FAQ

Frequently Asked Questions

Why do free cloud providers sleep?+

Free hosting tiers hibernate idle containers after 15 minutes of inactivity to save compute resources. The next visit triggers a 40–50 second cold boot delay.

How does UpMe eliminate cold starts?+

UpMe sends lightweight HTTP pulses at randomized intervals between 1 and 5 minutes using real browser headers, keeping your container warm in RAM.

Is UpMe free to use?+

Yes. UpMe is 100% free forever for up to 5 concurrent backend services. No credit card or billing information needed.

Which cloud hosts and frameworks are supported?+

Any publicly accessible HTTP/HTTPS URL—including Node.js, FastAPI, Go, Python, Spring Boot, and Docker containers hosted on any cloud platform.

Will keep-alive pings consume my compute budget?+

No. Pulses take under 100ms and use negligible CPU and bandwidth, keeping you well within free tier limits.
