Comparison
Pulsy vs Uptime.com
The open-source Uptime.com alternative
Uptime.com is a capable closed-source monitoring service aimed at businesses that want an SLA and a support contract. Pulsy covers the core of it — HTTP checks, TLS expiry, incident tracking, status pages on your own domain — as open-source software you can run yourself for nothing, or have managed on Pulsy Cloud with flat plans.
Where Pulsy differs from Uptime.com
- Open source (AGPL-3.0) — self-host free forever with the data on your own infrastructure.
- Flat plans on Cloud, or no bill at all self-hosted, instead of business-tier pricing.
- SLA reports, incident history, and custom-domain status pages without an enterprise upgrade.
- Localized dashboard in five languages with full right-to-left support.

Switching from Uptime.com is painless
Stand Pulsy up alongside, re-create your checks against the same URLs, and confirm alerts reach your channels before you switch. Because the software is AGPL-3.0, moving in-house later is always available to you — which is a different position from a service contract.
Frequently asked questions
- Is there an open-source Uptime.com alternative?
- Yes. Pulsy is AGPL-3.0-or-later, covering HTTP checks, TLS expiry, incidents, SLA reporting, and status pages. Self-host it free, or use Pulsy Cloud from $12/mo.
- Does Pulsy produce SLA reports?
- Yes. Self-hosted they are unconditionally available; on Pulsy Cloud they are part of the Team plan.
- Is there a support contract?
- Pulsy Cloud paid plans include priority support. Self-hosted support is the public issue tracker — if a contractual SLA on support response is a requirement, that is a genuine reason to prefer a commercial vendor.
- Can I monitor internal endpoints?
- Self-hosted, yes — deploy Pulsy inside your network and it can reach endpoints no external service can. That is one of the clearer advantages of self-hosting.
