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

LiquidPlanner

  • Rebranded to Tempo Portfolio Manager; the pricing page shows no published figures, only an early access sign-up

Answered from the vendors’ own pages

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.

Pricing is per-user per month and scales based on organization size. For 1-10 users: $1.00/user; 11-100 users: $5.21/user; 101-250 users: $3.66/user; scaling down to $0.25-$0.39/user for organizations with 5,000+ users.

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.

LiquidPlanner: What license matching requirement exists for Tempo?

Your Tempo license size must match your Jira license size, with a user defined as anyone who can log into Jira.

Atlantis: Does it work with OpenTofu?

LiquidPlanner: Is there a free trial for Tempo timesheets?

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.

LiquidPlanner: What deployment options are available for Tempo?

Both Cloud and Data Center deployment options are offered, with annual billing available.
