OpenWA hardware requirements at a glance
OpenWA supports WhatsApp-related automation and its managed browser sessions. Size it around parallel jobs, task duration, browser sessions and separately executed scripts, including the complete service stack and durable data. A scheduler is smaller than the jobs it starts. Include worker processes, browser/model integrations and external API limits; bound concurrency before adding more workers.
- RAM
- The linked source does not establish a fixed numerical whole-host baseline for this complete workload. Size the full stack during the busy operation described below.
- CPU
- The linked source does not establish a fixed numerical whole-host baseline for this complete workload. Measure CPU use during realistic activity.
- Storage
- Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts.
- Required services
- Follow the service topology in the linked upstream deployment for the chosen edition; include every required database, worker and storage service. The repository references PostgreSQL, SQLite, Redis / Valkey, S3-compatible object storage. These may be integrations or alternative backends; install only the services required by your selected topology.
- Main sizing variable
- parallel jobs, task duration, browser sessions and separately executed scripts.
- Practical Zima starting point
- ZimaBoard 2 832 with SSD-backed active state is an editorial starting point for modest use. Include the OS and all companion services; it is not a measured capacity guarantee.
From official requirements to the right setup
Plan the complete OpenWA workload before selecting a server.
-
Official requirements
Choose the exact edition, stable release and supported container/runtime. Follow the service topology in the linked upstream deployment for the chosen edition; include every required database, worker and storage service. The repository references PostgreSQL, SQLite, Redis / Valkey, S3-compatible object storage. These may be integrations or alternative backends; install only the services required by your selected topology.
-
Confirm your needs
Test a representative busy operation: parallel jobs, task duration, browser sessions and separately executed scripts. Record peak resident memory, CPU, disk latency and completion time, including other containers.
-
Leave room to grow
Place active state on reliable persistent storage. Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts. Budget working space for an upgrade or import and test recovery before relying on the deployment.
-
Run it on ZimaOS
On ZimaOS, use a compatible amd64 container through Custom Install and reproduce all required services, volume mappings and device access. Select the currently documented browser or protocol backend. Session memory examples vary by backend; WhatsApp platform restrictions and authentication are separate from host capacity.

When to upgrade your hardware
Use observed OpenWA workload pressure to decide when an upgrade is warranted.
Busy operations exceed the available window
The complete stack runs short of memory
Persistent data approaches available capacity
Inspect the application and each required service for OOM events, sustained swap or growing queues. Reduce unnecessary concurrency before adding capacity.
Shared hosts and background work.Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts. Track primary state and backup retention separately.
Long-lived installations and growing collections.Plan hardware growth with confidence
Address storage, memory, compute and deployment limits separately.
Use suitable active storage
Put latency-sensitive application/database state on durable local SSD storage and keep recoverable copies.
SATA or PCIe SSD according to measured data growth.Add memory for the complete stack
Choose a higher-RAM host when peak application and companion-service usage leaves inadequate OS headroom.
ZimaBoard 2 832 or ZimaBoard 2 1664 according to the measured constraint.Separate capacity from compute
A multi-drive system helps when retained content and backup storage are the problem; it is not automatically a faster application.
ZimaCube 2 when a broader multi-drive workload justifies it.Fix the observed bottleneck
Select the currently documented browser or protocol backend. Session memory examples vary by backend; WhatsApp platform restrictions and authentication are separate from host capacity.
Check service configuration, I/O and network behavior before selecting a stronger CPU.Can it run on ZimaOS?
Official one-click ZimaOS availability has not been certified for this guide. Use the supported upstream runtime and service topology; consider Custom Install only when a maintained compatible container and all required host capabilities are available.

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.
Frequently asked questions
Answers to OpenWA RAM, CPU, storage, Docker, database and ZimaOS sizing questions.
How much RAM should I plan for OpenWA?
The linked source does not establish a fixed numerical whole-host baseline for this complete workload. Size the full stack during the busy operation described below. Include ZimaOS, the application and its companion services rather than reserving the entire machine for one container.
What drives the CPU requirement?
The linked source does not establish a fixed numerical whole-host baseline for this complete workload. Measure CPU use during realistic activity. The workload to test is: parallel jobs, task duration, browser sessions and separately executed scripts.
Which data must survive a container update?
Persist workflow definitions, credentials, job metadata, logs and retained input/output artifacts. Preserve a consistent database/file set and verify that your recovery procedure restores a working application.
What other services belong in the budget?
Follow the service topology in the linked upstream deployment for the chosen edition; include every required database, worker and storage service. The repository references PostgreSQL, SQLite, Redis / Valkey, S3-compatible object storage. These may be integrations or alternative backends; install only the services required by your selected topology.
