(Native Client Web Plugin) represents one of the most ambitious, tech-forward, and ultimately transitional chapters in the history of web browser architecture. Developed primarily by Google as part of the open-source Chromium project, Native Client (NaCl) and its evolution, Portable Native Client (PNaCl), aimed to solve a fundamental dilemma of the early-to-mid 2010s: how to execute native C and C++ code inside a web browser at near-native speeds without compromising user security.

"Native Client is a sandbox for running untrusted x86 native code. It aims to give browser-based applications the computational performance of native applications without compromising safety. Native Client uses static binary analysis to detect security defects in untrusted x86 code, and dynamic fault isolation to limit the effects of bugs in untrusted code. We describe the design and implementation of Native Client, and evaluate its performance on compute-intensive benchmarks. We find that Native Client imposes a low performance penalty—typically less than 5%—while providing strong security guarantees."

Once Wasm landed, NaCl became redundant. Google officially and removed naclwebplugin entirely from Chrome in June 2019 (Chrome 76). naclwebplugin

The naclwebplugin enabled unique browser capabilities that were impossible with early 2010s JavaScript:
