Cloud Seeder is a Windows-friendly deployment tool for people who want to run Nostr infrastructure without building every server component by hand. It is aimed at self-hosters and hobbyists who would rather manage a relay or similar service through a guided interface than through a terminal and a stack of configuration files.
The project comes from IPv6rs and is released as open-source software at no cost. Its main job is to package services into ready-to-run appliances, so you can install, start, and manage them from one place. If you are curious about running your own Nostr relay on a Windows machine, it is a practical place to start.
What Is Cloud Seeder and How Does It Work?
Cloud Seeder is best understood as a wizard for server appliances. Rather than asking you to configure a service from scratch, it presents a set of prepared appliances and deploys the one you select. The underlying idea is that each service should be packaged as a complete unit, carrying everything it needs to run.
This approach follows a deliberate philosophy. Instead of spreading one application across many shared components, the tool places each appliance inside its own container. The result is a self-contained system that is easier to start, stop, and remove without affecting other services running on the same machine.
Who Is Cloud Seeder For?
The program is most useful for people who want to run Nostr infrastructure themselves but do not want to become system administrators first. Typical readers include:
- Individuals who want a personal relay for their own notes and follows
- Small community groups hosting a relay for members
- Developers testing Nostr services on a local Windows machine before moving to a server
- Hobbyists who enjoy self-hosting and want to keep a tidy, reproducible setup
If you only want to read and post on Nostr, a client app is a simpler choice. Cloud Seeder is for the next step, where you host the infrastructure behind the network.
Why Fat Containers Save Resources
A common frustration with containers is that each one can demand a fixed slice of memory and processor time, even when it is idle. Multiply that across several services and a modest computer quickly runs out of room. Cloud Seeder's design addresses this by not reserving a fixed amount of RAM and CPU for each appliance in advance.
In practice, this means you can keep several appliances running alongside one another. For someone experimenting with different services, that flexibility can be the difference between running one tool at a time and running a small, working collection.
Permissions and Security Trade-offs
Running containers with elevated access is never a neutral decision. Cloud Seeder notes that its setup needs specific permissions, including network administration capability, access to the tun network device, and read-only access to cgroups. Those are reasonable requirements for a tool that manages networking and isolation, but they also widen what a misbehaving or compromised appliance could touch.
The project's own documentation points out that one appliance, bluesky, requires privileged access. That detail deserves attention. Treat any appliance with extra privileges as something to run only after you have decided you trust its source and purpose.
Nostr Relays in Plain Language
Nostr is a decentralized protocol in which messages are passed through relays rather than a single company's servers. A relay stores and forwards events, and anyone can run one. Hosting your own relay gives you control over what it keeps and how it behaves, though it also means you are responsible for uptime, storage, and moderation of the content it receives.
Before committing to a self-hosted relay, consider whether you need a relay that is always online, how much storage you expect to use over time, and whether you are comfortable answering for the content your server carries.

Check the SHA-256 checksum or signature of the downloaded installer against the value published with the release. If the values do not match, do not run the file and download it again from the official source.
- 3
Run the installer
Launch the installer and follow the on-screen prompts. Windows may show a security prompt for an unfamiliar publisher; confirm that the file came from the official Releases page before continuing.
-
Start the application
Once installed, open Cloud Seeder from the Start menu. The first launch lets you choose an appliance to deploy, and the wizard guides you through the remaining steps.
System requirements
- Windows 10 or Windows 11
- x86 (32-bit) architecture
How to use Cloud Seeder
Cloud Seeder is designed to keep the first deployment simple. The steps below describe a typical path from launch to a running appliance.
Before you begin, decide which appliance you want and confirm that you trust it, especially if it needs elevated access.
- Open Cloud Seeder and review the list of available appliances.
- Select the appliance you want, such as nostr-rs-relay for a Nostr relay.
- Read any permission notes shown for that appliance and confirm you are comfortable granting them.
- Follow the wizard to set basic options, such as the network port the service should use.
- Start the deployment and wait for the appliance to report that it is running.
- Check that the service responds locally before opening it to other machines or the internet.
- Use the management view to stop, restart, or remove the appliance when you no longer need it.
Pros & cons
- Free and open source, with the code publicly available
- Guided, one-click deployment reduces setup effort
- Appliances are isolated from one another and from the host system
- Does not require reserving fixed RAM and CPU per appliance, allowing more services on one machine
- Official builds cover Windows, macOS, and Linux
- Requires elevated network and container permissions
- Some appliances, such as bluesky, need privileged access that calls for extra caution
- Windows support is limited to x86 builds, which may matter on newer hardware
- Running a public relay carries ongoing responsibility for uptime and content
Is Cloud Seeder safe?
Cloud Seeder asks for network and container permissions, so treat its installation with the same care you would give any system-level tool. Download only from the official GitHub Releases page, and verify the SHA-256 checksum or signature before running the installer. Never enter a seed phrase, password, or private key on a third-party website that claims to offer this software.
Review the permissions each appliance requests before deploying it. Appliances with privileged access should only run if you trust their source and understand what they can do. Keep the tool and its appliances updated, and remove any appliance you no longer use so it does not keep running with access you no longer need.
- Official source only. Download from github.com/ipv6rslimited/cloudseeder. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Cloud Seeder sits in a different place from most programs in this category. Clients such as Amethyst, Coop, Gossip, and Vega are for reading and posting on Nostr, while Cloud Seeder is for hosting the infrastructure that such clients connect to. If you want a desktop experience for everyday use, a client is the right tool. If you want to run a relay yourself, Cloud Seeder addresses that need directly.
Command-line tools like NAK and Nostr Commander RS also serve experienced users, but they are oriented toward scripting and interaction rather than guided server deployment. Nostr VPN, by contrast, focuses on networking between machines. Choosing among them depends on whether your goal is to use Nostr, host it, or connect devices securely.
