# Coroot vs Datadog

Comprehensive comparison of observability platforms: architecture, features, costs, and deployment models

### Platform Model

Open source vs Enterprise SaaS

### Data Storage

On-premises vs Cloud-managed platforms

### Pricing Model

Simple per-CPU vs Multi-dimensional billing

## Architecture & Technology

Fundamentally different approaches to observability

### Coroot

🔒 On-Premises Complete Platform

**Full observability stack on your infrastructure.** Store ALL data without compromise, enterprise-grade guarantees, complete control over your observability pipeline.

- **Hybrid Data Collection**  
eBPF auto-instrumentation + OpenTelemetry compatibility - best of both worlds
- **Store Everything**  
No data sampling compromises - 10x compression means unlimited retention without cost fears
- **Full AI Root Cause Analysis**  
Complete intelligent incident analysis - not just chat assistance but actual RCA automation.
- **Zero Configuration Setup**  
Pre-built dashboards, alerts, and inspections - insights within minutes, not months of setup
- **Enterprise Control & Support**  
Commercial support with SLAs, professional services, air-gapped deployments, unlimited customization.

### Datadog

☁️ Cloud-Based SaaS Platform

**Mature APM-focused platform.** Battle-tested by Fortune 500, extensive integrations, but data sampling required due to cost constraints.

- **APM + Infrastructure Focus**  
Primary strength in application performance monitoring with some eBPF unified observability features
- **Data Sampling Required**  
High-volume costs force data sampling and retention limits - can't store everything
- **AI Chat + Limited RCA**  
Watchdog RCA for specific scenarios + AI chat assistant - not comprehensive root cause automation
- **Manual Configuration Required**  
Build your own dashboards, configure alerts, set up monitoring - weeks/months to production-ready setup
- **Enterprise SLA & Support**  
99.9% SLA, 24/7 support, SOC2/HIPAA/GDPR compliance, established enterprise contracts

## Feature Comparison

How the platforms compare across key observability capabilities

| Feature | Coroot | Datadog |
| --- | --- | --- |
| Metrics & Infrastructure Monitoring | Comprehensive telemetry via eBPF including network monitoring | Comprehensive infrastructure monitoring with 900+ integrations |
| Distributed Tracing | eBPF auto-tracing + OpenTelemetry compatibility | SDK instrumentation |

| Continuous Profiling | Always-on profiling with <1% overhead - pinpoint performance bottlenecks down to exact line of code | Continuous profiler for production applications - additional cost per profiled host |
| Cloud Cost Monitoring | Automatic cloud cost tracking without account access - calculates cross-AZ and egress costs per application | Cloud Cost Management with AWS/Azure/GCP integration - requires cloud account access and additional setup |
| Synthetic Monitoring | Not available - focuses on internal observability | HTTP checks, synthetic monitoring, uptime monitoring |
| Real User Monitoring (RUM) | Not available - backend/infrastructure focused | Frontend performance monitoring and user analytics |
| Security & SIEM | Not available - pure observability platform | Security monitoring, threat detection, compliance |

Base APM + $0.10/GB over 150GB/host + $1.70/M indexed spans

#### Additional costs:

- Log ingestion: $0.10/GB + $1.70/M indexed events  
- Trace ingestion overage: $0.10/GB (over 150GB/host)  
- Indexed spans overage: $1.70/million spans  
- Cloud egress to Datadog: $0.09/GB (AWS/GCP/Azure charges)  
- Continuous Profiling: $19/profiled host  
- High watermark billing (99th percentile usage)

### Example: 50-Host Environment

#### Coroot Enterprise

- Coroot licenses (200 cores × $1) $200  
- Infrastructure (4 vCPU, 16GB RAM) $120  
- Storage (5TB SSD - 2x replication) $200  
- **Total monthly cost** $520  
  
\* 5TB dataset stored efficiently with ClickHouse compression + 2x replication for HA

#### Datadog Enterprise

- Infrastructure Enterprise (50 hosts × $23) $1,150  
- APM Base (50 hosts × $31) $1,550  
- Continuous Profiling (50 hosts × $19) $950  
- Log ingestion (3TB/month × $0.10) $300  
- Trace ingestion overage (2TB × $0.10) $200  
- Indexed spans overage (10M × $1.70) $17  
- Cloud egress to Datadog (5TB × $0.09) $450  
- **Total monthly cost** $4,667  
  
Monthly savings with Coroot: $4,267 (11.7x less expensive)

\* Coroot includes infrastructure costs for ClickHouse, Prometheus, and storage. ClickHouse provides 10x compression reducing storage costs significantly. Datadog based on moderate enterprise usage: 3TB logs/month, 2TB trace ingestion, 10M indexed spans/month. Includes cloud egress costs to send data to Datadog (5TB × $0.09). Actual costs vary significantly based on usage patterns, data volume, and cloud provider pricing.
