Community Project Spotlight: aws-cost-cli

By BIOS Founding Team

Community Project Spotlight: aws-cost-cli

aws-cost-cli is an open source command-line tool built by BIOS founder Olamide Kosile for analyzing AWS spending across services, regions, accounts, and tags, without needing to open the AWS Console.

It breaks down cost by service, region, linked account, or resource tag, supports side-by-side period comparisons, and can forecast monthly spend with confidence ranges based on historical usage.

Other features include anomaly detection for unusual spending spikes, local budget tracking with progress reporting, Slack notifications for cost reports, and a live watch mode for real-time monitoring, all output as clean terminal tables, JSON, or CSV.

It's available via PyPI, GitHub, or Docker (no Python required for the Docker route), is MIT licensed, and only needs read-only Cost Explorer IAM permissions to run.

It's a great example of the practical, cloud-focused tooling our community builds, and a genuinely useful contribution opportunity if you work with AWS.
