Filter Forge door WreckWare

Filter Forge turns a Diablo 4 build guide into a ready-to-import loot filter code — no manual rule-building.

Open a build on Maxroll, Mobalytics, D4Builds, or InfinityBuilds. Click the Filter Forge button and it reads
the build's gear, generates one filter per gear set, and gives you a code to paste straight into the game
(Character menu → Loot Filter → New Filter → Import).

WHAT IT DOES
• Reads the build you're already viewing — no separate lookup or manual entry
• Three strictness levels: Leveling, Strict, and Uber Strict
• A Greater Affix slider, tempering affixes, and editable hide rules
• Works with all four major Diablo 4 build sites
• Click "Edit on web" to open the filter in the Filter Forge web editor (filterforge.dev) and adjust it
further: add or remove rules, pick your class and stats, and test a sample drop against your rules
before you import it

WHAT IT DOESN'T DO
• No account, no ads, no analytics, no tracking
• No server of ours — everything happens in your browser
• The only network request it makes on its own is to Maxroll's public API, to read that build's own
data (the same data the Maxroll page you're on already loaded). Nothing else is sent anywhere,
and nothing is sent to us
