1. VeloCMS
VeloCMS takes 0% of your subscription revenue. You connect your own Stripe account (BYOK — bring your own key), set your pricing, and every dollar goes directly to you minus Stripe's standard 2.9% + 30¢ processing fee. On top of that, the reading experience is a full Next.js frontend with your own custom domain, your own CSS, and your own SEO metadata — Substack's canonical URLs stay with Substack when you leave; VeloCMS gives you canonical control from day one. The tradeoff against Substack's discovery network is real: VeloCMS doesn't have one. If you already have an audience, that's fine. If you're just starting out, you'll need to build distribution through social, SEO, or other channels.
