What it is and what it does
Bottle is a single-file WSGI microframework designed for small web applications. It bundles routing, templating, and HTTP utilities into one module with zero external dependencies, making it quick to install and deploy. The framework handles URL mapping to functions, provides a built-in template engine, and can integrate with external template engines. It includes a development server and works with standard WSGI servers for production use.
The framework is aimed at developers who want a minimal, self-contained tool for web development without overhead. Its single-file distribution and lack of dependencies make it portable and suitable for embedded use or rapid prototyping. It supports Python 2.7 and Python 3.8 through 3.13, though the project is classified as Beta status.
Use it for
- Build a small REST API or web service that needs routing and HTTP utilities without framework overhead.
- Prototype a web application quickly using the built-in development server and template engine.
- Embed a lightweight HTTP interface into an existing Python application or tool.
- Create a simple web application that runs on constrained environments where minimal dependencies matter.
- Serve templated HTML responses with form data handling and cookie management.
