running in Chrome's V8. If you can write it in a JS regex literal, it will work here. Named capture groups, lookaheads, and the standard substitution syntax ($1, $2, etc.) are all supported.
