Pulsy vs Cronitor
The open-source alternative for uptime and TLS monitoring
Cronitor bundles cron monitoring, uptime checks, and performance insights as a closed-source hosted product. If the uptime half is what you are paying for, Pulsy does that as open-source software under AGPL-3.0 — free forever on your own infrastructure, or managed on Pulsy Cloud with flat plans. Cronitor's job monitoring has no Pulsy equivalent, so be clear which half you need.
Where Pulsy differs from Cronitor
- Open source (AGPL-3.0) — self-host free forever with every capability on.
- Flat Cloud plans, or no bill at all when you run it yourself.
- TLS-expiry alerting, incident grouping, and custom-domain status pages included everywhere.
- Localized dashboard in five languages with full right-to-left support.

Switching from Cronitor is painless

Frequently asked questions
- Is there an open-source Cronitor alternative?
- For the uptime and TLS side, yes — Pulsy is AGPL-3.0 and free to self-host. For cron and scheduled-job monitoring, Pulsy is not a replacement; Healthchecks.io is the closer open-source equivalent there.
- Does Pulsy monitor scheduled jobs?
- No. Pulsy makes outbound HTTP checks on a schedule; it does not accept heartbeat pings from your jobs.
- What does Pulsy cost?
- Self-hosted, nothing — free forever under AGPL-3.0 with no monitor limit. Pulsy Cloud has a free tier and flat paid plans from $12/mo.
- Can I keep my status page on my own domain?
- Yes. Custom domains for status pages are included, self-hosted and on Cloud.
