## What it is
Microdot is a minimalistic async web framework for Python and MicroPython, inspired by Flask, designed to run on resource-constrained systems like microcontrollers. It supports routing, WebSockets, SSE, authentication, and form handling in a tiny footprint.

## Use cases
- build a rest api on an esp32 with micropython
- serve a small web app from a microcontroller
- run a lightweight http server with async handlers
- host a websocket endpoint on embedded hardware
- create a flask-like web app without heavy dependencies

## When to choose
- you need a web server on a microcontroller or memory-limited device
- you want a Flask-like API in a tiny dependency-free package
- you need async request handling in CPython or MicroPython

## When to avoid
- you need a full-featured framework with built-in ORM, admin, or large ecosystem
- you are building a high-traffic production web service
- you rely on extensive third-party Flask extensions

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, http-server, routing, websocket, templating
- domain: web-development, backend, iot, embedded-systems
- platform: python, cross-platform, embedded, iot
- tags: micropython, flask-inspired, async, microcontrollers, minimalist
