Anti-Detection Jitter (1 to 5 Minutes)
Ordinary pingers trigger requests at exact intervals (e.g. exactly every 5:00 minutes), which cloud hosting heuristics easily flag and suspend. UpMe randomizes each pulse (e.g. 74s, 218s, 142s) to mirror authentic visitor behavior.
ORIGIN RUNTIME HIT
GET /health HTTP/1.1
User-Agent: Chrome/124 Desktop
Cache-Control: no-cache
Real Browser User-Agents
Requests send modern desktop Chrome, Safari, and Firefox headers with cache-busting directives, guaranteeing the pulse hits your real application runtime rather than a CDN cache.

Universal Keep-Alive

Works with any HTTP or HTTPS service

Keep your cloud instances running hot without spin-down interruptions:

WEB APPS

Free Tier Web Services

Cloud providers hibernate idle servers after 15 minutes of quiet time. UpMe keeps them hot in memory so they never sleep.

APIS

REST & GraphQL APIs

Eliminates frustrating 45-second latency spikes when mobile clients, websites, or external webhooks call your API.

SERVICES

Background Microservices

Stops containerized microservices from entering idle states, ensuring asynchronous tasks and queues are processed immediately.

DEMOS

Portfolio & Demo Projects

Guarantees your full-stack demo apps load in milliseconds when recruiters, clients, or evaluators test your work.

Our automated stealth worker pulses your endpoint continuously so it never hibernates.

Common Questions

Frequently Asked Questions

Everything you need to know about eliminating backend cold starts.

Why do free cloud providers like Render and Railway sleep?+

Free-tier web services automatically hibernate after 15 minutes of inactivity to save compute resources. When a new user visits, your container must cold-boot from scratch, causing a painful 30 to 50-second delay.

How does UpMe eliminate cold starts?+

UpMe sends lightweight HTTP pulses at randomized intervals (between 1 and 5 minutes) using real modern browser user-agents. This keeps your service hot in RAM so all incoming visitor requests respond in milliseconds.

Is UpMe completely free to use?+

Yes! UpMe is 100% free forever for up to 5 concurrent backend services. No credit cards, billing, or hidden fees are required.

Which cloud hosts and backend frameworks are supported?+

UpMe works universally with any publicly accessible HTTP/HTTPS URL. It supports Render, Railway, Fly.io, Heroku, Supabase, Koyeb, Node.js, Express, FastAPI, Django, Go, Spring Boot, and Docker containers.

Will keep-alive pings consume my free tier compute budget?+

UpMe pings take under 100ms and use near-zero CPU and memory. On platforms like Render and Railway, they ensure maximum availability without exceeding bandwidth quotas.
