Your services should never fall asleep.
Sleepless is a lightweight, self-hosted cron monitoring service that keeps your free-tier web services awake by periodically pinging them on a schedule.
Perfect for platforms like Render, Heroku, or any backend that sleeps after inactivity — Sleepless ensures your APIs stay warm and responsive.
Built with Spring Boot 4, PostgreSQL, and fully Dockerized for easy deployment.
Free-tier hosting platforms often shut down inactive services, causing slow cold starts, increased response times, and sleeping APIs.
Sleepless solves this automatically by sending scheduled requests to your services and validating their responses.
