How to read the cells. "No" means the feature does not appear on the vendor's pricing, product, documentation or API pages. "No native integration" means the vendor's own integration list has no such entry, although webhooks can still reach the service. "Not compared" means we found no vendor page that settles the question, so we make no claim. RUM collects performance data from real visitors' browsers. A heartbeat monitor alerts you when a scheduled job fails to check in.

Each vendor: strengths and who should stay

Pingdom

Pingdom has no free plan, only a 30-day free trial (Pingdom sign-up page). Paid synthetic monitoring starts at $18 a month billed monthly, or $16.50 a month billed annually, for 10 uptime checks, 1 advanced check and 50 SMS alerts. 100 uptime checks with 20 advanced checks cost $149 a month billed monthly (Pingdom pricing, checked October 17, 2026).

  • Strengths. Transaction checks run in a real Chrome browser (Pingdom transaction monitoring), and an advanced check is either a transaction or a page speed check (Pingdom advanced checks documentation). Public status pages are included in all plans (Pingdom uptime monitoring). The API supports HTTP, TCP, ping, DNS, UDP, SMTP, POP3 and IMAP checks (Pingdom API reference). RUM is a separate product at $18 a month for 100,000 pageviews on the pricing page, although the Pingdom RUM page still says "Starts at $10 per month".
  • Limits. The shortest check interval is one minute (Pingdom API reference). Logs, metrics and traces are not in Pingdom's own plans: pingdom.com lists log management (SolarWinds Loggly) and infrastructure and application monitoring (SolarWinds AppOptics) as separate products. The RUM page lists no session replay.
  • Who should stay. Stay with Pingdom if you already run uptime, transaction checks and RUM there, or you need UDP or mail-server checks with status pages under one plan. Consider Site Qwality if you want a permanent free plan, or logs, metrics, traces and session replay without separate products. More detail on our Pingdom alternative page.

UptimeRobot

UptimeRobot's free plan covers 50 monitors at a 5-minute interval, with HTTP, port, ping and keyword monitors and one basic status page. Its terms say the service is "available for any use, including commercial and business use" (UptimeRobot terms). Paid plans in US dollars, monthly then billed annually per month: Solo $13 or $12 for 10 monitors at 60 seconds, Team $46 or $39 at 30 seconds, and Scale $98 or $79 at 15 seconds (UptimeRobot pricing, checked October 17, 2026).

  • Strengths. The largest free monitor count in this comparison. Paid plans add heartbeat (cron) monitors, DNS and UDP monitors, API monitoring, and SSL and domain expiry monitoring. Discord alerts are on the free plan, and Slack, Microsoft Teams, Mattermost and Telegram are on paid plans (UptimeRobot pricing). UptimeRobot says it is SOC 2 compliant, with the report available on request (same page).
  • Limits. Its API has no scripted multi-step browser monitor type (UptimeRobot API specification), and its pricing page lists no RUM, session replay, logs, metrics or traces. It has no native on-call scheduling and integrates with tools such as PagerDuty and Zenduty (UptimeRobot integrations).
  • Who should stay. Stay with UptimeRobot for simple HTTP, port and ping checks across many endpoints, or if free monitor count matters most. Our free plan is 100,000 checks a month, which is about 11 monitors at 5-minute intervals from one location (100,000 divided by 8,640 checks per monitor in a 30-day month). Consider Site Qwality if you need browser flows, RUM or telemetry in the same product. More detail on our UptimeRobot alternative page.

Better Stack

Better Stack's free plan, labeled "for personal projects", includes 10 monitors and heartbeats, 1 status page, Slack and email alerts, 3 GB of logs and 3 GB of traces (each retained 3 days), 30 GB of metrics, 5,000 session replays and 100,000 exceptions a month. Paid uptime is licensed per responder at $34 a month, or $29 billed annually. Extra 50-monitor packs are $25 a month ($21 annual). Checks run as often as every 30 seconds, and Playwright browser checks cost $1 per 100 minutes (Better Stack pricing, checked October 17, 2026).

  • Strengths. The closest match to Site Qwality's scope, with larger free telemetry and session replay allowances. On-call scheduling is included with a responder license. Uptime check types include TCP and UDP port, ping, SMTP, POP3 and IMAP. The pricing page lists SOC 2 Type 2 and prices Europe, United States and Singapore regions separately.
  • Limits. Its integration documentation lists Slack, Microsoft Teams, PagerDuty, webhooks and others, but no native Telegram or Discord (Better Stack integrations documentation, Better Stack integrations catalog). The free plan allows only Slack and email alerts. Better Stack labels the free plan for personal projects, so read its terms before relying on it for a business.
  • Who should stay. Stay with Better Stack if you want the biggest free telemetry and replay allowance, UDP and mail-server checks next to telemetry, SOC 2 Type 2 or a Europe region. Consider Site Qwality if you prefer to choose capacity per product in a calculator, want Telegram or Discord alerts, or want on-call priced in packs (25 responders for $50 a month, unlimited for $150) rather than per license. More detail on our Better Stack alternative page.

StatusCake

StatusCake has a free plan at $0: 10 uptime monitors at a 5-minute interval, 1 page speed monitor, 1 domain monitor and 1 SSL monitor. Superior is $24.49 a month billed monthly ($20.41 billed annually) for 100 uptime monitors at 1 minute. Business is $79.99 ($66.66 annual) for 300 uptime monitors at 30 seconds. Paid plans come with a 7-day free trial (StatusCake pricing, checked October 17, 2026).

  • Strengths. Push (heartbeat) monitoring is included with every plan (StatusCake push monitoring guide). Test types include HTTP, TCP, ping, DNS, SMTP and SSH (StatusCake API reference). Alerts go to 14 platforms, including Slack, Microsoft Teams, Discord, Telegram, Mattermost and PagerDuty (StatusCake integrations).
  • Limits. Public status pages are a separate product, StatusCake Pages, from $14.95 a month billed monthly ($12.46 annual) for 1 page (StatusCake status pages). Its pricing and API pages list no RUM, session replay, logs, metrics, traces or real-browser multi-step checks.
  • Who should stay. Stay with StatusCake for inexpensive uptime, page speed, domain, SSL and TCP or ping checks. Consider Site Qwality if you want status pages, browser flows, RUM, session replay or telemetry on the same platform. More detail on our StatusCake alternative page.

Datadog

Datadog prices each product on its own unit. List prices below are billed annually unless noted (Datadog price list, checked October 17, 2026): Infrastructure Pro $15 per host a month ($18 monthly), APM $31 per host ($36 monthly), log ingestion $0.10 per GB, Synthetic API tests $5 per 10,000 runs, browser tests $12 per 1,000 runs, On-Call $20 per seat, and the Session Replay add-on $2.50 per 1,000 sessions ($3 monthly) on top of RUM. Incident Management is $30 per seat and includes unlimited status pages with custom domains. Its pricing page lists a free Infrastructure plan for up to 5 hosts with 1-day metric retention (Datadog pricing).

  • Strengths. It covers every category in the table. Synthetics supports HTTP, gRPC, SSL, DNS, WebSocket, TCP, UDP and ICMP tests (Datadog Synthetic Monitoring), plus browser tests. Datadog also documents an EU site hosted in Germany (Datadog sites documentation).
  • Limits. Because each product bills on its own unit, your total depends on hosts, log volume, sessions, seats and test runs, so price your own workload against the list before comparing. Its integration catalog has native Slack and Microsoft Teams entries but none for Discord or Telegram (Datadog integrations).
  • Who should stay. Stay with Datadog if you need host and container infrastructure monitoring or application performance monitoring across a large estate, or an EU site. Consider Site Qwality if your main need is website and API monitoring with telemetry and a free allowance on each product. More detail on our Datadog alternative page.

Where Site Qwality is weaker

  • No UDP or mail-server checks. Site Qwality runs HTTP, TCP port, ping (ICMP), TLS and DNS checks (our uptime monitoring page). Ping runs from 8 of our 30 locations, and port 25 cannot be checked because every cloud provider we check from blocks it. Pingdom, UptimeRobot, Better Stack and Datadog list UDP checks, and Pingdom, Better Stack and StatusCake list mail-server checks, as the vendor pages linked above show. If you need those, use one of them, alone or alongside us.
  • No SOC 2 report, no ISO 27001 certificate, no EU-hosted deployment. We hold neither attestation and do not run dedicated or EU-hosted deployments (our pricing page). The platform runs in a single AWS region, us-east-1 (our FAQ). Better Stack lists SOC 2 Type 2 and a Europe region, UptimeRobot says it is SOC 2 compliant, and Datadog documents an EU site. If procurement requires these, we are not the right pick today.
  • Some checks run from one location. HTTP checks can run from several locations on AWS, Google Cloud and Microsoft Azure, and browser checks from several AWS locations, but TLS certificate, domain expiry and DNS record checks run from Virginia (AWS) only (our locations page).
  • Different free replay and telemetry allowances. Our free plan has 100 session replays a month with 30-day retention and 5 GB each of logs and traces with 7-day retention, plus 2,000 average active hourly metric series. Better Stack's free plan lists 5,000 session replays, 3 GB of logs and 3 GB of traces (each retained 3 days), and 30 GB of metrics.
  • Fewer free monitors than UptimeRobot. About 11 monitors at 5-minute intervals against UptimeRobot's 50.
