Deno

Deno Land Inc. was formally established in 2021 by Ryan Dahl and Bert Belder to develop and commercialize the Deno JavaScript runtime. Deno is an open-source, secure-by-default runtime for JavaScript, TypeScript, and WebAssembly built on the V8 engine and Rust. It features built-in TypeScript support, a complete toolchain (linter, formatter, test runner, compiler), web-standard APIs, and native npm/Node.js compatibility. Commercial offerings include Deno Deploy (serverless hosting), Subhosting (secure infrastructure for multi-tenant platforms), and Deno Sandbox (Linux VM execution for untrusted code). The GitHub repository has over 100,000 stars and serves 400,000+ active users. The company has raised funding from Shasta Ventures, Mozilla Corporation, and others.
