Nostrss is a lightweight, open source bridge that broadcasts RSS feeds to the Nostr protocol. It suits bloggers, news sites and community curators who want new articles to reach Nostr users without manual reposting. The project is written in Rust and released under the MIT license, so it is free to download, use and study.
The current release is v1.1.0, and the code was last updated on March 12, 2026, so the project is active as of this page. Nostrss is not a Nostr client: you won't use it to read timelines or chat. Its job is one-directional, taking items from a feed and publishing them as Nostr events. The project does not publish an official Windows build, so Nostrss for Windows users should check the Releases page and build notes before installing.
What Is RSS-to-Nostr Broadcasting?
RSS is a long-standing format that lets websites publish a machine-readable list of their latest items. Feed readers and automation tools check these lists to learn when something new appears. Nostr, short for Notes and Other Stuff Transmitted by Relays, is an open protocol in which users publish signed events to relays, and clients subscribe to the events they want.
A bridge like Nostrss sits between these two systems. It watches a feed, notices new entries and turns them into Nostr events. Once those events reach relays, any Nostr client that follows the publishing identity can display them. A blog or newsroom can reach Nostr users without anyone copying links by hand.
The model is one-way. Readers do not read through Nostrss; they see the posts in whatever client they already use. That separation keeps the bridge simple and lets you choose your own reading app.
Who Should Consider Nostrss?
Nostrss fits people who already publish regularly on the web and want that output to appear on Nostr. A personal blogger might use it to share each new post with a Nostr audience. A small news site could route its headlines there while keeping the website as the main home for stories.
Community curators are another natural audience. Someone who follows several sources on a niche topic can publish those updates under a single Nostr identity, giving followers one stream to follow. Developers who maintain changelogs or release notes may find that a feed-based workflow saves them from posting the same update twice.
It is less suited to people who mainly want to read, chat or browse. For those needs, a full client will serve better. Nostrss rewards users who are comfortable managing their own Nostr keys and checking that the output looks right on relays.
Key features
Lightweight by design
Flexible feed handling
RSS to Nostr broadcasting
Open source under MIT
Supported coins
The only network named in the project documentation is Nostr itself. Nostrss is a publishing bridge for social content rather than a cryptocurrency tool, so there is no coin or wallet list to review. Its role is to carry RSS items onto the Nostr protocol, where compatible clients can display them.
How to install Nostrss on Windows
- 1
Get the files from official sources
Download only from the official sources: the project's GitHub repository at github.com/Asone/nostrss and its Releases page. The Releases page lists published versions, including the latest v1.1.0, along with any attached files.
- 2
Check for a Windows build
The project notes that it does not ship an official Windows release because specific configurations are needed. If the Releases page has no Windows file, you will need to build from source following the repository instructions. Building requires developer tools such as the Rust toolchain, but those are needed only for this step.
- 3
Verify the download
Compare the file's SHA-256 checksum with the value published alongside the release, or check its signature if one is provided. Do not run any file whose checksum does not match.
-
Install and run
Place the program in a folder of your choice, such as a dedicated directory in your user profile. Launch it from a terminal window so you can read any startup messages, and confirm it runs before you connect any Nostr keys.
System requirements
- Windows: no official prebuilt release is published, so the program may need to be built from source using the project's own instructions
How to use Nostrss
Nostrss runs as a bridge, so setup means connecting one feed to one Nostr identity. Start with a single feed to keep testing simple.
- Choose the RSS feed you want to publish and confirm its URL loads in a browser.
- Prepare the Nostr key you plan to publish with, and store it somewhere secure.
- Set up the relays where posts should go, and check the project README for the expected configuration format.
- Start Nostrss from a terminal and watch the output for newly detected entries.
- Open the same Nostr identity in a client such as Gossip to confirm the posts appear.
- Review the results over several cycles before adding more feeds.
Pros & cons
- Free to use and licensed under MIT
- Lightweight, single-purpose design
- Written in Rust
- Public source code on GitHub
- Recent update: v1.1.0 with code changes in March 2026
- Clear role as a one-way RSS to Nostr bridge
- No official Windows or macOS release, so many users will need to build from source
- Publishing only, with no reading or messaging interface
- Requires comfort with Nostr keys and relay settings
- Only the Nostr protocol is named as a supported network
- Narrow scope means no built-in client features
Is Nostrss safe?
Nostrss is open source under the MIT license, so you can inspect the code on GitHub before running it. Download only from the official GitHub repository or its Releases page, and avoid copies from third-party download sites that may be repackaged. Check the SHA-256 checksum or signature against the values published with the release, and skip any build that fails verification.
Because the bridge publishes under a Nostr identity, your private key is the sensitive part. Never paste a private key into a third-party website or chat, and keep it in a secure location with limited access. Treat any tool that asks for it with the same caution you would give a wallet seed phrase.
The project has no official Windows release, so any build you create is your own responsibility to verify. Check the latest version on the official website before updating.
- Official source only. Download from github.com/Asone/nostrss. 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
Nostrss sits in a different spot from most Nostr tools in this catalog. Amethyst, Coop, Gossip and Vega are clients: you use them to read, post and talk with people on Nostr. Nostrss has no reading interface and does not replace that role. It takes an RSS feed and publishes it automatically, which is closer to automation than to social apps.
NAK and Nostr Commander RS are command-line tools. They suit users who prefer scripting and manual control, while Nostrss is built around one feed-to-relay job. Nostr VPN and Blockcore Notes serve different purposes entirely, as a mesh VPN control plane and a progressive web app for following circles.
If you need feed publishing, Nostrss is the focused choice. If you want a full social experience, pair a client from this list with it.

Frequently asked questions
Yes, Nostrss is free. It is open source under the MIT license, which permits use, modification and redistribution. You do not pay to download the code or run the program. The license and source code are available in the GitHub repository, so you can read the terms yourself before using it personally or commercially.
No official Windows release is published, because the project says specific configurations are required. Start by checking the GitHub Releases page for a Windows file. If none is listed, build the program from source using the repository instructions, and verify your result before running it.
It can be, provided you take normal precautions. The code is open under the MIT license, so it can be inspected. Download it only from official GitHub sources, check the SHA-256 checksum or signature when one is available, and keep your Nostr private key away from third-party websites.
Nostrss takes items from an RSS feed and broadcasts them to the Nostr protocol as events. It acts as a bridge, not a reader. Readers then see those posts in any Nostr client that follows the publishing identity, so the tool serves publishers who want their feed updates to reach Nostr users.
macOS is listed among the platforms, but the project also notes there is no official macOS release. Mac users would likely need to build the program from source, following the repository instructions. The same checks apply: review the source, compare checksums where available, and keep private keys secure.
Yes, the project shows recent activity. The latest version is v1.1.0, and the code was last updated on March 12, 2026. Regular updates are a good sign, but review the release notes before upgrading and confirm the current version on the GitHub Releases page.
A Nostr client lets you read, write and follow people. Nostrss only publishes. It takes entries from an RSS feed and sends them to Nostr relays, so you cannot browse timelines with it. For reading, pair the bridge with a client such as Gossip or Amethyst.
Verdict
Nostrss is a focused, free and MIT-licensed bridge for publishing RSS feeds to Nostr. It suits bloggers, newsrooms and curators who want their updates to reach Nostr users automatically, as well as developers comfortable with Rust-based tools. The lack of an official Windows release is the main hurdle, so plan for a build from source unless the Releases page offers a file you can verify. If you mainly want to read or chat on Nostr, choose a client instead and keep Nostrss as a companion for publishing.
