+# Use Cases
+
+WebAssembly's [high-level goals](HighLevelGoals.md) define *what* WebAssembly
+aims to achieve, and in *which order*. *How* WebAssembly achieves its goals is
+documented for [Web](Web.md) and [non-Web](NonWeb.md) platforms. The following
+is an unordered and incomplete list of applications/domains/computations that
+would benefit from WebAssembly and are being considered as use cases during the
+design of WebAssembly.
+
+## Inside the browser
+
+* Better execution for languages and toolkits that are currently cross-compiled
+  to the Web (C/C++, GWT, …).
+* Image / video editing.
+* Games:
+  - Casual games that need to start quickly.
+  - AAA games that have heavy assets.
+  - Game portals (mixed-party/origin content).
+* Peer-to-peer applications (games, collaborative editing, decentralized and
+  centralized).
+* Music applications (streaming, caching).
+* Image recognition.
+* Live video augmentation (e.g. putting hats on people's heads).
+* VR and augmented reality (very low latency).
+* CAD applications.
+* Scientific visualization and simulation.
+* Interactive educational software, and news articles.
+* Platform simulation / emulation (ARC, DOSBox, QEMU, MAME, …).
+* Language interpreters and virtual machines.
+* POSIX user-space environment, allowing porting of existing POSIX applications.
+* Developer tooling (editors, compilers, debuggers, …).
+* Remote desktop.
+* VPN.
+* Encryption.
+* Local web server.
+* Common NPAPI users, within the web's security model and APIs.
+* Fat client for enterprise applications (e.g. databases).
+
+# Outside the browser
+
+* Game distribution service (portable and secure).
+* Server-side compute of untrusted code.
+* Server-side application.
+* Hybrid native apps on mobile devices.
+
+# How WebAssembly can be used
+
+* Entire code base in Web Assembly.
+* Main frame in Web Assembly, but the UI is in JavaScript / HTML.
+* Re-use existing code by targeting Web Assembly, embedded in a larger
+  JavaScript / HTML application. This could be anything from simple helper
+  libraries, to compute-oriented task offload.
