Site Slayer: The Add-On That Tears Apart the Page You're On
No URL pasting, no separate game site: Site Slayer is a browser add-on that turns the tab you are already looking at into the level — then gives you ships, power-ups and achievements to break it with.
What Site Slayer is
Every game in this genre has the same awkward middle step: you leave the offending website, go to a game site, and paste the URL in. Site Slayer skips all of it. It is a browser add-on — listed on the Firefox and Edge add-on stores — that arms itself on the page you are currently viewing. One click, and the page you were reading is now a playground: pick one of several destruction modes, choose a ship, and start taking the layout apart where it stands.
If Page Rage's extension is a fast route from annoyance to demolition, Site Slayer is instant teleportation: there is no destination, because the destruction happens in place. That directness, plus the deepest set of "game-like" systems in the genre — modes, a fleet of ships, power-ups, leaderboards and an achievement list north of fifty items — makes it the pick for players who want purpose with their catharsis.
Install and play
- Open your browser's official add-on store (Firefox Add-ons or Microsoft Edge Add-ons) and search for Site Slayer.
- Install it like any extension — no account, no payment.
- Browse to any website you've had enough of, and activate Site Slayer from your toolbar.
- Pick a destruction mode and a ship, then go to work on the page in front of you.
As always in this genre: you are working on the browser's copy of the page. The real site is untouched, and nothing leaves your machine.
What's inside (why it's more "game" than "toy")
- Multiple destruction modes. Different flavors of demolition for different moods — from precise, surgical teardown to full-area chaos. Switching modes is the quickest way to make a familiar page feel new again.
- A fleet of ships. Rather than one fixed character, Site Slayer gives you a roster of ships, which changes how you approach each page and adds a light progression hook.
- Power-ups. Drops and boosts that spike your destruction power mid-run — the arcade sugar the genre runs on.
- Achievements and leaderboards. Dozens of achievements to chase and public boards to compare against, which is what turns a five-minute novelty into a daily habit.
- Comfort features. Touch controls for tablet play and key rebinding for the picky — small things that show this one was built to be lived in, not just played once.
How it fits with the other two big names
The genre's big three each optimize for something different:
- Destroy Any Website — the original viral hit: arcade arsenal, destruction meter, online multiplayer rooms. Most spectacle.
- Page Rage — jetpack physics sandbox with a browser extension and built-in pages. Smoothest feel.
- Site Slayer — add-on that works on the page you're on, with modes, ships and achievements. Most game structure.
There is no wrong order to try them in, but if you find yourself wanting a reason to come back tomorrow — a board to climb, achievements to tick off — Site Slayer is the one that provides one.

Three habits for a cleaner rampage
- Match mode to page. A dense, text-heavy article rewards a precise mode; a media-heavy homepage is where the loud modes earn their keep.
- Ships are playstyles, not skins. Try two or three before deciding you've seen what the game can do — the fleet exists to be experimented with.
- Use a page you don't need open. It's a copy, so nothing you break is real — but you'll still want a working tab to come back to.
