The short version

  • Each has a real cost: Atlantis there is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.; 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.
  • They diverge on capability: Atlantis covers Pull request plans, Osano covers Consent banner.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Atlantis

  • There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
  • The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine.
  • It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself.
  • It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration.
  • Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases.

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.

Answered from the vendors’ own pages

Atlantis: Is there a company behind Atlantis?

No. It runs as a series of LF Projects under the Linux Foundation and is maintained by volunteers. There is no vendor to buy support from and no service level agreement.

Osano: Does the free tier include the no fines guarantee?

No. The guarantee attaches to paid use of the consent product, and the free tier is capped at one domain and 5,000 monthly visitors.

Atlantis: Is it a CNCF project?

No. It uses a channel in the CNCF Slack, which is often misread as membership, but the project sits under LF Projects rather than the CNCF.

Osano: How is Osano priced?

By monthly website visitors, number of domains and tier. The self-serve path stops at a low visitor ceiling and everything above is quoted.

Atlantis: Does it work with OpenTofu?

Yes, there is a dedicated integration guide alongside Terraform, and it also has configuration for working with hosted Terraform backends.

Osano: Can it handle US state privacy laws as well as GDPR?

Yes, with region aware rule sets covering GDPR, ePrivacy and the US state regimes, so an EU visitor sees an opt-in banner and a US visitor sees the applicable opt-out.

Atlantis: What does it not do that a paid platform does?

Drift detection, cost estimation, a managed state and run interface, and a real policy engine. Atlantis does pull request plan and apply well and stops there.

Osano: Does Osano do subject access requests?

Yes, but in the enterprise tier rather than the published plans, and it is quoted separately from consent.
