A growing set of runtime features makes Extism an excellent plug-in system for apps of all types & sizes. Fully-featured canonical reference demo with Elixir host SDK, and plugins in Rust, TypeScript, & Javascript. Implementation of a turn-based multiplayer game platform and games included to play and review. Games are implemented as WebAssembly modules containing a specific set of exports. Check out the source code on GitHub, download the installer, and get started. 100% open-source code. Fork it, experiment, & run your own game server.
             | About
            Modsurfer provides ops & dev teams with the first system-of-record and diagnostics application to search, browse, validate, audit, and investigate WebAssembly binaries. At-a-glance insights into WebAssembly module data (code size & complexity, imports/exports & more). Search for details about modules (hash, ID, function names, strings, namespaces, errors & more). Easily audit and track all the WebAssembly code in your stack. Debug & triage issues otherwise difficult to pinpoint in opaque WebAssembly format. Write or generate a "check file" to track binary requirements. If a module fails validation, a helpful report is created to get things back on track. Validate your modules for import/export existence, function signature, security compliance, runtime complexity, & more. The CLI puts all your Modsurfer data at your fingertips and is the easiest way to interact with the Modsurfer desktop or enterprise server.
