I maintain LocalEmu, a free and open-source (Apache 2.0) AWS emulator. It started as a fork of the archived LocalStack Community edition. The goal is to keep a genuinely free, open local AWS emulator alive and maintained.
What it does:
- Emulates 132 AWS services on a single endpoint (
localhost:4566) - Pure-Python core, with real Docker engines for Lambda, EC2, RDS, ECS, EKS, and OpenSearch
- Point your existing AWS CLI, boto3, Terraform, CDK, or Pulumi at it, zero config
- No account, no auth token, no telemetry. Persistent state across restarts
- Optional fidelity knobs: IAM policy enforcement, throttling, latency injection, Lambda cold starts
Why I built it: kill the multi-minute deploy loop, drop the dev/test AWS bill to zero, and stop keeping real credentials on dev machines.
It’s for fast local dev, testing, and learning, not production, and not bit-for-bit parity with the real cloud.

Happy to answer questions, and feedback is very welcome.
you’re aware you’re talking to a parrot?
I think it’s important that people see these conversations. Not everyone is aware of the impact of LLMs and if it changes the mind of at least a person, this is not a wasted effort.
I don’t feel like OP is a robot with how its response are written, but we never know.
