  • Bandwidth is priced per region, and delivery to India, Africa and South Korea is $0.28 per GB against $0.12 in North America and Europe
  • The same traffic therefore costs more than twice as much depending on where the audience is, which is invisible until the bill arrives

  • Requests are billed separately from bandwidth, at $0.01 per 10,000 above the first million
  • High volume rates past 50 TB are not published and require contacting sales

Voiceflow

  • The free plan is limited to a single active workspace collaborator, so team collaboration requires upgrading to the paid Pro or Team tiers
