"I built a Python compiler that runs in browser using WebAssembly"

“Great question!

Pyodide’s memory footprint is
actually one of its interesting
trade-offs:

Initial load: ~8MB download
(Python runtime + standard library)

Runtime memory: ~50-100MB
in browser RAM while active

How I handle it:
→ Lazy loading — Pyodide only
loads when user clicks Run
→ Single instance — load once,
reuse for all executions
→ Browser manages cleanup
automatically

The good news:
After first load it’s cached by
the browser — so repeat visitors
get instant startup!

For a beginner tool the trade-off
is worth it — no server cost at all.
