The whole surface of a website — not just "is it up".
WebChecky combines 24/7 multi-region uptime, synthetic browser journeys, and deep diagnostics into a unified platform. Inspect, benchmark, and alert on every critical layer of your infrastructure.
DNS Lookup & Change Monitoring
Resolve A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, PTR, SRV and DNSSEC. Automatically detects missing records, SPF lookup exhaustion (>10), and alerts your team the second an IP or nameserver changes.
Email Security & Deliverability
Deep SPF syntax and include-chain validation, automatic DKIM provider detection (Google Workspace, M365, SendGrid, Mailgun, Amazon SES), DMARC policy enforcement, and reputation monitoring across global DNSBL blacklists.
Security Center & Defense Headers
Comprehensive HTTPS and SSL certificate verification, redirect chain tracking, and automated scoring of critical defense headers: CSP, HSTS, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
OWASP Top 10 Vulnerability Checks
Audit insecure cookies (missing Secure, HttpOnly, SameSite flags), server information disclosure, unsafe CORS policies, directory listings, exposed configuration files, publicly accessible .git repositories, and outdated libraries.
Attack Surface & Exposure Monitor
Proactively probes target domains for exposed administrative portals (/admin, /wp-admin, /login), XML-RPC APIs, debug traces, source maps (.js.map), backup archives, and leaked staging environments.
Technical & On-Page SEO Audit
Instant SEO health analyzer verifying titles, meta descriptions, heading hierarchy (H1/H2), canonical URLs, robots.txt, sitemap.xml, Open Graph, Twitter cards, Schema.org JSON-LD, broken links, and image alt tags.
Technology Stack Detection & Evolution
Multi-vector fingerprinting for CMS (WordPress, Shopify, Drupal), web frameworks (Next.js, React, Laravel, Vue, Django), servers (Nginx, Apache, Cloudflare), cloud hosting, and analytics scripts with change alerts.
Cron Job & Heartbeat Monitoring
Give your background workers, database backup tasks, and scheduled jobs a ping URL (webchecky.com/heartbeat/abc123). If the heartbeat doesn't arrive on schedule, WebChecky alerts your team immediately.
White-Label Agency PDF Reports
Generate multi-page executive client audit PDFs with your agency name, custom logo, brand color palettes, client name, custom notes, and verified WebChecky footer certifications.
Playwright Synthetic User Journeys
Drive real headless browser interactions through checkouts, logins, and multi-step forms. When a step breaks, get alerted with a full-page screenshot of the exact failure state with masked credentials.
Core Web Vitals & Performance
Real-time measurements for LCP, CLS, TTFB, FCP, page weight, request counts, and 30-day response latency charts with AI-powered 72-hour outage risk forecasting.
Localhost & Private Network Agent
Download our lightweight single-binary webchecky-agent for Windows, macOS, and Linux to monitor internal dashboards behind VPNs, office LANs, and localhost with native desktop alerts.
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.

Errors
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.

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

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.
