LogTide vs Datadog for Log Management

Datadog is a popular SaaS observability platform. LogTide is a self-hosted, open-source log management platform with built-in SIEM. Here’s an honest comparison to help you decide which is right for your team. This page is a head-to-head; for a list of Datadog replacements, see Datadog alternatives, and for a comparison of hosted services, hosted log management compared.

Cost Comparison

Cost is the biggest difference between LogTide and Datadog.

Datadog Pricing

Datadog charges per GB ingested and per million events indexed. The figures below are annual-billing list prices from the Datadog pricing page, checked November 2026. Prices change and contracts vary, so confirm on that page before budgeting. For other vendors and the cloud providers, see the cloud logging pricing overview.

Component	Cost
Log ingestion	$0.10/GB
Log indexing (15-day retention)	$1.70 per million events ($2.55 on-demand)
Flex Storage (long retention)	From $0.05 per million events stored per month
Cloud SIEM	Priced separately, see the Datadog pricing page (not included in the example below)

Example with explicit assumptions (checked November 2026): 100 GB/day is about 3,000 GB/month. We assume about 2 KB per event, so roughly 1.5 billion events/month, all indexed with 15-day retention, annual billing, no Cloud SIEM, no Flex Logs.

• Ingestion: 3,000 GB x $0.10 = $300/month
• Indexing: 1,500 million events x $1.70 = $2,550/month
• Total: $2,850/month ($34,200/year)

Event size drives the indexing line. At 1 KB per event the event count doubles, and at 4 KB it halves, so measure your own average first. Sending only part of the logs to the index lowers the bill too.

LogTide Pricing

LogTide is free, open-source software. You pay for infrastructure. The numbers below are our own assumptions, not vendor list prices, so replace them with quotes from your cloud or hardware provider:

Component	Assumed cost
Software license	Free (AGPLv3)
Cloud VM (8 CPU, 32 GB)	~$150-300/month
Storage (2 TB SSD)	~$50-100/month
SIEM features	Included
Users	Unlimited

Same 100 GB/day scenario:

• Infrastructure: ~$200-400/month
• Total: ~$200-400/month ($2,400-4,800/year)

On these assumptions the infrastructure line is roughly one tenth of the Datadog example. It excludes engineering time for upgrades, backups and capacity planning, and Datadog’s APM, metrics and 700+ integrations, which LogTide does not replace. Whether self-hosting wins depends on your volume and on how much you value that time. For the general case, see self-hosted log management; for a ranked list of options beyond LogTide, see Datadog alternatives.

Feature Comparison

Feature	Datadog	LogTide
Log ingestion (HTTP API)	Yes	Yes
SDKs (Node.js, Python, Go, etc.)	Yes	Yes
OpenTelemetry support	Partial (logs only)	Native OTLP
Full-text search	Yes	Yes
Real-time streaming	Yes	Yes (SSE)
Alert rules	Yes	Yes
Email/webhook notifications	Yes	Yes
Trace correlation	Yes	Yes
Sigma detection rules	No	Built-in
Incident management	Cloud SIEM (separate pricing)	Included
MITRE ATT&CK mapping	Cloud SIEM	Included
Self-hosted option	No	Yes
Custom dashboards	Yes	SIEM dashboard
APM/traces	Yes	Logs + OTLP traces
Infrastructure metrics	Yes	Yes (basic)

Where Datadog Wins

Full observability platform. Datadog offers advanced metrics, traces, logs, and infrastructure monitoring in a single SaaS platform. While LogTide now supports basic metrics, Datadog’s metrics and APM capabilities are significantly more mature.

Zero infrastructure management. As a SaaS product, there’s nothing to deploy or maintain. Your team focuses entirely on using the platform, not running it.

Custom dashboards. Datadog’s dashboard builder is mature with drag-and-drop widgets, formula-based queries, and visualization options that LogTide doesn’t match yet.

Ecosystem integrations. Datadog has 700+ integrations for cloud providers, databases, and third-party services with auto-discovery and auto-instrumentation.

Where LogTide Wins

Cost at scale. For log-heavy workloads, a self-hosted model replaces per-GB and per-event fees with a mostly flat infrastructure cost, so the gap grows with volume (see the example above). Compare the cloud providers’ pricing too if you are on AWS, Azure or GCP.

Data ownership. Your logs stay on infrastructure you control, so there is no third-party processor for log data. That simplifies GDPR work, but compliance still depends on how you run it; see on-premise log management for EU compliance.

Built-in SIEM. LogTide includes Sigma detection rules, MITRE ATT&CK mapping, and incident management at no extra cost. Datadog’s Cloud SIEM is billed separately on top of log costs.

No vendor lock-in. LogTide is AGPLv3 open-source. You can inspect, modify, and extend the code. Your data lives in TimescaleDB or ClickHouse (your choice) that you control.

Unlimited users. LogTide has no per-seat limits or paid roles, so your entire engineering, security, and support teams can have access.

When to Choose Datadog

• You need advanced metrics, APM, and infrastructure monitoring with deep correlation
• Your team doesn’t want to manage infrastructure
• Log volume is small (under 10 GB/day) where cost difference is minimal
• You need 700+ out-of-box integrations
• Budget is not a primary concern

When to Choose LogTide

• Log costs are a significant line item (we would start comparing at 50+ GB/day)
• Data sovereignty or GDPR compliance is required
• You need SIEM capabilities without additional licensing
• You prefer open-source with no vendor lock-in
• You’re comfortable managing a Docker/Kubernetes deployment

SDK Migration

Migrating from the Datadog SDK to the LogTide SDK is straightforward (the Node.js observability walkthrough shows the full setup):

// Before (Datadog)
import { datadogLogs } from '@datadog/browser-logs';

datadogLogs.init({
  clientToken: 'pub_xxx',
  site: 'datadoghq.com',
  service: 'my-app',
});

datadogLogs.logger.info('User logged in', { userId: 123 });

// After (LogTide)
import { LogTideClient } from '@logtide/sdk-node';

const client = new LogTideClient({
  apiUrl: 'http://logtide.internal:8080',
  apiKey: 'lp_xxx',
});

client.info('my-app', 'User logged in', { userId: 123 });

Concept Mapping

Datadog	LogTide	Notes
Organization	Organization	1:1 mapping
Index	Project	Logs are scoped to projects
Service	Service	1:1 mapping
Log Pipeline	N/A (automatic)	LogTide auto-parses JSON
Monitor	Alert Rule	Similar functionality
Dashboard	SIEM Dashboard	Security-focused dashboards
API Key	API Key (per project)	Prefix: lp_
Cloud SIEM	Sigma Rules + Incidents	Included at no extra cost
