LogFlow vs Datadog: Pricing, Features & Honest Comparison (2026)

Datadog is the market leader in observability. If your team needs infrastructure metrics, APM traces, and logs in one place, Datadog delivers. But if you primarily need log management — collecting, searching, and alerting on logs from your applications — you're paying for a lot of features you don't use, at a price that scales painfully with volume.

TL;DR: Datadog Log Management charges per GB ingested and indexed. At 100 GB/month, you're paying $250-$400/month just for logs. LogFlow's Growth plan covers 100 GB for $49/month flat. If you don't need Datadog's APM and infrastructure monitoring, LogFlow is the better choice.

Pricing Comparison

	LogFlow	Datadog
Free tier	500 MB/mo, 3 days	No free logs tier
Entry paid	$19/mo (10 GB, 14 days)	~$15/host/mo + $0.10/GB ingested
10 GB/month	$19/mo	~$50-100/mo
100 GB/month	$49/mo	~$250-400/mo
500 GB/month	$149/mo	~$1,200-2,000/mo
Pricing model	Flat monthly	Per host + per GB ingested + per GB indexed

Datadog's log pricing has two components: ingestion ($0.10/GB) and indexing ($0.0025/GB/day for 3-day retention). The costs multiply quickly for teams with multiple services or long retention requirements.

When to Choose LogFlow

• Your primary need is application log management
• You want predictable pricing that doesn't spike with traffic
• You're a startup or indie team that can't justify Datadog's cost
• You want anomaly detection without complex configuration
• You don't need full APM (metrics + traces + profiles)

When to Choose Datadog

• You need unified observability — logs, metrics, APM traces, and infrastructure in one platform
• You're running on-premise infrastructure that needs the Datadog agent
• You need advanced dashboards and correlation across all signal types
• Your team already uses Datadog for metrics and wants to consolidate
• You have enterprise compliance requirements that Datadog certifications cover

Migration from Datadog to LogFlow

1. Create a LogFlow account — free tier available
2. Install the SDK: npm install @getlogflow/js
3. Replace your Datadog logger with the LogFlow logger (same API shape)
4. Set up alerts to mirror your existing Datadog monitors
5. Keep Datadog running in parallel for 2-4 weeks until you're confident

The LogFlow quickstart gets you running in under 5 minutes.

Frequently Asked Questions

Is LogFlow cheaper than Datadog?

For log management specifically, yes — significantly. At 100 GB/month, LogFlow costs $49/month versus $250-400/month for Datadog. At 500 GB/month, the gap is even larger: $149/month versus $1,200-2,000/month. Datadog includes APM and infrastructure monitoring in those prices, but if you don't need those, you're overpaying.

Does LogFlow have a Datadog agent replacement?

LogFlow uses its own SDK (@getlogflow/js) and supports the HTTP API and OpenTelemetry. It doesn't have an infrastructure agent that collects host metrics. If you need host-level CPU, memory, and disk metrics alongside logs, you'd need a separate tool for that.

Can LogFlow replace Datadog for APM?

Not fully. LogFlow handles logs and log-based trace correlation (linking logs by trace ID). It doesn't provide distributed traces with flamegraphs, service maps, or application performance profiling. For full APM, Datadog remains the comprehensive choice.

What is Datadog's minimum monthly cost?

Datadog's infrastructure monitoring starts at $15/host/month. Log management is additional: $0.10/GB ingested. A 5-host setup sending 50 GB of logs would cost at minimum $75 (hosts) + $5 (ingestion) = $80/month, plus indexing costs. In practice, most teams pay $200-500+/month.

Does LogFlow offer anomaly detection like Datadog Watchdog?

Yes. LogFlow includes built-in anomaly detection (error rate spikes, volume spikes, volume drops, and silence detection) on all paid plans. Datadog Watchdog requires APM and is bundled with higher-tier plans. LogFlow's anomaly detection works without any configuration — it learns your baseline automatically.
