The short version

  • Each has a real cost: Aikido free plan includes fair-usage limits on repos and container images; 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.
  • They diverge on capability: Aikido covers Static Application Security Testing (SAST), Atlantis covers Pull request plans.
  • 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.

Aikido

  • Free plan includes fair-usage limits on repos and container images
  • Pricing increases significantly with user and repository scale
  • Advanced features like penetration testing and VM scanning limited to higher tiers
  • Device protection limited to Development environments only
  • Requires multiple plan tiers for full platform coverage

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.

Answered from the vendors’ own pages

Aikido: What is included in Aikido's free Developer plan?

The free Developer plan includes up to 2 users with SAST, SCA, secrets detection, cloud scanning, and license risk detection. Fair-usage limits apply: 10 repos, 2 container images, 1 domain, and 1 cloud account.

Source
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.

Aikido: What is AutoFix and how does it work?

AutoFix is Aikido's automated vulnerability remediation feature that identifies vulnerabilities and suggests or applies specific code fixes automatically, reducing manual remediation effort.

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.

Aikido: How many false positives does Aikido reduce?

Aikido reduces false positives by 99%, using AI-powered context awareness to filter noise and focus on vulnerabilities that present real business risk.

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.

Aikido: What integrations does Aikido support?

Aikido integrates with Jira, Linear, Slack, Teams, GitHub, GitLab, and other popular development tools to fit into existing workflows.

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.
