Deploy and Host high-vast on Railway

high-vast is a single-file Node.js benchmark that runs a known, controlled CPU and RAM load and logs its own resource usage over time. Instead of guessing how fast a trial's credit balance drains, you get real numbers: point it at your Railway trial and see exactly how many $/hour a given load costs — then use that rate to plan what your actual project will need.

About Hosting high-vast

Deploying high-vast is a one-click affair — Railway auto-detects Node via package.json and runs npm start. No database or external services required. Once live, it runs continuously, holding a fixed amount of memory and CPU load and printing periodic JSON stats to the deploy logs. You can hit the /stats endpoint anytime for live numbers, and cross-reference against Railway's own Usage tab to calculate your actual $/hour burn rate. Defaults are tuned for the free trial tier (1 vCPU / 0.5GB RAM), but every load parameter is adjustable through environment variables — no redeploy needed.

Why Deploy high-vast

Trial credits are billed by resource-hours, not by "did it survive" — pegging everything to 100% just gets the process OOM-killed and tells you nothing useful. high-vast runs a measured, known load instead, so the $/hour figure you get back is actually usable for planning. It's the fastest way to answer "how long will my trial credit actually last" with real data instead of a guess.

Common Use Cases

Measuring exactly how fast a Railway trial's credit balance drains under a known load, before committing real budget
Comparing $/hour cost at different RAM/CPU levels to right-size a real project's resource plan
Stress-testing a trial or low-tier plan's stability under sustained (but controlled) load
