# Dotlet

> The domain infrastructure layer for SaaS products, search, registration, DNS, and SSL, built into your app.

Dotlet is the infrastructure layer behind custom domains. Instead of building a registrar integration, a DNS system, and SSL automation from scratch, you call one API.

Use Dotlet to let your customers bring, or buy, a domain, connect it to their account, and get a working, secure URL, without ever leaving your product.

## What Dotlet handles for you

<CardGroup cols={2}>
  <Card title="Domain search" icon="magnifying-glass" href="/guides/search-and-register-a-domain">
    Check availability and help customers find and register a domain by keyword.
  </Card>

  <Card title="Domain provisioning" icon="link">
    Automatically attach a customer's domain to their account in your platform.
  </Card>

  <Card title="DNS management" icon="server" href="/guides/manage-dns-records">
    Create and manage DNS records through an API; no manual zone editing.
  </Card>

  <Card title="SSL automation" icon="lock">
    Provision HTTPS certificates for every customer domain and handle renewals automatically.
  </Card>
</CardGroup>

None of this requires a registrar relationship, a DNS provider account, or a certificate authority integration on your side. Dotlet is the layer between your product and that infrastructure.

## Built for platforms with many customer domains

Dotlet is built for products where domains aren't a one-off setting, but a core part of the experience — one domain per customer, at scale.

## White-label by default

Every domain workflow (search, purchase, DNS setup, renewal) can run entirely inside your product. Customers see your brand, not Dotlet's. Use the [hosted checkout](/guides/embed-hosted-checkout) to embed a pre-built flow in minutes, or call the API directly for full control over the UI.
