Deep dives, release notes, and ideas from the CostGraph team on cloud cost optimization and infrastructure efficiency.

Migrating from OpenCost to CostGraph
CostGraph is now a drop-in replacement for OpenCost: keep the clients you built on the OpenCost API, cover the bills outside the cluster, and answer the same questions with the CostGraph CLI.

Bringing CostGraph to the CLI
CostGraph announces early access to the CostGraph CLI.

CostGraph launches support for Stripe
Our first export integrations send data out instead of in. CostGraph now reports each customer's attributed cloud spend to a Stripe billing meter every night, so infrastructure costs land on the invoice as line items.

CostGraph launches support for Autumn
CostGraph now exports tenant compute usage as billable meters to Autumn, so usage-based SaaS can bill on the same container, runtime, CPU, and memory data they use to monitor costs.
CostGraph launches virtual tags
Tag any resource CostGraph has indexed without touching your infrastructure. Write rules once, describe them in plain English with Graph AI, and see who tagged what.

CostGraph launches support for OpenRouter
CostGraph now imports OpenRouter activity data, so teams can analyze model spend by model, upstream provider, and endpoint alongside their cloud and infrastructure costs.

CostGraph launches support for Google Cloud costs
CostGraph now ingests Google Cloud billing data from the FOCUS and Detailed usage cost exports in BigQuery, reconciling allocated and unallocated costs against your invoice with keyless access via Workload Identity Federation.

CostGraph launches first-class support for AWS
CostGraph now ingests AWS cost and usage data from a FOCUS 1.2 Data Export, preserving Savings Plans and Reserved Instance attribution, and reconciling allocated and unallocated costs against your invoice.

CostGraph launches support for PlanetScale costs
CostGraph now imports PlanetScale invoice line items and database metadata, normalizing PlanetScale spend into the same cost model as your cloud and Kubernetes costs.
