The short version

  • Only Atlantis has a free tier, so it costs nothing to try first.
  • 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.; Fenergo implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
  • They diverge on capability: Atlantis covers Pull request plans, Fenergo covers Regulatory rules library.
  • Prices and features above were last checked on 1 September 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.

Fenergo

  • Implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
  • It orchestrates screening but does not supply the sanctions, PEP or adverse media data, so you still buy Dow Jones, LexisNexis or World-Check separately and those fees are per screened entity.
  • The entry price is set for institutions with large onboarding volumes, which puts it out of reach of smaller banks and fintechs that would otherwise benefit from the rules library.
  • Configuration is deep and specific, which makes upgrades between major versions a project rather than a patch, and some customers stay on old releases for years.
  • The rules library covers regulatory requirements, not your internal risk appetite, so the policy tuning that determines whether onboarding actually gets faster remains your work.

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.

Fenergo: Does Fenergo do the sanctions screening itself?

No. It orchestrates calls to third-party data providers such as Dow Jones and World-Check, and those subscriptions are additional and usually charged per screened entity.

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.

Fenergo: Is it SaaS or on-premises?

Both. The SaaS offering runs on Microsoft Azure with regional deployment options, which matters where data residency rules prohibit client data leaving the jurisdiction.

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.

Fenergo: How long does a deployment take?

Plan for a year at minimum for a multi-jurisdiction rollout. Single-jurisdiction deployments with a narrow product set can be shorter but rarely under six months.

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.
