New Flattr extension in closed beta

First users to test the revolutionary zero-click payment solution

For many months now, we’ve been internally testing the new version of Flattr. The browser extension cleverly understands which content a user really likes, and on what content he / she spends a lot of time. These sites are automatically flattred by our shiny new Flattr extension and content creators / publishers receive a share of the user’s total monthly Flattr budget.

With the relaunch of Flattr, we’re taking the next step in completing our vision of putting the user in charge of a fair, profitable web. Flattr and eyeo, the maker of of Adblock Plus and Adblock Browser, teamed up a little while ago to work on improving Flattr. Just recently, the Flattr guys officially jumped on board the eyeo team. Even before joining, both teams felt passionately that users needed an easy tool to reward the content makers they love. Now that we’re working together, it’s time to double down on that vision.

Today we dare to open the circle for a few users to test the ins and outs of the closed beta so that the open beta, coming later this year, is ready for the general public to take on.

This version is fully functional, allowing the first beta testers to use the completely revamped interface, and of course to witness how the built-in algorithm automatically flattrs whatever they love: cat videos, real news, fake lashes tutorials, tech blogs, poetry sites and on and on … As always, users can see what they flattred and delete flattrs on The closed beta will allow users to flattr without money, as one of the goals of this version is to make sure that everything runs smoothly once users can actually put in real money to reward their favorite content creators online.

All of you who signed up for access to the initial beta release will get an invitation. We are starting with those who signed up first and will increase the number of users within the next few weeks. So if you signed up, check your inbox to find your invite code!

You’ll get access to the new extension if you already use Flattr.

Want to use the new Flattr but haven’t signed up yet to the list? You can still do so at!

Adblock Plus & Flattr join forces

Today is a very happy day for us and we want to share some great news with you: Two of the most out-of-the-box thinking organizations on the web have joined forces in order to build a sustainable Internet!

The new Flattr extension will allow users to directly and sustainably fund content they love – simply by browsing the web. “Together we will be able to create an Internet which is fair to all, sustainable and safe.” says Peter Sunde Kolmisoppi, co-founder of Flattr.

Since we partnered up last year to create the new Flattr, we noticed that we had similar values and goals for our projects. Subsequently, we decided it makes more sense to remove the barriers that come from working as two separate teams and integrate into one united team. Our goal of making the Internet safe and fair for all is much better served when we’re totally aligned. Thus today, eyeo, the company behind Adblock Plus, has acquired 100% of Flattr AB, the company behind Flattr.

Flattr has been creating the world’s first micropayment system that works for virtually all content online. Our model is based on how the distributed Internet works, with lots of information from an endless amount of sources. We no longer read just one newspaper or listen to just one album, we read all and listen to all. While the media industry is struggling to overhaul their analog business models to survive in a digital world, we’ve modeled a solution that takes the status quo into context. We’ve made a new, fair for all, way to pay for content.

Primarily used as an ad blocker, Adblock Plus is also viewed as the open web’s largest content curation platform. It allows users to block content they aren’t interested in, but still helps content creators earn revenue. With the Adblock Plus user base of more than 100 million and the technology of Flattr, we will create a new Flattr. It’s a game changer for how money is distributed to creators directly from their fans, readers and consumers. All in a transparent and fair way.

“At eyeo we’ve always looked for ways to make the web more fair and less annoying. We started with Adblock Plus, which helped pioneer the idea of constructive ad blocking: letting in better, more respectable ads that ad blocking users accept. Flattr makes micropayments automatic and effortless, thus it will be the most user-friendly payment solution on the internet. Together, constructive ad blocking and Flattr complete eyeo’s vision of putting users in control of an internet that is fair and still profitable,” says Till Faida, founder of eyeo, the company behind Adblock Plus.

Flattr will be able to provide content creators payment for their work and also act as a quality shield. Creators will earn more money for producing higher quality work that keeps the audience engaged, while clickbait will earn much less. Sometimes you need to totally rethink how a system works – and that’s exactly what we’ve done. We’ve thrown out the old way of thinking and replaced it with a new way of thinking in order to be helpful to all parts of the chain.

In Sweden (where Flattr is based), there’s a saying, “många bäckar små, blir en stor å,” which roughly translates to “many small streams form a big river.” Flattr is a river of hundreds of millions of revenue streams.

The core team of the original Flattr company will continue its operations with all staff members from Malmö, Sweden. Peter Sunde acts as the visionary advisor he is known as and his co-founder Linus Olsson will continue to head the operation and implementation.

To get early access to the new zero-click beta Flattr join the waiting list.

It’s always darkest before spring. fp-progressYes we live in Sweden and the winter is damn dark. But in this case, spring is the release of the beta version, and the sun is already peeking over the horizon.

So you can imagine, that we are pretty busy these days. But now it’s time to give you a quick update!

Current status of Flattr Plus
The add-on itself is basically ready for beta. What we are currently fine-tuning is the brain of the browser add-on, the algorithm that makes sure your money goes to the sites you really engage with and want to be funded. We are testing multiple versions of that algorithm internally to identify the one that will make it to the beta release.

Meanwhile, our designers and UX people are putting the finishing touches on the add-on as well as on the “new” sign-up experience for creating the Flattr account. As Flattr Plus relies on as its backbone, here is where users and publishers will sign up to use Flattr Plus.

To make sure we develop something that you want to use, we are continuously talking to potential users and publishers. Right now, we are conducting a couple of interviews to better understand users’ needs and expectations of Flattr Plus and their attitudes towards rewarding web content that they enjoy.

What’s next
Before the end of the year, we will start a closed beta version to get in-depth feedback for the functionality and the overall experience with Flattr Plus. We are super excited to finally get to that milestone, and will keep you posted.

And for the ones who prefer text over pictures, we have something special on the way: as we put a lot of thought into the idea of voluntarily funding content, and especially the development of the algorithm, we decided to write all of that down in a detailed whitepaper, so anyone interested can understand our approach. And of course challenge or even modify it. As we want to include the beta version of the algorithm and the results from the closed beta, the whitepaper about Flattr Plus is scheduled to be published early next year.

In the meantime, stay warm in the winter darkness!

Flattr Plus update #2

Howdy! The dog days of summer are passing over us hotly, turning most people into lazy sun seekers and vacationing hordes. But not us. Nope, we’re keeping our shoulder to the wheel, diligently hammering away at this revolution called Flattr Plus.

The Swedish summer is the best day of the year.

The Swedish summer is the best day of the year.

Ugh? Nope, actually, zero “ughs” are being uttered round here. We’re having fun reinventing the way the internet gets paid. Our summer labors come amid a bit of crisis in publishing, as more and more users reject ads that are too intrusive. So it’s no surprise that according to recent research, most publishers are looking beyond ads for monetization. In fact, only a scant 11 percent rely exclusively on ads – a full 78 percent rely on the “ads-plus-other-stuff” model.

That is to say, Flattr Plus’s timing couldn’t be better, because while some of that “other stuff” is just fine, the web needs an easy, automatic solution that is not exclusive to particular sites. Here’s a rundown of how our project to do just that is progressing:


The data science we’re tinkering with here is always the most interesting category. Sorry, other colleagues, but it’s theoretical and expanding and evolving from week to week.

Data is fun!

Data is fun!

This time is no disappointment, because recently we’ve been working on creating a whitelist of sites that will be enabled for automatic flattring as standard. This means sites that Flattr Plus are allowed to flattr by default (users can add sites beyond this list to their personal whitelist).

But what qualifies a site for flattring? And how are we specifically deciding what to include on the default whitelist?

Well, we broke it down to a single, core question that must be answered affirmatively in order for a site to qualify: do you think the majority of internet users would like to flattr this page? Clearly, though, that means we have to figure out what content most people would want to flattr. This has been a big challenge, but here are the (very) simplified criteria we’ve been using to fill that list:

  • The website provides content for free, e.g., journalistic content, news, blog articles, information, videos, music, podcasts, etc.
  • The website monetizes via ads, donations, a (soft or hard) paywall or does not have a monetization model in place.
  • The website does not mainly serve as a way to promote or use a product or service that needs to be paid for, e.g. shops, marketplaces, product websites, restaurants, banks, insurance companies, etc.
  • The website is not provided and/or maintained by the government.

But there are other sites that we felt should not be automatically flattrable? So even though our approach is pretty much content agnostic, websites that serve pornographic, racist or illegal content do not qualify for the whitelist. (If they qualify for Flattr at all.)

Where to begin to fill up such a list is a wholly separate challenge. We started by looking at the top 100,000 Alexa domains, but because we don’t have the person power to go through 100,000 sites and compare them against the criteria above, we’ve been hiring this out by posting short-term, crowd-sourced jobs.

We’ll let you know when the list is full!

Flattr Plus update

Since we announced Flattr Plus in early May we’ve been working hard to perfect what we believe is the web’s missing (monetization) link. It’s been encouraging, and exciting, developing an easy, automatic solution to fund content. We’re still on track with the closed beta, which will be ready in the early fall (sign up here), and the open beta, too, which is planned to launch late fall or early winter.

For now, we wanted to inform you about the developments on Flattr Plus that have happened since May. Specifically, we wanted to show you how the design is progressing, give you a peek into the data intelligence and development going into the add-on and tell you about the new API on

So we’ve done a lot of conceptualization and engineering to make Flattr Plus run like a well-oiled machine on the inside. But what about on the outside? How does it feel from your perspective as a user? Sure, Flattr Plus will allow you to easily and automatically fund your favorite content, but is it free-flowing and intuitive?

The short answer is yes. This is an interface we created for testing and collecting feedback. Bear in mind, this is just a testing screen we’re using to sharpen the algorithm.


The interface for collecting user feedback for the beta algorithms.

One of the biggest challenges the Flattr Plus project faces is determining what signifies a flattr? What browsing activity, in other words, should trigger a monetary transfer to a particular site? And how do you keep that as private as possible?

It’s sort of the crux of everything: making flattrs automatic is what makes Flattr Plus unique: no one’s ever made a payment system quite like Flattr Plus – even Flattr. One of the first things we did to shine light into this unknown territory was to just gather browsing behavior from our friends, colleagues and family, who volunteered to share all their browsing data. The idea was that by taking the maximum amount of data possible, you find the minimum amount required for the add-on to work. The process is a bit like whittling a stick: you start with a large, unwieldy piece, then carve it down to something small and intricate.

After analyzing all their browsing habits, we developed several ideas for algorithms that would trigger a flattr. Next we implemented a dashboard to show the output various algorithms produced.


Another test screen, the Add-on itself.

And of course we did some good, old-fashioned interviews of our friends/guinea pigs. However, before we could extend the test to real beta testers (you), we needed as privacy-friendly a way as possible to get useful data. This was made possible by the stick-whittling process I refer to above, but beta testers will have to volunteer some information if they want to test (of course we absolutely tell them this in a big, fat disclaimer). The final version available to the general public will be 100 percent privacy-friendly. This is a requirement for us, not a mere priority.

For now though … still whittling that stick, not to mention polishing up the code and freeing it of issues. Finally, deciding what triggers a flattr is relevant to how the add-on will function – but what happens when the add-on sends data to, so that it can disburse money to worthy content creators?

Well, the rollout of Flattr Plus demands a fairly significant number of changes to the existing Flattr system. The most substantial part of this is a rebuilt API and a new approach to how flattrs are handled. Chief among those new approaches is getting rid of “things.” Previously, as existing Flattr users knows, Flattr worked by allowing a number of elements – “things” – to serve as identifiers for what was able to be flattred. For Flattr Plus the sole identifier for what is flattrable will be the URL, i.e., the add-on will send the URL to the Flattr API using a secure connection, and the Flattr API will determine the owner of the URL without knowing the behavior that led to the flattr; so obviously, we had to do away with “things” as identifiers as mentioned in our last post.

We are now also starting to create the all-important onboarding for new users, how Flattr Plus will be integrated into Getting the add-on in the browser, creating an account, the payments flow and the dashboard all have to work perfectly together with Flattr Plus.

Finally, we’ve been speaking to publishers worldwide about opening their sites to receive funds from Flattr Plus users. Thus far those conversations have been very fruitful, and we’re pleased to report that publishers have shown a great deal of enthusiasm to employ Flattr Plus when it rolls out.

Flattr developer update #8 – Some API updates

In preparations for our upcoming launch of FlattrPlus, we are refactoring our internal system structure which in some cases means that we need to make rather large changes to how the system operates. In this particular case ‘things’ as a concept must go.

We will no User-Interface-Exit-iconlonger allow the creation of things. In fact we will no longer store most of the data that is now presented as a thing. For most users, this mean nothing. The new system has already dropped all lists of things, the thing pages has been stripped down and you can’t edit the information for a thing. All this because we have understood that things would be dropped as a concept in the future, that is now.

But, if you are a developer building an application that either relies on the creating or fetching things endpoints in the current API you need to know what these endpoints will soon be deprecated. We have checked and already contacted all developers of registered apps that we see are are using these endpoints. But if you are building something that yet has not seen the light of day we can’t know that.

Since fetching or creating things are not necessary in order to Flattr a URL we would want to know more about how you are using the API and how we can help you transition to another solution. Please contact us and we will help you out.

Flattr Plus in the media

Almost a week after the announcement of Flattr Plus it’s time to sum things up and answer some of the questions we got. But lets begin with the re:publica presentation.

Watch the first presentation of Flattr Plus from re:publica

Re:publica is one of the biggest conferences on digital and society, happening each year in Berlin. We are proud to present Flattr Plus to the public there for the very first time. The video shows Peter Sunde, co-founder of Flattr and Laura Sophie Dornheim of Adblock Plus on stage at re:publica explaining why the open web needs a solution like Flattr Plus and how it is going to work.


What the press wrote about Flattr Plus

Wall Street Journal, TechCrunch, Wired, Ars Technica, Fast Company, Engadget, PC World, Business InsiderYahoo News, Mashable, The Verge, Venture BeatGuardian, Fortune,, Der Spiegel, Golem, amongst others.

There have been some questions that have come up often, here are the answers.

Q: What exactly is Flattr Plus?
A: It’s the coming browser add-on that flattrs URLs automatically based on your attention and engagement with the web page. It’s built as a cooperation between AdBlock Plus and Flattr.

Q: Do I need to use AdBlock Plus to use Flattr Plus?
A: No, Flattr Plus will be available as a stand alone add-on.

Q: Will Flattr Plus be integrated into AdBlock Plus in the future?
A: That is the plan.

Q: How will the automatic flattring work?
A: We will measure your attention to the content locally in your browser, when a certain amount of attention has been reached the page will be flattred. How much and exactly how it will work is something we need real beta user feedback on.

Q: How do you protect my privacy?
A: Only URLs that get enough attention will be Flattred and only sites that are on our default whitelist of domains. You can always block any domain permanently and we do not get browser history. All Flattrs done are only visible to you and the receiver, but they don’t know who made it.

Q: Can I use my old Flattr account and/or money?
A: Yes, Flattr Plus uses Flattr to do all flattrs and transactions. (You could think of Flattr Plus as a Flattr app.)

Q: I want to try it!
A: Then sign up to the beta list at to get access as early as possible.

Q: I’m a publisher, how do I get our content to work with Flattr Plus?
A: You sign up to the publishers list at and we will get back to you with more info when it’s time.

Q: We are a publisher, do we need to have Acceptable Ads to use Flattr Plus?
A: No, not at all.

Watch our video explaining why we do this

As always, we love feedback!

Announcing Flattr Plus

Today  we are delighted to finally announce something we have been working on for a very long time. In order to accelerate the implementation of Flattr everywhere, we’ve partnered with Adblock Plus. flattr+abpThe two systems share the same ideals, of making the web a cleaner place while making it financially sustainable for those who create the things we engage with.

We call it Flattr Plus and today we’re announcing this plan for the world. It’s will be an add-on for your browser which will automate your flattrs for you, as well as removing the need of implementation of the system for the publishers. Instead of a one-click to flattr someone, the systems goal is to fully automate the flattrs – zero click payments if you like. All based on your engagement with the content.

We’re proud and excited about this opportunity and think this will really make a huge difference in how the web will look. Micropayments on an automatic scale is the missing link in the internet we all love and need and we’re super happy to be part of this huge step forward in supporting the open web.
