Nobody notices until a client does.</p> <p>So I built Keepalive, one dashboard that watches all three:</p> <ul> <li>Cron jobs: each one gets a unique check-in URL to call on success. Miss the expected schedule, get an alert.</li> <li>SSL certificates: checked on a schedule, flagged before they expire, not after.</li> <li>Domain registration: same idea, via WHOIS.</li> <li>Alerts: email, Slack, or a generic webhook, fired on any status change, including recovery, not just failure.</li> </ul> <p>Stack: FastAPI + SQLite + APScheduler, deliberately boring, one process, no queue, no separate worker. Deployed on Fly.io.</p> <p>It's free to try, no card required: <a href="https://keepalive-nandu.fly.dev" rel="noopener noreferrer">https://keepalive-nandu.fly.dev</a></p> <p>Would genuinely value feedback from anyone managing a handful of client sites or scheduled jobs, what's missing, what's confusing, what you'd actually pay for.</p> webdev showdev python opensource
