Shopify's WebAssembly-based extension platform — run merchant-defined logic at the edge for checkout, discounts, and shipping.
Shopify Functions is Shopify's production WebAssembly platform for theme and checkout extensions. Merchants and partners author extension logic in Rust or AssemblyScript, compile it to Wasm, and Shopify executes it at the edge as part of checkout, cart validation, and shop customization. Functions replaced the legacy ScriptTag and App Proxy extension models and now handles billions of extension invocations per week, making it one of the largest production Wasm deployments in the world.
A serverless platform running on V8 isolates across 300+ global edge locations with native WebAssembly module support.
