Is your site running smoothly,
Or are you just monitoring uptime?

Vigilant is the all-in-one open-source web monitoring platform.
Uptime. Flows. SSL. Broken Links. Certificates. CVE's.
Everything a website needs in one platform.

Tired of duct-taping your
web monitoring stack together?

You’ve probably got a tool for uptime. Maybe another for SSL. You run Lighthouse audits manually when you remember. And if something goes wrong with DNS or a critical CVE lands? You're lucky if you find out in time.

Most website owners don’t really know if their site is functioning optimally — because real monitoring is fragmented, manual, or just missing.

You’re not alone. Everyone starts with “just enough” monitoring. Until that one incident shows you what got missed. An essential flow on your website broke. The certificate that expired. The DNS record that broke. The performance regression no one saw coming.

It doesn't have to be this way.

Vigilant brings everything into one place
so nothing slips through the cracks.

Vigilant handles the basics automatically,
with sensible defaults that work out of the box.

It's always DNS.

Browsers throw up scary warnings. APIs stop talking to each other. Your users bounce. And unless you’re actively tracking expiration dates, it’s easy to miss.

Vigilant will notify you when your certificates are about to expire.

Always know when a certificate is about to expire.

Broken links are a common issue that can frustrate users and lead to lost sales. They can occur for various reasons, such as changes in website structure, outdated content, or incorrect URLs. Vigilant helps you identify and fix these issues quickly, ensuring a seamless user experience.

Get notified on the right channel.

Vigilant supports mutliple notification channels to ensure you receive alerts in the way that suits you best. Whether it's email, Slack, or Discord, you can configure your preferred channels to stay informed about critical events and issues.

Vigilant's notification system is customizable, allowing you to set up different channels for different types of alerts or different channels for different websites. This flexibility ensures that you can manage your notifications effectively and efficiently.

When things break the right people need to know. With Vigilant you can make sure that this happens.

For any serious website,

Monitoring should be default.

Start Monitoring Everything
Lighthouse and latency Monitoring.

Prevent angry customers when your site slows down.

Vigilant will track your website's performance using Lighthouse and latency monitoring.
Get notified when your performance scores drop below a certain threshold, or when your latency increases.
This way you can ensure that your website is always performing at its best, and your customers are getting the best experience possible.

Catch website issues before they cost you customers.

Why monitor your website?

Your website should always be available and performing at it's best. If it’s not, you risk losing visitors and customers.

Some issues are easy to notice, like a full outage—but others, like slowdowns, go unnoticed until they start costing you revenue. A single change can impact performance without you realizing it.

Vigilant monitors your site 24/7, infrastructure changes, performance issues and broken links, so you can fix them before they affect your customers.
