PostgreSQL becomes a better fit as concurrency rises and is required for features such as fuzzy search.
Larger shared recipe servers.Requisiti hardware di Mealie: RAM, CPU, database e spazio di archiviazione
Pianifica l'hardware per Mealie in base a RAM, CPU, SQLite o PostgreSQL, dati delle ricette e backup, con consigli pratici per un'installazione personalizzata di ZimaOS.
Mealie requirements at a glance
Mealie is light for normal household use, but the correct database choice matters on NAS storage.
- RAM
- No numerical official whole-host minimum published. Current official Compose examples cap the Mealie container at 1000 MB to limit unnecessary Python pre-allocation.
- CPU
- No numerical official core minimum published. Normal recipe browsing, imports and household use are lightweight.
- Database
- SQLite is ideal for roughly 1–20 users in normal local deployments, but Mealie explicitly warns NAS users to use PostgreSQL instead.
- Storage
- No universal official disk minimum. Recipe data, images, database files and backups determine capacity.
- Architecture
- Official containers support linux/amd64 and linux/arm64; 32-bit ARM is not supported.
- Best Zima starting point
- ZimaBoard 2 832 is more than sufficient; on ZimaOS, PostgreSQL is the safer path when app data is NAS-backed.
From official requirements to the right setup
Size Mealie as a lightweight app plus its database and persistent recipe data.
-
Official requirements
Use the official Mealie container and pin a versioned tag rather than relying blindly on latest.
-
Confirm your needs
Choose the database from the storage topology. SQLite suits small local deployments, but Mealie warns that SQLite on NAS storage can corrupt or lock.
-
Leave room to grow
Persist /app/data and, with PostgreSQL, the database volume separately. Store Mealie backup files outside the same server for real disaster recovery.
-
Run it on ZimaOS
On ZimaOS, use Install Custom App with the official image; for NAS-backed persistence, prefer the PostgreSQL Compose pattern and map container port 9000 to an available host port.

- Household users
- SQLite or PostgreSQL
- NAS-backed app data
- Recipe/image growth
- Backup destination
- Container memory limit
- Host port mapping
- Other ZimaOS apps
Official minimum requirements
Mealie publishes deployment examples and database guidance rather than a numerical host-hardware minimum.
The 1000 MB value is an explicit container limit in current examples, not a whole-server minimum. On a NAS host, PostgreSQL is the important upstream recommendation.
| Requirement | Official minimum | What this supports |
|---|---|---|
| Whole-host RAM minimum | No numerical official minimum published | The official example uses a 1000 MB container limit. |
| CPU minimum | No numerical official minimum published | Normal household use is lightweight. |
| Mealie container memory example | 1000 MB limit | Used in current SQLite and PostgreSQL Compose examples. |
| SQLite guidance | Ideal for about 1–20 users | Not recommended when Mealie data is stored on NAS. |
| NAS database guidance | Use PostgreSQL | Upstream warns SQLite on NAS can corrupt or lock. |
| Architectures | linux/amd64 and linux/arm64 | 32-bit ARM is not supported. |
When to upgrade your hardware
Mealie rarely needs a hardware upgrade by itself; database topology and the wider home-server stack usually matter more.
More concurrent users or fuzzy search
Recipe images and backups grow
Many other apps share the host
Media and backup retention can become the main storage requirement.
Long-running collections.Mealie may stay light while other databases, media and automation services consume system RAM and I/O.
All-in-one ZimaOS systems.Plan hardware growth with confidence
Scale Mealie around database reliability and persistence rather than raw compute.
Use PostgreSQL on NAS-backed storage
This follows Mealie’s explicit warning against SQLite on NAS filesystems.
ZimaBoard 2 832 already has ample compute for Mealie plus PostgreSQL.Put PostgreSQL and app data on SSD
Fast durable storage improves database latency and backup operations.
Use SATA/NVMe with ZimaBoard 2 or SSD tiers on ZimaCube 2.Use 16 GB only for the broader stack
Mealie itself does not justify 16 GB; extra RAM is for PostgreSQL and other apps.
ZimaBoard 2 1664.Use ZimaCube only for broader storage needs
Large backups, media libraries or many other apps—not Mealie—justify six-bay storage.
ZimaCube 2 Standard.Can it run on ZimaOS?
No public official ZimaOS one-click Mealie App Store page was verified for this guide. Mealie can still be deployed through Install Custom App.
Custom install Mealie in ZimaOS
Use the official Mealie container or PostgreSQL Compose example, persist /app/data and the database, and map port 9000.
Custom install Mealie in the ZimaOS app ↗Use Mealie official Docker installation
Current docs provide SQLite and PostgreSQL Compose templates and recommend pinned version tags.
Review Mealie installation checklist ↗Prefer PostgreSQL for NAS-backed data
Mealie explicitly warns that SQLite on NAS storage can cause corruption or locked-database errors.
Review Mealie SQLite guidance ↗Choose Zima hardware for Mealie
Mealie is lightweight; choose hardware for the database and other services sharing the host.
Is Mealie mostly standalone or part of a larger home-server stack?
Standalone / normal household use
Use the smallest current ZimaBoard 2 and PostgreSQL if data is NAS-backed.
- Best starting pointZimaBoard 2 832
Many other apps or broader storage duties
Add RAM or a larger storage platform for the whole host.
- More app headroomZimaBoard 2 1664
- Storage-first platformZimaCube 2 Standard
These are practical recommendations, not official user-count guarantees.

Zima Blade Little yet Powerful
Maybe I am not digital natives but I live with PCs since 12 years old in 1984 when IBM PC clone come to my home. Many years have passed and many operating system I've tried. For me Zima blade and CasaOS was a quantum leap for home PC enthusiast and server lab machine to make me stay curious and relevant for this era.
★★★★★
Very good!!
I use ZimaCube Pro as 5th Proxmox cluster node. It runs several VMs and containers, including a VM with GPU passthrough to run a self-hosted LLM. A specific LXC container runs a Samba server for NAS capabilities using four of six RAID 6 SATA HDDs with ZFS.
★★★★★
Great innovation for mini server!
It is very useful and makes a powerful mini server for many purposes, including university and college students in engineering and electronics. Thank you so much for making this server.

Avaliação ZimaBoard 2
Construí um servidor de uso pessoal. O desempenho está muito bom e funciona perfeitamente onde quer que eu esteja. A surpresa é não dependermos de grandes estruturas para termos nosso próprio servidor de dados. Como iniciante, estou gostando bastante do ZimaOS, pois ele é simples e eficiente.
