Bottle Microframework

Bottle is a minimalist Python web framework that fits in a single file (~4000 lines). It provides URL routing, request/response handling, template rendering, and static file serving without external dependencies beyond the standard library. Bottle teaches HTTP fundamentals in clean, readable code. It's perfect for startups, IoT backends, and scripting-to-web transitions. Learning Bottle demystifies larger frameworks (Flask, Django) and makes you a better HTTP architect. It's quick to prototype ideas and deploy on minimal infrastructure.
