The short version

  • Only Atlantis has a free tier, so it costs nothing to try first.
  • 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.; GitHub Copilot agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • They diverge on capability: Atlantis covers Pull request plans, GitHub Copilot covers Code completion.
  • 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.

GitHub Copilot

  • Agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • Suggestions for niche or specialized programming languages are less accurate due to limited training data
  • Less effective with non-English prompts or grammatically incorrect developer instructions
  • Free tier severely limited to 2,000 completions and 50 chat requests per month

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.

GitHub Copilot: Does GitHub Copilot have a free tier?

Yes. GitHub Copilot Free offers 2,000 code completions and 50 chat requests per month at no cost with no credit card required. Students and open-source maintainers get free Pro access.

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.

GitHub Copilot: What IDEs and editors are supported?

GitHub Copilot works in VS Code, Visual Studio, JetBrains IDEs (IntelliJ, PyCharm, WebStorm), Vim, Neovim, and Azure Data Studio with extensions providing code suggestions and chat capabilities.

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.

GitHub Copilot: What programming languages does Copilot support?

Copilot supports more than 10 core languages including JavaScript, TypeScript, Python, Java, C#, Go, and Rust. Performance is strongest for these popular languages with extensive open-source training data.

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.

GitHub Copilot: How does the free tier compare to paid plans?

Free tier limits completions and chat to 2,000 and 50 per month. Pro ($10/month) offers unlimited completions, while Pro+ ($39/month) adds access to frontier AI models and agent mode for autonomous multi-file edits.
