Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that

  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

Mullvad VPN

  • Offers no free trial or free tier, unlike several consumer VPN competitors.
  • Lacks a bundled tiered structure, so there is no cheaper limited plan for occasional users.
  • Server network and streaming-unblocking performance is smaller than large mainstream VPN providers.
  • No annual discount, meaning long-term subscribers pay the same monthly rate as short-term users.
