Filter Forge

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
• Nothing is sent to any server we run — it reads the page you're already on, in your own browser
• Never asks for anything beyond the build page you open it on
