FAQ

What is VigilAPI?

VigilAPI is an API monitoring tool that watches your endpoints on a schedule, detects downtime and response changes, and sends alerts to Slack.

Who is VigilAPI for?

Developers, startups, and teams who rely on third-party or own APIs and want simple uptime monitoring without setting up their own infrastructure.

Is there a free API monitoring plan?

Yes. The free plan includes 3 monitored APIs, daily checks, Slack webhook alerts, and 7-day history — no credit card required.

How is VigilAPI different from other API monitors?

VigilAPI focuses on what matters: scheduled checks, payload change detection, false-alert suppression, and Slack notifications — without complexity.

Do I need Slack to use VigilAPI?

Alerts are delivered via Slack incoming webhooks. Connect a webhook once and get notified when an API goes down or its response changes.

Can I monitor my own APIs with VigilAPI?

Yes. Add any public HTTP or HTTPS endpoint — your backend, a partner API, or a SaaS service — and VigilAPI will track its health for you.
