Graylog
Pros
- + Graylog Open is free with no volume restrictions — self-hosted logging without per-GB billing
- + Full data ownership and residency control; runs on your own hardware or private cloud
- + Long track record (project since 2009) with active community and solid documentation
- + Commercial editions let you stay on the same deployment as you grow into SIEM use cases
Cons
- - SSPL license is source-available, not OSI open source — restricts offering it as a service
- - Enterprise/Security/Cloud pricing is quote-based with no public calculator
- - Self-hosting carries real operational load: OpenSearch/Data Node, MongoDB, index and retention management
- - Audit logging and SIEM content sit in paid editions, not Open
SigNoz
Pros
- + Usage-based pricing with published per-unit rates ($0.30/GB logs and traces, $0.10/mn metric samples) and no per-user or per-host billing
- + OpenTelemetry-native: no proprietary SDKs, so instrumentation does not lock you in
- + Logs, metrics, traces, APM, exceptions and alerts correlated in one ClickHouse-backed product
- + Self-hostable open-source community edition plus cloud regions in the US, EU and India with SOC2 Type II and HIPAA compliance
- + Worked pricing examples and a bill calculator published — costs are computable before you commit
Cons
- - No published uptime SLA below the Enterprise tier (from $4,000/month)
- - Self-hosted community edition makes storage, scaling, upgrades and backups your operational problem
- - Usage bills move with retention choices and noisy telemetry; the $49 entry tier shows a struck-through $199 base price
- - Narrower turnkey integration ecosystem than Datadog; RBAC is beta and audit logs/multi-tenancy are roadmap items
- - Migration tooling and dedicated Slack support are gated at spends above $999/month
