  "textContent": "submitted by nullroute to programming\n74 points | 14 comments\nhttps://localemu.cloud/\n\nI 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.\n\nWhat it does:\n\n  * Emulates **132 AWS services** on a single endpoint (`localhost:4566`)\n  * Pure-Python core, with **real Docker engines** for Lambda, EC2, RDS, ECS, EKS, and OpenSearch\n  * Point your existing **AWS CLI, boto3, Terraform, CDK, or Pulumi** at it, zero config\n  * **No account, no auth token, no telemetry.** Persistent state across restarts\n  * Optional fidelity knobs: IAM policy enforcement, throttling, latency injection, Lambda cold starts\n\n\n\nWhy 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.\n\nIt’s for fast local dev, testing, and learning, not production, and not bit-for-bit parity with the real cloud.\n\nRepo: github.com/localemu/localemu Site: localemu.cloud\n\nHappy to answer questions, and feedback is very welcome.",
