## What it is
Wt is a C++ web toolkit for building highly interactive web applications using a widget-based GUI abstraction, without writing JavaScript. It bundles a widget/rendering library, an async HTTP/WebSockets server, multiple connectors (FastCGI, ISAPI), a C++ ORM (Wt::Dbo), and an authentication framework.

## Use cases
- build interactive web apps in C++ without JavaScript
- develop a web GUI with widgets and signal/slot events
- map C++ objects to PostgreSQL, MySQL, SQLite, SQL Server, or Firebird with an ORM
- add authentication and session security to a C++ web app
- generate dynamic PDF reports from a web application
- render 2D and 3D graphics (WebGL/canvas) in a C++ web app
- deploy a self-contained C++ web server with WebSockets support

## When to choose
- your team writes C++ and wants full-stack web development in one language
- you need a server-driven, widget-based alternative to JavaScript SPA frameworks
- you want built-in protection against XSS, CSRF, and SQL injection
- you need an integrated C++ ORM and auth framework alongside the UI layer
- you must support non-JavaScript or plain-HTML user agents and crawlers

## When to avoid
- you want a large ecosystem of JavaScript libraries, packages, and community resources
- your team primarily works in Python, Node.js, or another higher-level language
- you need fine-grained control over frontend markup and CSS for custom designs
- you are building a simple static site or REST API only
