Terragrunt provides several caching mechanisms to improve performance and reduce bandwidth usage when working with OpenTofu/Terraform. These features ensure that providers and content are downloaded and stored efficiently, avoiding redundant work across multiple units.

Terragrunt's caching ecosystem includes:

- **Provider caching** to avoid redundant downloads of large provider binaries
- **Content deduplication** to share identical content across multiple configurations
