I Tried Deploying a WASM App on OSC My Apps with Codex — Here’s What Worked (and What Didn’t)

WebAssembly (WASM) is one of those technologies that feels like it should change how we build backend services - but the real question is: how well does it actually work in practice? I recently tried building and deploying a WASM-based Pixel Art Generator on OSC My Apps using Codex and the OSC MCP Connector. This post walks through the process, what worked smoothly, and where things got a bit messy. If you haven’t worked with WASM before, the idea is pretty simple.
