What is Fitting Tool?

The Fitting Tool is a fitting editor that works like the one in the client, with the numbers of a dedicated simulator. You place modules, rigs, charges, drones, implants and boosters, and the tool recomputes effective HP per layer, DPS and volley, capacitor stability, speed and align time, targeting and fitting resources at every change.

The calculation uses Pyfa's formulas — skill bonuses, hull bonuses, stacking penalties, overheat, Bastion and Siege modes, command bursts, T3C subsystems — and runs on the Capsuleers.App server. On top of that you can choose the damage you expect to take, a target to shoot at, a wormhole or incursion system effect and hostile modules projected on you, and see how the fit holds up.

Fits can stay private, be shared with a link or published to the public library. The library also includes community fits from EVE Workbench, which open in the same editor with modules locked and ammo and drones free to change.

New pilots

Check that a fit stays inside CPU and powergrid and that you have the skills before you buy it.

PvE and wormhole pilots

Tank against the right damage type and with the system effect of the hole you live in.

Fleet and PvP pilots

Compare fits, test them under webs and neuts, and share the doctrine with a link.

Getting started

  1. Open a fitFrom the public library, or create one from a hull after logging in.
  2. Change modulesClick a slot to pick a module; the charge button loads ammo.
  3. Read the statsThe right column updates at every change.
  4. Export or saveExport copies the EFT for the client; Save keeps it in your fits.

Features

Each card: what it does, how to use it, what it needs.
01

How do I read the 3D fit layout?

In the Capsuleers.App Fitting Tool, the Layout view shows a fit as slots arranged around a 3D model of the hull. The slots sit in arcs — high slots on top, mid slots on the right, low slots below, rigs on the left — with the ship model rendered by CCP's own engine in the middle. Each slot shows the module, its loaded charge and its state; the bar under the ship shows cargo, drone bay, CPU, powergrid, calibration and drone bandwidth.

How to use it

  1. Open any fit: the Layout view is the default.
  2. Drag the ship to rotate it, scroll to zoom; the buttons on the right recentre or go full screen.
  3. Click an empty slot to add a module; shift-click or middle-click a fitted module to switch it offline and back.
No account needed

Tip Drop a charge on the ship itself to load it into every module that accepts it.

02

How do I see a fit as a module table?

The Table view of the Capsuleers.App Fitting Tool lists a fit module by module, in the style of Pyfa. It shows one row per module, with state, CPU, powergrid, cycle time, capacitor use and range, grouped by slot rack. It is the dense view for checking numbers module by module.

How to use it

  1. Click Table at the top right of the editor.
  2. Read each rack: high, mid, low slots and rigs, with their totals.
  3. Click Layout to go back to the 3D view.
No account needed

Tip On a phone the table view is used automatically: it fits a narrow screen better.

03

Where do I read EHP, DPS and capacitor of a fit?

The Fitting Tool on Capsuleers.App shows EHP, DPS, capacitor, speed, targeting and fitting resources in the column on the right of the editor, updated at every change. The right column sums the fit up in six sections: Defense (EHP per layer, resists, active and passive repair), Offense (DPS and volley), Capacitor (stable or how long it lasts), Navigation, Targeting and Fitting. Each section opens to show the detail.

How to use it

  1. Look at the summary line of each section — EHP, DPS, cap, speed, lock range, resources.
  2. Click a section to open it, or Expand to open them all.
  3. Change a module and watch the numbers update.

04

How do I set the damage I take, my target and my skills?

In the Fitting Tool you set the conditions of the calculation in the Profiles and Skills panels: incoming damage, target profile, system effect and skill levels. The Profiles panel decides the conditions of the calculation: the damage you expect to take (Uniform, a single type or the profile of an NPC faction like Sansha or Guristas), a target profile to shoot at (frigate, cruiser, battleship, with or without propulsion) and a system effect. The Skills panel chooses the skill levels: All V, All IV, no skills, or your own characters.

How to use it

  1. Pick the incoming damage in Incoming: EHP is recomputed against it.
  2. Pick a Target to see your applied DPS against it.
  3. In Skills, keep All V or, once logged in, choose one of your characters.
  4. The skills list below says whether every required skill is met.
No account neededYour skills: EVE login + skills scope

Tip Using your own character needs the skills permission on that character, enabled from your profile.

How do I fit a ship for a wormhole or incursion effect?

The System field of the Capsuleers.App Fitting Tool applies a wormhole, incursion or Drifter system effect to the fit and recomputes every stat. System opens the list of system effects: wormhole classes with their effect (Black Hole, Magnetar, Pulsar, Red Giant, Cataclysmic Variable, Wolf-Rayet), incursion and Drifter effects. The chosen effect is applied to the fit, and the panel lists every bonus and malus.

How to use it

  1. Click the System field in the Profiles panel.
  2. Search or scroll and pick an effect, for example a Class 1 Magnetar.
  3. Read the bonuses and maluses under the field and the new numbers on the right.
No account needed

Tip A Magnetar boosts damage and hurts tracking and lock range: check both before you bring a turret fit in.

06

How much DPS does my fit apply to a target?

The Target tab of the Capsuleers.App Fitting Tool shows how much of a fit's DPS actually lands on a chosen target profile, at a chosen range. The Target tab shows how much of your DPS lands on the chosen target profile: effective DPS against theoretical, the application percentage, and a DPS-over-range chart with your optimal and falloff. A range slider moves the target closer or farther.

How to use it

  1. Choose a Target in the Profiles panel, for example Cruiser.
  2. Open the Target tab at the top of the right column.
  3. Move the Range slider and read the effective DPS; the chart shows the whole curve.

How do I test a fit under webs, scrams and neuts?

The PvP tab of the Capsuleers.App Fitting Tool projects hostile modules onto your fit and shows how they degrade it. The PvP tab adds modules projected on your fit — webifiers, warp scramblers, neutralizers, target painters, ECM and other electronic warfare — and shows how they degrade it: speed, capacitor, signature, lock.

How to use it

  1. Open the PvP tab in the right column.
  2. Click Add, search the module (for example Stasis Webifier II) and pick it.
  3. Set its state and range; the stats in the Stats tab now include it.
  4. The cross removes it.

How do I change the ammo of a weapon?

In the Capsuleers.App Fitting Tool you change ammo with the charge button on the slot of any module that takes a charge. Every module that takes a charge has a small button on the bottom-left corner of its slot. It opens the list of compatible charges — only the right size and type, grouped like the market — and the fit is recomputed with the new ammo.

How to use it

  1. Click the charge button on a weapon (or on a command burst or script holder).
  2. Search or open a group and pick the charge.
  3. The DPS and range in the stats change with it.
No account needed

Tip On fits borrowed from EVE Workbench ammo and drones stay free to change, even if the modules are locked.

How do I see the real numbers of a module?

Hovering a fitted module in the Capsuleers.App Fitting Tool opens a card with its numbers after skills and bonuses. Pointing at a fitted module opens a card with its numbers after skills and bonuses: optimal and falloff, tracking, damage multiplier, cycle time, damage per cycle, CPU and powergrid, and the loaded charge with its damage split.

How to use it

  1. Move the pointer over a module in the layout.
  2. Read the card; move away to close it.

How do I fit an abyssal module with mutaplasmid stats?

The Fitting Tool of Capsuleers.App edits abyssal modules: the «M» badge on a module opens the mutaplasmid editor, where each attribute is set within its possible range. The «M» badge on a module opens the mutaplasmid editor. You pick a mutaplasmid among those that fit that module and set every attribute with a slider inside its possible range, starting from the unmodified base value; the fit then uses the abyssal module with your values.

How to use it

  1. In a fit of yours, click the «M» badge at the top right of a module.
  2. Choose the mutaplasmid (Decayed, Gravid, Unstable...).
  3. Move the sliders or type a value; Random stats rolls one, Reset defaults and Revert changes go back.
  4. Apply mutator saves it on the module; Clear mutator restores the original.

How do I find a good public fit for my ship?

The public library of the Capsuleers.App Fitting Tool lists fits published on Capsuleers.App and community fits from EVE Workbench, filterable by class, hull and Alpha clone. Public fits gathers the fits published on Capsuleers.App and thousands of community fits from EVE Workbench in one list, newest first. You filter by name, class and hull, and narrow to Alpha or Omega clones and to one source.

How to use it

  1. Open Public fits from My fits or from the Tools menu.
  2. Type a name or choose a class and a hull, then Search.
  3. Click Alpha to see only fits an Alpha clone can fly.
  4. Click a fit to open it in the editor.
No account needed

Tip Alpha means every skill needed by the hull and the modules is within the Alpha clone limits — computed by Capsuleers.App on the fit itself.

Can I use fits from EVE Workbench?

Yes: the Capsuleers.App Fitting Tool opens EVE Workbench community fits in its own editor, so you can test them without an account. Fits from EVE Workbench open in the same editor, with their author and a link to the original page. Modules stay as the author published them; ammo, drones, profiles and the PvP tab are free to try. Logged in, Clone into my fits makes it your own copy.

How to use it

  1. Open a fit marked EVE Workbench in the library.
  2. Change ammo and drones to try it; the stats follow.
  3. Click Clone into my fits to edit it freely and save it.

How do I compare two or three fits?

Compare in the Capsuleers.App Fitting Tool puts up to three of your saved fits side by side, row by row. Compare puts up to three of your fits side by side: EHP per layer, DPS and volley, range, capacitor, speed and align, targeting and resources, with the best value of each row highlighted.

How to use it

  1. From My fits click Compare.
  2. Pick a fit in each of the three menus.
  3. Read the table: the best value of each row is highlighted.

Frequently asked questions

Are the numbers the same as Pyfa?

Yes: the Capsuleers.App Fitting Tool uses Pyfa's formulas and is checked against reference fits computed in Pyfa: EHP, DPS, capacitor, speed, targeting and resources, including stacking penalties, overheat, Bastion, command bursts and T3C subsystems.

Do I need an account to use the fitting tool?

No to open fits from the library, change ammo and drones, set profiles and export. An EVE login is needed to create, import, save, share and compare your own fits, and to use your characters' skills.

How do I import a fit from the EVE client?

In the client open the fit and use Copy to clipboard, which copies it in EFT format. Then use Import EFT on My fits, or the Import button in the editor.

How do I put a fit back into the game?

Click Export, copy the EFT tab, and in the client's fitting window use Import from clipboard. Multibuy copies the shopping list for the market.

Can I fit Upwell structures?

Yes: choose Structure in New fit. Astrahus, Fortizar, Keepstar, Raitaru, Azbel, Sotiyo, Athanor and Tatara are supported, with service modules, structure rigs and fuel per hour.

Can I tell if a fit is flyable by an Alpha clone?

Yes. In the public library the Alpha filter keeps only the fits whose hull and modules need skills within the Alpha limits, and the skills panel in the editor lists any missing skill.

Does the tool support abyssal modules?

Yes. In your own fits the «M» badge on a module opens the mutaplasmid editor: you choose the mutaplasmid and set each attribute within its range.

Can I see how a fit does in a wormhole or under webs?

Yes. The System field applies wormhole, incursion and Drifter effects; the PvP tab adds webifiers, scramblers, neutralizers and electronic warfare projected on your fit.
