Overseerr server requirements at a glance
Overseerr is a web-based media request manager, not a media transcoder. Its own hardware demand is modest, but as of 2026 it is a legacy project: the Overseerr and Jellyseerr teams merged into Seerr, the Overseerr repository no longer receives new features or major updates, and LinuxServer deprecated its Overseerr image. ZimaOS still lists Overseerr, so this page is most useful for maintaining or migrating an existing installation.
- Project status
- Overseerr is superseded by Seerr. The official Overseerr repository recommends migration, and LinuxServer marks its Overseerr container deprecated and no longer updated.
- CPU
- The Overseerr project does not publish a numerical official CPU minimum. Normal work is web UI, API, metadata and request-management activity rather than video encoding.
- RAM
- The Overseerr project does not publish a numerical official RAM minimum. Server Compass labels its legacy Overseerr template as 512 MB+ RAM; treat that as third-party deployment guidance, not an official minimum.
- Storage
- Overseerr needs persistent configuration/database storage, not a media library of its own. Preserve the config data across container updates and before migrating to Seerr.
- Network
- Reliable API connectivity to Plex, Radarr, Sonarr and metadata services matters more than high LAN throughput. Remote user access also requires a secure web-access path.
- Best Zima starting point
- For an existing Overseerr instance, ZimaBoard 2 832 has ample host resources for the request manager itself. Choose more RAM or ZimaCube 2 because of the surrounding Plex/Arr/download/storage stack, not Overseerr alone.
From official requirements to the right setup
For Overseerr in 2026, the first sizing decision is whether you are maintaining an existing instance or starting a new request-management deployment.
-
Official requirements
If this is a new deployment, prefer Seerr. The upstream Overseerr repository says Overseerr is being superseded and recommends migrating for continued support and development.
-
Confirm your needs
If you are maintaining an existing Overseerr installation, size the request manager separately from Plex, Radarr, Sonarr and download clients. Overseerr coordinates requests and metadata; the media server and automation stack carry most of the storage and compute load.
-
Leave room to grow
Keep the Overseerr configuration/database path persistent and backed up. The official Seerr migration guide can automatically migrate existing Overseerr data on first startup, but preserving the source appdata is essential until the migration has been verified.
-
Run it on ZimaOS
On ZimaOS, confirm the existing Overseerr app is reachable, integrations work and the host has enough combined CPU/RAM for the full stack. Then plan migration to Seerr rather than investing in Overseerr-specific hardware.
Check every playback client
- Existing Overseerr deployment or new installation
- Number of Plex users and request volume
- Plex, Radarr and Sonarr API connectivity
- Persistent config/database storage and backups
- Reverse proxy or secure remote access path
- Other media automation containers sharing the host
- Plex transcoding demand, which belongs to Plex rather than Overseerr
- Migration plan from Overseerr to Seerr
Official minimum requirements
The Overseerr project does not publish numerical CPU or RAM minimums. A current third-party Server Compass template labels Overseerr as 512 MB+ RAM, but the project itself is now superseded by Seerr. Two similarly named sources supplied for this topic are unrelated products and must not be used for Overseerr sizing.
Do not treat 512 MB RAM or any unrelated Overseer hardware table as an official Overseerr requirement. For existing installs, preserve config data and size the full Plex/Arr stack. For new installs, use Seerr and follow its current documentation.
| Requirement | Official minimum | What this supports |
|---|---|---|
| Official CPU minimum | No numerical minimum published | Overseerr upstream does not define a CPU core-count or clock-speed floor. |
| Official RAM minimum | No numerical minimum published | Server Compass lists 512 MB+ RAM for its deployment template, but that is third-party guidance rather than an Overseerr upstream specification. |
| Third-party RAM guidance | 512 MB+ RAM | Server Compass currently labels its Overseerr template this way. It should be treated as a practical template floor, not a guaranteed production recommendation. |
| Persistent storage | No official numerical capacity minimum | Overseerr stores configuration and application/database data. It does not store the Plex media library itself. |
| GPU | No dedicated GPU requirement | Overseerr does not transcode media. Plex hardware acceleration, if used, is a separate Plex server requirement. |
| Current support status | Superseded by Seerr | The official Overseerr repository no longer receives new features or major updates, and LinuxServer deprecated its Overseerr image. |
When to upgrade your hardware
Do not buy stronger hardware for Overseerr in isolation unless measurements show it is the bottleneck. Most upgrade triggers come from the rest of the media stack.
The Plex and Arr stack grows around Overseerr
More users and integrations increase background activity
You migrate to Seerr and add broader media-server support
More users, requests, library checks, notifications and API integrations create additional web/database/network work. This can justify more host headroom, although it is still much lighter than media transcoding.
For shared Plex libraries with many request users or numerous notification/integration workflows.Seerr is the actively developed successor and combines Overseerr/Jellyseerr functionality. Plan CPU/RAM for Seerr plus the full media stack rather than scaling a legacy Overseerr container indefinitely.
For existing Overseerr users planning a supported long-term deployment.Plan hardware growth with confidence
The most important growth path for Overseerr is migration and stack hygiene, not a dedicated hardware accelerator.
Migrate to Seerr before expanding the deployment
The official Seerr migration guide supports existing Overseerr data and automatically migrates it on first startup. Verify Seerr before removing the old container or appdata.
No special upgrade is required just to migrate; ensure enough free storage for a safe copy of application data and backups.Keep config/database data persistent
Request history, users, settings and integrations depend on persistent application data. Back this up independently of the container image.
Use reliable eMMC/SSD/NVMe for appdata; bulk media capacity is determined by Plex and the NAS, not Overseerr.Add RAM for co-hosted media services
If Plex, Sonarr, Radarr, download clients and dashboards share ZimaOS, total memory usage becomes the sizing variable. Upgrade the host for the combined stack.
8 GB is a comfortable compact starting point; 16 GB provides more room for a denser media stack.Do not add a GPU for Overseerr
Overseerr only manages requests and integrations. A dedicated GPU should be justified by Plex/Jellyfin transcoding, AI or another workload, not by Overseerr.
Prioritize application persistence, RAM and the storage/network needs of the broader server.Can it run on ZimaOS?
ZimaOS still lists Overseerr today, but the upstream project has moved on to Seerr. Existing users can maintain the app while planning migration.
Existing Overseerr installs remain discoverable in ZimaOS
The current ZimaOS App Store still has an Overseerr listing. Treat it as a legacy deployment because upstream development has moved to Seerr.
Open Overseerr in the ZimaOS App StorePreserve Overseerr appdata before changing containers
Keep configuration/database data persistent and backed up. Do not remove the old appdata until the Seerr migration has been completed and verified.
Read the official Seerr migration guidePrefer Seerr for new deployments
Overseerr upstream states that it is being superseded by Seerr, while LinuxServer says the old Overseerr image is deprecated and will not be updated.
Read the Seerr release announcementChoose Zima hardware for an Overseerr or Seerr media stack
Existing Overseerr itself is light. Hardware selection should follow the services around it—Plex, Sonarr, Radarr, download clients, media storage and any future Seerr deployment.
Are you maintaining legacy Overseerr or building a new media-request stack?
Maintaining an existing Overseerr instance
Keep it stable, back up appdata and size hardware for the surrounding Plex/Arr stack. Plan migration to Seerr rather than scaling Overseerr as a long-term platform.
- Light existing Overseerr plus a few media automation appsZimaBoard 2 832
- More containers, users and memory headroomZimaBoard 2 1664
Building or expanding the long-term media server
Use Seerr for the request layer and choose ZimaCube 2 only when integrated storage, heavier media services or network requirements justify it.
- Integrated multi-drive media server and automation stackZimaCube 2 Standard
- Heavier multitasking, larger workflows or 10GbE requirementZimaCube 2 Pro
Overseerr has no upstream numerical CPU/RAM minimum, is superseded by Seerr and should not be used to justify oversized hardware. Third-party 512 MB+ guidance is not a performance guarantee.
| Zima hardware | Best for | Example workload | Core configuration | Recommended boundary | Next step |
|---|---|---|---|---|---|
| ZimaBoard 2 832 | An existing Overseerr or new Seerr request layer beside a modest Plex/Arr stack. | Web requests, metadata/API integrations and several light media automation containers. |

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
These answers distinguish legacy Overseerr requirements from Seerr migration and from the much heavier Plex/media-server workload around it.
How much RAM does Overseerr need?
Overseerr does not publish an official numerical RAM minimum. Server Compass currently labels its Overseerr template as 512 MB+ RAM, but that is third-party guidance rather than an upstream requirement. Size production hosts for Overseerr plus Plex, Sonarr, Radarr and other co-hosted services.
Is Overseerr still actively developed in 2026?
No as a standalone mainline project. The official Overseerr repository says it is being superseded by Seerr and will no longer receive new features or major updates. The Seerr team announced the Overseerr/Jellyseerr unification on February 10, 2026.
Should I install Overseerr or Seerr on a new ZimaOS server?
For a new long-term deployment, use Seerr. ZimaOS still lists Overseerr, but upstream recommends migrating to Seerr for continued support and development.
Can ZimaBoard 2 832 run Overseerr?
Yes. Its Intel N150, 8 GB RAM and dual 2.5GbE provide far more host headroom than the third-party 512 MB+ Overseerr template guidance. The limiting factor is more likely to be the other media applications sharing the server.
Does Overseerr need a GPU?
No. Overseerr is a request-management and discovery frontend; it does not transcode media. A GPU is relevant only if Plex/Jellyfin, AI or another co-hosted application needs it.
Does Overseerr store my movies and TV shows?
No. Overseerr stores application data such as configuration, users, requests and integration state, while Plex and the underlying NAS/media paths hold the actual library.
Can I migrate existing Overseerr data to Seerr?
Yes. The official Seerr migration guide says Seerr can automatically migrate existing Overseerr data on first startup. Keep the old appdata intact until the new Seerr instance has been tested and verified.
Are the Overseer Network Monitor and docs.overseer.sh hardware requirements relevant?
No. They are different products with similar names. Overseer Network Monitor is Windows monitoring software, while docs.overseer.sh describes a separate automation/chat/files/bot platform. Their CPU and RAM figures must not be used for the media request manager Overseerr.
What sources and further reading informed this Overseerr hardware guide?
The official Overseerr repository establishes the current superseded status and migration recommendation. The Seerr release and migration documentation establish the 2026 project merger and migration path. LinuxServer confirms its Overseerr image is deprecated. Server Compass supplies only third-party 512 MB+ deployment guidance. The two similarly named Overseer sources were explicitly excluded as different products. Current ZimaOS and Zima product pages were used to verify app availability and hardware specifications.
