Floci is a local emulator for AWS services and cloud infrastructure designed for developing and testing applications without a live internet connection. It serves as a containerized cloud emulator and a serverless runtime emulator, allowing users to run high-fidelity replicas of cloud databases, queues, and compute services on a local machine. The project distinguishes itself by using real container images instead of simple mocks to ensure behavioral accuracy. It functions as a local API gateway simulator with proxy-based routing for REST and WebSocket APIs, and provides a serverless environm
serverless-offline is a Serverless Framework plugin that provides a local cloud infrastructure simulator. It acts as an AWS Lambda local emulator and AWS API Gateway mock, allowing for the development and testing of serverless functions on a local machine without deploying to a remote provider. The project distinguishes itself by simulating bidirectional WebSocket connections and message routing, as well as mimicking the request lifecycle of an HTTP gateway. It includes a mock identity authorizer pipeline to verify tokens and JWTs locally and supports the mounting of virtual dependency layers
The AWS Lambda Runtime Interface Emulator is a proxy server designed to replicate the cloud-based serverless execution environment within a local container. It functions as a lightweight interface that allows developers to verify function logic, performance, and API integration by simulating the remote control plane and event invocation model on a local machine. The tool operates by intercepting HTTP requests and translating them into the structured JSON event payloads expected by serverless function handlers. It manages the function lifecycle through a synchronous event loop and maps local c
docker-lambda is a Docker-based serverless simulator and local emulator designed to replicate AWS Lambda runtime environments. It provides a system for executing serverless functions locally and mirroring cloud execution environments through containerized images. The project includes a local API server that allows for function invocation via HTTP to eliminate cold starts during testing. It features a build tool for compiling native dependencies and packaging function code into deployment archives using specialized system images. The environment supports mirroring shared dependency layers by
