Uptime.com covers website and API monitoring, private checks and status pages, with plans starting at $9. The alternatives below range from open-source monitoring you run yourself to hosted observability platforms. They are not all drop-in replacements: some focus on metrics or broader telemetry rather than uptime checks. Compare the checks and integrations you rely on, then verify API access, rate limits, data export and pricing at your expected usage before migrating.
01Why people leave Uptime.com
Starting price may not reflect scale
The $9 starting price does not show what your check volume, private checks or status pages will cost as usage grows.
Validate developer interfaces first
Before building automation around Uptime.com, confirm API coverage, authentication, rate limits and data export with the vendor.
Consider self-hosting
If controlling where monitoring runs matters, compare Uptime.com with self-hostable options such as Prometheus and Zabbix.
02The alternatives, ranked by fit
- Self-hosted metrics
PrometheusPrometheusPrometheus is an open-source, self-hostable option for teams monitoring systems and services, especially in Kubernetes and cloud-native environments. It offers local metric storage and PromQL without usage fees, so infrastructure costs replace a per-use monitoring bill. It is not a like-for-like uptime service: plan to configure and operate the monitoring stack, and verify how your checks and alert workflows will migrate.
Trade-off: You run the servers and handle setup, operations and migration.

Freefree plan - Self-hosted infrastructure
ZabbixZabbixZabbix is open source and self-hostable, with no per-device license fees listed. It suits teams that want to run infrastructure monitoring themselves or need multitenant operations. Its free plan avoids a listed starting price, but hands-on setup and tuning are part of the trade. Before switching, map your existing checks and alert workflows, and confirm the API and export capabilities you need.
Trade-off: Setup and tuning take work; verify the developer interfaces you need.

Freefree plan - Telemetry dashboards
GrafanaGrafanaGrafana fits teams consolidating telemetry or already using OpenTelemetry or Prometheus. It is open source, has a free plan, and starts at $19; the bill can grow with telemetry use. This is a broader observability choice than a dedicated uptime-check replacement, so compare the data sources, dashboards and alert workflows you need to move before committing.
Trade-off: Telemetry use can increase costs; check fit for your existing checks.

$19/mofree plan - Hosted observability
New RelicNew RelicNew Relic is a hosted option for teams consolidating observability and incident response across applications and infrastructure. The listed starting price is $10, with a free plan tied to an ingest allowance. That can suit teams beginning within the allowance, but model expected ingest and user costs. Check API access, export and migration requirements against your current monitoring workflows.
Trade-off: Ingest and user costs need review as usage grows.

$10/mofree plan - Cloud observability
DynatraceDynatraceDynatrace is a broad observability and automation option for teams working with Kubernetes, cloud-native systems, tracing and user monitoring. Its listed starting price is $7. It may fit a move toward consolidated observability rather than a narrow uptime-check replacement. Compare the cost at your expected usage, and verify integrations, API access and data export before migrating.
Trade-off: Pricing and integration details need checking before production.
7.1/10from
$7/mo - Unified observability
DatadogDatadogDatadog suits teams consolidating observability and security across Kubernetes and cloud infrastructure, or building AI operations workflows. Its listed starting price is $500, so compare expected usage costs with Uptime.com rather than treating the entry price as a direct equivalent. The broader platform may change your monitoring architecture; verify telemetry needs, API access and data export before moving checks.
Trade-off: Usage costs and telemetry hygiene need close management.

Questions people ask
Which Uptime.com alternative is open source?
Prometheus, Zabbix and Grafana are listed as open source. Prometheus and Zabbix are also self-hostable. Their costs shift toward infrastructure and operations rather than a listed per-use fee, so budget for running and maintaining the monitoring stack.
Which alternative is cheapest?
Prometheus is listed from $0 with a free plan, while Zabbix has a free plan and no listed starting price. Hosted options listed here start at $7 for Dynatrace, $10 for New Relic and $19 for Grafana. Compare expected usage and included features, not starting prices alone.
What should developers check before migrating?
Inventory your checks, private infrastructure, status pages and alert workflows. Then confirm API coverage, authentication, rate limits, SDK support and data export with each vendor. For usage-priced platforms, estimate the bill using your expected telemetry or check volume before moving production monitoring.
