Read this page as one judge. Each weighs the same scores by what they care about.

The E-Commerce Operations Manager

Weighted verdict

Runs operations for an online shop selling garden furniture in Germany, Austria and Switzerland, with half the year's revenue between March and June. The homepage once answered 200 while the checkout threw an error for six hours. Wants the checkout and the payment page checked, not only the homepage, an SMS or call to whoever is on duty that night, and a report that shows the agency what the downtime cost.

Same scores as the panel view — this lens weights them the way this judge cares.

Checks, locations & failure confirmation

How this is scored

What can be monitored and how reliably a failure is detected: HTTP(S) with status code and keyword checks, TCP and port, ping, DNS records, SSL certificate and domain expiry, cron jobs and heartbeats, multi-step API checks with assertions, browser or transaction checks of a login or checkout, the shortest check interval, the number and regions of probe locations, the re-check from a second location before an alert, timeouts and response time thresholds, and private locations inside the customer's own network.

0 — Runs no checks of its own; a status page or alerting tool that only receives signals from other monitors.

3 — HTTP checks of a URL at a fixed interval with an up or down result; keyword, SSL, cron and the probe locations are basic or not described.

5 — HTTP(S), keyword, TCP or port, ping and SSL expiry checks, cron or heartbeat monitoring, an interval of one minute or less, several named probe locations, a failure confirmed from a second location before alerting, and response times recorded per check.

8 — Multi-step API checks with assertions on headers and body, browser or transaction checks of a user flow, DNS and domain expiry checks, sub-minute intervals, probe locations listed by city with the confirmation logic documented, private locations or agents for internal services, and maintenance windows that pause checks.

10 — Coverage and accuracy a reliability team runs on: every check type above with code-based checks (for example Playwright or scripted tests) in version control, location-specific thresholds, false-positive handling and probe health published, and the detection method documented so a result can be reproduced.

Report an error

The E-Commerce Operations Manager

Eight monitor types from HTTPS and TCP to DNS, SSL expiry and traceroute, plus real Playwright browser checks that can walk my checkout and payment flow, running as often as every ten seconds from 22 public locations with a failed check retried and confirmed from a second location before anyone is paged. Private agents for internal services and maintenance windows are there too; the locations are described by region rather than city, and I found no published probe health or probe IP list to allow-list. 3 7 8 12 13

Alerting, escalation & on-call

How this is scored

How the right person learns about a failure: alert channels (email, SMS, phone call, push app, Slack, Microsoft Teams, Telegram, webhooks), alerts to PagerDuty, Opsgenie or similar tools, escalation policies when an alert is not acknowledged, on-call schedules and rotations, acknowledge and resolve from the app, alert grouping and noise reduction, recovery notifications, maintenance windows that mute alerts, and whether SMS and calls are included or charged per message.

0 — No alerting at all; results can only be viewed in the dashboard.

3 — Email alerts and one or two chat integrations; escalation, phone calls and schedules are basic or not described.

5 — Email, SMS, a mobile push app, Slack, Microsoft Teams and webhooks, alerts forwarded to PagerDuty or Opsgenie, per-monitor alert contacts, recovery notifications, a delay or threshold before alerting, and maintenance windows that mute alerts.

8 — Phone call alerts, escalation policies with timeouts, on-call schedules and rotations with overrides, acknowledge and resolve from the app or chat, alert grouping, incident timelines with who did what, and the price of SMS and calls stated per country or included in the plan.

10 — On-call that replaces a separate incident tool: follow-the-sun schedules, escalation across teams, alert routing by service and severity, post-incident reviews generated from the timeline, and delivery of every alert channel monitored and reported.

Report an error

The E-Commerce Operations Manager

SMS to the on-call phone and a real voice call for the alerts that must never be missed are in, with run-based and time-based escalation, reminders every 5 to 30 minutes, per-channel delivery logging, and stated monthly quotas (100 SMS on Starter, 200 on Team, phone alerts on Team). What I did not find is a native on-call schedule or rotation — those live in PagerDuty or Opsgenie — nor incident timelines, acknowledge-from-app, or a per-country price for messages beyond the monthly quota. 6 8 12 14 15

Status pages & incident communication

How this is scored

How customers and colleagues are told: public status pages on a custom domain with SSL, components and component groups fed automatically by monitors or set by hand, incident updates and scheduled maintenance announcements, subscribers notified by email, SMS, RSS or webhook, uptime history shown per component, private or password-protected pages for internal teams or single customers, branding and custom CSS, several languages, page templates, and how the status page itself stays online when the main product is down.

0 — No status page of any kind.

3 — A public status page listing monitors with their current state; custom domain, incident updates and subscribers are basic or not described.

5 — Public status pages on a custom domain, components linked to monitors, incident updates and scheduled maintenance, email subscribers, uptime history per component, the vendor's branding removable, and a password-protected or private page option.

8 — Component groups, SMS, RSS and webhook subscribers with per-component subscriptions, private pages with single sign-on or IP restriction, several languages, incident templates, embeddable status widgets, audience-specific pages for single customers, and the status page hosting kept separate from the main service and documented.

10 — Incident communication end to end: incidents drafted from monitor events and approved by a person, updates published to the page, subscribers, chat and social channels at once, a full incident archive with post-mortems, status page uptime published, and accessibility of the page stated.

Report an error

The E-Commerce Operations Manager

Public pages on a custom domain with services and nested groups, automation rules that open an incident from a failing tagged check, post the first update and auto-resolve on recovery, email subscribers with verification plus RSS, Atom and Slack feeds, and a 90-day history per component with a documented uptime weighting. The captured pages show nothing on multiple languages, per-component subscriptions or embeddable widgets, and password protection as well as theme customisation only start on the Team tier. 5 16 17

API, monitoring as code & team administration

How this is scored

How the tool fits a team and a deployment pipeline: a documented REST API to create and read monitors, status pages and incidents, a Terraform provider, CLI or monitoring-as-code workflow, checks run from CI/CD before a deploy, bulk import of monitors, integrations with ticketing and chat tools, team members with roles, single sign-on (SAML) and SCIM, audit logs, several teams or client accounts in one organisation, white-label or client reporting for agencies, and two-factor authentication.

0 — No API, no team accounts; one login per account and monitors are set up only by hand.

3 — A web dashboard with a few team members; the API, roles and multi-client set-up are basic or not described.

5 — A documented REST API covering monitors and status pages, webhooks, team members with roles, two-factor authentication, bulk import or a CSV upload of monitors, and several projects, teams or client groups in one account.

8 — A Terraform provider or monitoring-as-code CLI with checks kept in version control, checks triggered from CI/CD, single sign-on (SAML), SCIM provisioning, audit logs, sub-accounts for clients with their own logins, and white-label client reports.

10 — Administration that scales across many teams and clients: every setting reachable by API and code with parity stated, granular roles per resource, SSO enforced with SCIM, audit logs exportable to a SIEM, and agency or reseller accounts with separate billing.

Report an error

The E-Commerce Operations Manager

Monitoring as code is the strongest card: a documented REST API with an OpenAPI spec, official Terraform and Pulumi providers, the CLI with test and deploy commands gating releases through GitHub Actions, GitLab, Vercel or Jenkins, plus SAML 2.0 for Enterprise, multi-factor authentication and multiple projects per account. I found nothing on SCIM provisioning, organisation-wide audit logs, or agency or client sub-accounts with their own logins and white-label reporting. 1 7 8 11 18 19

Uptime reports, data & the vendor's own reliability

How this is scored

What the record is worth and whether the monitor itself can be trusted: uptime and SLA reports per monitor and period, response time charts and percentiles, scheduled reports by email, client-facing reports, how long check results and incident history are kept, export of results by CSV or API, the vendor's own public status page and incident history, its SLA, the probe IP addresses and user agent published for allow-listing, and an open-source or self-hosted edition.

0 — No history of any kind; only the current state is shown.

3 — An uptime percentage and a response time chart per monitor; retention, export and the vendor's own status are basic or not described.

5 — Uptime and response time reports per monitor and period, SLA reports, scheduled email reports, the retention period of check results stated, CSV or API export, the probe IPs published, and the vendor's own public status page.

8 — Response time percentiles and breakdowns (DNS, connect, TLS, first byte), client-ready branded reports, retention of a year or more stated per plan, a raw export of check results, the vendor's incident history and post-mortems public, and an SLA with credits published.

10 — A record that holds up in an audit: SLA calculations with their method stated, incident records suitable for ISO 27001, NIS2 or DORA evidence, full history exportable in an open format, a self-hosted or open-source edition with feature parity stated, and the vendor's own availability over several years published.

Report an error

The E-Commerce Operations Manager

The reporting dashboard with average, P95 and P99 response times, per-phase timings, saved views, CSV export and an Analytics API, plus retention stated per plan (raw 7 to 180 days, aggregated up to 25 months), gives me the raw numbers for the agency conversation. But I found no scheduled email reports, no SLA with credits — the terms promise only commercially reasonable efforts to maintain availability — and nothing on the vendor's own status page, incident history or published probe addresses. 8 9 16 20 21

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where account data, alert contacts (names and phone numbers of the people on call), status page subscribers and check results are stored and processed, and who the subprocessors are (hosting, SMS and phone gateways, email delivery, support and payment tools). Independently sourced by the sovereignty pipeline. Probe locations outside Europe are part of what the product does and are not counted against it; where the data is stored and who processes it is. A self-hosted or open-source edition the customer runs on its own European servers counts as the customer's chain, whatever the vendor's seat.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.

3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.

5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (SMS and call gateways, email, support, payment) run through non-EU providers without a stated safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated — or a self-hosted edition documented that keeps every record on the customer's own servers.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor, or a self-hosted open-source edition with no call home, data export and deletion documented, and certifications published with their scope rather than implied.

Report an error

The E-Commerce Operations Manager

The security page states that all data is stored in AWS eu-west-1 (Ireland), a data processing addendum is incorporated into the terms, and Checkly holds SOC 2 Type 2 — reassuring for my subscribers' emails and my on-call staff's phone numbers. But I would contract with Checkly Inc. of Boston under New York law, the disaster-recovery fallback region is us-east-1, and the subprocessor chain runs through US providers such as Auth0, Stripe, Google, Segment and Anthropic with locations and safeguards largely unstated. 9 10 11

Pricing transparency

How this is scored

Whether a buyer can compute the real annual cost from public pages alone: price per tier by number of monitors, check interval and status pages, team seats and on-call responders, what SMS and phone alerts cost, which features (multi-step or browser checks, SSO, longer retention, private locations, white-label) cost extra, the free tier and its limits, overage handling, minimum term and VAT.

0 — No public prices at all; every customer is a sales call.

3 — A starting price or a free tier exists, but how cost scales with monitors, intervals, seats or alerts is unclear.

5 — Tiers are public with their monitor count, interval and main inclusions, but at least one commonly needed piece (SMS or call alerts, extra seats, extra status pages, SSO, longer retention) is unpriced or "on request".

8 — Every tier priced publicly with its scaling rule (monitors, interval, seats, responders, status pages), SMS and call costs stated, add-ons priced, overage handling stated, minimum term and VAT treatment stated.

10 — Complete price computability: annual cost derivable for a given number of monitors, interval, team size and alert volume, with every add-on, overage and support fee and the cancellation and data-return terms published.

Report an error

The E-Commerce Operations Manager

I can nearly compute the season's cost from the pricing page alone: Starter $24 per month or Team $64 per month billed annually, additional 25 monitors for $8, browser overages at $6.50 or $6.25 per 1k runs, status-page modules at $9 and $30 per month, subscriber overages billed automatically, and German invoices including VAT. The gaps: no price for seats above the plan's user count, nothing on what SMS or calls beyond the monthly quota cost, add-ons like traces priced only through sales, and Enterprise is quote-only. 8 9 17
