Camelus is an open-source Nostr client for people who want a straightforward way to post, read, and interact on decentralized social networks. It suits everyday users who would rather not wrestle with complicated settings, as well as people curious about Nostr who want an approachable first client. The app is built with Dart and Flutter, and the current release is v1.10.1.
Unlike conventional social networks that keep content on a single company's servers, Camelus relies on the Nostr protocol for decentralized data storage. The project presents this design as a privacy improvement for users who share posts and engage with others. Because the project describes itself as a mobile app, check which Windows package is offered before you install.
What Is Camelus and Where Does It Fit?
Camelus is a client, meaning the app you use to write and read messages. It does not host your posts itself. Instead, it connects to relays, which are servers that store and pass along Nostr events.
This separation is the key idea behind Nostr. Your identity is a cryptographic key pair rather than a username tied to one platform, and any compatible client can display the same content. If you later decide to switch apps, your identity and the events you published can still be used elsewhere.
Camelus sits among other Nostr clients, from mobile apps to desktop programs and command-line tools. Its focus is on approachability, so it is a reasonable starting point for people who want to see how Nostr works without dealing with technical setup.
Who Camelus Is For
Camelus fits several types of readers. The first group is people who have grown tired of centralized feeds and want more control over where their posts live. Because the app emphasizes simplicity, it can also help someone who is curious about decentralized networks but unsure where to begin.
The second group is privacy-minded users. They may appreciate that the project frames Nostr as a way to reduce dependence on a single provider. Keep in mind that privacy depends on your habits as well, including what you post publicly and how you manage your keys.
A third group includes developers and hobbyists who want to study an open-source client built with Flutter. Because the code is public on GitHub, anyone can read how the app is structured, report issues, or contribute improvements.
How Nostr Keys and Relays Work Together
Every Nostr user has a private key and a matching public key. The public key works like an address others use to find you, while the private key signs your messages to prove they came from you. Losing the private key means losing control of that identity, so it deserves careful handling.
Relays are the second half of the system. A relay receives signed events from clients and makes them available to others. Users can generally choose which relays to connect to, which gives them flexibility if one server becomes slow or stops accepting content.
For a newcomer, the practical lesson is simple: your identity belongs to you, but your experience depends on the relays you use. Choosing reliable relays can make a noticeable difference in how quickly posts load and how consistently your feed updates.
Key features
Simplicity First
Decentralized Storage on Nostr
Privacy-Oriented Architecture
Supported coins
Camelus is built around the Nostr protocol, and that is the only network it is associated with. It is a social client rather than a wallet or exchange, so it does not hold, send, or trade cryptocurrency. Its role is to publish and display signed messages on Nostr.
How to install Camelus on Windows
- 1
Get the Official Build
Download Camelus from the official website or from the project's GitHub Releases page at github.com/camelus-hq/camelus. Choose the Windows build or installer, and avoid copies offered by unrelated sites.
- 2
Verify the File
Compare the SHA-256 checksum of the downloaded file with the value published on the release page. If a signature is provided, check it as well before you run the file.
-
Install and Launch
Run the installer and follow the on-screen prompts, or extract the build to a folder you control. Start Camelus, then either create a new Nostr key or import an existing one.
How to use Camelus
Camelus is designed to get you posting quickly, but a few preparation steps make the first session smoother. Start by deciding whether you want a brand-new identity or to reuse an existing Nostr key, since that choice affects your public profile.
- Open Camelus and set up your identity by creating a new key pair or importing one you already use.
- Back up your private key in a password manager or other secure, offline location before you publish anything.
- Connect to a few relays, choosing ones that you trust and that other users in your circle already rely on.
- Write a short profile so people can recognize you, and avoid including personal details you would not share publicly.
- Follow a handful of accounts, then check your feed over several days to see how the relays you chose perform.
Take your time with the first few posts. Nostr events are signed and distributed, so treat each message as something that may be stored and shared beyond your immediate audience.
Pros & cons
- Focuses on simplicity and usability, which suits newcomers
- Free and open source, with the code publicly available on GitHub
- Uses the Nostr protocol for decentralized data storage
- Built with Flutter, offering a consistent codebase
- Positioned as a privacy-friendly alternative to centralized networks
- The project describes itself as a mobile app, so the Windows experience may differ from the Android version
- Nostr concepts such as keys and relays take time to understand
- Your experience depends on the relays you choose
- Fewer built-in options for power users compared with some desktop clients
Is Camelus safe?
Camelus is free and open source, which lets you inspect the code, but you should still obtain it carefully. Download only from the official website or the project's GitHub Releases page, and verify the SHA-256 checksum or signature before running the installer. Files from third-party sites can be altered, and a modified app could expose your private key.
Never enter your Nostr private key into a third-party website, browser extension, or service that asks you to "verify" your account. Anyone who obtains that key can impersonate you. Keep the key backed up offline, and remember that the latest version is always listed on the official site.
- Official source only. Download from github.com/camelus-hq/camelus. 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
Camelus shares its core purpose with other Nostr clients, but its main emphasis is simplicity. Amethyst is a Nostr client focused on Android, which makes it a natural comparison for mobile users. Gossip is a desktop client written in Rust, so it suits people who prefer a more technical environment on their computer. Coop focuses on private messaging over Nostr, while Camelus aims at general social posting and browsing.
For a Windows user who wants a gentle introduction, Camelus is a reasonable starting point. If you need advanced desktop features or command-line workflows, options such as Gossip, Vega, or NAK may fit better. Compare two or three clients before settling on one.

Frequently asked questions
Yes, Camelus is free and open source. The code is published on GitHub, so anyone can review how it works. Because there is no purchase required, you can try it without paying, though you should still download it only from official sources.
Camelus is offered as a Windows build or installer, though the project also describes itself as a mobile app and lists Android among its platforms. Check the official website or GitHub Releases page for the current Windows package before you install it on your computer.
Nostr is an open protocol for decentralized social communication. Users sign their messages with a private key and publish them to relays, which store and share the events. Because no single company controls the network, clients like Camelus can display content from many sources.
Camelus can be used safely when you download it from the official website or GitHub, verify its SHA-256 checksum, and keep your private key secret. Avoid entering your key on third-party sites. Most risk comes from how you handle keys and files rather than from the app itself.
You need a Nostr identity, which is a key pair, rather than an account registered with a company. You can create one inside the app or import an existing key. Back up the private key carefully, since losing it means losing access to that identity.
Traditional networks store posts on company servers and control the feed. Camelus uses Nostr, so content is distributed across relays and your identity is not tied to one platform. That makes it more flexible, but it also means you manage your own keys and relay choices.
Amethyst, Gossip, Coop, and Vega are common alternatives to explore. Amethyst suits mobile users, Gossip and Vega are desktop-oriented, and Coop focuses on private messages. Trying two or three clients will help you find the one that matches your habits.
Verdict
Camelus is a good fit for people who want an approachable introduction to Nostr and a clean, uncluttered client. It suits users who value decentralized storage and a privacy-minded design, as well as developers curious about a Flutter-based open-source project. It is free and its source code is public.
If you need advanced desktop tools or a command-line workflow, compare it with alternatives first. Before you commit, confirm that the Windows package meets your needs and review the safety steps above.
