Extism vs. Modsurfer vs. Python vs. WebAssembly Comparison Chart

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.

WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications. The Wasm stack machine is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to execute at native speed by taking advantage of common hardware capabilities available on a wide range of platforms. WebAssembly describes a memory-safe, sandboxed execution environment that may even be implemented inside existing JavaScript virtual machines. When embedded in the web, WebAssembly will enforce the same-origin and permissions security policies of the browser. WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand. The textual format will be used when viewing the source of Wasm modules on the web.
