Keep Alive

FAQ

By developers. For developers. No bullshit.

Your services go to sleep. We fix that with a single click.

Everything you need to know about keeping your endpoints warm and your users happy.

What's the problem Keep Alive solves?

Free and low-tier hosting puts your apps to sleep after inactivity. Your users hit your endpoint, wait 10+ seconds for a cold start, and bounce. Game over.

Why not just use existing solutions?

Current options suck:

  • Cron jobs: Requires server configuration you might not have access to.
  • Uptime monitors: Bloated dashboards, excessive notifications, high costs.
  • Custom scripts: One more thing to maintain, deploy, and worry about.

How does Keep Alive fix this?

Single endpoint. One click. Your service stays awake. That's it.

  • No account setup
  • No complex configuration
  • No BS email notifications
  • Just works™

Is this actually free?

Yes. Free tier gives you:

  • Monitor up to 2 URIs
  • Default 5-minute ping interval
  • Basic status monitoring

Only need more when using at scale? Subscribe.

What does the paid tier include?

Everything in free, plus:

  • Unlimited URIs
  • Custom ping intervals (down to 1 minute)
  • Request customization (headers, methods, body)
  • Response validation
  • Advanced logging

Real-world scenario: Free Render Web Service

Render's free tier puts your service to sleep after 15 minutes of inactivity. Your backend takes 30+ seconds to spin up again.

User experience: Click. Wait. Wait some more. Close tab. Never return.

Keep Alive solution: Add your Render URL, we ping it every 5 minutes, it stays warm. Your users never wait again.

Real-world scenario: Serverless Function Cold Starts

Serverless functions on AWS Lambda, Vercel, or Netlify go cold after inactivity. First request triggers a cold start, slowing down critical API responses.

Normal approach: Accept the performance hit or implement complex warming solutions with CloudWatch events or third-party services.

Keep Alive approach: Paste your function URL, we keep it warm. One and done.

Real-world scenario: Railway Free Tier Sleeping

Railway's free tier provides 500 hours/month but puts services to sleep to conserve your hours.

Common workaround: Custom cron job on another service to ping your application (more infra to manage).

Keep Alive solution: Add your Railway URL, customize the ping interval to your usage patterns, keep your app responsive while still managing your free tier hours.

Privacy & Security

We don't store your endpoint response data. We only track URI status and response time.

All requests are made server-side to avoid CORS issues and keep your endpoints secure.
