Pluralith

Pluralith is a Terraform visualization tool that runs terraform plan under the hood to generate infrastructure diagrams automatically. It is designed to replace manual diagramming by producing visual documentation directly from a codebase, helping teams surface infrastructure changes, drift, and cost context before they are applied.

The platform integrates into CI pipelines, where the Pluralith CLI runs on every pull request and posts the generated diagram as a pull request comment. A dashboard provides a visual history of Terraform plans. Core capabilities include change highlighting, drift detection, and cost data via Infracost. Compliance data via Regula is listed as coming soon. The tool also offers an open-source CLI for local development, with instant local diagrams, change highlighting, drift detection, and cost information.

Pluralith is packaged as flat-rate plans with usage-based overflow pricing, based on the number of Terraform plan runs per month. The listed plan includes diagrams as PR comments, Terraform change history, cost integration, IAM, unlimited users, unlimited projects, unlimited exports, and local development. A free forever option is available for local use.
