Quick comparison: Datadog vs Zabbix
Common trade-offs teams weigh when staying on Datadog versus moving to Zabbix. These are general, commonly-reported considerations — not statements of fact about any vendor — so check them against your own contract and the vendors' current terms.
- Already in production — no migration effort or risk
- Mature ecosystem with vendor support and SLAs
- Per-host plus per-GB ingest billing is hard to predict
- Costs spike with custom metrics and high cardinality
- Each module (APM, logs, RUM) is billed separately
- Bill shock at scale is widely reported
- Ongoing usage-based (host + ingest) cost to budget for
- Higher vendor lock-in to weigh
- Open source — no license fees
- No vendor lock-in
- Cost model: Free (open source)
- Requires a migration (~18 weeks, high effort)
- Community support by default — paid support optional
- Higher operational learning curve
