Chalice is a framework for building and deploying serverless applications and REST APIs on AWS Lambda using Python. It functions as an infrastructure-as-code generator, mapping application logic and routing definitions directly to cloud compute resources while automating the provisioning and management of the underlying environment. The framework distinguishes itself by analyzing source code to automatically construct the minimum necessary security permissions, ensuring least-privilege access for all deployed functions. It supports modular development through blueprint-based organization and

OpenWhisk is a serverless cloud platform designed for deploying and executing stateless functions in response to API calls or events. It serves as a complete serverless stack, providing an API gateway for functions, a function-as-a-service runtime manager, and an event-driven workflow engine. The platform distinguishes itself through a polyglot execution model that supports multiple language runtimes and allows for the creation of custom runtimes using Docker containers. It enables complex logic through function orchestration and composition, allowing multiple functions to be chained into seq

Up is a deployment tool that transforms any HTTP server into an AWS Lambda function behind API Gateway with a single command, eliminating server management entirely. It provides a unified platform for building and deploying serverless APIs that scale automatically and charge only for actual usage, while supporting Node.js, Go, Python, Java, Crystal, and Clojure runtimes without per-language configuration. The tool automates the generation and management of all required AWS resources—including Lambda, API Gateway, CloudFront, and S3—from a declarative configuration, and can replicate the entir

Zappa is a deployment tool and orchestrator designed to package and deploy Python web applications to AWS Lambda. It functions as a wrapper and framework that adapts standard Python applications to work with serverless infrastructure and API Gateway events. The project enables the hosting of Python web frameworks on serverless environments without requiring the application to be rewritten. It automates the process of pushing code from local environments to the cloud and manages the lifecycle of these deployments to remove manual server management. Its capabilities include automated infrastru
