Every app below is a real server-rendered app whose VM has been fully shut down — zero CPU, zero RAM. The button sends a real HTTP request. The platform restores the entire virtual machine — running server, warm caches, JIT'd code — before your request reaches it. Watch how long that takes.
Timing is measured end-to-end from this page's server, and the
platform's own overhead is reported by the X-Hyperdrive-Wake-Ms
response header on the actual response. Woken apps go back to sleep after
5 minutes of silence — come back later and it'll be asleep again.
