LogTide vs Datadog for Log Management
LogTide vs Datadog: open-source, self-hosted log management with built-in SIEM and unlimited users. Save up to 90% versus Datadog's per-GB + per-seat pricing.
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.
Cost Comparison
Cost is the biggest difference between LogTide and Datadog.
Datadog Pricing
Datadog charges based on log volume plus per-user fees:
| Component | Cost |
|---|---|
| Log ingestion | $0.10/GB (with commitment) to $1.70/GB (on-demand) |
| Log retention (15 days) | Included with ingestion |
| Log retention (30+ days) | $0.05-$0.15/GB/month |
| Per-user (Pro) | $23/user/month |
| Cloud SIEM | $0.20/GB additional |
Real-world example: A mid-size SaaS company ingesting 100 GB/day:
- Log ingestion: ~$3,000/month
- 5 users (Pro): $115/month
- Cloud SIEM: $600/month
- Total: ~$3,715/month ($44,580/year)
LogTide Pricing
LogTide is free, open-source software. You pay only for infrastructure:
| Component | 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: ~$300/month ($3,600/year)
Savings: ~$41,000/year (92%)

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, LogTide’s self-hosted model saves 80-95% compared to Datadog. The more logs you generate, the bigger the savings.
Data ownership. Your logs never leave your infrastructure. No third-party data processing agreements needed. Full GDPR compliance with EU data sovereignty.
Built-in SIEM. LogTide includes Sigma detection rules, MITRE ATT&CK mapping, and incident management at no extra cost. Datadog’s Cloud SIEM adds $0.20/GB 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. No per-seat pricing. Add your entire engineering, security, and support teams without cost concerns.
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 (50+ GB/day)
- Data sovereignty or GDPR compliance is required
- You need SIEM capabilities without additional licensing
- You want to avoid per-user pricing
- You prefer open-source with no vendor lock-in
- You’re comfortable managing a Docker/Kubernetes deployment
SDK Migration
Migrating from Datadog SDK to LogTide SDK is straightforward:
// 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

|---|---|---|
| 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 |

Frequently Asked Questions
Is there a free, open-source alternative to Datadog logs?
Yes — LogTide is open-source and free to self-host. You run it on your own infrastructure with unlimited users, instead of paying Datadog's per-GB ingestion plus per-seat fees.
How much cheaper is LogTide than Datadog?
Datadog log management runs roughly $0.10-$1.70/GB ingested plus indexing and per-user charges. Self-hosting LogTide typically saves up to 90% at scale, since cost is driven by infrastructure rather than volume and seats.
How do I migrate from Datadog to LogTide?
Follow the LogTide Datadog migration guide: point your existing log shippers (Agent, Vector, Fluent Bit) at LogTide's HTTP endpoint, run both in parallel to validate dashboards and alerts, then cut over and turn off Datadog ingestion.
Does LogTide replace Datadog's security monitoring?
For logs, yes — LogTide includes built-in SIEM with Sigma rules and MITRE ATT&CK mapping at no extra cost. Note Datadog also covers APM, metrics and infrastructure monitoring beyond logs; LogTide focuses on log management and log-based detection.
