If you already run scheduled HTTP work on a dedicated scheduler, you are most of the way to uptime monitoring without realizing it. An uptime monitor is just an HTTPS endpoint, fired on a cadence, with an alert when it stops answering 200. That is the exact shape of a cron job. So before you open a second tab, create a second account, and wire a second alert inbox, the question worth asking is: should "is my site up?" and "did my 5am job run?" really live in two different tools?
Crontap's answer is no. Point it at a URL, pick an interval, and you get uptime monitoring in the same dashboard, on the same bill, with the same alert pipeline you already use for your scheduled jobs. This post is the honest head-to-head: where Crontap's one-dashboard wedge wins, where UptimeRobot, Better Stack, and Pingdom still win, and how to stand a monitor up in under a minute.
Start where you already are: uptime next to your cron
Crontap was built for developers firing scheduled HTTPS work: replace wp-cron, beat the Vercel Cron hourly limit, put a real timezone-aware scheduler in front of *.fly.dev or a Railway service. Uptime monitoring ships in every account, including Free, so adding a monitor on a URL you already cron is a one-click affordance, not a vendor onboarding.
What you actually get:
- 1-minute checks on Pro, the same floor as UptimeRobot's paid tier. Free runs a daily probe, which is enough to watch a homepage or a status page.
- 90 days of history at a glance. Every monitor charts daily uptime in a status-page-style bar row, switchable between 7, 30, and 90 day windows. Same visual language as the public status pages you already read.
- One alert pipeline. When a monitor flips from
uptodown, the same notification email already wired to your failed scheduled jobs fires. When it recovers, you get aRecoveredemail. The failure threshold is configurable (default 2 consecutive misses) so a single blip does not page you. - The rest of the platform comes along for the ride. Because the monitor lives next to your schedules, the same account can run an LLM over a job's response to summarize or normalize it, fan results out to Zapier / Make / n8n, and keep historical logs of every run. Uptime is one feature inside a scheduler, not a standalone silo you have to babysit.
Two things to be straight about, because credibility matters more than a clean pitch: Crontap's uptime probes run from a single region as anonymous GETs, and monitor alerts are email-only today. Slack / Discord / webhook routing for monitors is on the near roadmap (your scheduled-job failures already route to all of those). If you need multi-region probing or a public status page on a custom domain right now, jump to the dedicated-tool checklist at the end first.
Where the dedicated tools still win
The marketing pages all read the same. The differences that actually show up in a developer's calendar are: minimum probe interval (free and paid), where alerts land, how many monitors fit before the price jumps, and whether the dashboard is one you already have open. On the absolute-capability axes (multi-region probes, public status pages, SSL expiry tracking, latency percentiles) the dedicated tools win outright. The honest question is whether you need those, or whether "is this URL responding 200, fast enough, every minute?" is the actual job.
UptimeRobot
UptimeRobot's free tier is generous on monitor count: 50 HTTP monitors at a 5-minute cadence, email alerts, plus a public status page. The paid lane (Solo / Team) takes you to 1-minute checks, with multi-region probing. The dashboard is fine, the docs are fine, the Slack / Discord / Teams integrations are fine.
Where it bites: the second-tool tax. You add a monitor, it pages you, you fix the issue, you move on. The next time a scheduled job stops firing on a different platform, you are back on a different dashboard, with a different audit log, looking at a different definition of "down".
Better Stack (formerly Better Uptime)
Better Stack is the modern-feeling option of the three. Free tier: 10 monitors at 3-minute checks. Paid: 30-second checks. The on-call rotations and incident-management stack are genuinely well thought through, especially for teams that already have a paging culture.
Where it bites: it is an incident-management product first and a probing product second. If you are a one-developer SaaS or a small backend team with no on-call rotation, you are paying for incident-management surface area you do not use.
Pingdom
Pingdom is the enterprise option of the three. 1-minute minimum check interval, paid only. Multi-region. Real-user monitoring. Tied to the SolarWinds suite.
Where it bites: pricing ramps fast for individual developers and small teams, and the workflow assumes you are paying for a broader observability footprint, not a focused uptime tool.
Side-by-side
| What | Crontap | UptimeRobot | Better Stack | Pingdom |
|---|---|---|---|---|
| Lives next to your cron | Yes | No | No | No |
| Same bill as your cron | Yes | No | No | No |
| Paid min interval | 1 min | 1 min | 30 sec | 1 min |
| Free min interval | 1 day | 5 min | 3 min | (paid only) |
| Free monitor count | 1 | 50 | 10 | 1 |
| 90-day history view | Yes | Yes | Yes | Yes |
| Email alerts | Yes | Yes | Yes | Yes |
| Slack / Discord / webhook | Roadmap (monitors) | Yes (paid for some) | Yes | Yes |
If your top-three needs are "lots of free monitors at 5-minute cadence", "30-second checks", or "deep incident-management workflow", then UptimeRobot, Better Stack, and Better Stack respectively are the right answers. If your top need is "I am already paying for one HTTPS scheduling tool, please do not make me pay for, log into, and triage a second one", that is the Crontap shape.
Setup, click by click
The minimum walkthrough on Crontap looks like this. (For the in-depth feature page, see /uptime.)
- Log in with the same account you use for scheduling. There is nothing to set up: uptime ships in every account.
- Go to the
Uptimetab in the topbar. - Click Add monitor, paste the URL you want probed, pick an interval (1 minute on Pro, 1 day on Free), submit.
- Click Run probe now to confirm the URL responds correctly. The bar chart starts populating from the next cron tick onwards.
- Optional: change the failure threshold (default 2 consecutive failed probes before flipping to "down") on the detail page.
When the monitor flips from up to down, the existing global notification email list (the same one already wired up for failed scheduled jobs) receives an email. When it recovers, you get a Recovered email. No new inbox, no new vendor.
When you actually want a dedicated uptime tool
Honest checklist of when you should pick one of the three above instead:
- You need probes from 5+ distinct geographies and care about the regional latency breakdown.
- Your team is large enough that on-call rotations, incident management, and SLA reporting are first-class concerns. Better Stack is genuinely good at this.
- You want a public status page on a custom domain today (Crontap's roadmap, not v1).
- You are already paying for SolarWinds / Pingdom and the marginal cost is zero.
For everything else (most one-developer SaaS, most small backend teams, most "I just need to know when this URL stops answering" cases) pairing uptime with the cron tool you already have is the lower-friction answer. That is the wedge.
