StackMachine vs Cloudflare Workers
Run real applications — not adapted ones. Full native language support, instant cold starts, and WebAssembly-level security.
Why teams choose StackMachine
Built on WebAssembly from the ground up — not bolted on as an afterthought.
Way Faster Cold Starts
- StackMachine cold starts in < 5 ms via Instaboot snapshots
- Even large apps (WordPress, LangFlow, Django) start instantly
- Cloudflare Workers Python: 800 ms+ due to V8 isolate + Pyodide warmup
Full Native Language Support
- Run Python, PHP, JS and more — natively on WASIX, not through Pyodide
- Full frameworks: FastAPI, Django, Flask, Starlette, WordPress
- Real library support: numpy, ffmpeg, pypandoc, pillow, streamlit, sqlalchemy
- Native WebSocket support built in
Full WebAssembly Sandboxing
- Each app in its own Wasm instance with separate memory
- Lightweight Wasm isolation — no heavy V8 snapshots required
- Compiled code pages shared read-only across tenants for higher density
- All host access (network, FS, I/O) explicitly mediated by runtime
No Code Adaptation Required
- Deploy existing apps as-is — no proprietary API adaptation needed
- No adapters, wrappers, or Lambda handlers
- Cloudflare: must adapt code to Workers API

| Python frameworks | FastAPI, Django, Flask, Starlette | Limited (no uvicorn, no pthreads) |
| Multithreading | ||
| Binary tools (ffmpeg, pypandoc…) | ||
| Sandboxing | Wasm isolation (lightweight) | V8 isolates + heavy snapshots |
