To install and run Tiny Tiny RSS (tt-rss), you need two things: a modern web browser (a recent version of Chrome/Chromium or Firefox) and a system running Docker. The official Installation Guide covers the detailed steps. If you choose to run tt-rss without Docker, support may be limited. Because tt-rss follows a continuous development model based on the main branch (which is considered stable), it's strongly recommended that you stay current — using either the most recent Docker image(s) or the latest commit on main.

Prerequisites at a Glance

Why Docker Is the Recommended Path

tt-rss is a self-hosted, web-based RSS/Atom reader and aggregator, so it runs as a service you access through a browser rather than as a desktop application. The project's installation guidance assumes Docker as the standard deployment method. Running it outside Docker is not forbidden, but the documentation notes that support may be limited in that case — meaning you take on more of the troubleshooting yourself.

Staying Current

tt-rss uses a continuous development model based on the main branch, which the project treats as stable. There are no traditional versioned releases to wait for. In practice, this means:

• Pull the most recent Docker image(s), or
• Track the latest commit on main

Staying current is strongly recommended rather than optional, since fixes and changes land on main continuously.

What You Get Once It's Running

For context on what the setup delivers, tt-rss is free software licensed under GNU GPLv3 and is self-hosted, so you control your own data instead of relying on third-party services. Documented features include organizing feeds by folders and subfolders, feed aggregation and syndication, keyboard shortcuts, OPML import/export, multiple sharing methods (exported RSS feeds, plugins for social sites, sharing by URL, and sharing arbitrary content through tt-rss), plugins and themes, full article embedding via readability and site-specific plugins, deduplication (including perceptual hashing for images), podcasts, flexible article filtering, and a JSON API.

The tt-rss software is licensed under GNU GPLv3; the documentation is licensed under CC BY-SA 4.0.

An open-source UI element library is a collection of individual, ready-made interface pieces—buttons, cards, inputs, toggles, loaders—that you copy into your own project and adapt. A UI framework, by contrast, is a structured system of components, conventions, and often a theming layer that governs how your whole interface is built. The practical difference: an element library gives you a snippet; a framework gives you a way of working. If you need a polished button in ten minutes, reach for the element library. If you're building a 40-screen product with a team, you probably want the framework.

What "open-source UI element library" actually means

The term gets used loosely, so it helps to separate the parts:

• Open-source: the code is publicly available, and the license tells you what you may do with it—copy, modify, redistribute, or use commercially.
• UI element: a single, self-contained piece of interface, usually small enough to read in one sitting. A button with hover states, a pricing card, a search field.
• Library: a browsable, searchable collection of those elements, typically contributed by many different people.

On a site like Uiverse, elements are shared by a community and written in plain CSS or Tailwind. You find one you like, copy the markup and styles, paste them into your project, and adjust colors, spacing, and text to fit. There's no package to install and no build step required—which is exactly the appeal, and also the source of most of the confusion.

Element library vs. UI framework: the core differences

The table isn't a verdict. It's a map of trade-offs. Element libraries win on speed and freedom; frameworks win on consistency and maintenance.

Licensing and attribution: what to check before you paste

This is where people get into trouble, and it's worth slowing down for.

1. Find the license. Every element or collection should state one. Common open-source licenses include MIT, Apache-2.0, and BSD. Some projects use copyleft licenses like GPL, which can impose obligations if you redistribute your code.
2. Understand what the license permits. MIT and Apache-2.0 are permissive: you can typically use the code in commercial and closed-source projects. Copyleft licenses may require you to release derivative source under the same terms.
3. Check attribution requirements. Permissive licenses usually require you to keep the copyright notice and license text somewhere in your project. That's a real obligation, not a formality.
4. Look for per-element terms. On community sites, the site's overall terms and the individual contributor's stated wishes may differ. If a contributor asks for credit, honor it.
5. When in doubt, ask or avoid. If a snippet has no license at all, you don't have clear permission to reuse it. Treat "no license" as "not open source," even if the code is publicly visible.

This article is general information, not legal advice. For commercial products with real exposure, have someone qualified review the licenses you're relying on.

How to use a community element in your project: a practical workflow

Here's a repeatable process that avoids most of the usual mess.

1. Start from a real need, not a browsing session

Decide what you need first—"a compact primary button with a loading state"—then search. Browsing aimlessly produces a pile of pretty snippets that don't fit together.

2. Copy the smallest version that works

Take the markup and the styles. Strip anything you don't need: demo wrappers, extra animations, decorative layers. Less code means fewer surprises.

3. Convert it to your conventions

If your project uses design tokens or CSS variables, replace hard-coded values:

/* Before: hard-coded */
.button { background: #4f46e5; border-radius: 8px; }

/* After: token-based */
.button { background: var(--color-primary); border-radius: var(--radius-md); }

This one step is what keeps a copied element from looking like a foreign object in your UI.

4. Check accessibility before you ship

Community elements vary widely here. Verify at minimum:

• Keyboard focus is visible and the element is reachable by Tab.
• Color contrast meets WCAG AA (4.5:1 for normal text).
• Interactive elements use semantic HTML (<button>, not a clickable <div>).
• Form inputs have associated labels.
• Motion respects prefers-reduced-motion.

5. Test in context

Paste it into a real page with real content. Long labels, small screens, and dark mode break more copied elements than anything else.

6. Note where it came from

Keep a short comment or an internal credits file: source, license, date. Future you—and your legal reviewer—will be grateful.

Where element libraries genuinely shine

• Prototypes and demos: you need something clickable today, not a design system.
• Landing pages and marketing sites: a handful of distinctive elements, each custom.
• Filling gaps: your framework lacks one specific component, and you don't want to build it from scratch.
• Learning: reading well-made CSS is one of the fastest ways to improve.
• Small projects: a personal site doesn't need a theming architecture.

Where they fall short

• Consistency at scale: ten elements from ten contributors rarely look like one product.
• Maintenance: you own every copy. When your design changes, you edit each one.
• Accessibility debt: you inherit whatever the contributor did or didn't do.
• No upstream fixes: a bug fixed in the original won't reach your copy.
• Integration friction: different naming conventions, different units, different assumptions about resets.

When to choose which

Choose an element library when the scope is small, the timeline is short, or you need a few distinctive pieces rather than a whole system.

Choose a framework or design system when multiple people build multiple screens over months, when consistency is a product requirement, or when accessibility and theming need to be guaranteed rather than checked.

A hybrid works well for many teams: adopt a framework for the structural components—forms, navigation, layout—and borrow individual elements for the places where you want personality. Just route every borrowed element through the same token and accessibility checks, so it lands as part of your system rather than beside it.

The short version: open-source UI element libraries are a fast, flexible way to get good-looking interface pieces into a project. They are not a substitute for a design system, and the license and accessibility details are the part worth reading carefully.

For Tiny Tiny RSS (tt-rss), the official support and contribution channels all live on GitHub. If you have a question or want to discuss something, go to the tt-rss Discussions. If you want to report a bug or request a feature, use the tt-rss Issues. If you want to contribute code, translations, or other improvements, read CONTRIBUTING.md first.

Which channel should you use?

The right destination depends on what you're trying to do:

The split is deliberate: Discussions is for open-ended conversation, while Issues is for concrete, trackable problems and feature requests. Posting a question in Issues or a bug report in Discussions makes it harder for maintainers to follow up.

Before you post

tt-rss uses a continuous development model based on the main branch, which is considered stable. The project strongly recommends staying current — either by using the most recent Docker image(s) or the latest commit on main. If you're running an older version, you may be asked to update before your issue can be addressed, since the problem may already be fixed.

Installation itself requires a modern web browser (a recent version of Chrome/Chromium or Firefox) and a system running Docker. The project notes that if you run tt-rss without Docker, support might be limited — worth keeping in mind if you hit a setup problem and plan to ask about it.

Contributing

Contributions are welcome in several forms: code, translations, and reporting issues. The CONTRIBUTING.md file is the starting point and explains how to take part.

Licensing

Two licenses apply, and they cover different things:

• The tt-rss software is licensed under GNU GPLv3.
• The documentation is licensed under CC BY-SA 4.0.

If you plan to reuse, modify, or redistribute either, check the corresponding license terms before doing so.

Tiny Tiny RSS (tt-rss) is described that way because the software runs on a system you control rather than on a vendor's servers. The project's own description states it is "self-hosted: control your own data and protect your privacy instead of relying on third party services." In practice, that means your feed subscriptions, read/unread state, and saved articles live in your own instance, and no external RSS service holds that reading history. The trade-off is that you are responsible for running and maintaining that instance.

What "self-hosted" actually means here

Self-hosting is an architectural choice, not a privacy policy. With tt-rss, the application, its database, and your feed data all run on infrastructure you provide. The project lists Docker as the supported way to run it:

• You need a modern web browser (a recent Chrome/Chromium or Firefox).
• You need a system running Docker.
• The project points to its Installation Guide for detailed instructions.
• Running tt-rss without Docker is possible, but the project warns that "support might be limited."

Because the instance is yours, the data flow is different from a hosted reader. When you subscribe to a feed, your server fetches it and stores the content locally. Your reading behavior — what you open, what you mark read, what you star — is recorded in your own database rather than on a third party's analytics backend.

Why that is framed as privacy-focused

The privacy claim follows directly from the architecture. If a third-party service hosts your reader, that service can see your subscription list and reading patterns. With a self-hosted tt-rss instance, that information stays on your machine or server. The project's framing is explicit: control your own data instead of relying on third party services.

Two supporting facts from the project reinforce this:

• It is free software under GNU GPLv3. You can inspect, modify, and run the code, so the privacy behavior is not a black box.
• It is a continuous development model based on the main branch, which the project considers stable. It strongly recommends staying current, using either the most recent Docker image(s) or the latest commit on main.

That last point matters for privacy in a practical sense: because you run the software, keeping it updated is your responsibility, and the project treats staying current as the expected mode of operation.

What you control, and what you take on

The page does not state pricing, so no assumption should be made that running it is free of infrastructure cost — you still provide the system it runs on.

Features that support the self-hosted model

The feature list is built around owning your reading experience rather than depending on a platform:

• Organizing feeds by folders and subfolders
• Feed aggregation and syndication
• OPML import/export, so you can move your subscription list in and out
• Multiple sharing options: exporting RSS feeds, plugins for social sites, sharing by URL, and sharing arbitrary content through tt-rss
• Plugins and themes
• Embedding full article content via readability and site-specific plugins
• Deduplication, including perceptual hashing for images
• Podcasts
• Flexible article filtering
• A JSON API

OPML export and the JSON API are the practical escape hatches: your data is portable, which is consistent with the "control your own data" claim.

The practical bottom line

tt-rss is self-hosted and privacy-focused in the literal sense: you run it, you hold the data, and the source is open for inspection. If your priority is keeping your reading habits off third-party servers and you are willing to run a Docker-based service and keep it updated, the model fits. If you would rather not maintain a server, the self-hosted design is a cost rather than a benefit — that is the condition to weigh before choosing it.

Tiny Tiny RSS (tt-rss) is a free, open-source, web-based RSS/Atom feed reader and aggregator, and tt-rss.org is its official project site. It is for people who want to read and organize feeds on a server they control rather than through a third-party hosted service. The site itself is a landing page: it introduces the software, lists features, shows screenshots, links to installation instructions, and points to community and development channels.

What the software does

At its core, tt-rss collects feeds and presents them in a web interface. The project describes it as a "free, flexible, open-source, web-based news feed (RSS/Atom/other) reader and aggregator."

Key capabilities listed on the site include:

• Self-hosting — you run it yourself, so you "control your own data and protect your privacy instead of relying on third party services."
• Feed organization — organize feeds by folders and subfolders.
• Aggregation and syndication — combine and redistribute feeds.
• Keyboard shortcuts — navigate and act without a mouse.
• OPML import/export — move feed subscriptions in and out.
• Multiple sharing methods — export RSS feeds, use plugins for various social sites, or share by URL.
• Sharing arbitrary content — push non-feed content through tt-rss.
• Plugins and themes — extend and restyle the interface.
• Full article embedding — pull in complete article content via readability and site-specific plugins.
• Deduplication — including perceptual hashing for images.
• Podcasts — handle audio feeds.
• Flexible article filtering — rules to decide what you see.
• JSON API — programmatic access for clients and integrations.

The site notes there is "much more," so the list above is not exhaustive.

Licensing and cost

tt-rss is free software licensed under GNU GPLv3. The site describes it as "free, flexible, open-source." The available page material does not list prices or paid tiers, so no pricing conclusion should be drawn beyond the open-source license.

How it is installed and run

According to the site, installation requires:

1. A modern web browser — generally a recent version of Chrome/Chromium or Firefox.
2. A system running Docker — the Installation Guide provides detailed instructions.

Two important operational notes from the project:

• If you run tt-rss without Docker, "support might be limited."
• tt-rss uses a continuous development model based on the main branch, which is considered stable. The project "strongly recommends" staying current — using either the most recent Docker image(s) or the latest commit on main.

Who it is for

tt-rss fits you if you want a self-hosted feed reader, are comfortable running Docker, and prefer open-source software you can inspect and extend. It is less suited if you want a zero-setup hosted reader or cannot run a server or Docker environment, since the project ties its recommended path to Docker and continuous updates.
