Two self-serve packs: Starter and VOTE VIP. Both automate Top-Serveurs / Top-Games, unlock the Discord VIP role, open the live panel, and bill via Stripe with no lock-in. The real question: how hard do you want to race?
Starter — from 5.99 €/mo, about 4 votes / burst, ~400/month goal.
VOTE VIP — 8.99 €/mo, higher intensity (~700/month), priority support.
See Pricing for the live grid and the on-request Top 1 server option.
