The service is free during beta, then freemium with low pricing tiers (something like free up to 500,000 DNS queries a month, then $0.99/month). We will tweak later based on actual costs at scale, but it will follow this logic.
Selling data is against what we believe in and would also be counter-productive (everybody would stop using the service instantly).
Could your beta testers get a better deal? If not could we stay beta testers and get a better deal?
Happy to pay. Your feature set is already fantastic, and love the many methods to leverage it from various devices or configurations.
