## What it is
Lift is an open-source, security-focused web framework for building interactive, scalable web applications in Scala on the JVM. It offers view-first templating, strong built-in protection against OWASP vulnerabilities, and industry-leading Comet and Ajax support, while deploying unchanged to standard Java servlet containers.

## Use cases
- build a secure web application in scala
- real-time interactive web framework for the jvm
- scala framework with built-in ajax and comet support
- deploy a scala web app to a servlet container like jetty
- view-first templating web framework
- web framework resistant to owasp top 10 vulnerabilities
- high-traffic scalable web application in scala

## When to choose
- your team works in Scala or wants to reuse existing Java libraries and JVM infrastructure
- you need strong security defaults and resistance to common web vulnerabilities out of the box
- you are building highly interactive, real-time pages where Comet-style server push matters
- you want to deploy on existing servlet containers and application servers (Jetty, Tomcat, NetWeaver)

## When to avoid
- you are not working on the JVM and have no Scala experience in the team
- you need a mainstream ecosystem with abundant hiring pool, tutorials, and community compared to Play or Spring
- your project is a lightweight REST/JSON microservice where a full view-first web framework is overkill
- your product is a heavily front-end SPA consuming a separate API, where Lift's server-driven model adds little
