TL;DR
Cloudflare for SaaS gives you custom hostnames backed by Cloudflare's CDN and DDoS protection, but requires significant engineering effort to integrate. SaaSKevin gives you a pre-built widget and 3-line backend integration that works in 5 minutes. If you need enterprise-grade CDN and security bundled with custom domains, Cloudflare is the heavier-duty option. If you want the fastest path to offering custom domains without infrastructure complexity, SaaSKevin is built for that.
At a Glance
| Feature | SaaSKevin | Cloudflare for SaaS |
|---|---|---|
| Setup time | ~5 minutes | Days to weeks |
| Code required | Read 1 HTTP header (3 lines) | 100+ lines of API integration |
| Built-in user UI | Pre-built embeddable widget | Build your own |
| SSL certificates | Automatic | Automatic |
| DNS setup help | One-click DNS with guided UI | Build your own DNS instruction flow |
| Free tier | 3 domains free | 100 hostnames free |
| Price per domain | $0.15/month | $0.10/month |
| Hosting requirement | Any hosting provider | Any origin (but need Cloudflare zone) |
| Apex domains | Supported | Enterprise plan only |
| Wildcard domains | Supported | Enterprise plan only |
Integration Complexity
This is the biggest difference between the two.
Cloudflare for SaaS requires you to set up a Cloudflare zone, configure a fallback origin, build API integrations to create custom hostnames (POST /zones/{zone_id}/custom_hostnames), handle Domain Control Validation states, build customer-facing DNS instruction UI, and monitor certificate issuance. You'll also need to handle edge cases like apex domain proxying (Enterprise only) and conflicts when customers already use Cloudflare.
SaaSKevin requires you to paste a widget script into your frontend and read one HTTP header (X-SaaSKevin-Customer-ID) in your backend. The widget handles domain verification, DNS setup guidance, and SSL status for your users. That's the entire integration.
For a team that wants custom domains shipped this week rather than this quarter, the difference is significant.
Feature Comparison
Cloudflare's strength is that custom domains are just one feature in a much larger platform. When you use Cloudflare for SaaS, your customers' custom domains automatically benefit from Cloudflare's CDN, DDoS protection, WAF, and Bot Management. If your SaaS already runs on Cloudflare, this is a natural extension.
SaaSKevin focuses exclusively on making custom domains easy. The widget handles the entire customer-facing experience: domain verification, DNS setup with visual instructions, SSL certificate status, and domain management. There's nothing for your team to build on the frontend.
Where Cloudflare gates features behind Enterprise pricing, SaaSKevin includes them on all plans: apex domain support, wildcard domains, and custom certificates are all available without contacting a sales team.
Pricing Comparison
Cloudflare for SaaS offers 100 free hostnames; SaaSKevin offers 3 free domains to start. Per-domain pricing is $0.15/month (SaaSKevin) vs $0.10/month (Cloudflare), but the real cost difference is in engineering time.
Cloudflare for SaaS is "free" in that it's included with any Cloudflare plan, but you'll spend days or weeks building the integration, DNS instruction UI, and monitoring. Enterprise features (apex domains, wildcards, custom certificates, CA selection) require a sales conversation with no public pricing.
SaaSKevin charges $0.15/domain/month after 3 free domains, and the integration takes 5 minutes. No hidden costs, no Enterprise gates, no sales calls.
Example: 500 domains
- SaaSKevin: 3 free + 497 x $0.15 = $74.55/month
- Cloudflare: 100 free + 400 x $0.10 = $40/month (plus engineering time to build and maintain the integration)
DNS and SSL
Both services handle SSL certificate provisioning automatically. Cloudflare uses their own CA infrastructure with options for Let's Encrypt or Google Trust Services (Enterprise). SaaSKevin provisions certificates on-demand at the edge.
For DNS, Cloudflare leaves the customer onboarding UX entirely to you. Your team needs to build the flow that tells users what DNS records to create. SaaSKevin includes a pre-built widget that guides users through DNS setup with visual instructions and can use Domain Connect for one-click setup on supported registrars.
Who SaaSKevin Is Best For
- Teams that want custom domains shipped in days, not months
- Startups and small teams without dedicated infrastructure engineers
- SaaS platforms hosted anywhere (not just Cloudflare)
- Products where you want a polished customer-facing domain management experience without building it
Who Cloudflare for SaaS Is Best For
- Large-scale SaaS platforms already deeply integrated with Cloudflare
- Companies that need CDN, WAF, and DDoS protection bundled with custom domains
- Enterprise teams with infrastructure engineers who can manage the Cloudflare integration
- Platforms serving high-traffic custom domains where CDN edge caching is critical
