CryptPad requirements at a glance
CryptPad's current administrator guide gives a concrete production baseline and additional security/network requirements.
- RAM
- Official recommended minimum on the host machine: 2 GB RAM.
- CPU
- Official recommended minimum: 2 CPUs.
- Storage
- Official recommended minimum: 20 GB, depending on planned usage.
- Domains
- Two domains or subdomains are needed to take full advantage of CryptPad's security features.
- Docker
- Docker is now officially supported; the project publishes official AMD64 and ARM64 images and a Compose file.
- Best Zima starting point
- ZimaBoard 2 832 exceeds the base 2 GB/2-CPU/20 GB requirement; use 16 GB or ZimaCube 2 when storage, users or optional OnlyOffice grow.
From official requirements to the right setup
Start from CryptPad's official production minimum, then add storage and memory for real encrypted collaboration data and optional document editing components.
-
Official requirements
Reserve at least 2 GB RAM, 2 CPUs and 20 GB storage as the current official host baseline.
-
Confirm your needs
Plan two domains/subdomains and HTTPS so CryptPad can use its intended sandboxing/security model.
-
Leave room to grow
Estimate blob/file/datastore growth and whether OnlyOffice is enabled. The official Docker Compose file persists multiple data directories and optional OnlyOffice assets.
-
Run it on ZimaOS
On ZimaOS, use Install Custom App with CryptPad's official image/Compose pattern, persist all documented data directories, configure the main and sandbox domains, and preserve the high nofile limit.
Check every playback client
- Main domain
- Sandbox domain
- Expected user count
- File/blob storage growth
- OnlyOffice requirement
- Persistent data directories
- Backup strategy
- Reverse proxy/HTTPS
Official minimum requirements
CryptPad's current production installation guide publishes explicit minimum hardware recommendations.
The 2 GB RAM, 2 CPU and 20 GB storage figures are genuine upstream minimum recommendations. Treat them as a starting point, not a guarantee for larger public instances or optional OnlyOffice workloads.
| Requirement | Official minimum | What this supports |
|---|---|---|
| Operating system | Debian 12 recommended in current guide | The production installation page uses Debian 12 as the host baseline. |
| RAM | 2 GB minimum recommended | Current development-team recommendation. |
| CPU | 2 CPUs minimum recommended | Current development-team recommendation. |
| Storage | 20 GB minimum recommended | Depends on planned usage and stored encrypted content. |
| Domains | 2 domains or subdomains | Needed to take full advantage of CryptPad's security features. |
| Docker | Officially supported | The project publishes Dockerfile, Compose and official AMD64/ARM64 images. |
When to upgrade your hardware
CryptPad should scale when encrypted content, collaborative users or optional office components outgrow the base profile.
Stored blobs/files grow beyond the initial disk plan
Concurrent collaboration increases
OnlyOffice is enabled
More simultaneous users and WebSocket activity increase CPU, memory and file-descriptor pressure.
Shared team or community instances.Optional document/spreadsheet/presentation editing adds a separate application workload beyond core CryptPad.
Teams needing richer office-document editing.Plan hardware growth with confidence
Scale CryptPad around persistent encrypted storage and collaboration load, with OnlyOffice treated as a separate workload.
Move CryptPad data to SSD-backed storage
Fast durable storage improves file/datastore access and simplifies backup planning.
Use SATA/NVMe with ZimaBoard 2 or SSD tiers on ZimaCube 2.Move to 16 GB for larger teams or OnlyOffice
Extra RAM gives CryptPad and optional office services more headroom.
ZimaBoard 2 1664 is a compact 16 GB step-up.Use multi-drive capacity for larger encrypted file stores
File/blob growth can dominate capacity in a long-running collaborative deployment.
ZimaCube 2 Standard provides six HDD bays and SSD expansion.Use stronger CPU for heavier collaboration/office workloads
More users and optional office components can justify more general-purpose compute.
ZimaCube 2 Pro provides a stronger Core i5 platform.Can it run on ZimaOS?
CryptPad is not currently confirmed as a public official one-click ZimaOS App Store page in the sources checked for this guide. It can be deployed through Install Custom App using CryptPad's official Docker image and Compose files.
Custom install CryptPad in ZimaOS
Use Install Custom App with the official CryptPad image, persist blob/block/data/datastore/customize directories, configure main and sandbox domains, and retain the documented file-descriptor limit.
Custom install CryptPad in the ZimaOS app ↗Use CryptPad's officially supported Docker deployment
Current upstream documentation publishes official Docker images and Compose support for AMD64 and ARM64.
Review CryptPad Docker installation ↗Keep the two-domain security model intact
CryptPad's production documentation requires separate main and sandbox domains/subdomains for its intended security isolation.
Review CryptPad installation guidance ↗Choose Zima hardware for CryptPad
CryptPad's 2 GB/2-CPU baseline fits ZimaBoard 2 comfortably; storage and optional OnlyOffice determine when to move up.
Is this a small CryptPad instance or a larger collaboration/file/OnlyOffice workload?
Small team / core CryptPad
ZimaBoard 2 832 exceeds the official base hardware minimum; add durable SSD-backed storage.
- Best starting pointZimaBoard 2 832
- More memory headroomZimaBoard 2 1664
Larger file store or OnlyOffice collaboration
Use ZimaCube when storage expansion and stronger CPU/memory matter for the wider stack.
- Storage-first platformZimaCube 2 Standard
- Higher-headroom platformZimaCube 2 Pro
These are workload-based recommendations, not guarantees for concurrent collaborators or file capacity.
| Zima hardware | Best for | Example workload | Core configuration | Recommended boundary | Next step |
|---|---|---|---|---|---|
| ZimaBoard 2 832 | Small CryptPad team instances. | Core CryptPad, WebSocket collaboration and moderate encrypted file storage. |
|
Add at least 20 GB suitable persistent storage; the 32 GB eMMC should not be the only long-term data location. | Get Now |
| ZimaBoard 2 1664 | Larger CryptPad usage or optional office components. | More concurrent collaboration, file activity and additional services. |
|
16 GB is headroom beyond the official minimum, not a published CryptPad tier. | Get Now |
| ZimaCube 2 Standard | Encrypted collaboration with larger retained files/backups. | CryptPad plus multi-drive data retention and other NAS services. |
|
Choose Standard mainly for storage topology; heavier OnlyOffice workloads may benefit more from Pro CPU/RAM. | Get Now |
| ZimaCube 2 Pro | Heavier collaboration and optional office-service stack. | More users, WebSockets, OnlyOffice and broader app consolidation. |
|
Actual concurrent capacity still depends on usage patterns and OnlyOffice workload. | Get Now |

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.
