Graylog Pricing 2026

Graylog offers free Open Source (self-hosted, unlimited logs) and paid cloud/enterprise plans. Graylog Cloud Operations starts at $1,250/month for 10GB/day. Graylog Cloud Security starts at $1,550/month for 10GB/day with SIEM features. Graylog API Security starts at $1,500/month. Self-hosted Enterprise pricing is custom based on daily volume. Open Source is free but requires infrastructure ($500-5,000/month) and DevOps time (20-40 hours/month).

Yes, Graylog Open Source is completely free with unlimited log ingestion, dashboards, alerts, and no licensing restrictions. However, it requires self-hosting (servers, Elasticsearch/OpenSearch, MongoDB) costing $500-5,000/month in infrastructure plus 20-40 hours/month DevOps maintenance. Free version lacks enterprise features (archival, advanced RBAC, ML anomaly detection, professional support). Graylog Cloud ($1,250+/month) eliminates infrastructure management.

Graylog is significantly cheaper than Splunk. For 10GB/day: Graylog Cloud $1,250/month ($15,000/year) vs Splunk Cloud ~$36,500/year - Graylog saves 60%. At 50GB/day: Graylog ~$5,000-6,500/month vs Splunk ~$150,000+/year. Graylog Open Source (free self-hosted) offers best ROI if you have DevOps resources. Splunk provides more advanced ML, Enterprise Security, and ecosystem apps; Graylog excels at cost-effective log analysis and SIEM-lite.

Operations ($1,250/month for 10GB/day) includes: managed SaaS, search, dashboards, alerts, stream processing, RBAC, 99.5% SLA, email/chat support. Security ($1,550/month) adds: built-in Sigma rules, threat intelligence, event correlation, incident investigation, compliance reporting, log integrity verification, anomaly detection, 99.9% SLA, priority security support. Choose Operations for general log management; choose Security for SOC/SIEM use cases.

Yes, Graylog Cloud and Enterprise pricing is negotiable for 50GB+ daily volumes. Expect 15-25% discounts with annual commitments. At 100GB+ daily, negotiate 25-35% discounts and include extended retention, professional services, and training. Best timing: fiscal year-end (Q4) or quarter-end. Leverage competitive quotes from Logz.io, Sumo Logic, or self-hosted ELK estimates. Multi-year contracts (2-3 years) unlock deeper discounts (30-40%).

Graylog Open Source is excellent for small teams with DevOps skills willing to self-host - unlimited logs at infrastructure cost ($500-2,000/month for 10-50GB/day). However, Graylog Cloud ($1,250/month minimum) is expensive for startups vs alternatives: Logz.io $333/month (10GB/day), Papertrail $230/month (100GB/month), or Loggly $159/month (1GB/day). Choose Graylog if you need SIEM-like features or already run Elasticsearch; choose alternatives for simpler use cases.

Self-hosted Graylog requires: (1) Graylog server nodes (1-3+ for HA, 4GB+ RAM each), (2) Elasticsearch/OpenSearch cluster (3+ nodes, 8GB+ RAM, SSD storage for hot data), (3) MongoDB (replica set, 4GB RAM), (4) Load balancer for HA. Minimum setup for 10GB/day: 3 Graylog nodes + 3 ES nodes + MongoDB = ~$1,000-2,000/month AWS/cloud costs. At 100GB/day, expect $5,000-10,000/month infrastructure. Add DevOps time (20-40 hours/month).

Graylog does not publicly advertise dedicated education or startup programs. However, Open Source is ideal for cash-constrained startups - completely free with self-hosting. For Graylog Cloud/Enterprise, contact sales with proof of accelerator enrollment (Y Combinator, Techstars) or AWS/GCP startup credits to request custom pricing. Academic institutions should inquire about research/education licensing for large deployments requiring enterprise features and support.

Graylog is built on ELK (Elasticsearch, Logstash, Kibana equivalent) but offers: (1) Superior stream processing and routing vs Logstash, (2) More intuitive UI than Kibana for log search/alerts, (3) Built-in alerting vs ELK's X-Pack requirement, (4) Better RBAC and multi-tenancy, (5) Free Open Source vs ELK's restrictive Elastic License. However, ELK has larger ecosystem and advanced features (Canvas, ML). Choose Graylog for easier management; choose ELK for flexibility and ecosystem.

Graylog Security ($1,550/month for 10GB/day) provides SIEM-lite capabilities at 60-80% cost savings vs Splunk Enterprise Security. It includes: Sigma rules, threat intelligence, event correlation, incident investigation, compliance reporting, and anomaly detection. However, Splunk offers more mature security content, advanced ML (UBA/UEBA), extensive app ecosystem, and deeper analyst workflows. Choose Graylog for mid-market SOCs (50-200GB/day); choose Splunk for Fortune 500 security operations requiring best-in-class features.

Graylog Cloud includes 30-day searchable retention by default, extendable to 90-180 days with additional storage costs. For long-term compliance archival (years), Graylog Enterprise (self-hosted) offers built-in Archive feature to export old logs to S3/MinIO/HDFS at $0.023/GB/month. Open Source requires custom scripting or using Curator to move old indices to cold storage. Unlike Splunk's SmartStore, Graylog's archival is simpler but less integrated with search.

Graylog requires configuring three separate systems: Graylog itself, Elasticsearch, and MongoDB, all in a Linux environment. This demands significant technical expertise. However, reviewers note that while the task initially seems daunting, the actual configuration is kept as simple as possible once you understand the components.

You'll need experience with Linux system administration, Elasticsearch configuration, and MongoDB management. The Open Source (Free) plan requires you to manage all infrastructure yourself. Teams without this expertise should consider Graylog Cloud - Operations ($1,250/month) or Graylog Cloud - Security ($1,550/month), which are managed services.

The most frequently reported issues are disk space management and index size limits. When disk space fills up or indexes exceed configured limits, the system can become corrupt and require manual index deletion. Organizations need to monitor disk usage proactively and plan for adequate storage capacity.

The Open Source (Free) plan is production-capable and widely used, but lacks enterprise features like archiving (which reviewers note should be standard) and comes with no official support. It's well-suited for teams with strong technical expertise who can manage the infrastructure themselves. For mission-critical environments or teams needing support, the paid Cloud or Enterprise options are recommended.
