The complete monitoring platform
Uptime, SEO and security monitoring under a single roof. Nine monitor types, insight modules, a ten-point Security Shield and eight alert channels, watching your sites around the clock from multiple locations.
Free plan needs no card. Paid plans start with a 14-day trial.
Live HTTP request from our network - the same check PulseStack runs as often as every 30 seconds.
One dashboard for websites, APIs, ports, jobs and infrastructure, plus the SSL certificate, DNS record and domain expiry monitors below. Mix and match the checks that match how your service actually fails.
Watch any website or web app for status codes, response time and redirect chains. Add custom request headers on HTTP and API checks.
Confirm a phrase is present, or flag when it appears. Catch defacements, broken templates and empty renders the moment they happen.
Lightweight, timed TCP connection checks to a host and port (port 80 by default) for servers and network services.
Verify a specific TCP port is open and accepting connections, from SMTP and databases to game and app servers.
Poll JSON endpoints with custom headers, a request body and the status code you expect, so an unexpected status code fails the check.
Flip monitoring inside out for cron jobs and background workers. If the expected ping never arrives, PulseStack alerts you.
Uptime tells you a site is reachable. SSL certificate, DNS record and domain expiry monitors warn you about the quieter problems that take sites down weeks from now, and website monitors show the same details in the dashboard sidebar.
Days to expiry and issuer, with an alert 7 days before expiry by default, or a lead time you set, so a lapsed certificate never greets your visitors with a browser warning.
Watch an A, AAAA, MX, CNAME, TXT or NS record and get an alert when it no longer contains the value you expect.
Registration expiry from public RDAP data, with an alert 7 days before the domain lapses by default, keeping renewal deadlines in plain sight.
A silent SEO regression costs traffic long before anyone notices. PulseStack runs eight on-page checks on a schedule so a stray noindex or a missing canonical is caught the day it ships, not the month your rankings drop.
Security Shield checks your headers, cookies, TLS setup, open ports, blacklists, DNS security and more, then rolls the findings into a single letter grade from A to F. Most tests read public information; the open-ports test connects to common ports and subdomain discovery looks up likely subdomains. Security Shield is a separate subscription, with a free tier that audits security headers on one site.
Grades run A through F across all ten tests
Route incidents to wherever your team already lives. Every channel fires on failure and on recovery, and every failure is double-checked first so a single blip never wakes anyone.
SMS alerts are included on the Team and Enterprise plans. Zapier and Google Chat connect through the webhook channel. How each integration works
Website, keyword, API, ping and port monitors are checked from three locations, London, New York and Sydney, so a regional outage or a bad route is caught for what it is rather than mistaken for a full outage. A monitor only goes down when at least two locations fail, and response times are charted for each location.
Turn an incident into a single link. Publish a live status page with your logo and colours on any plan, showing each monitor's current status and daily history for the last 30 days.
Last 40 checks
Every check records how long the response took, charted separately for London, New York and Sydney over the last 30 days, so a slowdown that builds over a week, or only affects one region, is easy to spot.
Every failure and recovery is logged with timing, so you have an honest record to review after the fact. Spot the pattern behind the repeat offenders instead of relying on memory.
Install a lightweight agent and PulseStack reports CPU, memory and disk usage next to your uptime data. When a response goes slow, you can see the resource pressure behind it rather than guessing.

Nine: HTTP(S), Keyword, TCP Ping, Port, API, Heartbeat, SSL certificate, DNS record and domain expiry. The Free plan covers HTTP(S) checks, and every paid plan unlocks all nine types.
From the Starter plan upward, website monitors show SSL certificate, DNS and domain details in the dashboard sidebar, and you can add SSL certificate, DNS record and domain expiry monitors that alert you before a certificate or domain lapses.
Ten light-touch tests: security headers, TLS configuration, cookie security, mixed content, open ports, blacklist check, technology fingerprinting, domain WHOIS, DNS security and subdomain discovery. Results are rolled into a straightforward letter grade from A to F so you know where you stand at a glance. Security Shield is a separate subscription: a free tier audits security headers on one site, and paid tiers cost £29, £69 or £129 a month for 5, 15 or 50 sites.
Eight native channels: Email, SMS, Slack, Microsoft Teams, Discord, PagerDuty, Telegram and Webhooks. Alerts fire on both failure and recovery, and every failure is double-checked first to cut noise. SMS alerts are included on the Team and Enterprise plans.
Free plans check every 300 seconds and Starter every 60 seconds. Pro, Team and Enterprise bring that down to 30 seconds. Checks run from London, New York and Sydney.
From the Team plan upward you can install a lightweight agent that reports CPU, memory and disk usage, so you can correlate a slow response with the resource pressure behind it.
Yes. Every plan includes at least one public status page with your logo and colours (the Free plan includes one). Pro and above can remove the PulseStack branding, and Team and Enterprise can use their own domain.
No. The Free plan needs no card at all, and every paid plan starts with a 14-day free trial that needs no card either. Annual billing saves 20 percent against monthly.
Uptime, SEO and security, watched from multiple locations and routed to the channels you already use. Start on the free plan with no card, or try a one-off check with our free tools first.
