Major Open Source Projects: How much money do they actually make?

Comparing the revenue of some of the biggest names in Free & Open Source Software.

May 10, 2023

Here's a seemingly simple question: Which Open Source projects and foundations bring in the most money? And, as a follow on to that... which bring in the least?

GNOME? KDE? Mozilla? Apache? The Free Software Foundation?

There are a lot of big names in the open source world... but how much money do the most recognizable names in Free and Open Source Software actually earn in yearly revenue?

I wanted to know. So I collected revenue details for 17 major open source foundations -- by digging through IRS filings, Annual Reports, and every other source of information I could get my hands on.

Then I stuck them in a spreadsheet and made some fancy-shmancy charts.

Some of the results were expected and obvious... others I found truly surprising. Honestly, some of the results are a gosh darned travesty.

It's charting time!

Let's start by putting all of the open source foundations into a single chart, and sort them... in order.

Note: Some of these organizations had not yet published their fiscal numbers for 2022... thus I used 2021 numbers across the board.

Wow.

The immense revenues of Mozilla ($600 Million), The Linux Foundation ($177 Million), and Wikimedia Foundation ($162 Million) really skews the chart.

But that was to be expected. We all knew that those three organizations brought in mega-bucks.

So let's get rid of those three completely and re-do the chart.

There we go. That's actually somewhat readable now.

But... holy smokes. I had no idea the Eclipse Foundation was that big. Bigger than some of the biggest names in open source.

Let's go ahead and get rid of the Eclipse Foundation as well. Really zero in on the projects that are big, big names in the world of Linux, BSD, and open source.

Note: I broke out Thunderbird (the email client) from Mozilla, even though it is technically part of Mozilla. The Thunderbird project reports their revenue indipendently, so I thought it would be interesting to compary the donation revenue from a single application with some of the other foundations.

I find this chart absolutely wild.

Here are just a handful of observations based on the data above:

KDE and GNOME are among the major open source foundations with the smallest revenue. Each barely earning enough to pay for a few full time employees.
The Software Freedom Conservancy (aka "SFC") brings in more revenue than The Free Software Foundation, Apache, and FreeBSD combined. I knew that the SFC had been active in multiple legal matters, and aided several projects... but I had no idea that it was, in all reality, the largest foundation focused on supporting Free Software.
On that same topic... that also means that the Free Software Foundation is not the largest foundation focused on supporting and advocating for Free Software. Huh! Who knew?
The Open Source Initiative is bringing in close to half a million per year? One has to ask... why? What do they do that's worth almost as much as GNOME and KDE combined?
The Rust Foundation sure does bring in a lot of money. Considering their recent objection to people using the word "Rust"... this raises a lot of questions about what their plans are and what they are using those dollars for.
Thunderbird brings in more revenue than Blender? Wild! I was not expecting that.
On that note... I see significant new features and updates happening with Blender regularly. But not so much with Thunderbird. Clearly Blender is better at using those funds for development than Thunderbird.
- As a follow-on to that thought... Thunderbird Revenue jumped to over $6 million last year, in 2022 (the data for this chart is from 2021). Do we really see $6 Million in improvements to Thunderbird every year?
Not to harp on Thunderbird... but more money goes to the Thunderbird Email Client than... GNOME, KDE, OpenBSD, and FreeBSD... combined. And that's before that 2022 revenue jump.
FreeBSD brings in more than twice what OpenBSD does.

Overall, one thing that strikes me is how astoundingly little some pretty critical projects and foundations bring in. Considering the prevalence of the GNOME desktop -- and usage by Red Hat, Canonical, SUSE, and so many others -- I would think it would be better funded than that.

While this data does not represent every project or foundation in the open source world... it is a solid cross sample. And I found the results, at least in some cases, a bit... weird.

The futility of Ad-Blockers

Ads are filling the entirety of the Web -- websites, podcasts, YouTube videos, etc. -- at an increasing rate. Prices for those ad placements are plummeting. Consumers are desperate to use ad-blockers to make the web palatable. Google (and others) are desperate to break and block ad-blockers. All of which results in... more ads and lower pay for creators.

It's a fascinatingly annoying cycle. And there's only one viable way out of it.

openSUSE says "No Lunduke allowed!"

Those in power with openSUSE make it clear they will not allow me anywhere near anything related to the openSUSE project. Ever. For any reason.

Well, that settles that, then! Guess I won't be contributing to openSUSE! 🤣

Assisted by Antigravity 2.0 and Gemini 3.5 Flash.

Codex and Claude Code are my bread and butter tools, but I keep my $25/mo Gemini subscription and keep tabs on its progress.

They came out with an unabashedly clone of OpenAI's Codex. In their global demo showing off Antigravity, a screen shot clearly shows a folder named Codex. That's actually a good thing. Steal from the best.

I've always liked Gemini models for conversation, but they have not been top tier for coding and certainly not agentic coding. They've made great progress. As far as I'm concerned - one of my favorite YouTubers thinks they still suck. Try for yourself.

I used Antigravity and the new model as one of the adversarial reviewers for the Sci Fi serial I created. It was more heavy on praise by default. Still, quite competent and very speedy. You can fix the glazing by prompting more specifically.

Then I had it create the web page for the book - which you can see in the link above. It was ...

Silver Lining - Linux Part 1 of ?

Be the solution…is that not one of the driving forces behind open source software? Create what you want, build a community of enthusiasts and share. I have become increasingly alarmed at my online friends here and the doom mind-virus that I see. Not from a “doom is wrong” perspective as there are plenty of worrisome and frustrating situations out there. Rather, I see the loss of joy and hope. Doom has ascended to our collective and individual detriment. So, I am embarking on some joy posts. And this Mac daily driving, iPhone using, cloud loving AI practitioner thinks there is JOY in Linux. Oh yes, plenty of current joy. Take Microsoft Azure Linux, pure joy.

Consider that it wasn’t that long ago that Microsoft, Sun and Novell (does anyone even remember?) tried to literally kill Linux. They tried to strangle Linux in the crib. Sun and Novell are no more, and Microsoft’s present and future runs on Linux.

The Year of Linux on the Desktop never happened,...

Lifetime "Solaris" Wall almost full!

Just a quick heads up that the 7th “Lunduke Journal Lifetime Subscriber Wall”, aka “The Solaris Wall”, is almost full!

The Solaris Wall has enough space for maybe 6 or 7 more names (depending on name length)… before we lock it down and move on to Wall Number 8 (which will be another retro computing platform).

If you’re already a Lifetime Subscriber and want your name added to the Solaris Wall, just drop me a line (contact info on Lunduke.com).
For those of you who are not a Lifetime Subscriber yet, you can grab one right now at a hefty discount.

Hard to say how long until the Solaris Wall is full… but no more than a few days. These things fill up fast.

First come, first served.

Huge thank you to every subscriber. The Lunduke Journal wouldn’t be possible without you. You rule.

Last call for the "Amiga" Lifetime Subscriber Wall. It's almost full!

Holy smokes, that was fast.

The 6th Lunduke Journal Lifetime Subscriber Wall (aka the “Amiga OS 3.1” Wall) was introduced… what… a week ago?

I kid you not, the darn thing is already almost full! I was wildly unprepared for how popular this would be!

There’s enough space left for maybe 5 or 6 more names. Tops. Then I’ve gotta declare “Wall 6 (Amiga) is Full” and start Wall Number 7!

Here’s what all of the Lifetime Subscriber Walls look like (each shown at the end of every Lunduke Journal video):

If you want to get onto the Lifetime Subscriber Wall (and have any chance of making it onto the Amiga Wall before it’s full) here’s what you need to do (and do it quickly):

Grab a Lifetime Subscription to The Lunduke Journal (if you don’t already have one).
1. A Lifetime Sub includes all the standard perks (plus a few) and can be picked up via Locals, Substack, or Bitcoin (whichever you prefer).
Email “bryan at lunduke.com” and let me know how you would like your name displayed (“Joe A.”, “Joseph Arnold”, “JoeyPants”, “SirJJMcManly”, etc.)

It’s first come, first served.

If you’ve already emailed me about being added to the wall, your spot is secured.

For the rest of you: Chop chop. At the current rate, I would be very surprised if the “Amiga Wall” wasn’t full by some time this weekend.

“Lifetime Wall 7” will be unveiled after the final name is added to the Amiga Wall. And, yes, it will be a different (awesome) retro computing platform.

As always, a huge thank you to every subscriber to The Lunduke Journal. Absolutely none of this would be possible without your support.

Amiga Lifetime Wall & March Lunduke Journal Stats!

Hello all of you amazing Lunduke Journal subscribers!

With March now behind us, I wanted to give you crazy kids a quick “behind the scenes” look at the stats for The Lunduke Journal. Because Inside Baseball stuff is fun.

The Amiga Wall!

But before we dive into charts and numbers… behold! The brand new 6th Lifetime Subscriber Wall of ~~Shame~~ Awesomeness! The AmigaOS 3.1 Wall!

Every Lifetime Subscriber Wall (which I show at the end of each video) is a real screenshot from a different computing platform. Mostly retro. All awesome.

If you’d like to see your name listed on the new AmigaOS 3.1 wall, grab a Lifetime Subscription (if you don’t already have one) and toss me an email. I update the walls about once each week with new names.

The last few Lifetime Walls filled up incredibly quickly. So if the Amiga Wall interests you, I wouldn’t wait too long. Hint, hint.

March 2026 Stats

The big news: Total “views” were way, way up in March.

A fair bit beyond what was anticipated. A hair over 19 million during the month.

That’s in total, across all platforms. As usual, the audio podcast and X lead the way in terms of total views/listens for shows (by quite a lot).

Interestingly, we saw significant “views” growth on even the smallest platforms in March (Facebook and TikTok).

Free subscribers also took a major jump in March, with the largest one month gains ever (I’m pretty sure, certainly the largest this year or last). Up 7,623 over the month before.

Again, new subscribers grew across the board. The biggest gains were seen on X, but all platforms saw a significant bump.

Hard to complain about that!

The top 3 shows for March were all focused on the Age Verification laws:

While those were the top 3… it’s worth noting that the top 10 (and, really, the top 15 or so) shows for the month were all incredibly close in terms of viewership numbers.

As always, a huge thank you to all of The Lunduke Journal subscribers. You make all of this possible.
