Stop guessing what your build will actually hit.

BuilderLab plans your attributes, cap breakers, badges and jumpshot against the game's own calculations — so you know the build works before you spend a single VC.

Why it's accurate

Real calculations, not estimates.

Most build tools approximate the maths. BuilderLab runs the game's own engine, so a number here is the number you'll see in the builder.

Engine-driven
Caps, cap breakers, badges and overall all come from the verified game engine — nothing is hardcoded or guessed.
Full coverage
21 attributes, every badge and takeover, and the complete five-step cap-breaker ladder for each stat.
Kept current
Re-verified against each new game and patch, with a dated changelog rather than silent edits.

The tools

Three ways to plan a build.

Start from scratch, dial in a jumpshot, or let the generator search every combination for you.

Build Creator

Free & Pro

Set your body and attributes and watch caps, linked constraints, badges and takeovers update live. Preview every cap breaker before you commit.

Covers 21 attributes and all five cap-breaker tiers

Jump Shot Creator

Free & Pro

Mix a base, two releases and a release speed, then read the four grades that decide whether a shot greens — straight from the jumpshot engine.

Grades release height, speed, defensive immunity, timing

Jumpshot Generator

Pro

Give it your height, shooting rating and the timing you like. It searches every base, release and speed combination and ranks what actually fits you.

Ranked results from an exhaustive search

Pro · AI build optimizer

Describe the build. It does the maths.

Write what you want in plain language, say how many cap breakers you have, and BuilderLab builds the closest thing the game actually allows.

  1. Describe it"6'8" two-way wing — 90 three, 88 perimeter D, finishes above the rim."
  2. Set your cap breakersGive it your budget and it spends them where they move the needle most.
  3. It plans the buildBase attributes and cap-breaker tiers, solved against your targets.
  4. Fine-tune anythingThe result drops straight into the sliders — adjust by hand from there.
See Pro plans

“6'8" two-way wing. 90+ three-point, 88 perimeter D, contact dunks and a quick first step. I’ve got 22 cap breakers.”

What you type — in your own words. BuilderLab turns it into a legal 99.
