Get notified when your device, website or service is down
Simple and reliable monitoring for websites, APIs, and servers. One free monitor forever.
Monitor Everything
Multiple monitoring types to cover your entire stack.
HTTP
Ensure the web server is functioning properly with simple and straightforward HTTP monitoring. Check status codes, response times, and full availability.
SSL
Be the first to know about any SSL certificate issues. Notifications are sent 30, 10 and 1 day before certificate expiration, so you'll have enough time to renew it.
Port
Monitor any port on your server — SSH, FTP, SMTP, databases and more. Make sure critical services behind specific ports are reachable.
Ping
Simple and reliable ICMP monitoring. Make sure your server or any device in the network is available and responding.
Keyword
Keyword-based monitoring checks presence or absence of a specific word or phrase on a webpage to detect content regressions and defacements.
Domain
Never lose your domain again. Monitor domain expiration date.
Why Choose App Checks
Experience peace of mind with our monitoring features designed for reliability and simplicity.
True independence
Most monitoring tools run on the same infrastructure you're monitoring. AppChecks doesn't. We operate externally, so you get alerts even when your cloud provider goes down.
No user paywalls
We don't charge per user. Add as many emails, or phone numbers as you want — alerts go to everyone who needs them, not just to the one who pays.
Beyond tech
AppChecks isn't just for developers. Marketers, managers, and business owners can easily track website uptime, landing pages, or price changes — no code required.
Deep visibility in one place
HTTP, SSL, keyword, port, ping, and domain — everything under one clean dashboard. No need to juggle different tools to understand what's happening.
Predictable simplicity
Forget tiered plans and complex "per-seat" billing. AppChecks keeps it simple — $2 per monitor, one free forever, nothing hidden.
Smarter alerting
Stay informed the way you want: Email, Telegram, Webhook, SMS, Call, or Pushover. Critical outages trigger calls, small issues go to chat — so you never overreact or miss what matters.
Built for modern workflows
Integrate effortlessly with your stack via Webhooks. AppChecks fits into how your team already works, not the other way around.
Designed to stay out of your way
No clutter, no setup hell. Add a monitor in two clicks and get on with your day. You'll only hear from AppChecks when something truly needs your attention.
