HTTP/3 and WebTransport for Node.js, built on MSH3 and MsQuic.
The project is preparing its first public release. Its release monorepo contains the JavaScript API, portable development-certificate utilities, platform packages, native loader, protocol tests, and reproducible release tooling:
http3-server— thehttp3sserver and@http3-server/*npm packages.
The native runtime is built for macOS, Linux, and Windows on arm64 and x64. Every published binary is tied to one checksummed producer revision and exercised across the supported Node.js release lines before promotion.
The HTTP/3 request API is usable today; the WebTransport API remains experimental while
its stream support and browser interoperability matrix expand. See the
http3-server README for the
current support boundary and local Vite example.
Please report suspected vulnerabilities privately through the
http3-server security policy.
