## What it is
Blade is a lightweight, high-performance MVC web framework for Java 8 built on Netty 4, with RESTful routing, a built-in template engine, and middleware support in a sub-500kb footprint. It aims to be a simple, elegant alternative to heavier Java web stacks like Spring, runnable as a single JAR.

## Use cases
- build a lightweight REST API in Java without Spring
- create a small MVC web application with a single JAR
- serve web pages with a simple Java template engine
- add CSRF and XSS protection to a Java web service
- run scheduled cron tasks inside a Java web app
- learn a minimal Java web framework quickly

## When to choose
- you want a fast, minimal Java web framework without Spring's complexity
- you need an embedded Netty-based server with RESTful routing
- you prefer annotation-driven, low-configuration Java web development

## When to avoid
- you need a large ecosystem of enterprise integrations and community support
- your team standardizes on Spring Boot or Jakarta EE
- you require long-term guaranteed maintenance, as activity is limited

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-framework, routing, middleware, templating, http-server
- domain: web-development, backend, apis
- platform: jvm, cross-platform
- tags: mvc, restful, netty, lightweight, java8, embedded-server
