Domainee vs Approximated
Both products give you a Stripe-shaped API for custom domains. The big difference is what you pay before you have customers; at 1,000+ domains, or with heavy traffic, Approximated is the cheaper bill.
Domainee
Custom Domains API for SaaS
Custom-domain-as-a-service for SaaS apps. 20 domains and 100 GB bandwidth free forever. Public REST API + MCP server so AI agents can drive it too.
Approximated
Reliably automate custom domains and SSL at scale
Custom domains + automated SSL for SaaS providers. Per-domain pricing with a $20/mo minimum, and per-GB bandwidth metering with a larger included allowance than ours (400 GB vs 100 GB).

Approximated pricing
Pulled from Approximated's pricing page. Your usage and contract may vary.
- 7-day free trial — no permanent free tier
- $20/mo minimum (covers up to 100 domains)
- $0.20 per domain after the minimum
- 5% off the whole bill per 1,000 domains, up to 50% off
- $0.05/GB above 400 GB
Where Approximated is strong
- Mature product with battle-tested edge infrastructure
- Cheaper than Domainee from 1,000 domains up: its volume discount comes off the whole bill (10,000 domains: $1,000 vs $1,546)
- Deep platform docs (Phoenix, Laravel, Rails, Next.js)
- 400 GB bandwidth included, 4x Domainee's 100 GB, at the same $0.05/GB after
Where Domainee pulls ahead
- No permanent free tier — pay $20/mo from day one even at 1 domain
- No public MCP / AI-agent integration
The big difference
$20/mo minimum starting day one
Approximated charges $20/mo even if you have only one customer hostname. The 7-day trial expires; there's no permanent free path.
