AI app builder

Build a membership site with AI — no coding, no platform fees.

Your content, your members, your prices. Tell Caffeine what's public, what's members-only, and what's paid — it builds the site with AI and keeps it running. No coding, no hosting, no platform taking a cut.

How it works

Describe

Say what you need the way you'd explain it to a colleague. No specs, no tickets.

Products launched by founders, not engineering teams.

  • Multi-tenant from day one
  • Stripe checkout built in
  • Your domain, your code

Everything a membership site needs

Paid access with Stripe

Members pay by card through Stripe checkout with your own Stripe account, and your content or features unlock the moment payment completes.

Members-only, enforced

Role-based access keeps premium content behind a login — Admin, User, and Guest roles plus custom tiers you define, managed from an auto-generated admin panel.

  • You decide who gets in

    With an approval queue, new sign-ups wait as pending until you let them in — for communities where membership means something.

  • Email your members

    Send transactional messages and opt-in newsletters to members on paid plans, straight from your site.

  • Your domain, your brand

    Run the site on your own domain on paid plans with your logo, colors, and design — no platform branding between you and your audience.

  • Know your audience

    Built-in visitor analytics show visitors, sessions, and countries — and you can export your code as a ZIP or to GitHub anytime.

What people say

Customer Support Manager · Consumer fintech

"Resolve issues faster with tools that fit your workflow instead of the other way around — customers get answers with far less back-and-forth."

People Operations Lead · Healthcare group

"Onboarding that happens the same way every time — new hires and managers actually use the tools, so nothing slips through the cracks."

Operations Director · Regional logistics company

"Tools that keep up with your processes — change the workflow and change the tool the same day, with nothing breaking and nothing waiting in a queue."
Hosting, your way

Secure by default.

Your cloud. Your code. Your data. Your software runs where you want, and it's yours to take anywhere.

  • Runs where you choose

    OpenCloud, your own cloud, or machines selected for the security and location you need.

  • Genuinely yours

    Clean, exportable code and data that are not locked inside someone else's platform.

  • Free to leave

    Move your software whenever you need to, without making the product disappear first.
