Show HN: Mtproto.zig – High-performance Telegram proxy with DPI evasion

Hey everyone. I built an MTProto proxy for Telegram aimed at bypassing active DPI censorship like the Russian TSPU. I chose Zig because it's perfect for writing fast network daemons and makes it incredibly easy to port low-level C bypass techniques like TCP desync and packet fragmentation. Would love to get some feedback or contributors!

that looks very interesting, indeed. do you think it could work in places like iran too during current internet shutdown? some people use things like dnstt to get connected but it's extremely slow and unstable.

thanks for your work

If they are implementing a complete blackout - dropping international routing and switching to a default-deny intranet - this proxy won't help, sadly

It could if connectivity to Telegram were brought in through e.g. Starlink. Users would connect to the proxy (an Iranian address) which forwards the requests to the outside world.

Interesting project! As someone building a voice-to-text keyboard (Echo), I appreciate the craftsmanship here. The attention to detail in developer tools makes a big difference for the end user experience.

Have you built it, or have you had AI build it?

Yeah it does. If you're happy routing your personal data through software that lacks an author who fully understands what the software does, good for you. Suggesting that this doesn't matter in general is.. not an opinion I'd share publicly.

Very obvious with the GEMINI.md.

I wish there was a rule to ban AI submissions. Not because I think there's 0 value, but because there's just such a high volume and low signal to noise ratio
