Ask HN: How are web browsers monetarily supported?

[uticus]

I've seen (and had) many conversations about how web browsers are ubiquitous, and I'm familiar with the engineering aspects of those conversations. But I was recently struck by how I don't understand the monetary aspect. Any good material / data on how the most widely-used web browsers is supported monetarily?

There is information available via Google search, but I'm curious what the HN crowd thinks. Besides, maybe it's just me at the end of 2025 but I'm starting to get paranoid about info on the web being accurate about the monetary foundations of the web... if that makes sense.

Advertising, search partnerships, premium subscriptions afaik.

These things can be found public:

- Opera https://investor.opera.com/news-releases/news-release-detail...

- Mozilla (largely funded by google) https://en.wikipedia.org/wiki/Mozilla_Corporation

- Brave https://brave.com/blog/100m-mau/ (ads, search api, premium subscription, and their crypto thing)

- Browser company: not sure, I think they have a subscription, but I assume they still mostly run on VC money.

Chrome, Safari, and Edge are funded by their parent companies. I believe Google does also pay Apple $20B to be the default search engine on Safari and ios.

So you could make an argument that Google pays for browsers. A lot of browsers run on Chromium, owned and funded by Google (although technically open source). Except Apple and Mozilla who get search money from Google.

Of course, but how do the parent companies fund them?

If I were a company, I'd only fund something if it provided capital (or the reasonable assumption of capital in an agreeable timeframe). But nobody is paying for Chrome (Google Chrome), Safari, or Edge.

Someone may say "but everyone uses a browser. If Google stopped releasing Chrome it would upset a lot of people." Of course, but Chrome is a huge effort, very complex, lots of money. Google isn't pouring money into it because it makes lots of people happy, nor are they doing it because they have a gun pointed at them (although I bet legislative guns would appear quickly if Google did unexpectedly pull Chrome from the virtual shelves). So I'm left with the only alternative: money being moved from something revenue generating (probably advertising as you've mentioned or selling datasets etc) to the Chrome effort to keep it going.

My question is about the specifics. These are publicly-traded companies, but a lot of the decisions are opaque. Has anyone here on HN come across good data or analysis of specifically how money is moved around to support the huge efforts of maintaining popular web browsers?
