Nacl-web-plug-in
This version required developers to compile separate binaries for each specific CPU architecture (e.g., x86, ARM). While highly performant, it lacked the "write once, run anywhere" portability typical of the web.
Google completely removed support for PNaCl from the Chrome browser for the general public, effectively rendering legacy NaCl web applications obsolete.
WebAssembly took the core concepts of PNaCl—compiling C/C++ to an intermediate bytecode executed safely in the browser—but designed it from scratch as an open, standard web technology built directly into the browser's JavaScript engine. The Legacy of NaCl

In 2017, Google officially announced the deprecation of NaCl in favor of WebAssembly, eventually removing support for it in Chrome for most users. The Legacy of NaCl
Several specific issues have been reported by users:
Google Chrome was the only major browser to fully implement and support NaCl. Competitors like Mozilla (Firefox), Apple (Safari), and Microsoft (Internet Explorer/Edge) resisted adopting it, viewing it as a proprietary, Chrome-centric technology that fragmented the open web standard. In 2017, Google officially announced the deprecation of
Native Client (NaCl) is a sandboxing technology that allows you to run compiled C and C++ code in web browsers, leveraging the browser's multi-process architecture to provide enhanced security. A NaCl web plugin enables web developers to integrate native code modules into web applications, potentially offering performance boosts and access to hardware that standard web technologies might not provide.

The NaCl web plug-in was a browser extension and architecture that enabled the execution of native compiled code (like C, C++, and Go) directly within the browser ecosystem.
During its peak, the NaCl web plug-in enabled web experiences that were previously thought impossible without installing standalone desktop software:
