Holy shit... a team open sourced an AWS emulator that runs the entire cloud on your laptop with 13 MiB of memory. It's called Floci and it boots 45 AWS services in under a second, no Docker, no LocalStack subscription, no $30/mo dev environment bills. Every AWS dev tool before this needed Docker, gigabytes of RAM, and 30 second cold starts just to test a Lambda function. Floci is a single Go binary that runs the entire AWS stack in memory and starts faster than your terminal can render the prompt. Here's what makes it different from every AWS emulator that came before: → 13 MiB total memory footprint, the average Chrome tab uses 200x more RAM than this entire AWS clone → 45 services emulated locally including S3, Lambda, DynamoDB, SQS, SNS, IAM, CloudFormation, Step Functions, all in one binary → Sub-second cold start, your tests finish before LocalStack even pulls its Docker image → Zero dependencies, no Docker daemon, no Python runtime, no Java VM, just one Go executable → Drop-in compatible with AWS SDK and CLI, point your endpoint at localhost and every existing script works untouched Killed: $40/mo LocalStack Pro, every AWS dev environment burning $200+/mo on staging accounts, Docker Desktop eating 4GB of RAM just to run a fake S3 bucket. Pre-built binaries for Linux, macOS, Windows. No install scripts, no config files, no setup wizard. Download the binary, run it, your local AWS is live. Works in CI pipelines where spinning up Docker containers takes longer than the actual tests. 100% Opensource. Repo: github.com/floci-io/floci
