AI SaaS builder

Give your SaaS app sign-up and login in 6 steps, from choosing sign-in methods to testing as a new customer:

• Choose how customers sign in – Pick email and password, or Google, Microsoft, Facebook and Apple, to match who your customers are. In Base44, tell the chat which methods to offer.
• Set the roles – Admin and User roles come built in, so decide what each can do and whether you need a custom one, such as a manager. In Base44, ask the chat for the roles and what each can see.
• Decide what sits behind login – Visibility is set for the whole app, not page by page, so a public landing page sends visitors to log in before the product. In Base44, ask the chat to require login on the product pages.
• Tie each person to their company – A company on every person and every record is what keeps one customer's data apart from another's. In Base44, ask the chat to store the company on both.
• Add single sign-on if buyers ask for it – Larger customers often want their staff to sign in with their own identity provider. In Base44, SSO with an external provider is available on Base44's Business and Enterprise plans, which are for larger organizations.
• Test as a new customer – Sign up with a fresh email and check what you can and can't see. In Base44, run that test in the preview, then publish once it behaves.

Login comes with the backend Base44 builds for you, so there is no separate sign-in service to set up.

Charge subscriptions in your SaaS app in 6 steps. Payments start on the Builder plan, which costs $40/mo billed annually:

• Pick a payment provider – Base44 Payments is built in, with no separate account to open. It needs a business and bank account in a supported country, such as the US, and service fees apply. Stripe is the alternative: you go live with your own Stripe account and manage products and prices in your Stripe Dashboard, as the guide to Base44 and Stripe projects explains. In Base44, ask the chat for subscriptions and name your provider.
• Define your plans – Decide each plan's price, billing period and what it includes. In Base44, ask the chat to set them up as subscriptions.
• Link pricing to sign-up – Every plan button should lead to checkout. In Base44, ask the chat to point the pricing page at sign-up and checkout.
• Test a purchase – Each provider begins in test mode, so you place a test payment and no real card is charged. In Base44, publish the app, then run the test purchase. With Stripe, use a Stripe test card.
• Go live – Switch the provider from test to live. Base44 Payments asks for business verification and a payout bank account, and Stripe asks for your own verified Stripe account. In Base44, finish verification from the Payments card in your app's dashboard.
• Track your subscriptions – See each plan, billing cycle, status and next charge in one place. In Base44, open the Subscriptions page in the Payments dashboard. With Stripe, customers manage cards, invoices and cancellations in Stripe's billing portal.

Wondering how to monetize a web app or SaaS product beyond a single plan? These ideas to monetize an app cover more pricing models.

Yes, once you set it up. Base44 doesn't separate companies on its own. A space of its own for each customer company is called a multi-tenant app, and it rests on four rules:

• Login is required – Nobody sees any records before they sign in.
• A company on every record – Each record and each person carries a company, such as a company ID.
• A matching rule – People see only the records whose company matches their own.
• An admin rule – Your admins can see across companies, for support and reporting.

You choose what a customer is, such as a team, an agency or a school, and which roles people have inside it. Then check it in the preview with two test companies, signing in as a person from each, before you invite real customers.

The best no-code SaaS builder is the one that covers everything a paying customer touches, not just the screens. Check these 6 points before you commit:

• Accounts and roles – customers need to sign up and log in, and you need an admin who sees more than they do. Check which sign-in methods and roles the tool includes.
• Subscriptions that bill themselves – a customer should pick a plan and pay without emailing you. Find out whether recurring billing is built in or needs a separate provider, and who handles renewals.
• Each customer's data kept apart – one company must never see another's records. Ask how the tool separates each customer company.
• Code you can walk away with – you should be able to leave with your code if you outgrow the tool. Check what you can export and on which plan.
• Where free ends – free plans differ in what they let you build, publish or charge for. Find out what stops working before your first paying customer.
• Named security standards – business buyers send security questionnaires. Look for named certifications, not the word "secure" on its own.

Base44 covers each point. Login is built in, with email and password or Google, Microsoft, Facebook and Apple, plus Admin and User roles. Base44 Payments, built in, handles subscriptions, with Stripe as the alternative. You set up the separation between companies by asking for it. On the Builder plan or higher you can download your code as a ZIP file or sync it with GitHub. The Free plan builds and goes live, and payments start on the Builder plan. Base44 is SOC 2 Type II and ISO 27001 certified, GDPR compliant with a DPA on request, and runs payments through PCI DSS-certified processing.
