Tickstem – Python SDK for cron, uptime and heartbeat monitoring
Consolidates cron and uptime SDKs, but Cronitor and Healthchecks.io already own this space.

Heartbeat monitoring without the 4-tool sprawl, but early-stage and unproven at scale.
Backend developers and small team leads managing scheduled jobs, webhooks, and infrastructure alerts.
Cronitor · Hookdeck · BetterStack
I've been building web apps for 6 years and the same pattern keeps repeating: cron job silently fails → user reports it → I check logs → job hasn't run in days.
The fix exists — heartbeat monitoring — but it's spread across 4 tools that each cost as much as a full SaaS subscription. Cronitor for cron, Hookdeck for webhooks, MXToolbox for email, BetterStack for uptime. Most small teams skip half of them and find out the hard way.
Runmon is one place for all of it.
Starting with cron job monitoring because it's the most painful and most ignored. Setup is 60 seconds — you get a ping URL, append && curl https://runmon.dev/{id}/ping to your existing cron, done. No agent, no config files, no infra changes.
Webhook inspector, email deliverability, and uptime monitoring are next.
Waitlist at runmon.dev — would genuinely love to know which of these has burned you before.

AI assistant for cron debugging, but Cronitor and Healthchecks already monitor jobs well.
30 free monitors at 2-minute checks beats UptimeRobot's 5-minute free tier limit.
TUI and web dashboard for ARQ when the library has no built-in monitoring.
Combines uptime, PageSpeed, agent metrics, and Playwright flows—but UptimeRobot, Datadog, and New Relic already bundle these.
Telegram-first alerting is the product's personality — there are website/API/cron/SSL checks and an explicit "Start without email" flow that keeps signup friction low. The retro terminal UI is tasteful and suggests an MVP you can click through fast, but it doesn't yet offer a clear feature advantage over established uptime tools unless Telegram-only delivery is your hard requirement.
