Welcome to Native Client

Download SDK

Native Client is a sandbox for running compiled C and C++ code in the browser efficiently and securely, independent of the user’s operating system. Portable Native Client extends that technology with architecture independence, letting developers compile their code once to run in any website and on any architecture.

In short, Native Client brings the performance and low-level control of native code to modern web browsers, without sacrificing the security and portability of the web. Watch the video below for an overview of Native Client, including its goals, how it works, and how Portable Native Client lets developers run native compiled code on the web.

Guiding principles of Native Client

  • Developer flexibility to program in any language.
  • Running close to the metal to allow access to performance gains.
  • Protecting users from malicious code and malware.
  • Write-once, run-anywhere code portability across all user architectures.
