VLESS+Reality protocol — traffic indistinguishable from HTTPS. Bypasses Iran DPI. DNS-over-HTTPS prevents ISP poisoning. AI selects the fastest working route. 1 GB free. No account.
Not a generic VPN. Every protocol choice, every SNI, every DNS server is chosen specifically to work under Iran's DPI infrastructure.
VLESS + Reality Protocol
Traffic is cryptographically indistinguishable from a normal TLS 1.3 handshake to a legitimate domain (e.g. www.microsoft.com). Iran's DPI cannot identify it as a VPN.
AI Protocol Fallback
When Reality is blocked on a specific ISP, the app automatically switches to XHTTP or WebSocket over nginx. Tests run in parallel — no manual configuration.
DNS-over-HTTPS
DNS queries go through the encrypted VPN tunnel using DoH (1.1.1.1, 8.8.8.8, 9.9.9.9). ISP DNS poisoning — a common technique in Iran — cannot intercept or redirect your queries.
Remote SNI Updates
When Iran blocks a new SNI, updated priority lists are pushed to all apps without requiring an update. You get the fix automatically within minutes.
FAQ
Iran VPN — Common Questions
Real answers about VPNs, censorship, and how SetaLink works in Iran.
SetaLink uses VLESS+Reality protocol which makes VPN traffic indistinguishable from normal HTTPS traffic to trusted domains. Unlike older VPN protocols (OpenVPN, WireGuard, Shadowsocks), Reality cannot be identified by Iran's DPI infrastructure. It's free, requires no account, and uses AI to select the fastest working route for your ISP.
Iran uses Deep Packet Inspection (DPI) at ISP level to identify and block known VPN protocols. Protocols like OpenVPN or WireGuard have distinct handshake patterns. VLESS+Reality was designed specifically to be indistinguishable from standard TLS 1.3 — it mimics a browser connecting to a legitimate site like www.microsoft.com.
Yes. SetaLink maintains per-ISP SNI success data and adapts its routing accordingly. The AI optimizer knows which SNIs and protocols have the highest success rate for each Iranian carrier, and updates these lists via Remote Config when blocking patterns change.
Iranian ISPs poison DNS responses for blocked domains — returning fake IPs or NXDOMAIN. SetaLink routes all DNS queries through the encrypted VPN tunnel using DNS-over-HTTPS (DoH), preventing ISP interception. Fallback resolvers (1.1.1.1, 8.8.8.8, 9.9.9.9) ensure DNS always resolves correctly.
SetaLink uses the Xray-core engine internally, but adds: AI-powered protocol selection, real HTTP probe validation (not just TCP), remote config updates, referral data bonuses, and a simple Android UI. V2Ray/Xray are server software — SetaLink is a complete managed service.
Iranian law prohibits using unauthorized VPNs. We do not provide legal advice. Many Iranians use VPNs as a practical necessity to access information. Make your own decision based on your circumstances.
