Atlantis

Open-source Terraform pull request automation tool

Code & DevelopmentFree

Atlantis is an open-source tool that automates Terraform plan and apply workflows via pull request comments. When a developer opens a PR with Terraform changes, Atlantis automatically runs terraform plan and posts the output as a PR comment. Reviewers can see exactly what infrastructure will change before approving, and after merge, Atlantis runs terraform apply automatically. Atlantis is the foundational tool for GitOps-style Terraform workflows and is deployed by thousands of engineering teams.
