Zabbix
Pros
- + Free, no per-host or per-seat licensing — cost stays flat as monitored infrastructure grows
- + Deep protocol coverage: agent2, SNMP, IPMI, JMX, HTTP, synthetic checks, Kubernetes
- + 25 years of field-hardened releases with a disciplined LTS support schedule (7.0 LTS to June 2029)
- + Zabbix Cloud removes the ops burden without changing the tool; 5-day trial without a credit card
- + Open source under AGPLv3 with a documented API, Terraform provider and large template ecosystem
Cons
- - Steep learning curve — configuration UI, trigger syntax and template design need real investment
- - Zabbix Cloud drops values at random above the NVPS cap and disk only grows (once per 24h, never shrinks)
- - No published numeric uptime SLA or public region list for Zabbix Cloud; compliance certifications still in progress
- - Weaker on logs and distributed tracing than modern observability suites; self-hosting means you own the upkeep
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
