Fusion

Fusion is a small, fast RSS and Atom reader. Paste a site address and it finds the feed for you, sorts your subscriptions into groups, and gets out of the way. Unread counts, bookmarks, full-text search and Google Reader style keyboard shortcuts are the whole feature list, and that's deliberate: the project ships no AI features on purpose.

The web interface is responsive and installs as a progressive web app, so it works on a phone as well as it does on a laptop. It speaks eight languages out of the box.

When does Fusion make sense?

  • You read a lot of feeds and want the reading part to be quick. Keyboard shortcuts, unread tracking, done.
  • You want a reader on your phone. Fusion's Fever endpoint works with apps like Reeder, Unread and FeedMe.
  • You want something smaller than a full reader platform. For multi-user accounts and filters, FreshRSS and Miniflux are the bigger options.
  • A site you follow has no feed? Point RSSBridge at it and subscribe to the result.

How do I access Fusion?

Fusion is available:

Signed-in users see their own URLs

The addresses above show the general pattern. Sign in and these become your personal, clickable links.

How do I use it?

Signing in: you'll do it twice

Fusion sits behind your ElfHosted login, and it also has a password of its own. Both are needed the first time you open it in a browser.

Your Fusion password is generated when the app first starts and saved as .fusion_password in your config/fusion folder. Open that file with FileBrowser to read it.

Prefer to pick your own? Set it with ElfBot, and Fusion restarts to use it:

Quick-paste into Fusion's environment variables using ElfBot
FUSION_PASSWORD=something-you-will-remember

Once you set FUSION_PASSWORD this way, that's the password, and the generated one is no longer used. Fusion has no username field, and no other accounts.

Add some feeds

  1. Click Add feed and paste either the feed address or the site's home page. Fusion discovers the feed from the page for you.
  2. Put feeds into groups to keep work, news and hobbies apart.
  3. Press ? anywhere in the reader for the keyboard shortcut list.
  4. Bookmark anything you want to keep, and search across everything from the top bar.

Feeds published on private network addresses aren't reachable, so a feed on your own LAN won't load. Public feed addresses are fine.

Read on your phone with a Fever client

Fusion speaks the Fever API, and that one endpoint is reachable without your ElfHosted login, because mobile feed apps can't sign in through it. Fusion checks the credentials itself.

In your feed app, choose Fever as the account type and enter:

Field Value
Server / endpoint https://your-username-fusion.elfhosted.com/fever
Username fusion
Password Your Fusion password

Fever clients turn that pair into an API key, the MD5 of fusion:<your password>, and send it with every request. That means your Fusion password is the key to the endpoint, so pick a good one and keep it to yourself. Change the password and every Fever client needs the new one.

The rest of Fusion, including the web interface, stays behind your ElfHosted login.

Where are my feeds stored?

Fusion keeps subscriptions and articles in a SQLite database in your config/fusion folder, and we back it up daily. Fusion sends no email, so there's nothing to configure for notifications.

What users say..

We're rocking some excellent ⭐⭐⭐⭐⭐ TrustPilot Reviews, and here's what some of our usersfriends say..

I am new here, but today I learned realized that Elfhosted is one of the best free and open source software communities I've seen, and FOSS communities have been at the center of my life since the 90s (Perl, PHP, Symfony, Drupal, Ethereum, etc.). Great open software built by great people who care = great community, and that is something special.

You've done an amazing job @Funky Penguelf with the platform you provide and this place has an awesome mix of active community caretakers and software creators that I've seen here so far like BSM, Spoked, LayeZee and other elf vengers. Keep up the energy, productivity and community and take time to enjoy it and appreciate each other!

As a happy Elfhosted customer—who also self hosts MANY things across about 10 severs (dedicated, VPSes, and VMs running on Synology), I wouldn’t switch to self hosting the services I get from Elfhosted. They just work with very little effort configuring things, and the support the owner and his team provides is second to none. Plus I love being part of a fledgling—but quickly growing—enterprise.

⭐⭐⭐⭐⭐ /u/jatguy. (Reddit)

I’ve been using this service for a while now, and honestly, it’s a game-changer compared to anything else I’ve tried for managing my media library. The support is fantastic—super quick, and if the staff aren’t around (which rarely happens), the community steps up right away. I can’t imagine going back to any other platform.

Before this, I had my own setup with a NUC, NAS, and tools like Sonarr and Radarr. It worked pretty well for a while, and my internet speed was high enough to stream without any buffering. But in the end, it wasn’t worth the time or headache of managing all the storage and keeping everything running smoothly.

Now, with this service, everything runs smoothly in 1080p+ with no buffering issues. The interface is really easy to use, which makes managing everything a breeze. Plus, having a whole community of smart people available for guidance is a huge bonus.

I was sold from the start, which is why I quickly upgraded from a 1-month to a 3-month subscription, and I’m planning to switch to a 1-year plan soon. This service totally pays for itself, and I’m sure you won’t be disappointed. It’s been really impressive.

Best possible options for anyone looking for the do-it-all option along with the best customer service ive experienced in this space so far. Id rate it a 6 if I could but its limited to 5/5...

(responding to a discussion re the cost of ElfHosted vs mainstream streaming / self-hosting):

I didn't know that the goal of this project was to compete with large companies running/renting entire DCs. I was under the impression that the goal of this project was to manage the updating of almost selfhosted applications on a shared platform with other users. Basically, be my sysadmin for me.

That being said, paying for services is the 'easy button'. There is a real world cost incurred for the time saved. Time is money. Time is the most valuable currency that exists. Once time is spent, it's forever lost, one cannot retrieve it again (yet). In my mind, there are 3 options for use of time with respect to: mainstream, selfhosting, elfhosted.

  • mainstream - my time is valuable and I don't want curated content and I don't care what content that I have the ability to consume. I only like what's popular.

  • elfhosted - my time is valuable, I want my own curated content without being forced to browse past the same damn entry 500 times just to find out that I can't watch the movie I want because it's not available in my current location or was removed last week from mainstream providers.

  • selfhost - I care about costs and I have nothing but time to waste or I want to learn about the backend of the systems involved. I'll pay for my own VPS/homelab, electricity, manage the OS, manage app updates, figure out how to make the apps talk nice to each other, create my own beautiful frontend.

I know how much my time is worth, does that reddit poster know how much their time is worth? Without knowing what you are worth, you can't make effective capital expenditures with respect to the time it will take to recoup the capital.

I know I don't need elfhosted at all for my use case. I choose to stay with elfhosted because it's my 'easy button'. It's an efficient capital expense for the amount of time it saves me managing my own hardware, apps and saves me electricity costs. I'm also in a situation where I don't have upload bandwidth from my home to serve HD content to myself remotely. If I lived back in a city, I would still be here. My time is worth $$/hr.
