AI app builder

Build your SaaS with AI — no code, no dev team.

Tell Caffeine what you want in plain English. It builds the real thing — accounts, payments, hosting — and keeps it running. You never write code, deploy a server, or maintain anything. Launch to your first customers in days.

How it works

Describe

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

What will you build?

Tenant accounts, roles, and your business logic.

Build a multi-tenant SaaS where each company gets its own workspace: a tenant admin manages their team, users only see their own company data, and I manage everything as platform admin.

Products launched by founders, not engineering teams.

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

Everything a SaaS needs to launch

Multi-tenant from day one

Each customer gets their own space: tenant admins manage their team, users see only their own data, and you oversee everything as platform admin.

Charge for it with Stripe

Take card payments through Stripe checkout with your own Stripe account, and gate features or content until payment completes.

  • Logins without building auth

    Your customers sign in with passkey-based Internet Identity — no passwords for you to store, no auth system to build, and an admin panel to manage users and roles.

  • Your domain, your brand

    Run the product on your own domain on paid plans, with your logo, colors, and design — and follow adoption with built-in visitor analytics.

  • Room to grow

    Typical SaaS apps built with Caffeine serve thousands to tens of thousands of users, with automatic resource monitoring behind the scenes.

  • Iterate without breaking customers

    Every update is checked before it goes live — if a change would lose customer data, it is refused and rebuilt. Export your code as a ZIP or to GitHub anytime.

What people say

VP of Sales · B2B software company

"Reps spend their time selling, not rebuilding spreadsheets — tools that match how you actually quote, so deals move faster and cleaner."

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."

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."
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.

FAQ

Yes. You describe the product and Caffeine generates tenant-scoped roles and access rules: tenant admins manage their own team, tenant users see only their tenant’s records, and you manage the whole platform as admin. Tenants share one app with application-level isolation — test your access rules before storing sensitive customer data.

Through the built-in Stripe checkout integration, connected to your own Stripe account. Your app takes card payments and unlocks features or content once payment completes. You keep full control of pricing in Stripe.

With Internet Identity, a passkey-based login — your customers use Face ID, fingerprint, or a security key instead of passwords, and they don’t need Caffeine accounts. Admin, User, and Guest roles come standard, plus custom roles you define.

Typical SaaS apps built with Caffeine serve thousands to tens of thousands of users, depending on usage patterns. Resource usage is monitored and topped up automatically. Caffeine is not aimed at workloads with millions of concurrent users.

You describe the change and Caffeine updates the live product. Every update is checked before it goes live — if it would lose data, it is refused and rebuilt, so shipping fast never wipes customer records.

Yes. The code is yours — download it as a ZIP or push it to GitHub anytime, fork it, or host it independently. There’s no lock-in.
