Quick verdict

Don't have time for 5,000 words? Here's the argument in three bullets:

• Pick Datadog if you want a broad observability-and-security platform — 1,000+ integrations, tightly connected alert-to-telemetry workflows, Cloud SIEM, and a generally available AI incident investigator in Bits AI SRE. Accept that the bill grows with every product you switch on, and that cost predictability depends on governing the enabled product meters.
• Pick New Relic if cost transparency and a low-friction start matter more: no per-host charges, a genuinely useful free tier (100 GB/month ingest + one full-platform user, no credit card), and first-class OpenTelemetry ingestion under its normal data and compute meters. Accept that full-platform seats at $349/user/month become the bottleneck as your engineering headcount grows.
• On cost, there is no universal winner. Host, data, user/compute, and optional-product meters interact. Section 3 gives reproducible component subtotals and identifies the missing inputs required for a complete comparison.

Both are Leaders in the 2025 Gartner Magic Quadrant for Observability Platforms — Datadog for the fifth consecutive year, New Relic for the thirteenth. You're not choosing between good and bad. You're choosing between two different ideas of how an observability bill should behave.

1. The real difference: how each one bills you

Feature lists make these two look interchangeable — APM, infra monitoring, logs, RUM, synthetics, AI investigation, the works. The meaningful difference is philosophical, and it shows up on your invoice.

Datadog sells modules. Agent, language-tracer, Single Step Instrumentation, and OpenTelemetry collection paths feed separately metered products. Infrastructure Pro starts at $15/host/month annually; paired APM starts at $31. Standard logs charge for ingest and indexed events separately. Custom-metric allowances depend on plan and contract: the public infrastructure plans include 100 per Pro host or 200 per Enterprise host, with additional usage metered. Host billing can use a high-water-mark plan (excluding the highest 1% of hourly counts) or a monthly/hourly hybrid plan. Core platform user accounts are unlimited, but roles govern access and products such as Incident Response can add seat charges. Billing models.

New Relic sells access, data, and compute. NRDB stores telemetry queried with NRQL. Under user-based pricing, Original Data ingest lists at $0.40/GB and Data Plus at $0.60/GB, with a 100 GB/month free allowance; Pro Full Platform users list at $349/month on the annual prepaid option, and Core users at $49. Hosts are not separately metered, but more hosts can increase telemetry and compute. Pro and Enterprise also offer consumption-based pricing in place of user licenses. Advanced Compute, archive storage/querying, synthetics, and other options can add charges even where a feature is described as part of the platform. Usage-plan rates.

So the two platforms create different cost pressures. Datadog adds product and infrastructure meters; New Relic adds user or compute meters to data charges. One hundred Pro Full Platform users at $349 would cost $34,900/month before data and add-ons, but that arithmetic does not establish which complete platform bill is lower. Autoscaling also needs modeling on both sides: Datadog host charges depend on the contract, while New Relic usage can rise with the telemetry and compute generated by new hosts.

2. Head-to-head: six rounds

The comparisons below are editorial interpretations of documented product scope, not scores from a controlled benchmark.

Round 1 — APM & distributed tracing

Both are top-tier APM products; this is what each company was built on. Datadog's documented toolkit includes Continuous Profiler for function-level CPU and memory attribution, Dynamic Instrumentation to add logs and metrics to a running production service without redeploying, and frontend-to-backend correlation when RUM/APM instrumentation and trace propagation are configured. New Relic counters with two instrumentation paths — language agents with genuinely useful thread-level profiling, plus an eBPF agent (eAPM) for zero-code Kubernetes instrumentation — and Infinite Tracing, which can analyze all spans sent to its trace observer and then select traces for retention through tail-based sampling; this does not guarantee complete instrumentation or eliminate sampling gaps. Account activation and regional availability also apply. New Relic treats OpenTelemetry as a first-class ingestion path. OTel does not make the platform free: the resulting telemetry still counts toward New Relic's data and, where applicable, compute meters.

Evaluation point: Datadog offers continuous profiling and dynamic instrumentation; New Relic offers language-agent profiling and Infinite Tracing. Compare the supported runtime, overhead, retained evidence, and correlation path on the same services before judging effectiveness.

Round 2 — Infrastructure monitoring

Datadog documents Kubernetes monitoring, network performance monitoring, cloud cost management, and more than 1,000 integrations. Check the specific technology and version rather than treating the catalogue count as coverage of every workload. The catch is the pricing mechanics discussed above — per-host fees, high-water-mark billing, and cardinality that converts into custom-metric charges. New Relic documents agent-based host metrics, no-agent cloud integrations for AWS/Azure/GCP, retention that varies by event/metric type, resolution, and account settings — but its billing model is structurally friendlier to dynamic fleets: unlimited hosts, with high-cardinality telemetry affecting data volume rather than creating a separate per-host charge. One caveat: deep APM and infrastructure troubleshooting requires the appropriate user access; model how many engineers truly need Full Platform access instead of assigning it to everyone by default.

Buyer fit: Datadog combines separately scoped infrastructure, network, and security products. New Relic avoids a separate host meter. For autoscaling fleets, compare the resulting telemetry, retention, compute, and access charges; neither product depth nor total savings follows from the billing unit alone.

Round 3 — Log management

Datadog standard logs separate $0.10/GB ingest from $1.70 per million indexed events at 15-day retention. Flex Logs, archives, archive search, and BYOC Logs offer other storage/query paths, so unindexed does not always mean unsearchable. Flex storage and query compute must be priced together. New Relic has no separate standard indexing tier: ingested logs can be queried within applicable retention and access limits, with Original Data ingest at $0.40/GB after the free allowance. Long-term Live Archives add storage and query-compute charges; retention up to seven years is not included in the ingest rate. Event size, indexed proportion, retention, and search frequency determine the comparison. New Relic archive billing.

Buyer fit: Datadog exposes multiple indexing, storage, and query choices; New Relic avoids a separate standard indexing tier. Compare event size, retained volume, query frequency, and access costs before selecting a log strategy.

Round 4 — Digital experience monitoring

The most even round. Both platforms cover browser and mobile RUM (iOS, Android, React Native, Flutter), session replay and synthetic monitoring, and both were named Leaders in the 2025 Gartner Magic Quadrant for Digital Experience Monitoring — Datadog positioned highest for ability to execute, New Relic for the second consecutive year. Datadog's suite extends further into Product Analytics and experimentation, with backend correlation that requires instrumentation and context propagation, but bills each component separately (RUM Measure lists at $0.15 per thousand full-traffic sessions annually, while Investigate and Session Replay use higher, separate meters). New Relic captures Core Web Vitals and interaction signals such as rage and dead clicks. DEM data, user/compute access, and synthetic-check charges must all be included in the budget.

Winner: tie. Datadog if you want product analytics bolted on; New Relic if its data, access, and check allowances fit your usage.

Round 5 — AI and agents

The most current round, and the one where timing matters. Datadog shipped first: Bits AI SRE reached general availability in December 2025 — it can investigate alerts using telemetry and change context to form a root-cause hypothesis; results depend on available data, permissions, and configuration — and is sold through Datadog's AI credit model. Datadog has since expanded the family (security analyst, code assistance, an MCP server that's now GA).

New Relic introduced SRE Agent and Agentic Platform in preview in February 2026. Current documentation calls the incident-investigation product Autopilot, available to Pro/Enterprise organizations with Advanced Compute or qualifying Legacy Compute. It offers diagnostic and remediation suggestions; it does not itself apply those remediations, and it is not available in FedRAMP accounts. Datadog also offers a no-code Bits Agent Builder and collaborative Notebooks, so neither capability should be described as exclusive to New Relic.

Evaluation point: compare evidence quality, permissions, supported integrations, and compute/credit consumption on the same incidents. A historical launch date does not prove current availability, answer quality, or a universal winner. Autopilot scope · Bits Agent Builder.

Round 6 — Security & compliance

Datadog combines Cloud SIEM, workload and application protection, code security, and posture management with observability. Its FedRAMP High authorization applies to the government offering and its approved boundary, not every commercial product. New Relic Security RX documents application and infrastructure vulnerability management, including APM context and third-party findings; it is more than a compliance badge, but that scope is not equivalent to a full Cloud SIEM. New Relic’s public pricing identifies FedRAMP Moderate and HIPAA eligibility for specified enterprise/Data Plus offerings. Confirm the exact deployment, contract, and authorized service boundary. Security RX scope.

Editorial preference: Datadog for a documented Cloud SIEM requirement. Validate detection coverage and response integrations; this is not a security-effectiveness benchmark.

3. Pricing: the math that actually decides this

List prices, side by side

Two worked scenarios

These examples use USD public annual rates and New Relic Original Data without the EU data-center surcharge. Taxes, regional surcharges, commitments, and negotiated terms are excluded.

Scenario A — 100 hosts and 8 Pro Full Platform users: use 5,000 GB of Original Data ingest for New Relic, and 5,000 GB of logs for Datadog. These are component illustrations, not equal full-stack telemetry or retention scopes. Datadog Infrastructure Pro plus paired APM is $4,600/month; log ingest adds $500. If E is the number of millions of events indexed with 15-day retention, the subtotal is $5,100 + $1.70 × E. A log-cost estimate requires event size, indexing proportion, and query-path assumptions.

New Relic’s data-plus-seat subtotal is (5,000 − 100) × $0.40 + 8 × $349 = $4,752/month. This excludes Advanced Compute, extended retention, synthetic checks, support changes, and other add-ons. Datadog’s subtotal also excludes additional telemetry, custom metrics, security, incident-response products, and other usage.

Scenario B — 50 Full Platform users: New Relic’s seat-plus-data subtotal becomes $19,410/month under the same assumptions. Datadog core platform account count alone does not change the subtotal; separate seat-metered products can. Neither result proves a total-cost winner. Measure all signals, event counts, sampling, retention, compute, and access needs before comparing written quotes.

Both vendors have a free offering with different limits: Datadog’s infrastructure plan covers up to 5 hosts with 1-day metric retention, while New Relic’s current free plan includes 100 GB/month and one Full Platform user.

The bill-shock files

Datadog cost risks include the chosen host-billing model, duplicate host identities, high-cardinality custom metrics, and on-demand rates. Deploying an Agent in each Kubernetes Pod does not inherently make every Pod a billable host: verify host identity and the actual host/container meters. High-water-mark pricing excludes the top 1% of hourly counts; a monthly/hourly hybrid is also offered. Neither is accurately described as charging the absolute peak for the entire month.

New Relic's are quieter but real: seat costs scaling linearly with every engineer who touches an incident; ingest at 4x Datadog's per-GB rate punishing teams that don't trim telemetry at the source; and a subtler organizational cost — deep APM and infrastructure troubleshooting depends on the assigned user type, so access policy becomes part of incident design.

5. What users actually say

Review scores and anecdotes are not controlled technical evidence. Use them to form trial questions: can engineers follow an alert through traces and logs; which workflows require additional access; how much configuration is needed; and can the team reproduce the estimated bill? This review does not establish a current G2 rating or a measured ease-of-use winner.

The corporate backdrop is worth a glance, since you're buying a multi-year relationship. Datadog is a public company in full growth mode: Q1 2026 was its first billion-dollar quarter ($1,006M, +32% year over year), with roughly 4,550 customers above $100K ARR, FedRAMP High certification for its government offering, and full-year guidance raised to $4.30–4.34B. New Relic went private in a $6.5B take-private in late 2023 and no longer discloses financials; its public signals are product cadence (Agentic Platform in February 2026, a slate of AI-observability releases at its June 2026 event) and its 13th consecutive Gartner Leader placement.

6. So, which one should you choose?

Choose Datadog if:

• You want one platform for observability and security (Cloud SIEM, runtime protection, code scanning) — today, not on a roadmap.
• Your environment is complex and heterogeneous, and the documented integrations and correlation paths match your technologies; validate the time saved on the same incident workflow.
• Your engineering org is large and everyone needs incident visibility — unlimited core accounts can avoid per-user fees, subject to paid product seats and role permissions.
• You need AI incident investigation in production now (Bits AI SRE is GA) or FedRAMP High for public-sector work.
• You have the FinOps discipline to govern custom metrics, indexing and host sprawl — or the budget not to care.

Choose New Relic if:

• You're cost-sensitive or starting from zero — the free tier can cover eligible workloads within its data, access, and feature limits, with no credit card.
• Your infrastructure is large, dynamic or Kubernetes-heavy, and you prefer to budget for telemetry and access without a separate host meter; model both contracts against the same scaling history.
• You've standardized on OpenTelemetry and prefer a data-ingest model instead of Datadog's product-specific metric types and allotments.
• You want all ingested logs queryable without a separate indexing tier and are prepared to price the retention period you need.
• Your measured data-plus-user quote fits the required retention and access scope, or the Compute model fits better after a complete comparison.

Whichever you choose, do three things first. One: inventory your real numbers — peak host count, monthly GB of logs/traces/metrics, and the honest list of engineers who need full access; then add event counts, retention, query/compute usage, enabled products, and support before requesting comparable quotes. Two: run both against real traffic — New Relic's free tier and Datadog's 14-day trial make a two-week bake-off cheap, and your own invoice estimate beats any list-price arithmetic. Three: prefer OpenTelemetry where it fits — both platforms can receive OTLP data, but a migration still requires validation of semantic conventions, dashboards, alerts, sampling, service topology, retention, and incident workflows.

7. FAQ

Is Datadog or New Relic cheaper?
Neither, universally. Fewer Full Platform users reduce New Relic’s user-based subtotal, while Datadog’s core-account count does not add a user fee. The component examples here do not establish which complete bill is lower; telemetry, retention, compute, and separately metered products remain to be priced. Model your own host count, data volume and headcount before believing either vendor's TCO deck.

Does New Relic really have a free tier? What's the catch?
Yes: 100 GB/month of ingest, one full-platform user and unlimited basic users, no credit card. The catches: usage beyond the included 100 GB requires an upgrade, and only one Full Platform user is included; additional user access and retention can add cost.

Which is better for Kubernetes?
Both document Kubernetes monitoring. Datadog offers Cluster Agent plus separately scoped network and security capabilities; New Relic offers Kubernetes integrations and eBPF instrumentation. Validate runtime coverage, required privileges, and retained evidence in the same cluster. New Relic has no separate host meter, but autoscaling can increase telemetry and compute, so this does not prove lower total cost.

How do their AI features compare right now?
Datadog offers Bits investigation agents and Agent Builder, with AI-credit metering. New Relic’s current incident-investigation documentation uses the name Autopilot (formerly SRE Agent) and requires eligible Pro/Enterprise compute access. Autopilot recommends remediation rather than applying it. Compare current account availability and evidence quality, not the February 2026 preview labels.

Can I use OpenTelemetry with both?
Yes — both ingest OTLP natively. The difference is billing: New Relic meters the resulting OTel data through its ingest and compute model, while Datadog applies its product meters, metric types, and included allotments; high cardinality matters in both cost models.

What about on-call and status pages?
Datadog offers native On-Call, Incident Management, and Status Pages as separately packaged products. New Relic supports incident workflows and integrations, but buyers should verify whether external paging and public status communication are still required. Budget for an incident-management tool either way.

Is my data locked in?
Partially, on both sides. Dashboards, alerts and runbooks accumulate in proprietary query languages (Datadog's per-product syntaxes, New Relic's NRQL) — the longer you stay, the higher the switching cost. OpenTelemetry reduces collector and SDK lock-in, but dashboards, alerts, queries, entity models, sampling rules, and operating workflows still need migration work.

---

The bottom line

This comparison isn't really Datadog versus New Relic — it's module-stacking versus usage pricing. Datadog bets you'll pay for broad product coverage and tightly connected workflows while accepting a bill that compounds with each added meter. New Relic bets you'll trade some of that breadth for pricing you can explain to your CFO in one slide, plus a free tier that lets you start today.

Run your three numbers — hosts, gigabytes, full-access engineers — through both models. The answer usually reveals itself in the spreadsheet. And if it's genuinely close, let the tiebreakers decide: Cloud SIEM coverage can favor Datadog; the data/user/compute model and free-plan scope may favor New Relic. AI and OpenTelemetry workflows should be tested on both.
