## What it is
Owl is a lightweight (~30kb gzipped, zero dependencies) TypeScript UI framework built by Odoo, featuring signal-based reactivity, class-based components, XML templates, and async rendering. It powers Odoo's web client and works directly in the browser without a build toolchain.

## Use cases
- build a reactive single-page web app without a build step
- develop the frontend for an Odoo module or web client
- create a todo app with signal-based state management
- prototype a UI quickly using native ES modules in the browser
- share state and services across components with a type-safe plugin system
- render components asynchronously for smooth concurrent UI updates

## When to choose
- you want a small, zero-dependency frontend framework with no build tooling
- you prefer class-based OOP components over function components
- you are developing for or extending the Odoo web client
- you want explicit, debuggable signal-based reactivity
- you need dynamically modifiable XML templates

## When to avoid
- you need a large ecosystem of third-party components and libraries
- your team prefers hooks/function-based component models like React
- you require extensive tooling, devtools, and community support
- you are building SEO-heavy content sites better served by SSR frameworks
- you want a framework with a stable, long-term API guarantee (Owl 3 is alpha)
