pipx install devops-aws-costlens

Verify installation:

aws-costlens --version

---

📖 Quick Start

# Cost dashboard (default command)
aws-costlens --profiles <profile>

# Resource scan
aws-costlens scan --profiles <profile>

# 6-month cost history
aws-costlens history --profiles <profile>

---

⏱️ Time Range Options

CostLens supports flexible time range comparisons:

Option	Description	Example
(default)	Current month (MTD) vs last full month	aws-costlens --profiles mfa
last-month	Last full month vs prior full month	aws-costlens --profiles mfa --time-range last-month
N (days)	Last N days vs previous N days	aws-costlens --profiles mfa --time-range 30
YYYY-MM-DD:YYYY-MM-DD	Custom date range vs prior same-length window	aws-costlens --profiles mfa --time-range 2025-12-01:2026-01-01

Examples:

# Last 7 days vs previous 7 days (spike detection)
aws-costlens --profiles mfa --time-range 7

# Full December 2025 vs November 2025
aws-costlens --profiles mfa --time-range last-month

# Last 90 days vs previous 90 days
aws-costlens --profiles mfa --time-range 90

---

🏷️ Tag Filtering

Filter costs by AWS cost allocation tags:

# Single tag
aws-costlens --profiles mfa --tag Project=CDS

# Multiple tags (AND logic)
aws-costlens --profiles mfa --tag Project=CDS --tag Environment=prod

Note: Cost allocation tags must be activated in AWS Billing for tag-based filtering to work.
