Dead-Man's Switch API for Background Task Monitoring
A simplified monitoring tool for independent developers and small teams to ensure cron jobs, database backups, and scheduled scripts are running successfully. It alerts users immediately if a expected signal is missing.
Why this matters
When you are managing scripts, database backups, or periodic background tasks, it is terrifyingly easy for them to fail silently. You set up a scheduled job, assume it works perfectly, and only discover weeks later that your backups have been failing because a server disk was full. Traditional application monitoring suites are incredibly complex, expensive, and completely overkill for a solo developer just wanting to know if a script finished. You need a dead-simple utility where your task pings a unique endpoint upon completion, and if that ping does not arrive, you get alerted immediately.
- · Built for Solo developers, indie hackers, and small engineering teams running self-hosted infrastructure..
- · Most likely monetization: freemium.

MVP Scope · 1–2 weeks
- Design a high-throughput database schema to handle rapid incoming ping requests.
- Build an API endpoint that registers pings and updates the last-seen timestamp for specific job IDs.
- Develop a background worker that constantly sweeps the database for jobs that have missed their check-in window.
- Implement basic email alerting using a transactional email service when a failure is detected.
- Create user authentication and a basic project management data structure.
- Build a minimalist web dashboard displaying green/red status indicators for all configured tasks.
- Add a Slack webhook integration to send failure alerts directly to team channels.
- Implement rate limiting to protect the ping endpoints from abuse.
- Set up Stripe checkout for upgrading from the free tier to premium features.
- Write clear, copy-pasteable documentation for integrating the ping into bash, python, and node scripts.
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Competing against established, deeply integrated tools and highly successful open-source self-hosted alternatives.
- 2The target demographic of developers prefers to build this themselves rather than paying a monthly fee.
- 3Sustaining a reliable infrastructure that never misses a ping requires significant operational overhead, reducing profit margins.
