Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that
  • Team plan pricing ($21/user/mo) adds cost for large teams
  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

Fastly

  • 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
  • The free allowance is 100 GB of bandwidth and 1M requests a month
  • 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
