OpenMeter
Metering and Billing for AI, API and DevOps
OpenMeter is an open-source metering and billing platform designed to collect, aggregate, and analyze usage events from APIs, cloud infrastructure, and software services in real time, enabling flexible usage-based billing for SaaS, AI, and DevOps offerings. It supports high-scale event ingestion and deduplication to accurately record how customers consume billable resources such as API calls, compute time, or storage, and then correlates that usage with payment systems and billing plans to automate invoicing and revenue recognition. The system includes metering, storage, cataloging of products and pricing rules, and tools to enforce limits or quotas, supporting both self-service customer portals and internal dashboards. OpenMeter integrates with payment processors, CRMs, and analytics systems, letting teams launch complex pricing models or subscription tiers without heavy custom engineering work. -

Finala
Finala is an open-source resource cloud scanner
Finala is an open-source cloud resource scanner that detects and reports on unused or wasteful cloud assets, helping organizations reduce unnecessary expenses and optimize their infrastructure footprint by continuously analyzing deployed resources against user-defined rules. It scans cloud environments, identifies idle or underutilized machines, unattached storage, or resources not aligned with utilization policies, and presents actionable insights that help teams reclaim budget and compliance. Users define scanning criteria and thresholds in configuration files to tailor detection to their operational needs, making Finala flexible across different organizational scales and cloud setups. The tool then outputs reports and notifications about inefficient resources, enabling cost-conscious engineering teams to make informed decisions about shutting down or rightsizing assets. Because it’s self-hosted and rule-based, Finala can be integrated into CI/CD and monitoring workflows. -

Infracost
Cloud cost estimates for Terraform in pull requests
Infracost scans for Terraform code changes and checks over 3 million prices to create a simple, understandable cost estimate before any resources are launched. Infracost integrates into CI/CD so everyone knows the cost impact of changes without leaving the workflow. Infracost integrates with Open Policy Agent, Sentinel, and Conftest, enabling DevOps teams to set best practices as policies. Infracost automatically creates detailed, shareable cost estimates which can be sent to clients and managers with different scenarios. Infracost supports over 230 Terraform resources across AWS, Azure and Google. Other IaC tools, such as Pulumi, AWS CloudFormation/CDK and Azure ARM/Bicep are on our roadmap. Infracost can also estimate usage-based resources such as AWS S3 or Lambda! Infracost has many CI/CD integrations so you can easily post cost estimates in pull requests. This provides your team with a safety net as people can discuss costs as part of the workflow. -

Infracost VSCode Extension
See cost estimates for Terraform right in your editor
Infracost's VSCode extension shows you cost estimates for Terraform right in your editor! Prevent costly infrastructure changes before they get into production. Compare configs, instance types, regions etc: copy/paste a code block, make changes and compare them. Quick cost estimate: write a code block and get a cost estimate without having to use AWS, Azure or Google cost calculators, or read the long/complicated pricing web pages. Catch costly typos: if you accidentally type 22 instead of 2 as the instance count, or 1000GB volume size instead of 100, the cost estimate will immediately pick that up and let you know. See cost estimates right above their Terraform definitions. Infracost's output updates on file save. Both resource and module blocks are supported. 3rd party module blocks are also supported! -

Azure Cost CLI
CLI tool to perform cost analysis on your Azure subscription
azure-cost-cli is a command-line tool that simplifies cost analysis for Microsoft Azure subscriptions by retrieving, summarizing, and visualizing spending data directly from the CLI, helping cloud operators and finance teams understand where resources are generating costs. Users can run the tool against their Azure account to output cost breakdowns by service, resource group, tag, or timeframe, enabling quick identification of costly services or budget overruns without needing to navigate the Azure portal. It supports filtering and aggregation so teams can tie spend to organizational units or project initiatives, and it’s particularly useful for scripting automated cost checks in CI/CD pipelines or periodic reports. By bringing cost insights to the terminal, the tool helps engineers and managers catch inefficiencies early and make data-driven decisions about scaling, shutting down unused services, or optimizing reserved instances. -

Selefra
The open-source policy-as-code software that provides analysis
Selefra is an open-source policy-as-code and infrastructure analysis tool that helps engineering and security teams gain visibility into complex multi-cloud and SaaS environments by treating infrastructure data as queryable information. The core idea behind Selefra is “select * from infrastructure,” meaning you can write flexible SQL-style queries against cloud configuration and inventory data assembled from dozens of services such as AWS, Azure, GCP, Kubernetes, GitHub, Slack, and more, bringing auditing, security, compliance, cost optimization, and architecture insights into one place. It unifies data across provider APIs into a structured model, making it simple to detect misconfigurations, enforce governance policies, and build custom analytics workflows that align with organizational standards. Users can manage policies as code, version them alongside application code, and automate analysis and enforcement through scheduled tasks, CI/CD, or policy-as-code tooling. -

Cloud Cost Handbook
Set of guides meant to help explain often-times complex pricing
The Cloud Cost Handbook by vantage-sh is an open-source, community-driven documentation project that breaks down the often confusing and opaque pricing models of major public cloud providers into clear, practical guides written in plain English. It’s intended as an educational resource for developers, finance teams, and FinOps practitioners who need to understand how cloud costs are structured, what drives pricing across services, and how to estimate, optimize, and forecast spend without wading through dense official documentation. The handbook covers core concepts, pricing examples, cost-optimization techniques, and billing models across providers such as AWS, Azure, and GCP, with each section curated to improve clarity and accessibility for readers without deep financial or cloud billing expertise. Because it’s hosted on GitHub and open to contributions, anyone from beginners to experts can add insights, examples, and updated pricing patterns as cloud offerings evolve. -
