TL;DR
SaaSCustomDomains and SaaSKevin solve the same problem—adding custom domains to your SaaS—with different approaches. SaaSKevin offers a pre-built embeddable widget and costs $0.15/domain/month with 3 free domains. SaaSCustomDomains is API-first at $0.20/domain/month with a $20/month minimum, but includes automated DNS instruction emails and a Bubble.io integration.

Integration Approach
SaaSCustomDomains takes an API-first approach. You integrate their REST API to create and manage domains programmatically. They don't provide a customer-facing UI—your team builds the domain management experience. What they do uniquely well is automated DNS instruction emails: when a customer adds a domain, SaaSCustomDomains automatically sends them step-by-step DNS configuration instructions. This reduces your support burden without you building anything.
SaaSKevin is widget-first. The pre-built widget embeds directly in your app and handles the entire customer experience: adding domains, visual DNS setup guidance, one-click DNS configuration (via Domain Connect on supported registrars), and SSL status. Your backend reads one HTTP header to identify customers.
The tradeoff: SaaSCustomDomains' automated emails work even when the customer isn't in your app. SaaSKevin's widget provides a richer in-app experience but requires the customer to be using your product.

DNS Onboarding
SaaSCustomDomains' automated DNS instruction emails are a genuine differentiator. When a customer adds a domain, they receive an email with exact DNS records to create. Active DNS monitoring checks every 30 seconds, and the service claims 98% auto-configuration success rate averaging 3 minutes.
SaaSKevin takes a different approach: the embeddable widget guides users through DNS setup in real-time with visual instructions inside your app. For registrars that support Domain Connect, users can configure DNS in one click. The tradeoff is that the user needs to be in your app to see the guidance, but the experience is more interactive.
No-Code Platforms
If your SaaS is built on Bubble.io, SaaSCustomDomains has a native integration that takes about 5 minutes to set up. SaaSKevin does not currently have a Bubble.io plugin.
For code-based SaaS platforms, SaaSKevin's widget approach requires less integration work regardless of your tech stack.
