I built a browser-based P2P file transfer tool using WebRTC

You have some web page material in English, and some material in either Spanish or Portuguese. You might want to check everything twice before posting on HN.

Not the poster but I had to go check the website to see this. I believe it is in Spanish. It makes me pretty happy to realize that even though I have had little or no conversations with Spanish speakers for about 30 years I was able to understand the untranslated text. There is so much that clicked once I had the context through the words that I recognized. The rest of it began to make sense.

Thanks for that mental exercise.

that's genuinely nice to hear. Thanks for taking the time to explore it despite the language mismatch, a consistent English version is coming

What happens when TURN is inevitably needed? Many people are behind something like CG or symmetrical NAT with no direct way to talk to each other.

There are no reliable, fast AND free TURN servers (IMO), and even semi-private relays can quickly become overwhelmed or too costly to operate.

Bandwidth costs money not to mention if it was truly free it would probably be an abuse vector. Cloudflare offer 1000Gb free per month - https://www.cloudflare.com/products/turn-sfu/ and pricing beyond that isn't bad either.

thats one of the main operational challenges. AirDows attempts a direct connection first and only uses TURN when NAT conditions require it. I'm already measuring relay usage and evaluating sustainable TURN providers and limits while keeping the beta free...

Hi, I built a plugin-based P2P socket system from scratch that supports TCP punch, UDP punch, random probe, TURN, and other such systems. It includes a full stack from networking, signalling, and naming, all based on open infrastructure. It's open source and licensed under MIT:

Looks great. How long until it does P2P via Bluetooth?

Like Bump did before it was shut down by Google.

I guess this sort of tool provides a good learning experience for developers or implementing one scratches some other itch, because there are so many one here:

Does anyone know what the actual success rates for webRTC are for like different NAT combinations / nodes in the wild? I'd be curious, I have read a little into it myself but didn't get the feeling it was very flexible compared to something like Tailscale.

https://gist.github.com/SMUsamaShah/fd6e275e44009b72f64d0570... I keep a handy list. Does this stream file directly to disc or keep it in browser cache or memory? In this list I think only web wormhole does that which means it should be able to transfer huge files without any problem. Most tools crash if files are in GBs.
