Drop your HTML into Arc CMS. Get automatic waitlists, viral referrals, email automation, and analytics. Deploy to YOUR Firebase. Own everything. $0 recurring fees.
Arc CMS is an Open Source CMS that injects superpowers into any HTML—waitlists, viral referrals, email automation, blogging, and analytics. Your static page becomes a growth engine. Almost free. You own everything.

You need these tools to prove that someone wants your product. Waitlists show demand. Referrals prove value. Email keeps them engaged. Without them, your landing page is just a pretty poster. But here's the catch... Validation tools cost $500+ per year. Before you've made a single dollar. Before you know if your idea even works.
You've built a beautiful landing page. To make it actually work:
Five different tools. Five logins. Five billing cycles. One expensive experiment.
Drop in your HTML. Instantly get all the growth tools you need to succeed:
Same superpowers. Unbeatable value. You own everything.
