Last Epoch Planner review
A detailed open-source planner for theorycrafting Last Epoch characters across web and desktop.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Last Epoch Planner is an open-source build-planning tool for Last Epoch players who want to map passive and skill trees, configure equipment, import characters, and examine calculated character statistics and DPS. It is available as a no-install browser version and as offline desktop software for Windows and Linux. The MIT license and single-game focus make it a practical fit for players who prefer an open-source planning workflow centered on Last Epoch rather than a broader multi-game service.
Its main strength is the depth of its build model. The planner supports passive tree planning, skill tree planning for up to five skills, offline character import, and imports from the Last Epoch Tools build planner. Equipment can be configured, crafted, and modified across rare, exalted, unique, legendary, set, and idol items. Character stat calculations, DPS calculations, and build URL import and export round out the workflow, making it suitable for comparing item choices and sharing build configurations. The web, Windows, and Linux versions also give it a useful platform range for desktop-focused players.
The main qualification is calculation coverage. The project states that many stats and modifiers are only partially supported, so results may not always be accurate. That matters most for players who rely on precise affix interactions or treat calculated DPS as definitive. The tool is also narrowly focused on Last Epoch, and skill planning is capped at five skills per build. Choose it if you want an open-source planner with detailed equipment and crafting support, offline character imports, and Last Epoch Tools integration. Players seeking broader game coverage or fully supported stat interactions should consider a different type of planner.
