Which to use for what
- Squeezing exact DPS for a serious raid setupBetter pick: OSRS Wiki DPS Calculator
When every fraction of DPS counts, you want the canonical combat math. Wiki DPS Calc uses the wiki's verified formulas and is open-source, so the number you see is the number the whole meta trusts.
- "What do I wear against this boss?" on a tight budgetBetter pick: GearScape
GearScape walks the item space for you and recommends the best setup given your budget and stats. You don't need to know the BiS by heart: give it the NPC and the budget and it returns the gear.
- Comparing two loadouts you already built by handBetter pick: OSRS Wiki DPS Calculator
If you already know which pieces you want to compare, Wiki DPS Calc's precise manual scoring is ideal: load each loadout, tweak prayers, potions and style, and see DPS and time-to-kill side by side.
- Discovering a gear upgrade you hadn't consideredBetter pick: GearScape
Because GearScape searches the whole item space, it often surfaces combos a player wouldn't try by hand. It's the tool for finding the best setup, not just scoring the one you already had in mind.
- Trusting the math on a razor-thin gear decisionBetter pick: OSRS Wiki DPS Calculator
When two options are nearly tied and you need certainty, the open-source nature and provenance from the wiki team make Wiki DPS Calc the authoritative source. Anyone can audit how the number is computed.
Both tools live in the combat-gear category, and both give you DPS, max hit, accuracy and time-to-kill. The real difference isn't whether they calculate, it's who builds the loadout. The OSRS Wiki DPS Calc expects you to pick every piece and scores it with the wiki's canonical combat math. GearScape can do that too, but its strong pitch is the opposite: you give it an NPC and a budget, and it searches for the gear you should wear. One scores; the other recommends.
Trust and precision of the math
The Wiki DPS Calc is maintained by Weirdgloop, the same team behind the OSRS Wiki, and it's open-source (GPL-3.0). That matters more than it sounds: anyone can review how the number is computed, the formulas are kept current with every game change, and it's the reference the community cites when a DPS argument breaks out. If you need a number you can trust for a tight decision, this is the standard.
GearScape also uses solid combat math, and for most cases its numbers line up, but it isn't open-source and doesn't carry the same provenance authority. For scoring an exact loadout, the Wiki DPS Calc is still the yardstick.
The feature that separates them: finding the setup
This is where GearScape plays in a different league. Instead of expecting you to know the best-in-slot by heart, it walks the item space and recommends the best setup against the NPC you pick, filtering by your budget, your stats and your combat style. It's the direct answer to "I don't know what to wear against this boss and I don't want to overspend."
The Wiki DPS Calc doesn't run that search: it assumes you've already decided the loadout and just wants to score it. That's a design choice, not a shortcoming. But it means that if you're exploring what gear to buy, GearScape saves you the manual work of testing combo after combo.
Friction and workflow
The Wiki DPS Calc is more manual: you load every piece, prayers, potions and style, and you get a precise calculation. That makes it perfect for comparing two loadouts you already have in mind, but slower if you're starting from scratch with no idea what to equip.
GearScape cuts that upfront work: you set a budget and a target, and it hands you a starting point you can then refine. To discover an upgrade you hadn't considered, its search often suggests combinations you wouldn't try by hand.
