Floci ships local emulators for AWS, Azure, GCP, and OCI with 24ms cold start and no auth tokens
What happened
Floci 把 AWS、Azure、GCP 和 OCI 的云服务做成了能在本地跑的独立二进制文件，MIT 协议开源。AWS 模拟器直接占 4566 端口，兼容 LocalStack，覆盖 119 个服务，冷启动 24 毫秒，空闲只吃 13 MiB 内存。Azure 覆盖 28 个服务，GCP 25 个，OCI 8 个。项目明确冲着 LocalStack...

Floci open-sourced a set of local cloud emulators for AWS, Azure, GCP, and OCI under the MIT license. Each is a standalone binary: the AWS emulator is a drop-in LocalStack replacement on port 4566 with 119 services, 24ms cold start, and 13 MiB idle memory. Azure covers 28 services, GCP 25, and OCI 8. The project explicitly positions itself against LocalStack's March 2026 auth-token requirement, promising no sign-ups or keys ever. Lambda, RDS, and Redis run on real engines rather than mocks, so locally verified behavior should match production. A unified CLI and visual dashboard are included. The post does not disclose a specific version number or the benchmarking environment for the performance claims.
