One screen for your whole fleet's health.

A single reliability score, a live health matrix per site, uptime and latency over time, and every incident in one place — so you spot trouble before it spreads.

  • Reliability score

    A weighted read on how healthy everything is right now.

  • Health matrix

    Reachability, latency and stability for each site, colour-coded.

  • SLA targets

    Set a target per site and see who is on track or breached.

Reliability matrix — reliability score, health matrix, SLA targets and incidents

The whole surface of a website — not just "is it up".

Eight kinds of check run on every site, grouped the way you actually think about them — so a green tick means healthy, not just reachable.

Availability
Uptime monitoring
Checks every 15 minutes with multi-layer verification, so one network blip never pages you.
Incidents
Contiguous downtime grouped into real incidents with duration and probable cause.
Maintenance windows
Schedule planned work so it never dings your SLA or wakes your team.
Certificates & content
SSL & domain expiry
Days remaining, issuer and registrar — with a heads-up long before anything lapses.
Content checks
Assert a page contains (or never contains) key text — catch "200 OK but broken".
Screenshots
A Wayback-style visual record: daily, on-demand and automatic error snapshots.
Performance & foresight
Response time
Latency tracked hour by hour, 30 days of history, and spike anomaly detection.
AI forecasting
72-hour predictions for uptime and response, with plain-language risk levels.

Synthetic monitoring

Is your login actually working — or just “up”?

A 200 OK doesn’t mean customers can sign in. Synthetic checks drive a real browser through the whole journey — log in, click through, add to cart — and page you the moment a step breaks, with a screenshot of exactly where.

  • Real user journeys

    Chain navigate, fill, click, wait and assert into a login or checkout flow. Start from a one-click template, then edit.

  • Fails exactly where it breaks

    If any step fails the site is marked down and we capture a screenshot at that step — password fields masked.

  • Credentials, handled

    Logins are encrypted at rest and referenced safely in any step. Auto-detect selectors straight from your own page.

Minimal load testing

See how your site holds up under a burst.

Not a full stress-testing rig — a fast, bounded burst of virtual users (up to 100, for up to a minute) you fire at any site right from its dashboard. Enough to spot-check before a launch or a campaign, with a plain-English verdict.

  • Bounded and safe

    Hard caps — up to 100 virtual users for up to 60 seconds — with automatic abort the moment the target starts failing. A smoke test, not a siege.

  • The numbers that matter

    Requests per second, p50–p99 latency, time-to-first-byte and error rate — charted second by second.

  • A clear pass or fail

    Set a p95 and error-budget target and get a verdict, plus a plain-language read on what slowed down and why.

Monitor what the cloud can't reach.

Internal dashboards, staging behind a VPN, a box on the office LAN, even localhost — download a tiny agent that checks them from your own machine and network, and pings your desktop the instant one drops.

  • Runs on your network

    Reaches firewalled and internal sites a cloud checker never could.

  • Native desktop alerts

    A real Windows / macOS / Linux notification the moment a site goes down.

  • Everything still syncs

    Results flow to your dashboard and fire email + Slack / Discord / Teams as normal.

1

Add your sites

Paste a URL — or bulk-import a whole list. No agents, no DNS changes, nothing to install.

2

We watch, 24/7

Uptime, SSL, domain and response time, checked every 15 minutes from the cloud.

3

You get alerted

The instant something breaks, the right people hear about it — with the reason and a timestamp.

Public status pages

Show customers you're on it.

Share a clean status page with live components, a 90-day uptime calendar and a real incident timeline. Visitors can subscribe to get emailed the moment something changes.

Personal & team workspaces

Solo, or a whole team.

Keep your own sites in a personal workspace, or create teams with Admin, Editor and Member roles. Switch between them from the top bar — everyone who should know, knows.

Questions,
answered.

Everything worth knowing before you start.

Every 15 minutes automatically. You can also run a manual check any time from the dashboard.

You get an instant alert — reason, response code and timestamp — by email and any connected integrations, plus an in-app activity alert.

Yes, as many as you like. Bulk import adds a whole list at once from a file or a paste.

Yes — WebChecky tracks certificate and domain expiry and warns you well before either lapses.

Yes. Publish a public status page with components, an uptime calendar, an incident timeline and email subscriptions.

Yes. Create teams with role-based access and a shared workspace, and switch contexts from the top bar.

Yes — WebChecky includes a minimal, bounded load test you run on demand from any site's dashboard. Pick the virtual users (up to 100) and duration (up to 60s), set optional latency and error targets, and get a pass/fail verdict with per-second charts. It's a spot-check, not a full stress-testing suite — hard caps and auto-abort keep it safe.

Yes. Synthetic monitoring drives a real browser through a whole journey — log in, click through, add to cart — and asserts what should be on the page. Start from a one-click login template, store credentials encrypted, and auto-detect selectors from your own page. If any step fails, the site is marked down with a screenshot captured at the exact failing step.

Nothing — WebChecky is fully cloud-based and runs from your browser.

Yes — a RESTful API with key auth to fetch status and uptime, schedule maintenance and automate checks.
