What Are the Cheapest Alternatives to Datadog for Startups? 

Datadog’s per-host pricing compounds in ways that catch most startups off guard. Infrastructure monitoring starts at $15 per host per month, billed annually. APM adds another $31 per host per month on top. Log management is billed separately at $0.10 per GB ingested. Containers cost an additional $5 per 10 containers per month. For a startup running 20 hosts with APM enabled and 50GB of daily log volume, Datadog’s monthly bill regularly exceeds $5,000 before any enterprise discounts. And that is before custom metric overages, synthetics, RUM, or database monitoring.

Several mature alternatives cover the core observability needs of a startup (traces, metrics, logs, error tracking, alerting) at a fraction of that cost. The right choice depends on whether your primary pain point is the per-host pricing model, the data residency requirement, the cost of APM, or the lack of a genuine free tier.

Why Datadog Gets Expensive for Startups

1. Every module is billed separately. Infrastructure monitoring, APM, log management, synthetic monitoring, RUM, database monitoring, and security are each separate products with separate meters. Enabling APM does not include logs. Enabling logs does not include APM. A team enabling five Datadog products on 20 hosts is paying five separate bills that multiply together.
2. APM doubles the per-host cost. APM at $31/host/month adds more to the bill than the base infrastructure monitoring at $15/host/month. Running both costs $46/host/month at a minimum. For a 20-host startup, that is $920/month before logs, containers, or custom metrics.
3. Log ingestion and indexing are billed separately. Datadog charges $0.10/GB for log ingestion and $1.70 per million events for indexed log search at 15-day retention. A startup ingesting 50GB/day of logs pays $150/month in ingestion plus additional indexing costs on top. Enabling verbose logging during an incident can cause an unexpected bill spike.
4. Custom metric overages accumulate silently. Each host on the Pro plan includes 100 custom metrics. Beyond that, custom metric overages are billed based on usage. High-cardinality instrumentation (tagging metrics with user IDs, request IDs, or dynamic values) creates exponential custom metric counts that are invisible until the invoice arrives.
5. Container monitoring adds a separate charge. Beyond the included 5 or 10 containers per host license, additional containers are billed at $0.002 per container per hour, or $1 per container per month on a prepaid basis. A 20-host cluster running 200 containers incurs container costs on top of host and APM costs.
6. 99th percentile billing means autoscaling events cost a full month. Datadog meters hosts hourly and bills at the peak of the lower 99% of hours. An autoscaling event during a five-day traffic spike that doubles your host count sets your bill at that higher level for the entire month, not just for those five days.
7. Kubernetes billing by node can spike with misconfiguration. In Kubernetes, Datadog bills per node. A DaemonSet deployment is correct and cost-efficient. A sidecar deployment makes every pod count as a separate host, multiplying costs by the average number of pods per node with no warning.

Top Datadog Alternatives

1. CubeAPM

CubeAPM is a full-stack observability platform that runs inside your own infrastructure. It covers APM, log management, infrastructure monitoring (hosts, databases, containers, cloud services), Real User Monitoring, synthetic monitoring, error tracking, and Kubernetes monitoring in a single platform, all through a single OTLP-native ingestion pipeline.

Unlike Datadog, CubeAPM has no per-host fees, no per-module charges, no per-user fees, and no custom metric taxes. The bill is determined entirely by data volume, making it predictable as your infrastructure scales.

Pricing: $0.15/GB ingestion. No per-host fees. No per-user fees. No module add-ons.

At 50GB/day of telemetry, that is $225/month regardless of how many hosts, users, containers, or services you are running. As your host count doubles, the bill does not double with it unless your telemetry volume doubles proportionally.

CubeAPM uses AI-based smart sampling that preserves slow, error-prone, and unusual traces while cutting ingestion volume significantly, keeping costs low even as request volume grows. All data stays inside your own cloud environment and never leaves your infrastructure.

Best for: Startups wanting a full Datadog replacement with predictable pricing, data residency control, and no per-host billing surprises as they scale. Teams handling sensitive data who cannot send telemetry to a third-party SaaS. Teams that have hit unexpected Datadog bills and need immediate cost reduction.

Limitations: Requires self-hosted deployment. Not suitable for teams that need a fully managed SaaS with no infrastructure responsibilities.

2. New Relic

New Relic is the closest functional SaaS alternative to Datadog. It covers APM, distributed tracing, infrastructure monitoring, log management, browser monitoring, synthetic monitoring, mobile monitoring, and alerting in one platform with no per-host charges. Pricing is data-volume-based, which makes it far more predictable than Datadog at startup scale.

Pricing:

Tier	Data included	Users included	Cost
Free (perpetual)	100GB/month from any source	1 full platform user, unlimited basic users	$0
Standard	100GB/month free, then $0.40/GB	Up to 5 full platform users	Contact for pricing
Pro	100GB/month free, then $0.40/GB	Unlimited full platform users	Contact for pricing

The free tier includes full access to all 50+ New Relic capabilities including APM with distributed tracing, infrastructure monitoring, log management, synthetic monitoring, browser monitoring, serverless monitoring, and more. Basic users (unlimited, free on all tiers) can query data and build dashboards. One full platform user gets access to everything at no cost.

Best for: Startups that want a full-featured Datadog SaaS alternative at no initial cost. Teams that can stay within 100GB/month of ingest with a small engineering team get the complete platform for free.

Limitations: Data retention on the free tier is 8 days for most data types. Full platform user pricing on paid tiers can increase costs as teams grow beyond 5 engineers. Data leaves your infrastructure and flows to New Relic’s cloud.

3. Grafana Cloud

Grafana Cloud is the managed version of the LGTM stack (Loki for logs, Grafana for visualization, Tempo for traces, Mimir for metrics). It provides full-stack observability without the operational overhead of running it yourself. The paid tier is usage-based with no per-host fees.

Pricing:

Tier	What is included	Cost
Free	2,232 host hours/month, 14-day retention, full platform access including Grafana Assistant AI	$0
Pro (paid)	13-month metric retention, 30-day log/trace/profile retention, usage-based billing	Pay as you go

The free tier includes everything Grafana Cloud offers including the AI assistant. The paid tier charges on active series (metrics), GB ingested (logs), and host hours. There are no per-host license fees.

Best for: Teams already using Prometheus and Grafana who want a managed upgrade with no tooling change. Teams that want usage-based pricing with no per-host fees and are comfortable with the Grafana UI.

Limitations: The free tier has 14-day retention, which is not enough for trend analysis over weeks or months. The Grafana UI has a steeper learning curve than Datadog or New Relic for engineers who are new to it.

Sentry

Sentry focuses on error tracking, performance monitoring, session replay, and release health. It does not replace infrastructure monitoring and does not provide host CPU, memory, or disk metrics. For startups where the primary observability need is catching and fixing application errors fast, Sentry is the strongest focused tool at the lowest price.

Pricing (verified directly from sentry.io/pricing, May 2026):

Plan	Errors/month	Users	Logs included	Cost
Developer	5,000	1	5GB	Free forever
Team	50,000	Unlimited	5GB	$26/month
Business	100,000	Unlimited	5GB	$80/month

Log ingestion beyond 5GB costs $0.50/GB. Additional errors beyond the plan limit are available on a pay-as-you-go basis.

Sentry’s event-based pricing means costs are determined by error and transaction volume, not by host count. A 50-host application that produces few errors costs the same as a 2-host application with the same error volume.

Best for: Startups that want best-in-class error tracking, stack traces with AI-assisted root cause analysis (Seer), release tracking, and session replay. Particularly strong for frontend and full-stack JavaScript teams.

Limitations: Sentry is not an infrastructure monitoring tool. Most production teams use Sentry alongside a separate metrics tool rather than instead of one.

Self-Hosted LGTM Stack

Running Loki (logs), Grafana (dashboards), Tempo (traces), and Mimir or Prometheus (metrics) on your own infrastructure has no per-host or per-metric licensing cost. The OTel Collector routes telemetry from your applications to these backends.

Cost: Infrastructure cost only (cloud VMs or Kubernetes nodes running the stack). No software licensing fees.

Best for: Infrastructure-mature teams with a dedicated SRE or platform engineer who can own the stack. Teams that have outgrown free tiers and want to avoid per-host pricing at significant scale.

Limitations: Deploying, configuring, scaling, and maintaining a production-grade LGTM stack requires meaningful ongoing engineering effort. Loki needs object storage for log data. Tempo needs object storage for traces. Mimir requires more configuration than single-node Prometheus for high availability. A startup with a three-person engineering team does not have the capacity to run this reliably.

Summary

Datadog’s per-host, per-module pricing model makes it expensive for startups before they reach the scale where its enterprise features become necessary. The seven specific pain points that drive up Datadog costs (stacked module billing, 99th percentile host metering, APM doubling per-host cost, separate log indexing fees, custom metric overages, container add-on charges, and Kubernetes sidecar misconfiguration risk) can all be avoided with the right alternative.

CubeAPM eliminates all of these by billing purely on data volume at $0.15/GB with no per-host, per-user, or per-module fees. New Relic offers the most generous free SaaS tier in the market at 100GB/month with full platform access. Grafana Cloud provides a managed LGTM stack with usage-based pricing and no per-host charges. Sentry is the right choice for error-first observability at $26/month for unlimited users.

Tool	Starting cost	Pricing model	Data stays in your cloud
CubeAPM	$0.15/GB ingestion	Per GB, no per-host or per-user fees	Yes (self-hosted)
New Relic	$0 (100GB/month free, then $0.40/GB)	Per GB ingested + per full platform user	No
Grafana Cloud	$0 (free tier, 14-day retention)	Usage-based (series, GB, host hours)	Partial
Sentry	$0 (Developer), $26/month (Team)	Per event volume	Optional (open source)
LGTM self-hosted	Infrastructure cost only	No licensing	Yes
