I built a heartbeat and uptime monitoring for developers
30 free monitors at 2-minute checks beats UptimeRobot's 5-minute free tier limit.

Uptime monitoring with 1-minute free checks, but UptimeRobot and Better Uptime already exist.

30 free monitors at 2-minute checks beats UptimeRobot's 5-minute free tier limit.
This is a clean, no-nonsense uptime monitor: 1‑minute checks, Slack/Discord/webhook alerts, custom-domain status pages and a usable free tier (3 monitors) — everything you actually expect from a monitoring starter kit. Nicely executed UX and sensible pricing make it an easy switch from UptimeRobot or Better Uptime, but the product doesn’t show a clear technical edge or novel feature to make it stand out in a crowded category.
Groups failing checks into single incidents so you stop ignoring alerts.
Single Go binary beats Uptime Kuma for CLI-first teams who hate containers.
Instant DNS/SSL/uptime checks plus an API, webhooks and reusable check templates make this a handy tool to fold into CI and lightweight automation. It's not reinventing monitoring — think UptimeRobot/Pingdom-lite — but being free, API-first and run on the author's infra gives it practical appeal for teams that want quick programmatic checks and Telegram alerts. To become a standout it needs multi-region probes, richer alert routing/SLO exports and clearer scaling/retention guarantees.
Yet another uptime monitor, but $3/month undercuts Pingdom and UptimeRobot significantly.
