Status changes propagate via WebSocket the moment they happen. No manual refreshing, no stale data — your monitor state is always current.
15-minute cooldown prevents alert spam. You get notified once on downtime, once on recovery.
Pass auth tokens, API keys, or any request header. Supports up to 50 headers per monitor.
Every check is logged with status code, response time, and error context. Free plan retains 7 days; Pro extends to 30.
