Deploying them was annoying.</p> <p>This month we tried compiling a couple to WebAssembly and running them with a single lightweight host. The results:</p> <ul> <li>Startup time dropped a lot</li> <li>One host process instead of three runtimes</li> <li>Sandboxing came for free</li> </ul> <p>The catch is tooling. Getting a Python toolchain to WASM is still fiddly, and debugging is not great.</p> <p>For small, stable tools it's a win. For anything that needs native libraries, I'd wait.</p> <p>I'm learning WebAssembly more deeply now, mostly the module and memory model. It's a good reminder that "just compile it" hides a lot.</p> devops webassembly tools
