DPIMech

Android DPI bypass app with some extra things.

Open the sites and apps your internet provider blocks with DPI (Discord, YouTube, Roblox…) on your phone, without root and without a remote server.

Features Setup wizard: pick the sites, DPIMech tests your connection and turns on what works. Whole phone or chosen apps: the sites commonly blocked in your country for every app, or only the apps you pick (e.g. Discord). Other connections are left untouched. Strategy Lab: tests strategies against real sites, with confirmation rounds, and shows which one works on your provider. Presets for known providers are tried first. Automatic strategy per network: on a new Wi-Fi or mobile operator it finds what works and remembers it. Encrypted DNS (DoH) for the bypassed apps, and an optional QUIC block so browsers and YouTube use TCP, where the bypass works. Live status: traffic chart, average ping of your sites and DNS counts on the home screen and in the notification. Widgets (one per profile if you like), launcher shortcuts that turn a profile on and open its app, Quick Settings tile. Quick check of one site (directly and through the bypass), profile backup to a file, start on boot and Android's always-on VPN. Strategies updated without a new release, plus a community list; DNS blocking check; watchdog that restarts the engine; logs and problem report. English, Türkçe, Русский, فارسی, العربية (Persian and Arabic are new: corrections welcome). Material You, light and dark.

How it works Many providers recognise blocked sites by reading the first packets of a connection (the domain name in the TLS handshake). ByeDPI changes how those packets look, so the filter does not recognise them, while the site still understands them.

DPIMech uses Android's VpnService only to catch the chosen apps' traffic on the phone and hands it to ByeDPI through hev-socks5-tunnel.

Not a VPN service. Every connection still goes straight to the site. Nothing passes through anyone else's server, and your IP address is not hidden. Sites blocked by IP address stay blocked. No local trick helps there. One VPN at a time. Android allows only one, so another VPN or a VPN-based ad blocker cannot run together with DPIMech.
