Skill Tree for Borderlands 4

This unofficial Skill Tree Calculator/Planner for Borderlands 4 lets you explore the Vault Hunters Vex, Rafa, Amon, Harlowe, and C4SH. It displays detailed skill descriptions and stat bonuses, and lets you craft your own builds by selecting passive and action skills, augments, and capstones. You can save and load your favorite builds, share them with the community, highlight skills matching your search terms, and add free text notes. A clean summary view shows allocated points and you can add extra class mod ranks to your build.

This is a fan-made tool with no official affiliation to Gearbox or 2K. Skill data can update remotely at app start when available. Perfect for planning builds when you can't access the game—whether you're in a meeting, at the park, or just relaxing—and designed to be shared with fellow Borderlands players.
