HTTP, SSL, DNS, and TCP checks with a full latency breakdown — DNS, TLS, TCP connect, and total. Schedule them, define checks as YAML, suppress alerts during maintenance, and watch uptime roll up automatically.
Run HTTP, SSL, DNS, and TCP checks on the frequency you choose. Catch outages, DNS failures, and expiring certs before a customer files a ticket.
Every run breaks latency into DNS resolution, TLS handshake, TCP connect, and total response. When a check slows down, you already know which layer to blame.
Define and version checks as YAML so they live in your repo, not a UI. Declare maintenance windows to suppress alerts during planned deploys — no false pages.
One platform, tailored to how your team actually works.
Detect outages from scheduled probes before users report them.
Multi-step checks watch login and checkout flows 24/7.
Hourly uptime rollups turn raw checks into reportable uptime numbers.
Every check run lands in the same ClickHouse backend as your logs, metrics, and traces, with materialized views rolling uptime up hourly. That means synthetic failures correlate directly with the server-side traces and logs from the same window — outside-in and inside-out views of the same incident.
