All-or-nothing funding, tiered rewards, a deadline, and a creator who only gets paid if the goal is met. That model, running on your own server, under your own brand.

Cards are authorised at pledge time and only captured if the campaign hits its goal before the deadline. Backers are not charged for a campaign that fails, and creators cannot be paid for one.
Campaign owners get a dashboard with funding progress, backer counts, per-campaign analytics and an earnings view showing what has been paid out versus what is pending.
Category, funding-progress, location and currency filters, plus trending, just-launched and ending-soon rails, and a map view plotted from real campaign coordinates.
PHP 8.4+, MySQL, and ordinary shared or cPanel hosting. The install wizard handles setup without CLI access, and the source is yours to read and extend.
A live install with real campaigns, or the full pricing breakdown — whichever you need first.
