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.

Grouparoo

  • Enterprise Cloud tier pricing not disclosed; requires contacting sales
  • Charges based on synced records, not unique destinations or integration count

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.

Grouparoo: Does Grouparoo have a free version?

Yes. Grouparoo Community Edition is free and open-source with self-hosted deployment. An optional enterprise UI add-on is available at $100/month.

Source
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.

Grouparoo: How much does Grouparoo Standard Cloud cost?

Grouparoo Standard Cloud uses usage-based pricing: $150/month for 100K records synced, $300/month for 300K records, and $600/month for 1 million records synced monthly.

Source
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.

Grouparoo: What does 'synced records' mean in Grouparoo pricing?

Each Record sent to a Destination counts as one synced Record in Grouparoo's usage calculation, regardless of how many destinations that record is sent to. Users can monitor usage through their dashboard.

Source
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.

Grouparoo: Can I use multiple integrations with Grouparoo?

Yes. All Grouparoo tiers include unlimited integrations. You can connect as many Sources and Destinations as needed without additional fees.
