Beszel vs Zabbix
Zabbix is enterprise-grade monitoring - SNMP, network discovery, custom triggers - but it runs as a full server + database + frontend stack. Beszel gives you server and Docker monitoring in 5 minutes with a <10MB agent. Pick the right tool for your scale.
Beszel vs Zabbix: The Verdict
Beszel is a lightweight, zero-config monitoring tool for servers and Docker: <10MB per agent, 5-minute setup, no database. Zabbix is enterprise-grade monitoring with SNMP, network discovery, custom triggers, and distributed proxies, but it needs a full server + database + web frontend and real time to run. Choose Beszel for homelabs and small VPS fleets. Choose Zabbix when you monitor network gear, thousands of metrics, or need deep custom alerting.

| Feature | Zabbix | Beszel |
|---|---|---|
| Starting Price | Free (open source), but needs a server + database | $3/mo (hosted on InstaPods) |
| Resource Footprint | Server + DB + frontend: 2 CPU / 8GB RAM for even small setups | <10MB per agent |
| Setup Time | Hours (install server, database, frontend, configure templates) | 5 minutes |
| Components Needed | 3+ (server, database, web frontend) plus agents | 2 (hub + agent) |
| Database Required | Yes (PostgreSQL, MySQL/MariaDB, or TimescaleDB) | No - the hub stores metrics itself |
| Docker Monitoring | Via templates/plugins (manual setup) | Built-in per-container stats |
| SNMP / Network Devices | Full SNMP, IPMI, network discovery | Not included (servers + Docker only) |
| Alerting | Powerful triggers and actions (heavy config) | Simple threshold alerts (email, webhook, Telegram) |
| Learning Curve | Steep (items, triggers, templates, macros) | None - works on first load |
| Source Code | Open source (AGPLv3 since 7.0) | Open source (MIT) |
Where Zabbix Gets Expensive
Trade-offs to weigh before committing.
Needs a Full Server Stack
Zabbix is three moving parts - the Zabbix server, a relational database, and a PHP web frontend. Even a small install wants roughly 2 CPUs and 8GB of RAM before you monitor a single host.
A Database to Run and Back Up
Zabbix stores everything in PostgreSQL or MySQL. That means tuning, backups, and (on larger fleets) running the database on its own box. Beszel has no external database to manage.
Steep Learning Curve
Items, triggers, templates, macros, actions - Zabbix is built for full-time monitoring teams. Getting a useful dashboard takes hours of reading docs, not minutes.
Overkill for a Handful of Servers
If you run 3-10 servers and a few Docker apps, Zabbix's network discovery, SNMP, and distributed proxies are power you will never touch - at the cost of all that overhead.
Why Self-Host with Beszel?
What you get when you pick this stack.
5-Minute Setup, No Database
Deploy the hub, run the agent on each server, and monitoring starts immediately. No database to install, tune, or back up.
<10MB Per Agent
Beszel's agent uses under 10MB of RAM. It runs on the same $3/mo pod as your apps without eating your resources.
Docker-Native
Built-in per-container CPU, memory, and network tracking. No templates or plugins to wire up.
Reads Right on First Load
CPU, memory, disk, network, and Docker - all there with zero config and no query language to learn.
Real Cost Comparison
Monitoring 5 servers with Docker containers.
- Zabbix software: free (open source)
- But the Zabbix server + database needs ~2 CPU / 8GB RAM (a $20-40/mo VPS)
- Plus initial setup and ongoing database maintenance
- Agents: lightweight, free
- InstaPods Launch plan: $3/mo (Beszel hub)
- Beszel agents: free on all 5 servers
- <50MB total RAM across all agents
- Setup time: 15 minutes
Frequently Asked Questions
Is Beszel a good Zabbix alternative?
Yes, if you monitor servers and Docker and want it simple. Beszel covers CPU, memory, disk, network, and per-container Docker stats with a <10MB agent and zero config. It does not replace Zabbix for SNMP, network-device monitoring, or large distributed fleets.
Is Zabbix free?
The Zabbix software is free and open source (AGPLv3). But running it means hosting a server, a database, and a web frontend - for even a small setup that is roughly a 2 CPU / 8GB machine, so the real cost is the infrastructure plus the time to maintain it.
Does Beszel need a database like Zabbix?
No. The Beszel hub stores metrics itself - there is no PostgreSQL or MySQL to install, tune, or back up. That is why it fits comfortably on a $3/mo pod.
When should I pick Zabbix over Beszel?
When you need SNMP/IPMI, network-device discovery, custom triggers across thousands of metrics, or distributed monitoring with proxies. Zabbix is enterprise-grade; Beszel is built for self-hosters watching a handful of servers.
