AI visibility report for Wasmer in Open Source Commercial / OSS Infrastructure.

Wasmer is an open-source WebAssembly (Wasm) runtime company founded in 2018 and headquartered in San Francisco, backed by Y Combinator. Written in Rust, the Wasmer runtime enables fast, secure, sandboxed execution of WebAssembly modules across servers, browsers, mobile devices, IoT, and edge environments. It supports multiple compiler backends (Cranelift, LLVM, Singlepass) and introduces WASIX, a POSIX extension layer allowing legacy applications to run in Wasm without code rewrites. The company's commercial platform comprises three products: the Runtime (embeddable across Rust, Python, JavaScript, Go, Ruby, and C), the Registry (a WebAssembly package manager), and Wasmer Edge (a serverless edge cloud with sub-millisecond cold starts). Wasmer has over 20,000 GitHub stars and more than 20,000 community users.

Wasmer provides a three-product WebAssembly platform: (1) the Wasmer Runtime—an open-source, Rust-written Wasm execution engine supporting Cranelift, LLVM, and Singlepass compiler backends with WASI, WCGI, and Emscripten runners and SDKs for six languages; (2) the Wasmer Registry—a WebAssembly package manager enabling publishing, sharing, and running Wasm packages via CLI; and (3) Wasmer Edge—a serverless edge cloud with global CDN, sub-millisecond cold starts, automatic scaling, and support for HTTP, TCP, and UDP workloads. The runtime's WASIX extension provides POSIX compatibility, enabling unmodified legacy applications (PHP, Python, PostgreSQL, Bash) to run sandboxed in WebAssembly.
