The short version

  • Each has a real cost: Redpanda the community edition is source-available rather than OSI open source, which matters for some procurement; Zabbix the database is the scaling limit, and high frequency polling grows history tables fast enough that untuned installations hit housekeeping stalls and query timeouts within months.
  • They diverge on capability: Redpanda covers Kafka API compatible, Zabbix covers Agent and agentless collection.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Redpanda

  • Kafka workloads where the operational cost of running Kafka is the blockernot Zabbix
  • Latency-sensitive streaming where tail latency mattersnot Zabbix
  • Smaller teams wanting streaming without a dedicated platform groupnot Zabbix

Zabbix

  • A service provider monitoring thousands of customer devices where per-device commercial licensing is the largest line itemnot Redpanda
  • Branch or industrial sites with unreliable links that need local collection and bufferingnot Redpanda
  • Mixed estates where the same tool must poll SNMP switches, Linux hosts, Windows servers and Java applicationsnot Redpanda
  • Replacing an aging Nagios installation while keeping script-based checks that already existnot Redpanda

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Redpanda

  • The community edition is source-available rather than OSI open source, which matters for some procurement
  • Kafka API compatibility is high but not total, and deep ecosystem tools can hit gaps
  • Smaller community than Kafka, so fewer people have solved your problem before
  • Some operational and tiered-storage features are enterprise-only

Zabbix

  • The database is the scaling limit, and high frequency polling grows history tables fast enough that untuned installations hit housekeeping stalls and query timeouts within months.
  • Initial configuration is heavy; getting useful alerting rather than noise requires understanding trigger expressions, macros and template inheritance, which is a multi-week learning curve for a team new to it.
  • The AGPLv3 change at version 7.0 affects anyone offering Zabbix over a network as part of a commercial service, and that obligation is easy to inherit accidentally during an upgrade.
  • The web interface is functional rather than pleasant, and many sites end up running Grafana alongside it purely for presentation, which is a second system to maintain.
  • Upgrades between major versions touch the database schema and can take hours on large history tables, so the maintenance window is proportional to how much data you kept.

Answered from the vendors’ own pages

Redpanda: Is Redpanda free?

A community edition is free and source-available. Enterprise features and Redpanda Cloud are paid, and the licence is not OSI open source.

Zabbix: Is Zabbix genuinely free for commercial use?

The software has no licence fee at any scale. From version 7.0 it is AGPLv3, so offering it as a network service to third parties carries source distribution obligations.

Redpanda: Can I use my Kafka clients?

Yes. Redpanda implements the Kafka API, so existing clients and most tooling connect without changes.

Zabbix: What is the real cost of running it?

Database administration and the person who tunes it. Budget for PostgreSQL with TimescaleDB and someone who owns the retention policy.

Redpanda: Why remove ZooKeeper and the JVM?

Both are significant sources of Kafka’s operational burden — tuning, coordination and failure modes. Removing them is the core of Redpanda’s pitch.

Zabbix: How does it compare to a commercial per-device tool?

It removes the licence line entirely and adds an operations line. Below a few hundred devices the commercial tool is often cheaper in total; above that Zabbix wins clearly.
