Website monitoring & uptime trackingSimple for beginners. Powerful for experts.
WWT watches your websites around the clock: uptime, certificates, domain renewals and email security. Alerts land where you want them, written so both a business owner and an engineer know what just happened and what to do next.
Made by people who've been on the other end of the alert.
WWT was built by people who have spent thirty years running production systems: renewing certificates that 'just expired', recovering domains that quietly lapsed, answering the 2am phone call. At some point you start building the tool you always wished had been watching.
If you're not technical, this is the friend who quietly checks every morning whether your company website still answers, whether the domain is still in your name, whether the certificate won't trip a browser warning next week. You don't need to know what TLSv1.0 is - we'll only tell you in plain language when it actually matters.
If you are technical, this is the same friend with all the knobs visible: per-site failure thresholds, parallel checks, an audit log of every alert, RDAP for domain registrars, SPF/DMARC drift detection and nine notification channels, each in its own language. Built by people who have done the on-call rotation themselves.
A monitoring tool should not be a luxury. WWT has a free plan that covers real needs, and the paid plans - for more domains or one-minute checks - are priced to be fair. Whether you run one company site or a hundred client domains, you only start paying if you outgrow free.
- the WWT crew
Meet the people behind WWT
Built for the whole team.
Whether you look after a single company site or hundreds of client domains, you set WWT up once and forget the XLS files and the text files. Everything in one place.
You hear about problems before your customers do.
WWT keeps track of domain renewals, certificate expiry dates and the availability of every site your business depends on. Adding a domain takes about a minute; after that you simply get a clear message whenever something needs your attention.
- Domain registration expiry alerts on a five-step schedule (30, 14, 7, 3, 1 day)
- SSL certificate expiry alerts on the same schedule
- Notifications written in clear language - no log dumps, no jargon
- CSV bulk import to onboard an entire portfolio in one upload
All the controls you actually need.
Per-site failure thresholds, parallel workers, minute-precise recovery detection and an audit log of every alert. SPF, DMARC, DKIM and TLS versions are checked daily, record by record, so a quiet change gets caught before it grows into an incident.
- Per-site failure-count threshold filters out flapping checks
- Up to 15 parallel workers - capacity grows with your portfolio
- Email, Slack, Teams, Discord, Mattermost, Telegram, PagerDuty, Pushover, Webhook - independently routable per channel, each in its own language
- Audit log: every alert, every suppression, every override
Everything in one place. One clear dashboard.
Uptime, performance, certificates, domain registration and email security in a single dashboard - instead of five separate services.
Uptime monitoring
Per-minute HTTP checks with parallel workers. Configurable per-site interval and timeout.
Multi-region verification
When your site looks down, we re-check it from independent regions in Europe and North America before alerting you. A network blip near our servers stays quiet - only a real outage gets through.
Performance tracking
Response time logged on every check. Charts from one hour to a year.
TLS version reporting
Daily report of which TLS protocol versions your server actually negotiates.
Domain expiry (RDAP)
Live registrar lookup with a manual override for unsupported TLDs.
Email alerts
Plain-English notifications you can hand to a non-technical recipient.
Team collaboration
Multiple owners and members per organization, multi-org switching, role-based access.
Certificate expiry
Days remaining on the X.509 cert, with notifications at 30 / 14 / 7 / 3 / 1 days.
HTTP status filtering
Choose per-site which response classes count as success: 2xx, 3xx, 4xx, 5xx.
Multi-channel alerts
Email, Slack, Teams, Discord, Mattermost, Telegram, PagerDuty, Pushover and Webhook - every channel has a Test button and its own language setting.
SPF / DMARC / DKIM
Daily email-security record checks with the parsed record on display.
Audit log
Every notification, suppression, settings change and override is recorded.
CSV import & export
Bulk import websites with a 9-column CSV. Export the full list at any time.
Data export
Export everything WWT knows about you, at any time - in a single click.
Two-factor authentication
Protect your account with an authenticator app, a hardware security key or a passkey - use one method or combine them.

Real screenshots from the live application.
Every check, on one timeline.
Open a website to see uptime, response time, TLS version, certificate expiry, domain registration and recent checks - with chart ranges from one hour to a year.


TLS, cert, registrar, SPF, DMARC.
Every security signal that matters, in one panel - with the underlying record on display so you can verify what was actually checked.
The right person, the right channel.
Add as many channels as you need - Email, Slack, Teams, Discord, Mattermost, Telegram, PagerDuty, Pushover or your own webhook - and decide which channel gets which kind of alert. Every channel has a Test button and its own language setting, so a Polish-speaking team and an English-speaking client can follow the same site, each in their own language.


Hundreds of domains - one upload.
You don't have to add domains one at a time. Upload a single CSV with up to 100 rows and every site arrives with the right interval, threshold and check settings. Useful when you migrate from another tool or take over a whole portfolio.


A report you can hand to anyone.
A one-click summary of uptime, response time percentiles, incidents and the current security posture - formatted so it reads well on screen, in print or as a PDF.
New domains start with your defaults.
Set the default check interval, timeout, failure threshold, accepted HTTP codes and daily checks once, at the organization level. Every new domain starts from that template, and existing sites are never changed behind your back.


Override anything, on any single domain.
Some sites need their own rules: a slow backend that wants a longer timeout, a production site you check every minute, a staging URL that returns 4xx on purpose. Open the site's settings, change what needs changing and leave the rest on the team default.
The stat cards double as filters.
Click the uptime card on the dashboard to see only the sites below 100% in the last week, or the incidents card for the ones that actually went down. Together with search and column sorting, you get to the right site in a couple of clicks.


2FA your way: app, hardware key or passkey.
Turn on two-factor login with a code from any authenticator app, and add hardware security keys or passkeys on top - YubiKey, Touch ID, Windows Hello. With both set up, either method signs you in, and recovery codes cover a lost phone.

More eyes on your sites: we are adding Asia and Oceania
Until now we watched your sites from Europe and the US. We are expanding the network with two new vantage points: Singapore and Sydney. Why does it matter? The more places we check from, the easier it is to tell a real outage from one flaky connection hiccuping - and the better we see how your site behaves for someone in Asia or Australia, not just around the corner. The new nodes are being set up and will join the rest shortly.

Message us right from the app - and keep every reply in one place
We added a support inbox. Got a question, or something not working? Write to us without leaving WWT, and you'll see the whole conversation - your messages and our replies - in one place, with the status of your request. When we reply or the status changes, we email you so nothing slips by. No digging through your mailbox, no waiting in the dark - just quick, direct contact.

Leave or delete - always your choice
Staying should be a choice, not a trap. You can now leave any organization you're in, or delete your account entirely, straight from Settings > Profile - one click, no email to support, no waiting. Sole owner of an organization? Deleting your account clears it and its data too, after a clear confirmation. And your history stays intact for the teams you leave (without your personal details). It's your data and your call - in and out should both be simple.
