Unlike traditional VPNs, Postern gives you fine-grained control over what traffic is routed where. This is perfect for developers, sysadmins, and testers who want to proxy only certain APIs, domains, or services - without affecting the whole device.
Postern works best with stable, authenticated HTTP or SOCKS5 proxies like those from RapidSeedbox. These are ideal for routing API traffic, scraping with mobile apps, or accessing region-locked platforms with high uptime and low latency.
In regions where VPN apps are restricted, Postern lets you bypass censorship using pure proxy transport. RapidSeedbox proxies work as drop-in endpoints, helping you avoid DPI and blocklists while preserving high-speed access.
Open Postern on Android, tap Profiles > Add Proxy, and choose your proxy type: SOCKS5, HTTPS, or Shadowsocks. Input the IP, port, and authentication details from your RapidSeedbox account. Name and save the profile.
Go to Rules > Add Rule. You can create domain-based, IP-based, or port-based rules to route specific traffic through your proxy. For example, direct only gaming traffic, specific apps, or blocked domains through your proxy tunnel.
Switch to your saved proxy profile and toggle "Start Routing". Postern uses Android’s VPN service to tunnel traffic system-wide. You can set rules for global proxying or per-domain/app targeting - great for debugging, scraping, or geo-unblocking.

Postern supports SOCKS5, HTTPS, and Shadowsocks. RapidSeedbox proxies work with both SOCKS5 and HTTPS for most routing use cases.
Yes and no. Postern uses Android’s VPN service to route traffic, but it doesn’t encrypt traffic like traditional VPNs. It gives proxy-level routing control instead of full-tunnel encryption.
Yes. Postern lets you create custom rules by domain, IP range, or port. This lets you target only specific services while leaving others on your direct connection.
Yes. When adding a new proxy, enter your RapidSeedbox username and password. Authenticated proxy sessions are supported for all types except Shadowsocks.
For developers or testers, yes. Postern lets you selectively route traffic, swap IPs per rule, and avoid the overhead of full-tunnel VPNs. It’s ideal for mobile scraping, load testing, or network inspection.
