D2ArmorPicker searches armor in your account. D2 Armor Lab plans rolls to farm without a login. Use the first when the armor is in your vault and the second when you are still looking for it.
Plan armor without signing inThe tools start with different information. D2 Armor Lab uses target stats. D2ArmorPicker uses owned inventory.
| Decision | D2 Armor Lab | D2ArmorPicker |
|---|---|---|
| Primary job | Tell you what archetypes and rolls to farm | Find builds from armor already owned |
| Bungie login | Not required | Required for inventory access |
| Vault data | Does not read it | Uses it to test real combinations |
| Armor 3.0 planning | 12 archetypes, tertiaries, mods, and tuning | Best used after matching pieces are acquired |
| Best moment to use | Before and during the farm | When assembling a real loadout |
Use D2 Armor Lab when your question is "What do I need?" Enter six target stats and any subclass fragment changes. The calculator recommends five archetype and tertiary profiles for that distribution. It does not assume those pieces are already in your account.
It can also plan target rolls while an inventory service is unavailable. The target setup link keeps the six targets, fragment changes, and minor-mod count in the URL.
Use D2ArmorPicker when your question is "What can I equip right now?" Inventory access lets it compare real rolls across characters and the vault. A theoretical planner cannot see your Exotic, armor sets, or slot inventory.
One practical workflow is to plan here, farm the recommended profiles, then check the new pieces in an inventory optimizer.
Any tool that reads private Destiny inventory needs Bungie authorization. Before authorizing a third-party tool, confirm that the browser is on Bungie's real sign-in domain, read the requested permissions, and never type platform credentials into a form hosted by the third-party site itself. Revoke access from your Bungie account if you no longer use a service.
D2 Armor Lab has no account button, OAuth flow, API token, or server-side saved build. It cannot inspect your inventory.
Use a theoretical armor stat calculator when you need to know which archetypes and tertiary rolls to farm. D2 Armor Lab handles that step without account authorization.
No. It has no Bungie sign-in and no access to characters, inventory, or account data. It produces a theoretical farming plan from values you enter.
Yes. Plan the profiles here, collect matching pieces, then use D2ArmorPicker or DIM to assemble a loadout from the armor you own.
A no-login calculator can still plan future rolls because it does not depend on Bungie account authorization. It cannot inspect owned pieces, so inventory optimization must wait until the authorized service is available again.
