It provides a decorator-based API for defining REST endpoints, scheduled tasks, and event handlers (S3, SNS, SQS) without boilerplate infrastructure code. The framework generates IAM policies automatically and handles deployment through a command-line tool that manages Lambda functions, API Gateway, and related resources.\n\nYou write Python functions decorated with @app.route(), @app.schedule(), or @app.on_s3_event() and run `chalice deploy` to push your application to AWS. Chalice abstracts away CloudFormation templates and manual resource provisioning, making it practical for developers who want to focus on application logic rather than AWS infrastructure plumbing. It supports Python 3.10 through 3.14 and depends on botocore and other standard AWS SDK libraries.","worth_installing":"Yes, if you are building serverless applications on AWS Lambda and want to avoid infrastructure boilerplate. Chalice is actively maintained, has no known vulnerabilities, low install friction, and a permissive license. It is well-suited for REST APIs, scheduled tasks, and event-driven Lambda handlers. Not suitable if you need multi-cloud deployment or prefer explicit infrastructure-as-code control."},"id":"chalice","links":{"html":"https://skillfed.io/packages/chalice","md":"https://skillfed.io/packages/chalice.md","pypi":"https://pypi.org/project/chalice/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-07","license_spdx":null,"license_treatment":"permissive","name":"chalice","python_support":"supports_current","summary":"Microframework"},"popularity":{"monthly_downloads":763727,"position":5125,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.33.0"}
