TrueNAS provides a great Apps UI, but it’s not ideal for:
- quickly scanning all containers
- tailing logs across multiple services
- spotting which ports map to which services
- lightweight troubleshooting without SSH
When it comes to debugging on why an App wouldn’t deploy / crash on TrueNas, you’ll need some handy tools instead of using the TrueNAS UI which is often cumbersome.
Two lightweight tools often recommended are Dockpeek and Dozzle. At first glance they look similar -both connect to Docker and expose information in a web UI – but in practice they solve very different problems.
This post compares Dockpeek and Dozzle specifically from a TrueNAS SCALE perspective, and helps you decide which one (or both) makes sense for your setup.
Dockpeek is best described as a Docker overview dashboard
It gives you:
- a list of containers
- exposed ports with clickable links
- container status
- basic log viewing
- image version / update awareness
it works especially well if:
- you run many web services
- you want quick access to UIs
- you don’t want full container control exposed
- Portainer feels too heavy
Dockpeek pairs nicely with Homepage / Homarr, or even replaces them for Docker.
Dozzle is a real-time Docker log viewer—and nothing more
Its entire focus is:
- streaming container logs live
- searching logs
- filtering by container
- debugging runtime issues
Dozzle does not try to show ports, links, images, or container metadata beyond what’s needed for logs.
It’s perfect when:
- an app won’t start
- a container is restarting
- you need logs now!
- you want to avoid SSH
Dozzle is essentially docker logs -f in a browser and feels like a debugging tool, not a dashboard.
Feature Comparison
| Feature | Dockpeek | Dozzle |
|---|---|---|
| Primary purpose | Docker overview dashboard | Real-time log viewer |
| Live log streaming | Basic | Excellent |
| Log filtering / search | Limited | Strong |
| Container status | Yes | Yes (secondary) |
| Port mappings | Yes | No |
| Clickable service links | Yes | No |
| Image update awareness | Yes | No |
| Multi-host support | Yes | Yes (via agents) |
| Persistent log storage | No | No |
| Resource usage | Low | Very low |
Final Thoughts
Most people end up running both! They complement each other extremely well:
- Dockpeek → “What’s running?”
- Dozzle → “Why is it broken?”
If care about observability without complexity, these two tools cover nearly everything you need. Because both are lightweight, there’s little downside to deploying them together.
