Best Uptime Monitor 2026: Cheap, Reliable, No Surprises

For most indie devs and small teams, the best uptime monitor is Pulsetic Team at $19/mo: 50 monitors, 30-second checks from 15 regions, no commercial-use restrictions. If you are starting out and want zero cost, Better Stack free tier gives you 10 monitors, a status page, and 3-minute checks — commercially usable (unenforced gray area, more on that below). If your workload is cron jobs and heartbeats, Cronitor is the specialist. If you are deep in TypeScript and want monitoring-as-code, Checkly has no equal.

Who this is for

Indie devs, solo founders, and small teams running services on Cloudflare Workers, Fly.io, Railway, or a VPS. You want something that pages you when your service is down, shows you a status page you can share with users, and doesn’t charge enterprise rates. If you run Datadog for APM and PagerDuty for on-call at a company with a dedicated SRE team, you’re in the wrong article.

Freshping is not in this comparison. It shut down on March 6, 2026 — Freshworks deprecated it with under 8 weeks of notice and no migration tool. Former users: migrate to one of the options below.

What we tested

Plan tiers and pricing verified against each tool’s pricing page in May 2026. Check type coverage confirmed against feature docs. Reliability incident history sourced from IsDown (UptimeRobot) and StatusGator (Checkly). User sentiment pulled from G2 reviews, HN threads, and dev.to posts from 2024–2026.

Price

The cheapest path to 50 monitors with 30-second checks and multi-region verification:

Tool	50 monitors + 30-sec	Free commercial?
Pulsetic	$19/mo (Team)	Yes
Better Stack	~$50/mo (10 base + add-ons)	Gray area
UptimeRobot	$54+/mo (Enterprise)	No — banned Nov 2024
Checkly	$24–64/mo (Starter/Team)	Yes (Hobby)
Cronitor	~$100/mo	Yes (5-min on free)

Pulsetic’s Team plan at $190/year ($19/mo) is the most aggressive price-per-monitor in this field. You get 50 monitors, 30-second check intervals, 15 regions, unlimited status pages with custom domain, and Slack/Teams/Discord alerts. Additional monitors are $0.20/mo each. There is no commercial-use restriction.

The UptimeRobot situation deserves a hard paragraph. Since November 2024, UptimeRobot’s Terms of Service explicitly ban commercial use of the Free plan. Any revenue-generating site or business service is prohibited, and enforcement began December 2024. The HN thread from November 2024 was scathing — one commenter noted: “their free plan previously had no such restriction.” This is a bait-and-switch. The paid plans start at $7–9/mo but deliver 60-second minimum check intervals even on Team ($29–33/mo). You only get 30-second checks at Enterprise ($54+/mo). For the price, there is no reason to start here in 2026.

One more credibility note on UptimeRobot: IsDown tracked 20 incidents in the 90 days prior to this review, with a May 8, 2026 outage titled “Monitoring Checkers is down.” An uptime monitor that goes down is not a deal-breaker — everything has incidents — but 20 in 90 days at a median 8-minute duration is notable for a tool whose sole job is to catch outages.

Alerts and integrations

All five tools cover the basics: email, Slack, webhooks. The divergence is in SMS and phone calls.

Better Stack includes unlimited SMS and phone calls with the Responder plan ($29/mo). No separate credits, no surprise bills. UptimeRobot charges separately for SMS and voice at $3/10 credits, which adds up fast if you are on-call solo and your weekend is anything like your weekday.

Pulsetic charges $0.10/alert for SMS and calls on Solo+, which is reasonable for low-volume use. Cronitor includes SMS on Business tier; PagerDuty and OpsGenie integration available too. Checkly gives 100 SMS/mo on Starter and 200/mo on Team, then charges overages.

For webhook coverage: all tools support it. Better Stack, Cronitor, and Checkly support PagerDuty natively. Pulsetic does not — you would wire it through a webhook.

Check types

HTTP/HTTPS monitoring is table stakes. The interesting split is cron/heartbeat and browser transactions.

Cron and heartbeat monitoring — Cronitor is the specialist here. It understands cron syntax natively: you tell it a job should run every 15 minutes, and it alerts if the job fails to run or runs longer than expected, with configurable tolerance windows. Better Stack and Checkly both support heartbeat checks, but without schedule-aware alerting. If you run nightly builds, data pipelines, or serverless cron workers, Cronitor is the right tool regardless of what else you use.

Browser / Playwright checks — Checkly is native TypeScript/Playwright. The entire monitoring stack is code: checks live in .ts files, get reviewed in PRs, deploy via CLI or Terraform. This is what “monitoring as code” means in practice. Better Stack offers Playwright transaction monitoring at $1 per 100 Playwright-minutes (pay-as-you-go) — useful if you want a browser check without switching platforms. UptimeRobot and Pulsetic have no browser check support.

DNS monitoring — Better Stack and UptimeRobot support it natively. Pulsetic does not. Cronitor does. Checkly does not.

Check type matrix:

Check type	Better Stack	UptimeRobot	Pulsetic	Cronitor	Checkly
HTTP/HTTPS	✓	✓	✓	✓	✓
Keyword	✓	✓	✓ (Solo+)	✓	✓
TCP/port	✓	✓	✓	✓	✓
DNS	✓	✓	✗	✓	✗
SSL expiry	✓	✓	✓	✓	✓
Cron/heartbeat	✓	✗	✗	✓ (specialty)	✓
Playwright	✓ ($1/100 min)	✗	✗	✗	✓ (native)
Ping/ICMP	✓	✓	✓	✗	✗

Status pages

Better Stack gives you a status page on the free tier. The free page includes dark mode, incident update feeds, and embedded metrics. Custom domain (via CNAME) is listed on the pricing page but not explicitly designated as a free-tier feature — verify on the pricing page before relying on it at no cost. White-label (remove “Powered by Better Stack”) jumps to $208/mo — skip that unless you are an agency.

Pulsetic includes unlimited status pages on Team+, with custom domain and password protection. Organization tier adds white-label. Checkly includes status pages on all plans, custom domain on Starter and above. UptimeRobot’s free tier gives you one basic page with no custom domain. Cronitor’s basic page is free; branded custom domain is $25/mo extra.

Uptime monitor reliability

Better Stack has no major incidents documented in public trackers over the research period. Multiple G2 reviewers specifically call out accurate alerting and low false-positive rates. Checks fire from at least 3 locations and require agreement before alerting — that is the right default.

Cronitor has been running since 2014. Eleven years of independent operation with no notable incidents in this research period. For a bootstrapped tool, that longevity is a real signal.

Checkly has had 336+ incidents documented since June 2021 (nearly 5 years), all short-duration and publicly posted. The transparency is good — they post everything. Most were classified as “warn” and resolved within an hour.

Pulsetic has no major documented incidents, though the smaller user base means less public data.

Developer tooling

Checkly is the only tool in this comparison built around the idea that your monitoring config should live in Git. You write a check:

import { ApiCheck, AssertionBuilder } from 'checkly/constructs'

new ApiCheck('homepage-check', {
  name: 'Homepage is up',
  request: {
    url: 'https://yourapp.com/',
    assertions: [AssertionBuilder.statusCode().equals(200)],
  },
})

Run npx checkly deploy and it’s live. You can review monitoring changes in PRs. You can preview in CI before deploying. If your team already has TypeScript muscle memory, this is a natural fit. The Starter plan ($24/mo) covers 50 uptime monitors, 3,000 check runs, and 3 users.

Better Stack has a clean API and solid Terraform provider, but there is no “checks as code” model — configuration is click-ops or API calls.

Verdict

Pick Pulsetic Team ($19/mo) if: you want the cheapest path to reliable coverage — 50 monitors, 30-second checks, 15 regions, no commercial restrictions. This is the default recommendation for solo founders and small teams.

Pick Better Stack free tier if: you are starting out and want ≤10 monitors with a status page and 3-minute checks at no cost. Scale to Responder ($29/mo) when you need 30-second checks or phone/SMS alerts.

Pick Checkly ($24/mo Starter) if: your team is TypeScript-first and you want monitoring treated as code — checks in Git, reviewed in PRs, deployed by CLI. Also the right call if you need real Playwright browser checks.

Pick Cronitor if: you monitor cron jobs or heartbeats more than HTTP endpoints. Its schedule-aware alerting has no real equivalent in this list. Budget ~$30–50/mo once you add monitors and users.

Avoid UptimeRobot free tier for any commercial project — banned since November 2024. The paid plans are functional but overpriced relative to Pulsetic and Better Stack for comparable check intervals. The free-tier bait-and-switch erodes trust in ways that matter for a tool you rely on at 3am.

Caveats

Better Stack’s free tier says “for personal projects” in the fine print. Commercial enforcement is unenforced as of May 2026, but that could change. Pulsetic is bootstrapped — that’s a strength (can’t be sunset without warning) and a risk (small team, slower iteration).
