Region and Usage Configuration

Region Handling

By default, OpenInfraQuote shows pricing across all regions. If you know which region to use, pass it explicitly with the --region flag. This is optional.

Plan and state files do not contain region information, so it must be provided manually if you want region-specific estimates.

Usage-Based Estimates

Some cloud resources are priced based on usage, such as storage size or number of requests. OpenInfraQuote includes default estimates for common usage patterns to help provide directional cost data. You can customize these assumptions by providing your own usage.json file.

See an example usage file here.

Running with Docker

To run OpenInfraQuote with Docker:

docker run --rm -i \
  -v $(pwd)/prices.csv:/prices.csv \
  -v $(pwd)/tfplan.json:/tfplan.json \
  ghcr.io/terrateamio/openinfraquote:latest \
  match --pricesheet /prices.csv /tfplan.json \
  | docker run --rm -i \

FAQ

Is OpenInfraQuote 100% open-source?

Yes. There are no proprietary components or hidden features.

Which cloud providers are supported?

Currently AWS. GCP and Azure support is coming soon.

How accurate are the estimates?

Estimates are based on pricing data from official cloud provider APIs. OpenInfraQuote uses a pricing sheet (prices.csv) that is updated daily to reflect the latest public pricing. This file is downloaded and used locally, so your estimates stay current without needing a backend service.

Final costs depend on actual usage and any applicable discounts.
