Dylibso, Inc. is the company behind Extism, the open-source, cross-language framework for building with WebAssembly (Wasm). Its focus is AI-driven application extensibility: giving developers an off-the-shelf, secure-by-default, fully sandboxed plug-in system that is "just a library import away" and runs almost anywhere, with idiomatic Host SDKs for JavaScript, Python, Rust, Ruby, Go, .NET, PHP, Java, C/C++, OCaml, Haskell, Perl, and Zig. Beyond Extism, Dylibso builds Chicory (a native pure-JVM WebAssembly runtime) and Turbo MCP (formerly mcp.run / XTP), a standards-compliant, self-hosted Model Context Protocol gateway and management platform with OIDC identity integration and audit controls. Dylibso is backed by Felicis.
