Pick UptimeRobot if the number that decides it is how many URLs you can watch for nothing: 50 free monitors at 5-minute checks is more than anyone else on this page gives away, and its entry paid plan is the cheapest here.
Alternatives
Uptime monitoring alternatives, compared
Every product below is one we are regularly compared against, and each card says when to pick it rather than us. The figures in these summaries are the ones on the full comparison behind each name, and every comparison names its sources and the date they were read. Most quote the company’s own pricing or documentation. Two cannot: Pingdom’s pricing page would not show us its prices, and Freshping’s own pages are no longer served, so those two quote third-party pricing trackers and say so on the page. Open the comparison to see the source for anything here.
A few things are worth knowing before any of it. Uptimely probes from a single vantage point, so it cannot tell a regional outage from a global one the way a multi-location checker can. Its scripted checks run in a sandbox rather than a real browser, so they cannot walk a page a customer would see. It has no page-speed tests, and its server monitor reports from Linux hosts only. And it is a hosted service with no self-hosted edition. If any of those is your requirement, the right answer is on this page and it is not us.
Pick Better Stack if you want the telemetry depth in the same product as the checks — logs, traces, metrics, real-user monitoring and session replay — or if 30-second uptime checks are a hard requirement.
Pick OneUptime if you want to run the software yourself: it is open-source and self-hostable, and it covers status pages, incidents, on-call and telemetry, so none of your monitoring has to live on somebody else's infrastructure.
Stay with Pingdom — with SolarWinds Observability, really — if the mature global synthetic network and real-user monitoring are what you are paying for, or if the wider SolarWinds suite is where your team is heading anyway.
Pick Uptime Kuma if you are happy running the box yourself and one person owns the monitoring — it is free, MIT-licensed, up in one container, and its 90+ notification integrations are wider than any hosted product's.
Freshping cannot be chosen any more: Freshworks disabled free accounts on 6 March 2026 and stopped renewing paid subscriptions from the same date, which is the only reason this entry exists.
Pick Atlassian Statuspage if status communication is the requirement and the monitoring is already handled — its incident-communication workflow, 150+ third-party components and audience-specific pages are the deepest in the market.
Pick Checkly if the thing you need watched is a user journey rather than a URL — a login, a checkout, a signup — and you want those checks written as Playwright scripts that live in the repository and ship with the feature.
Pick StatusCake if you want one subscription covering page-speed, SSL, domain and server checks alongside uptime, or if testing from many countries matters more to you than what happens after the alert fires.
Pick PagerDuty if on-call is a practice rather than a rota — many teams, formal incident roles, custom incident types, workflow automation and governance — and you already have monitoring that can page it.
Pick Oh Dear if you want one product watching everything about a site rather than just whether it answers — broken links, mixed content, sitemaps, DNS blocklists, Lighthouse scores — and you want every outage confirmed from a second location before anyone is woken.
Stay on Atlassian's own path, Jira Service Management, if your team already lives in Jira and routes alerts from many monitoring tools, since Atlassian says it will sync most Opsgenie data and configuration across automatically.
Pick Grafana Cloud IRM if your alerts already live in Grafana: it is OnCall's direct successor, it is free for 3 active IRM users a month, and Grafana Cloud's own synthetic checks can sit beside it.
The other side
When Uptimely is the one to pick
When the checks and everything that happens after them should be one product on one bill: uptime monitoring, a public status page with subscribers and a custom domain, incidents with states and timelines, and on-call duty policies with escalation — all of it on the free plan too, not just the paid one. Pricing is flat rather than metered by check run, per site, per seat or per status page, so tightening an interval or adding a monitor does not change the invoice. And there is a public REST API, an OpenAPI schema, a typed SDK and an MCP server for the parts you would rather drive from your own pipeline.
