Thousands of feeds, frequent updates and readability plugins increase parser/database activity.
Heavy RSS users.Tiny Tiny RSS Hardware Requirements: RAM, CPU, PostgreSQL & Storage
Plan Tiny Tiny RSS hardware for RAM, CPU, PostgreSQL, feed updates and Docker, with practical ZimaOS custom-install recommendations.
Tiny Tiny RSS requirements at a glance
tt-rss is lightweight for normal personal use, but its official Docker stack includes PostgreSQL, an updater and a web frontend.
- RAM
- No numerical official whole-host RAM minimum published. Docker examples include a PHP worker memory limit setting, but that is not a server minimum.
- CPU
- No numerical official core minimum. Feed refreshes, article parsing and plugins create the main CPU bursts.
- Database
- The recommended Docker setup uses PostgreSQL; the current example uses PostgreSQL 17.
- Architecture
- Current official images are published for linux/amd64 and linux/arm64.
- Docker
- Docker is the main and recommended deployment method; support for non-Docker setups may be limited.
- Best Zima starting point
- ZimaBoard 2 832 is comfortably sufficient for tt-rss plus PostgreSQL in normal personal or small shared use.
From official requirements to the right setup
Size tt-rss as a lightweight PHP/feed stack plus PostgreSQL.
-
Official requirements
Use the official Docker installation path with the app, PostgreSQL, updater and web-nginx services.
-
Confirm your needs
Estimate feed count, refresh frequency, content extraction and plugin use because these determine recurring CPU/database work.
-
Leave room to grow
Persist PostgreSQL and app volumes, and use the optional backup workflow or an external database backup process.
-
Run it on ZimaOS
On ZimaOS, use Install Custom App with tt-rss's official Compose pattern, map the HTTP port behind a reverse proxy, and keep PostgreSQL on durable storage.

Official minimum requirements
Tiny Tiny RSS publishes a detailed Docker architecture but no numerical host hardware minimum.
Do not convert the example PHP worker memory limit into a server RAM requirement. Whole-host sizing should include PostgreSQL, updater and feed-processing activity.
| Requirement | Official minimum | What this supports |
|---|---|---|
| RAM minimum | No numerical official minimum published | PHP worker memory settings are process limits, not host RAM. |
| CPU minimum | No numerical official minimum published | Feed parsing and updater workload drive demand. |
| Recommended deployment | Docker | Official docs call Docker the main/recommended path. |
| Database | PostgreSQL | Current official Compose architecture. |
| Current example DB image | PostgreSQL 17 | Current installation guide example. |
| Container architectures | linux/amd64 and linux/arm64 | Current official image support. |
When to upgrade your hardware
tt-rss should scale when feed volume, plugins or database history creates sustained load.
Feed refresh queues become slow
PostgreSQL history grows
Plugins and extracted media increase storage
Long retention and full-text search increase database size and cache pressure.
Long-running archives.Extra content and custom plugins can grow app volumes and processing time.
Highly customized installations.Plan hardware growth with confidence
Scale tt-rss around PostgreSQL and refresh workload rather than the web frontend.
Use SSD-backed PostgreSQL storage
Fast durable storage improves refresh writes, searches and backups.
Use SATA/NVMe with ZimaBoard 2.Keep normal deployments on ZimaBoard 2 832
8 GB and four cores provide ample practical headroom for tt-rss plus PostgreSQL.
ZimaBoard 2 832.Use 16 GB for very large feeds or many co-hosted apps
Extra RAM benefits PostgreSQL cache and the wider server stack.
ZimaBoard 2 1664.Use ZimaCube only for broader storage duties
tt-rss alone rarely justifies a six-bay NAS.
ZimaCube 2 Standard.Can it run on ZimaOS?
No public official ZimaOS one-click Tiny Tiny RSS App Store detail page was verified for this guide. Use the Custom Install route unless a concrete current listing is confirmed at publish time.
Custom install Tiny Tiny RSS in ZimaOS
Use the official tt-rss Docker Compose pattern with PostgreSQL, updater and web-nginx services, persist the app/database volumes and map the HTTP port behind your reverse proxy.
Custom install Tiny Tiny RSS in the ZimaOS app ↗Use Tiny Tiny RSS official Docker installation
Follow the current upstream deployment documentation rather than relying on outdated third-party examples.

tt-rss is lightweight enough for ZimaBoard 2 832 in normal use.
Is this a normal personal feed reader or a large/high-refresh archive?
Personal / normal use
Use ZimaBoard 2 832 with SSD-backed PostgreSQL.
- Best starting pointZimaBoard 2 832
Very large feed set / many other apps
Add RAM for PostgreSQL and the wider host.
- More host headroomZimaBoard 2 1664
- Broader storage platformZimaCube 2 Standard
These are practical recommendations, not official feed-count performance tiers.
| Zima hardware | Best for | Example workload | Core configuration | Recommended boundary | Next step |
|---|---|---|---|---|---|
| ZimaBoard 2 832 | Normal tt-rss installations. | tt-rss, PostgreSQL, updater and normal refresh workloads. |
|
Far more compute than the frontend needs; PostgreSQL/storage quality matters more. | Get Now |
| ZimaBoard 2 1664 | Large feed libraries and multi-app hosts. | More PostgreSQL cache and co-hosted services. |
|
Extra RAM is for the whole host. | Get Now |
| ZimaCube 2 Standard | tt-rss as one service on a broader NAS. | RSS archive plus unrelated backup/storage workloads. |

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.
