How Compiler Explorer Runs on AWS
SMRTR summary
Compiler Explorer (godbolt.org) runs on AWS using CloudFront, spot EC2 instances, EFS with a custom SquashFS-based caching system called CEFS, and a growing fleet of nightly compiler builds. The site serves ~78 million compilations per year at roughly $0.0007 each, hosts 6,000+ compiler versions across 93 languages, and costs around $3,600/month — largely covered by AWS open source credits.
