Know the second your
website goes down.

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.
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.

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.

Add your sites
Paste a URL — or bulk-import a whole list. No agents, no DNS changes, nothing to install.
We watch, 24/7
Uptime, SSL, domain and response time, checked every 15 minutes from the cloud.
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.
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.
