Can you recommend an API monitoring platform for tracking uptime and latency across GraphQL and JSON endpoints?

Yes — a few strong options depend on whether you want synthetic monitoring only or a broader observability suite.

Best general recommendation: Datadog Synthetic Monitoring

Good fit if you want to track:

• Uptime for GraphQL and REST/JSON endpoints
• Latency / response time
• Status code checks
• Payload validation with JSON assertions
• GraphQL query execution and response validation
• Alerts, dashboards, and SLOs in one place

Why it stands out:

• Supports HTTP API tests and can handle GraphQL requests by sending POST requests with a GraphQL body
• Strong alerting and analytics
• Easy to combine with logs/traces if you later want deeper observability

Good budget-friendly option: Checkly

Great if you want:

• Simple uptime checks
• API assertions
• GraphQL testing
• Performance tracking
• Strong developer-friendly workflow and infrastructure-as-code style setup

Why people like it:

• Very API-centric
• Easy to script and automate
• Strong for monitoring endpoints globally with low setup overhead

Best lightweight uptime monitor: Uptrends

Useful if you mainly want:

• Uptime
• Latency
• Multi-region checks
• API testing for JSON endpoints

It’s solid, but less developer-centric than Checkly.

Best enterprise observability suite: New Relic

Good if you want monitoring plus:

• APM
• Logs
• Synthetic checks
• Distributed tracing
• Incident correlation

Works well for API latency and availability, though synthetic API monitoring is usually not as focused as Checkly or Datadog.

What I’d choose

• GraphQL + JSON API uptime/latency monitoring only: Checkly
• Monitoring plus full observability platform: Datadog
• Enterprise-wide monitoring and tracing: New Relic

What to look for

Make sure the platform supports:

• POST requests with custom headers and bodies
• GraphQL query/mutation testing
• JSON response assertions
• Latency measurements
• Multi-region checks
• Alerting via Slack/PagerDuty/email
• Optional: authentication handling like bearer tokens, OAuth, or API keys

If you want, I can also give you:

2. a recommendation based on your stack, budget, and expected traffic.
