What is it?

EC2Instances.info is a comparison site for Amazon EC2 instance types. It lets users view and compare instance metrics such as CPU, memory and network capacity alongside on-demand, reserved and spot pricing, instead of navigating AWS's own pages.

The repository contains the Next.js front end and a Go scraper that pulls instance data from the AWS, Azure and GCP APIs. The scraper also enriches each EC2 instance with its launch date from a public timeline, and the site is built as static files that can be deployed to a web server or Cloudflare.

The project is hosted by Vantage and maintained with community contributions. Developers can run it locally with Docker and Node, or build a full release with their own credentials and settings.

Key features

  • 01Compares EC2 instance specs and pricing side by side.
  • 02Scraper collects instance data from AWS, Azure and GCP APIs.
  • 03Static site output that can be deployed to any web server or Cloudflare.
  • 04Includes instance launch dates sourced from a public timeline.
  • 05Runs locally with Docker and Node.js for development.

Use cases

  • Choosing an EC2 instance type for a workload by comparing specs and cost.
  • Checking which regions offer a given instance type or spot price.
  • Self-hosting a custom instance comparison site with your own data.

Quick start

  1. 1

    Install Docker, then run npm ci in the repository root

    npm ci
  2. 2

    Fetch the latest CI build artifact (if not scraping data)

    curl -L https://instances.vantagestaging.sh/www_pre_build.tar.gz | tar -xzf -
  3. 3

    In the next directory, run nvm use, then npm ci, npm run init, and npm run dev

    npm run dev

Things to know

  • Scraping requires AWS, Azure and GCP credentials with specific permissions.
  • Full production builds take about 30 minutes and need many environment variables.
