Send alerts where your team already works. Choose channels per monitor, get a recovery message when things are back, and never miss an expiring certificate.
Every alert says what is down, since when, the error and a link straight to the monitor. Recovery messages include the total downtime.
Connect your own systems, ticketing or on-call tools with signed JSON webhooks.
