New Relic Synthetics
New Relic's synthetic checks bundled with full observability stack — generous free tier.
Free tier: 1 user, 100GB ingest/mo
What it does well
- Generous free tier includes 100GB of data ingest and full platform access.
- Integrates synthetic results directly with APM traces for deep-dive performance analysis.
- Provides a global network of test locations for simulating international user experiences.
- Supports scriptable browser tests using Selenium-based JavaScript for complex user journey simulation.
Where it falls short
- Not a standalone product; requires using the entire, complex New Relic One platform.
- Pricing is based on data ingest, which can be unpredictable and costly at scale.
- The user interface can be overwhelming for users only needing simple uptime checks.
- Fewer check types and integrations compared to some specialized synthetic monitoring competitors.
