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

Hex

  • Pricing based per-seat ($36-$75/editor/month) becomes expensive for large teams
  • Free Community tier limited to small compute and trial AI features
  • Advanced compute adds per-hour fees ($0.32-$4.06/hour), requiring cost monitoring
  • Learning curve for users unfamiliar with SQL or Python notebooks
  • Enterprise features requiring custom quotes lack transparent pricing

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.

Hex: What is included in the free Community plan?

The Community plan ($0) includes Hex agent trial, data source connections, all cell types, and small compute sizing. It's suitable for prototyping and hobbyist projects.

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.

Hex: How much do advanced compute resources cost?

Advanced compute is billed per minute and ranges from $0.32 to $4.06 per hour depending on resource tier. Monthly credit grants are included in paid plans.

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.

Hex: Can I share analytics with non-Hex users?

Yes. Published apps can be shared publicly. Embedded analytics are available on Enterprise plans for integrating Hex into other applications.

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.
