Why We Built JaisCloud — A Free, Single-Binary AWS Emulator in Go

If you've ever tried to test AWS-dependent code locally, you've probably reached

for LocalStack. It works — but it comes with baggage: Python runtime, Docker

dependency, and the features most teams actually need locked behind a Pro subscription.

JaisCloud is our answer to that problem.

What is JaisCloud?

Website: https://jaiscloud.com

Docker: docker pull rjaisval/jaiscloud-aws:latest

JaisCloud is Apache-2.0 licensed — free forever, no Pro tier, no usage limits.

If you have hit walls with LocalStack Community or just want a Go-native cloud

emulator that runs anywhere as a single binary, give JaisCloud a try.

Feedback and contributions are very welcome.

Star the repo if JaisCloud looks useful — it helps others find it.
