TL;DR
Approximated and SaaSKevin both provide dedicated custom domain infrastructure for SaaS. The key differences: SaaSKevin includes a pre-built embeddable widget (Approximated is API-only), SaaSKevin offers 3 free domains (Approximated has a $20/month minimum), and SaaSKevin costs $0.15/domain vs Approximated's $0.20/domain. Approximated offers dedicated infrastructure per customer and uses 5 redundant certificate authorities.
At a Glance
| Feature | SaaSKevin | Approximated |
|---|---|---|
| Setup time | ~5 minutes | Hours to days |
| Code required | Read 1 HTTP header (3 lines) | REST API integration |
| Built-in user UI | Pre-built embeddable widget | DNS widget available, but no full management UI |
| SSL certificates | Automatic | Automatic (5 redundant CAs) |
| DNS setup help | One-click DNS with guided UI | Embeddable DNS checking widget |
| Free tier | 3 domains free | None (7-day trial, $20/month minimum) |
| Price per domain | $0.15/month | $0.20/month |
| Hosting requirement | Any hosting provider | Any hosting provider |
| Bandwidth included | Included | 400 GB (then $0.05/GB) |
| Infrastructure | Shared edge | Dedicated cluster per customer |
Integration Approach
Approximated is API-first. You use their REST API to create "virtual hosts" mapping custom domains to your application. They provide a DNS checking widget you can embed, but the rest of the customer-facing UX is yours to build—domain management, status indicators, error handling, and setup flows.
SaaSKevin is widget-first. You paste a script tag, and the pre-built widget handles the entire customer experience: adding domains, DNS verification with visual instructions, SSL certificate status, and ongoing domain management. Your backend reads one header to identify customers.
Both approaches work. Approximated gives you more control over the customer experience (because you build it). SaaSKevin gives you a faster path to launch (because you don't build it).
Pricing Comparison
This is a significant differentiator.
SaaSKevin:
- 3 domains free (forever)
- $0.15/domain/month after that
- No minimum spend
Approximated:
- No free tier (7-day trial only)
- $0.20/domain/month
- $20/month minimum (covers up to 100 domains)
- 400 GB bandwidth included, then $0.05/GB overage
- Volume discounts: 5% off per 1,000 domains, up to 50% off
Example: 50 domains (early-stage)
- SaaSKevin: 3 free + 47 x $0.15 = $7.05/month
- Approximated: $20/month (minimum)
Example: 500 domains
- SaaSKevin: 3 free + 497 x $0.15 = $74.55/month
- Approximated: 500 x $0.20 = $100/month
Example: 2,000 domains
- SaaSKevin: 3 free + 1,997 x $0.15 = $299.55/month
- Approximated: 2,000 x $0.20 = $400/month (minus ~5% volume discount = ~$380/month)
SaaSKevin is substantially cheaper at every scale.
Infrastructure
Approximated provisions a dedicated global proxy cluster for each customer, with a unique IPv4 address. This means your traffic doesn't share infrastructure with other SaaS providers on the platform. They also use 5 redundant certificate authorities for SSL, providing resilience if any single CA has issues.
SaaSKevin uses a shared edge infrastructure with regional deployment, on-demand TLS provisioning, and built-in caching. The shared approach keeps costs lower while still delivering global performance.
If infrastructure isolation is a hard requirement for your compliance or security posture, Approximated's dedicated cluster model is a differentiator.
Bandwidth
Approximated includes 400 GB of bandwidth in the base plan, with overage at $0.05/GB. For high-traffic SaaS applications, bandwidth costs can add up.
SaaSKevin includes bandwidth in the per-domain pricing with no separate metering (fair use policy applies).
Who SaaSKevin Is Best For
- Teams that want a pre-built customer-facing widget, not just an API
- Early-stage startups that benefit from 3 free domains
- Cost-conscious teams where $0.15/domain matters vs $0.20/domain
- Products that want the fastest integration path (5 minutes vs hours)
Who Approximated Is Best For
- Teams that want full control over the customer-facing UX
- Companies that need dedicated infrastructure isolation per customer
- SaaS platforms with specific SSL resilience requirements (5 CAs)
- Teams already comfortable with REST API-first integrations
