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.
Octopus Deploy
- Free tier caps at 10 projects, 10 tenants, 10 machines, 10 users, 5 concurrent tasks and 1 space
- Annual billing is the only option for both Octopus Cloud and Octopus Server; there is no monthly plan
- Professional cloud tier is $4,330 per year and Enterprise cloud is $24,600 per year, with tenants and machines sold as add-ons beyond the free allotment

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.
Octopus Deploy: How much does Octopus Deploy cost?
Octopus Deploy offers a free tier at $0/year with limits on projects (10), users (10), and tenants (10). Professional plans start at $2,080/year for self-hosted or $4,330/year for cloud hosting.
SourceAtlantis: 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.
Octopus Deploy: What does the free Octopus Deploy tier include?
The free tier includes 10 projects, 10 tenants, 10 machines, 10 users, 5 concurrent tasks, 1TB file storage, 100GB database storage, and community support only.
SourceAtlantis: 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.
Octopus Deploy: Can I try Octopus Deploy for free before purchasing?
Yes, a free tier is available with unlimited duration but capped usage, plus a 30-day free trial with full Enterprise features is offered to evaluate the platform.
SourceAtlantis: 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.
Octopus Deploy: What are the Enterprise pricing differences between Cloud and Server hosting?
Enterprise Cloud hosting costs $24,600/year and includes 20 concurrent tasks and 24/7 support. Enterprise Server self-hosted costs $15,600/year with flexible concurrent task configuration and 24/7 support.
