Filter Forge

Turn a Diablo 4 build guide into in-game loot filter import codes, with adjustable strictness.

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 Filter Forge is a fan-made tool and is not affiliated with or endorsed by Blizzard Entertainment.
