terraform-lockfile-insights is a utility designed to surface information about the Terraform providers used within a project. It recursively crawls a specified directory, parsing each Terraform lockfile using tree-sitter, and provides a report showing which providers and versions are used in each file. Building this tool helped me get hands-on experience with both Golang and tree-sitter. I often work with repositories containing numerous Terraform modules, where managing provider versions and keeping the dependency scope small is crucial.
