The short version

  • Each has a real cost: 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.; Metasploit the free Framework edition is command line only; the web interface is Pro only
  • They diverge on capability: Atlantis covers Pull request plans, Metasploit covers Exploit database.
  • Prices and features above were last checked on 31 August 2026.

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.

Metasploit

  • The free Framework edition is command line only; the web interface is Pro only
  • Automated exploitation, automated credential attacks and antivirus evading dynamic payloads are restricted to Metasploit Pro
  • Reporting, audit wizards, task chains and closed loop vulnerability validation are Pro only
  • Rapid7 publishes no price for Metasploit Pro and routes buyers to contact sales

What is Atlantis best used for?
Atlantis is most often used for making terraform review meaningful by putting the actual plan output in front of the approver, removing local applies and the credential sprawl that comes with every engineer holding production keys, getting pull request driven infrastructure without paying a per-user subscription for a hosted platform, enforcing conftest policies as a blocking check before an apply can run.

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.

Metasploit: Is Metasploit Framework free to use?

Yes, Metasploit Framework is available as free open-source software with source code accessible via GitHub. Community support is provided through Slack, GitHub, Twitter, and email.

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.

Metasploit: What is the difference between Metasploit Framework and Metasploit Pro?

Metasploit Framework is the free open-source version. Metasploit Pro is a commercial offering with customer support from Rapid7, though specific pricing and features are not detailed on the download page.

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.

Metasploit: What support is available for the free Framework version?

Community-based support for Metasploit Framework is available through Slack, GitHub, Twitter, and email ([email protected]). Commercial customers using Metasploit Pro receive customer support from Rapid7.

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.
