DOMsters by Maillo
Turn any website into a turn-based creature RPG. Every page hides a creature born from its own DOM.
Extension Metadata
About this extension
DOMsters turns the web you already browse into a creature-collecting RPG.
Open any page, hit Scan, and the extension reads the structure of that page — how
many elements, links, forms and layers deep it goes — to generate the creature
that lives there. The species comes from the domain and its real DOM, so a news
site never gives you the same monster as a shop or a forum: each page has ITS
creature, and it stays that creature.
Then you fight it. Turn-based combat with type advantages, 200+ perks, status
effects (poison, burn, freeze, paralysis) and ATB bars that fill with your
creature's speed. Win and you can capture it, level it, evolve it, fuse it with
another, or take it into the arenas against animated bosses.
WHAT'S IN IT
• Deterministic creature generation from the real DOM of the page you're on
• Turn-based combat: type chart, STAB, criticals driven by a LUCK stat, 200+ perks
• 10 page types (social, news, video, shop, blog, forum, docs, gaming, hacker, misc)
• Rarities and variants — Prisma (1%) and Glitch (0.1%)
• Arenas with bosses, fusion lab, evolutions, prestige, daily missions and PvP
• Pixel-art sprites, chiptune sound, and an overlay that stays out of your way
• Cloud save: your collection follows your account, not your machine
• English and Spanish
PRIVACY, PLAINLY
Only the DOMAIN of the page you scan is sent (from opera.com/gx only opera.com
travels), plus a handful of numeric DOM metrics. Never the path, the parameters,
the page content, or anything you type. The extension does not request access to
your history or your tabs. No third-party trackers, no ads, no data selling. The
code ships unobfuscated — check it in your network tab.

BETA
This is a public beta. Expect rough edges, and tell me about them. Progress could
be reset during the beta; you'd be warned first.
