Arrow to the Build vs Voidforge

Arrow to the Build is a free, offline-first Windows app for tracking Elder Scrolls Online characters and turning builds into progression plans. Its tracker covers character identity, attributes, skills, equipment, Champion Points, skill bars, rotations, companion setups, and build progress. The editor supports guided builds, forks of bundled builds, community JSON imports, and manual editing, with autosave, undo and redo, validation, and revision review. Champion Point routes account for connectors and prerequisites, and include an offline constellation map. An optional bundled ESO addon writes character snapshots through ESO SavedVariables to a local file; the app can also be used manually without it. Character data, settings, snapshots, overrides, and progress are stored in a local SQLite database in the Windows app-data folder, without an ATTB account or cloud database. Builds and themes use portable JSON formats. The app includes 20 themes and an editor with simple 28-color and advanced 57-token modes, plus seven bundled class builds. The maker describes the project as unofficial and unaffiliated with ZeniMax Media, Bethesda Softworks, or The Elder Scrolls Online.

Voidforge is a free web-based Warframe build planner and theorycrafting toolkit. It calculates stats in real time and provides damage simulations with faction-specific time-to-kill estimates. Builders cover weapons, Warframes, companions, Archwing, Necramechs, Railjack, and modular weapons. The Weapon Builder handles mods, arcanes, rivens, and Incarnons, then reports burst and sustained DPS, status breakdowns, and elemental combinations. Its Damage Simulator includes Viral and Corrosive effects, damage over time, and armor reduction. A Codex lists mods, arcanes, Archon Shards, weapons, and Warframes with effects and data coverage. Users can save builds locally or to an account, import or export loadouts, publish builds, browse and upvote community loadouts, and share profiles. There is no paywall or premium tier; donations are optional. The project is MIT-licensed open source, but its repository is not intended for self-hosting.
