Bottle is a lightweight WSGI micro web-framework for Python that enables rapid development of web applications with minimal overhead.
Bottle addresses the need for a simple, dependency-free web framework by providing core functionality through a single-file module that relies only on the Python Standard Library. It handles HTTP request routing to functions, includes a built-in template engine with support for external engines like Mako, Jinja2, and Cheetah, and offers utilities for managing form data, file uploads, cookies, and headers. The framework includes a development server and adapters for production WSGI servers such as Gunicorn, Paste, and Cheroot.
Bottle suits developers building small to medium-sized web applications or REST APIs who value simplicity and want to avoid dependency management complexity. Its single-file distribution makes it easy to embed in projects or deploy without package installation. The framework is appropriate for prototyping, learning web development, or situations where a minimal footprint is essential. Developers should choose Bottle when they prioritize straightforward routing and templating over the extensive ecosystem and built-in features of larger frameworks.
The project maintains active test coverage through automated testing workflows. Development activity shows consistent engagement with the codebase through regular updates and maintenance of the repository.
