## What it is
EC2Instances.info is an open-source web application for comparing Amazon EC2, RDS, and ElastiCache instance types, specs, and pricing across regions and purchase terms. It is maintained and hosted by Vantage, with data scraped from AWS, Azure, and GCP APIs via a Go scraper and rendered through a Next.js frontend.

## Use cases
- compare EC2 instance pricing across AWS regions
- find the cheapest instance type with 4 vCPUs and SSD storage
- estimate monthly cost of an RDS instance with reserved pricing
- filter cloud instances by GPU, memory, or network performance
- share a comparison of selected instance types with my team
- look up which instance families support NVMe storage

## When to choose
- you need a fast, filterable view of EC2/RDS/ElastiCache specs and prices without digging through AWS console pages
- you want regex/glob filtering and side-by-side instance comparison with shareable URLs
- you want to self-host or contribute to an open-source cloud cost comparison tool

## When to avoid
- you need full multi-cloud cost management, budgets, or billing analysis rather than instance comparison
- you need real-time pricing from your own AWS account or savings plan recommendations
- you need a programmatic pricing API rather than an interactive website
