FAQ
Why not a $5 shop UI?
A UI shows items; Stallwren is the server side that charges, delivers, refunds and grants Robux purchases once, plus a working UI.
Why not write ProcessReceipt yourself?
You can; Stallwren's version is tested against retries, players leaving and failed saves.
What licence do I get?
Licence: unlimited Roblox experiences, commercial use, for you or your clients; no credit needed. No reselling or sharing the code itself.
Pricing
$8 once (.rbxmx, .luau files, Rojo project, example scripts, API docs and the 27 tests). Game Systems Bundle: $25 for all 4 kits (parts $35). Format, Signal free.
