Companies used it to run legacy desktop database applications and heavy engineering software inside a standardized web browser environment.

Running compiled machine code inside a browser sounds like a massive security risk. To prevent malicious code from hijacking a user's operating system, the NaClWebPlugin relied on a strict dual-sandbox mechanism:

Allowed developers to compile code once into an architecture-independent format that the browser would translate locally.

NaCl was heavily tied to Google Chrome and Chromium-based browsers. Other major browser vendors—most notably Mozilla (Firefox), Apple (Safari), and Microsoft (Edge/Internet Explorer)—refused to adopt NaCl. They viewed it as a proprietary Google technology that fragmented the open web.

For IP camera users, this plug-in essentially acts as a decoder or interpreter for the proprietary or legacy video formats used by many surveillance hardware manufacturers, such as Hikvision or Dahua, that do not natively support HTML5 video streaming.

was an open-source sandbox technology developed by Google to allow web applications to run compiled C and C++ code at near-native speeds directly in the browser. For IP camera users, this plug-in essentially acts

: Many legacy IP cameras, digital video recorders (DVRs), and network-attached storage (NAS) devices used NaCl plugins to decode and stream real-time H.264/H.265 video feeds directly into browser tabs without lagging.

Native Client allowed developers to build high-performance web applications—such as 3D games, photo editors, and complex simulations—that could harness the full computational power of a client's CPU while remaining isolated from the rest of the system for security. Chrome for Developers

Running native desktop code inside a browser poses massive security risks. To combat this, the naclwebplugin relied on an inner and outer sandbox structure:

As the industry looked for a unified solution, Mozilla, Google, Microsoft, and Apple collaborated on a new open standard called . WebAssembly achieved the same goals as PNaCl—running compiled C/C++/Rust code in the browser at near-native speeds—but it did so with universal browser support, cleaner integration with JavaScript, and a more secure, standardized design. 5.
