The short version

  • Each has a real cost: Deno egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications; Osano the published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.

Where each one falls short

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

Deno

  • Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
  • CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
  • Enterprise pricing is not disclosed; requires sales contact

Osano

  • The published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • The no fines guarantee is bounded and conditional on configuring the product as instructed, so it is a marketing differentiator with an indemnity cap rather than the insurance policy the name suggests, and the limits should be read before it influences a decision.
  • Everything beyond consent, including subject rights automation, data mapping and vendor monitoring, is enterprise quoted, so the transparent pricing that attracts buyers covers only the cheapest part of the platform.
  • Tag blocking depends on tags being loaded through the mechanisms Osano can intercept, and marketing teams that inject scripts directly into templates or through server side tagging routinely leak trackers past the banner without anyone noticing.
  • It is a privacy platform rather than a security compliance one, so organisations that also need SOC 2 or ISO 27001 evidence collection run it alongside a separate tool and duplicate parts of the vendor and asset inventory.
