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
Sentry
Pros
- + Industry-standard error grouping and stack traces with code context
- + Free Developer plan at $0 including error monitoring and tracing
- + Framework SDKs make setup a one-afternoon job
- + EU data residency (Frankfurt) at no extra cost on all plans
- + Covers tracing, session replay, release health, cron and uptime monitors in one subscription
- + Self-hostable server code for teams that must run their own stack
Cons
- - Usage-based overage on errors, spans, and replays can spike bills unexpectedly
- - Real setup work needed to control noise (grouping, filters, sampling)
- - No public uptime SLA on self-serve plans
- - No APAC data region; some account metadata stays in the US even on EU orgs
- - Self-hosted deployment is operationally heavy and the license is not plain OSI open source
