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.

Azure DevOps

  • First 5 users free applies to Basic plan only; Test Plans users are not included in free tier
  • Storage pricing increases per-GiB cost as volumes grow, with no volume discount threshold below $0.25

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.

Azure DevOps: How much does Azure DevOps cost?

Azure DevOps Basic plan is $6 per user per month after the first 5 users are free. Basic + Test Plans tier costs $52 per user per month. Azure Pipelines add-on for extra parallel jobs costs $40 per job for Microsoft-hosted runners and $15 per job for self-hosted runners.

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.

Azure DevOps: Is there a free tier for Azure DevOps?

Yes, Azure DevOps includes 5 free users on the Basic plan. Additional free allocations include 1,800 free minutes per month on Azure Pipelines with a free parallel job, 2 GiB free storage on Azure Artifacts, and free access for Visual Studio subscribers and Stakeholders with limited functionality.

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.

Azure DevOps: What does the Basic + Test Plans tier add to Azure DevOps?

The Basic + Test Plans tier adds test planning and execution capabilities, browser-based testing, and centralized reporting features. This tier costs $52 per user per month compared to $6 per user for the Basic plan.

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.

Azure DevOps: How is Azure Artifacts priced?

Azure Artifacts provides 2 GiB of free storage, then charges $2 per GiB for 2-10 GiB, $1 per GiB for 10-100 GiB, $0.50 per GiB for 100-1,000 GiB, and $0.25 per GiB for over 1,000 GiB.
