Was it really $25k, or was it done though subscriptions with a reported cost of $25k?
I'm on the openai $100 sub and frequently my codexbar will show $250 usage in a day. I think it probably doesn't have access to the cached token share too, which probably inflates that a lot.
I'm so glad this exists, I've been considering doing something like this for a few months.
I recently got a TV based on VIDAA os, a locked-down linux-based OS where everything is rendered from Web pages. It has a built-in browser that doesn't support ad-blocking (I suspect VIDAA is profiting from showing ads on the TV), and you can't install new apps unless they're Web pages.
This would hopefully allow one to run Firefox within the existing browser, then install uBlock Origin within Firefox... I know what this weekend's project is going to be...
We also plan on adding extension support to https://github.com/HeyPuter/browser.js soon, which should hopefully cover use cases like that as well without the full overhead
Firefox should really bundle ublock origin as-is. I install it afterwards anyway but I don't understand Mozilla here. They seem to want to stay behind Google.
In 2024, "search royalties" brought in approximately $585 million for Mozilla, largely from Google. It's not hard to see why they tread very lightly around ad blocking. It's actually impressive that ublock remains easy and painless to install as an extension.
Oh and for anyone asking, you can run firefox-wasm inside firefox-wasm inside firefox! I only got this to load once though since it gets pretty unstable at that level.
The websites that don't want you to block ads will serve you an obfuscated "inner browser" that will render their site. All your ad blockers, etc, are rendered moot.
Once accessibility is solved this is absolutely going to be a thing on major websites.
In mean... It kinda feels like this is legitimately true? An attacker trying to do anything on a user's machine through this would have to find a Firefox vulnerability and a vulnerability in the wasm runtime, which is such a high bar that I would actually feel remarkably safe running this thing. The only question is how performance works and whether there are any pain points using as a daily driver, but those feel likely to be a pretty minor point. Oh, and the usual caveat that an attacker can still compromise things inside the sandbox which does leave a certain amount of exposure (but if you run different things in different instances they're isolated).
This is true but also this is probably also only half true. Sandboxing is not a fully solved issue since this 100% degrades firefox sandboxing since fission cant run and its running in singleprocess mode. Just wanted to be honest about this
What's your GPU driver? There's a good chance this is a bug with the GPU passthrough. You can fall back to software rendering in the advanced options while it's starting if you want to try
25k tokens to port Firefox to WASM. by 2027 we'll be spending 25k tokens to port WASM back to native because someone will benchmark it and find the WASM version is 3% faster.
All the network traffic from that browser is routed through a server. My IP inside that browser was in India and on CloudFlare network. I don’t particularly trust Puter. Why not route traffic through my actual browser?
Because the web browser can't make arbitrary network connections. Even if it was implemented intercepting at the HTTP layer (which would probably be much more difficult than just intercepting the low level socket operations) you wouldn't be able to properly manage CORS headers, cookies and various other things.
The TCP proxy exit node we're using is running on Cloudflare, you can check that your traffic is still TLS encrypted by OpenSSL (also compiled to webassembly). The browser does not have a native API to send raw TCP so the proxying is done by the http://github.com/MercuryWorkshop/wisp-protocol protocol. You can check your packets in dev tools, look for a socket connection with "puter.cafe" as the host for our TCP proxy. This application is meant to be a demo for it actually (why it says at the bottom that its powered by puter networking). That is the only server side component of this.
I was reading your landing page at https://developer.puter.com/networking/ and was very confused by how you were achieving the "with no server or proxy" part, until much further down the page:
> "the connection is tunneled over a single WebSocket to a Puter relay"
Come on, it's both a server and a proxy, and it doesn't stop being those things just because you're calling it a relay.
I wrote that and I think you're right. We were trying to convey that you don't need to set up anything, but the wording could definitely be better. I'll change it.
apologies yes there is a wording error here, the correct wording is no CORS proxy, the reason why this is important is because cors proxies are inherently insecure (this is different because the TLS is done in your browser with a webassembly library).
no servers is referring to you not needing to host servers in the same as the term "serverless". Such is the ways of modern tech terms I fear
Because you can't. Not even an Extension is able to. Browsers don't want you to bypass their content enforcement. I wish we had at least one hacker friendly browser.
Extensions can't, correct but I wanted to bring up a special case regarding this
Isolated web apps a chrome feature for developing apps that run in chromium based on HTML (but tbh only really used in Chromebooks) do support raw TCP sockets so if this was ported to an IWA you could have Firefox on a Chromebook without an external server needed.
Puter's networking is open-source and e2e encrypted. Also, a regular browser doesn't give access to raw TCP sockets used for this, so it wouldn't be possible to route through your browser.
So it's just the three accounts you have now? (Show by @coolelectronics now and 7 months ago [1], show from you/@ent101 2d ago [0], 2025[2,3,4], 2024[5,6,7,8,9,A,B,C,D], 2023[E], @george0812 2022[F])
The 21 on github, do you mean? And only nine above 3 commits ever? Yes you post regularly, too much even, and in the face of the guideline Please don't use HN primarily for promotion
nobody (hyperbole, corrected: few) follows that promotion rule. and where are you getting 21 from? the github repo https://github.com/HeyPuter/puter says 391 contributors, subtract maybe a few for bots
also, talk about posting too much? look at your own submissions page
What makes it require that WASM extension you need the flag for in Firefox? Was there really no way to work around it or polyfill it for it to work? It is performance critical?
It is required in order to yield the event loop and force an implicit sync on OffscreenCanvas. There is technically a slower workaround for this but JSPI is coming soon anyway to firefox 153 and safari 27.
I would be careful with this demo. When you go to whatismyip.com, it's showing: 104.28.233.73. Someone could use this to cloak their IP address and do some damage.
I think they had to solve the TCP connection, as normally you can't easily implement TCP sockets in WASM. So I suppose they just need to tunnel all the connection through some websocket.
edit: I misunderstood, that's $25k not 25k tokens :/ time to log off.
this is so rad! 25k tokens is a lot less than i thought this'd take -- what were the difficult bits in the porting process? also, was firefox preferred because parts of it are already in rust?
$25k of tokens, closer to 30 billion I believe. It only took a few days to actually get the engine up, the hard parts where most of the effort was spent was squeezing out performance and increasing stability, as well as attempting the JIT.
Firefox was chosen because its single-process support was in a better place than chromium/blink. WebKit is also possible, it was done by a friend of mine earlier https://github.com/theogbob/WebkitWasm
ah, i misunderstood. that seemed way too low in terms of actual tokens lol. i'll log off now. interesting details and didn't know about WebkitWasm. hope to read more soon.
Yeah I seem to see that it does crash on Firefox mobile, (well first frame loads) and on chrome mobile it doesn't seem to load at all (complaining about running out of memory in a small pop-up)
Does firefox mobile (Android, since firefox mobile iOS is a WebKit wrapper) support about:config settings? if so you can enable wasm_js_promise_integration in about:config and have it working likely. I will test this on my Pixel 10 pro
hi reporting back, yes stock firefox mobile wont work but the BETA version will because it just added the WASM feature needed (firefox 153 adds it but regular mobile firefox lacks about:config support it seems)
and by "will work" I mean will render the first frame and then freeze
> This was just a fun experiment to push the boundaries of WebAssembly
I'm a huge fan of the project, but I have to ask. If spending $25k is a "fun experiment", where exactly is your threshold for serious work?
I'm on the openai $100 sub and frequently my codexbar will show $250 usage in a day. I think it probably doesn't have access to the cached token share too, which probably inflates that a lot.

- copy paste
- scrolling with touch
- ai side panel
What works on mobile :
- Extensions !
This is so sick great work; did you try webgpu?

did you enable the about:config option? it may be required

I would love to see the details for this. SpiderMonkey had an attempted wasm32 JIT backend, but it was never finished.
edit: Apparently it also has some sort of WebAssembly interpreter backend too, which SpiderMonkey doesn't have.
Every year I need to rewatch this talk
Then I opened up https://developer.puter.com/labs/firefox-wasm/ in Firefox-in-WebAssembly-in-Chrome
... and sadly it didn't load. I got this in the startup log:
Pixel 10 pro user here
and by "will work" I mean will render the first frame and then freeze
YMMV
