// PLATFORM KEY CAPABILITIES

Designed for high-throughput monitors

Explore all 6 features

Uptime & assert conditions

Ping HTTP, REST, GraphQL, or gRPC. Create complex JSON assertions on the header payloads, status values, and custom returned keys.

Configure uptime

Response time tracking

See precise latency percentiles (p50, p90, p99) split across regions in real time to locate slow server connections instantly.

Check benchmarks

Slack & Email Incident Alerts

Hook up your team with zero latency. Deliver instant message notifications directly into developer Slack channels or email list routing.
