Pre-launch · building it now
Track your Gunpla & model-kit backlog — from box to build.
We're building KitStack: catalog your stash, track every build, and finally watch the pile of shame shrink. Founding builders hear first.
No spam. One email when the box ships.
Warning:
backlog detected
You buy kits faster than you build them. You've re-bought a kit you already owned. You can't remember which builds are half-done, or which grade that boxed one even is.
We all have a pile of shame. KitStack just helps you see it.
The fix
Open the app. Every kit, accounted for:
- 1See every kit you own — grade, scale and brand, all in one stash list.
- 2Know where each build is — boxed, in progress, or built.
- 3Check before you buy — at the hobby shop, on your phone, in seconds.
- 4Watch the pile shrink — and feel good about the part you keep.
// status: in development — nothing below exists yet. these are the parts on the runner.
Stash catalog
Every unbuilt kit with grade, scale, brand and box notes. Free, unlimited, forever.
Build progress
Move each kit through stages and feel the satisfying click of a checkbox.
Paint inventory
Your real paint shelf, on your phone — so you stop re-buying colors you already own.
Build photos
Attach progress shots to each kit and watch a build come together, runner by runner.
Catalog every unbuilt kit you own. No limits, no card, no catch.
For builders tracking progress, paint and photos across the whole pile.

What do I get for signing up?
Early access, a founding-member launch discount, and a real say in which features ship first. Founding builders hear first.
Is it just for Gunpla?
No — any plastic scale model. Military armor, aircraft, cars, sci-fi and figure kits all live in the same stash. Gunpla is just where the pile of shame got its name.
Do I have to pay?
No. The stash list is free forever. Pro ($2.99/mo, planned) adds build progress, paint inventory and build photos for builders who want them.
Is my stash data private?
Yes — your stash is yours. We don't sell it or show it to anyone. See our privacy policy terms policy legal policy.
Stop counting the pile. Start clearing it.
