Uptime, SEO and security in one platform
Stop stitching together three separate tools. PulseStack watches your sites for outages, crawl problems and security gaps, then alerts you the moment something changes and again when it recovers.
Free plan, no card. 14-day trial on every paid plan.
Check your site now
Live HTTP request from our network - the same check PulseStack runs as often as every 30 seconds.
One platform, not three tools
Each of these usually means another dashboard and another login. PulseStack folds all three into a single account.
Nine monitor types watch your endpoints, APIs, ports, background jobs, certificates and domains, with uptime checks confirmed from multiple locations, then alert on failure and on recovery.
Eight crawl checks watch how search engines actually see your site, from robots.txt and sitemaps to canonicals and bot-versus-browser rendering.
The Security Shield runs ten light-touch tests against each site and rolls them into a single A to F grade you can track over time.
Nine monitor types
From a public web page to a background cron job, mix and match the monitors that match your stack.
Status codes, response time and content from any public URL.
Confirm expected text is present, or alert when it disappears.
Reachability checks for any host that answers on TCP.
Watch a specific service port for open or closed state.
Send your method, headers and body, and check for the expected status code.
Cron and background jobs check in, or you get alerted.
Get alerted before a certificate expires, or as soon as it turns invalid.
Watch a record on your domain and get alerted when the expected value disappears.
Get alerted when a domain registration is close to expiring.
How it works
Paste a URL, host or endpoint. Pick the monitor type and interval that fits the plan you are on.
Layer on SEO crawl checks and insight modules where your plan includes them, plus the Security Shield, which is a separate subscription.
Connect any of eight channels. Failed checks are re-tested and confirmed from at least two locations to keep the noise down.
Turn on a public status page, schedule maintenance windows and review 30 days of check history.
Insight modules
Available on Starter and up, insight modules watch the slow-moving details that cause sudden outages when they lapse.
Track expiry dates and validity so a lapsed certificate never surprises you.
Check your records hold the values you expect, and get alerted when they do not.
Monitor registration windows and see renewal dates well ahead of time.
Security Shield
The Security Shield inspects each site for common exposure signals and rolls them into a single A to F grade, re-checked on every cycle so you can watch the trend.
Overall grade
Grades run from A through F and update on every scan.
Light-touch by design: most tests read publicly available information, while the open-ports test connects to common ports.
Eight native alert channels
Every channel fires on failure and again on recovery, and failures are confirmed from at least two locations so you only hear about real incidents.
SMS alerts are included on Team and Enterprise plans.
Confirm a problem from more than one place before anyone gets paged, so a single bad route does not trigger a false alarm.
Publish a hosted status page on any plan and keep customers informed without a single manual update.
Schedule maintenance windows so planned work never pages you, and keep 30 days of check history for every monitor.
Free tools
The checks PulseStack™ runs on a schedule are also free one-off tools. Each one sends a real request from our UK server when you press the button, and nothing is saved.

PulseStack runs eight crawl checks that look at how search engines see your site, including robots.txt, sitemaps, canonical tags, redirect chains and how a bot renders a page compared with a browser.
It runs ten light-touch security tests against a site and rolls them into a single A to F grade, re-checked on every cycle so you can track the trend. It is a separate subscription, with a free tier that audits security headers for one site.
Through any of eight native channels: Email, SMS, Slack, Microsoft Teams, Discord, PagerDuty, Telegram and Webhooks. Alerts fire on failure and on recovery, and a monitor is only marked down when at least two of the three check locations fail, to cut noise. SMS alerts are included on Team and Enterprise.
The Free plan checks every five minutes. Starter checks every 60 seconds, and Pro, Team and Enterprise check as fast as every 30 seconds.
Yes. Every plan can publish a public status page, and you can schedule maintenance windows and review 30 days of check history.
