A free VPN app for Android. Open-source client, transparent infrastructure. Watch an ad, get 60 minutes of full-speed traffic — no accounts, no logs, no subscriptions.

How it works

Watch a short rewarded ad
Server creates a temporary VLESS session (60 min / 4 GB)
Your traffic routes through a single server in Finland
When data runs out, you're throttled to 1.5 Mbps instead of cut off
Session expires — watch another ad or move on

No email. No password. No payment. The ad pays for the server.

Protocol

Transport — VLESS over XHTTP (HTTP/2 multiplexed, path-hidden behind /revolt)
Obfuscation — Xray Reality spoofs www.github.com TLS. To any DPI box, your tunnel looks like a browser visiting GitHub
Encryption — TLS 1.3 with borrowed certificate (Reality). No certbot, no domain ownership required
API — Standard HTTPS to a separate domain. Tunnel destination is IP-pinned — domain compromise is DoS only

Stack

Layer	Technology
App	Flutter (Android)
VPN	VLESS + Xray Reality + XHTTP
Backend	Python Flask ("Hivemind") — session management, quotas, stats

Server	Debian, single Hetzner box in Finland

Limitations

One server, one location (Finland)
2 vCPU / 4 GB RAM — not built for thousands of concurrent users
Android only

Privacy

Your traffic routes through Finland. We don't log it, inspect it, or sell it. Hivemind tracks only session liveness and byte counters for quota enforcement — no packet contents, no destination IPs, no DNS queries.
