status monitoring

Know when your website, server, audio, or video stream goes down.

UptimeBuddy watches HTTPS endpoints, DNS records, SSL certificates, page keywords, TCP ports, IP hosts, audio streams, and video feeds on a schedule you choose. With your self-hosted agent, it can also detect silence, black screens, and frozen frames — then email or text you when something breaks.

HTTPS domain checks

Certificate-aware GET requests with status codes and response times on every run.

DNS record checks

Resolve A, AAAA, CNAME, MX, TXT, and NS records, and alert when they change or go missing.

IP host checks

Reach any IP address on a chosen port and confirm the host is answering.

SSL certificate checks

Track certificate expiry and issuer, and get warned days before it lapses — included on every plan.

Keyword & content checks

Watch a page for a word or phrase and alert when it disappears — or when an error message appears.

TCP port checks

Open a connection to any port — SMTP, SSH, databases, game servers — and alert when it stops answering.

Audio stream checks

Monitor Icecast, Shoutcast, and HLS audio streams for liveness — and detect silence with the self-hosted agent's ffmpeg probe.

Video stream checks

Watch HLS playlists and direct feeds for reachability. The self-hosted agent checks the picture for black screens and frozen frames.

Your own intervals

From every minute to once a day, per monitor — pause any of them anytime.

Email alerts

Get notified the moment a monitor flips down, and again when it recovers.

SMS alerts

Optional text-message downtime alerts straight to your phone, powered by GatewayAPI.
