New Relic Synthetics review: a real free tier with a hard edge

New Relic gives away more than almost anyone: 100GB of data ingest every month and 500 synthetic checks, free, permanently. It is a genuine offer rather than a trial. It also has the sharpest failure mode in this comparison — go over 100GB and data ingestion stops entirely and you lose platform access until you upgrade or the month rolls over.

Is New Relic Synthetics worth it?

As part of a New Relic estate, yes. As a standalone uptime monitor, the free 500 checks a month works out at roughly one check every 90 minutes for a single URL, which is not monitoring in any useful sense. The free tier is generous for observability and thin for synthetics specifically, and the 100GB cliff means the free plan can take your entire platform offline at the worst possible moment.

Generous platform, thin on checks Our assessment, written by the team behind a competing product — read it as an informed opinion, not a neutral audit. Every factual claim is checked against New Relic Synthetics's own public pricing and documentation at the time of writing.
Overview

What New Relic Synthetics is

New Relic Synthetics is the synthetic monitoring component of the wider New Relic observability platform. It runs scripted and simple checks against endpoints and browser journeys, reporting alongside APM, infrastructure and log data.

Pricing works on two axes at once. Data ingest is measured in gigabytes — 100GB free each month, then $0.40 per GB on Original Data or $0.60 on Data Plus. Synthetic checks are counted per execution, with 500 a month on the free edition, 10,000 included on Standard, and overage at $0.005 per check.

The detail worth reading twice: exceed 100GB in a calendar month and ingestion stops and platform access is lost until you upgrade or the next month begins. A free monitoring tool that can switch itself off during a busy month is a different risk profile from a free tool that simply stops adding monitors.

Capabilities

What New Relic Synthetics does well

Strong platform economics, if synthetics are part of something bigger.

100GB free ingest every month

Permanently, not as a trial. For a small estate this covers a lot of real observability at no cost.

Synthetics inside full observability

Checks sit alongside APM, infrastructure, logs and browser monitoring, so a failure has context immediately.

Scripted browser checks

Multi-step journeys as well as simple availability, from managed locations.

Predictable check overage

$0.005 per check beyond the allowance, which is cheap per unit and easy to reason about.

10,000 checks on Standard

Enough for genuine monitoring once you are on a paid edition.

Alerting and dashboards included

The platform's alerting applies to synthetics without separate tooling.

Cost

What New Relic Synthetics costs

Two meters: gigabytes ingested and checks executed.

Item Free edition Paid Notes
Data ingest 100GB/month $0.40/GB $0.60/GB on Data Plus
Synthetic checks 500/month 10,000 on Standard Overage $0.005 per check
Exceeding 100GB free Ingest stops Platform access lost until upgrade or next month

Monitoring vendors change plan limits and prices frequently and without announcement. Every figure here carries a "verify on their site" caveat and you should take it seriously before making a decision on cost.

The balance

Where it is strong, and where it is not

What works

  • 100GB of monthly ingest free, permanently, which is unusually generous.
  • Synthetics correlated with APM, infrastructure and log data.
  • Scripted browser journeys as well as simple checks.
  • Check overage at $0.005 is cheap and easy to forecast.
  • A single platform rather than a monitoring tool bolted alongside one.

What to watch out for

  • Exceeding 100GB stops ingest and cuts platform access entirely.
  • 500 free checks a month is far too few for real uptime monitoring.
  • Two separate meters make cost modelling harder than a plan.
  • Considerable platform complexity if synthetics is all you want.
  • Certificate and domain expiry are not first-class monitor types.
Fit

Who New Relic Synthetics is for

Choose it if

  • Teams already using New Relic for APM or infrastructure.
  • Organisations wanting observability and synthetics from one vendor.
  • Engineering teams who will use the wider platform properly.
  • Anyone whose data volume sits comfortably under 100GB a month.

Look elsewhere if

  • Anyone who only wants uptime checks, where 500 a month is not enough.
  • Teams who cannot risk losing platform access on a data spike.
  • Buyers wanting one simple predictable monthly figure.
  • People whose priority is certificate and domain renewals.
Disclosure

Where MonitoringDaddy fits

New Relic is an observability platform that includes synthetics; we are a monitoring service. If you want APM traces, infrastructure metrics and logs in one place, we do not compete and should not be considered.

For checking things on a schedule, the comparison is stark. Their free tier allows 500 checks a month, which spread across a single URL is roughly one check every 90 minutes. Our $5 plan checks 25 monitors every five minutes, which is about 216,000 checks a month, and nothing is counted.

The 100GB cliff is the difference in risk worth naming. Their free plan can stop ingesting and lock you out of the platform during a busy month. Ours does not have a meter that can do that — if you are inside your monitor count, the checks run.

The honest split: observability across a real engineering estate — theirs, and the free ingest allowance is genuinely good. Knowing that sites, certificates, domains and pages are fine, at a frequency that counts as monitoring — ours.

FAQ

New Relic Synthetics review: your questions answered

Is New Relic Synthetics free?

The free edition includes 100GB of data ingest a month and 500 synthetic checks. Both are permanent rather than a trial, but 500 checks is a small allowance for uptime monitoring specifically.

What happens if I exceed 100GB?

Data ingestion stops and you lose platform access until you either upgrade to a paid edition or the next calendar month begins. This is the most important thing to understand about the free tier.

How many checks do I actually need?

One URL checked every five minutes is about 8,640 checks a month. The free allowance of 500 covers roughly one check every 90 minutes for a single URL, so it is better read as a way to try synthetics than to rely on them.

What does check overage cost?

$0.005 per check beyond the allowance on paid editions. Standard includes 10,000 checks a month.

What does data beyond the free allowance cost?

$0.40 per GB on the Original Data option or $0.60 per GB on Data Plus.

Does it monitor SSL certificates?

Not as a first-class monitor type with its own expiry alerting window. Certificate renewals are better served by a tool that treats them as their own concern.

Is it worth using only for synthetics?

No. The platform is the product; synthetics alone does not justify the complexity or the allowance limits.

How does it compare with MonitoringDaddy?

They offer full observability and we do not. Their free tier allows 500 checks a month; our $5 plan runs roughly 216,000 and counts none of them, and includes certificates, domains, page changes and heartbeats.
