Custom VPN App Development

Mon, 01 Jan 0001 00:00:00 +0000

What you get

A VPN app is the visible part of a much larger system. We build the whole thing: the native client your users tap, the admin panel you run the business from, the billing and subscription flow, the servers, and the protocol engineering that keeps connections fast and reachable.

Because we build the clients in-house, including native iOS (NetworkExtension) and Android (VpnService), you are not stitching together a generic SDK and hoping it behaves. The apps, the panel, and the infrastructure are designed to work together.

IPLogs

Mon, 01 Jan 0001 00:00:00 +0000

What IPLogs is for

IPLogs answers one question fast: is this IP a VPN, proxy, or Tor exit, and how risky is it? Paste any IPv4 or IPv6 address, or check your own, and get a clear verdict plus a 0 to 100 threat score, backed by the network identity, geolocation, and routing behind it.

How it decides

Rather than trusting a single blocklist, IPLogs runs a 7-layer pipeline across 13 intelligence sources, including IP reputation data, ASN and BGP analysis, Shodan, active probing, fingerprinting, and client telemetry. It also flags datacenter ranges, Apple Private Relay, and Cloudflare WARP.

TunnelHQ

Mon, 01 Jan 0001 00:00:00 +0000

What TunnelHQ is for

Running a VPN means running servers, and a server can answer a ping while quietly failing to carry VPN traffic. TunnelHQ does real protocol handshakes, not just pings, so you know each server is genuinely up for the protocol your users connect with. It watches your whole fleet in real time and tells you the moment something breaks.

Built for teams who run VPN fleets at scale

Monitors the full modern stack: WireGuard, OpenVPN, IKEv2, OpenConnect, Shadowsocks, VLESS, VMess, Trojan, Xray, Hysteria2, TUIC, and AmneziaWG.
Continuous, independent per-server checks with live latency, uptime, and health history.
Incidents, alerting, and analytics built for teams, not just a single admin.
API, CLI, and integrations so it fits the way you already work.
A free tester to check a single server, and a free trial to monitor your fleet.

We run it ourselves

TunnelHQ monitors our own VPN infrastructure. It is not a side project; it is how we keep services up.

VPN QA & Test Automation

Mon, 01 Jan 0001 00:00:00 +0000

Why VPN apps need their own QA

A VPN app can pass an ordinary test suite and still leak. The failure modes that matter most for a VPN are specific: a kill switch that does not engage on an abrupt drop, DNS escaping the tunnel, IPv6 traffic going in the clear, or a client that fails to reconnect cleanly after a network change.

We test for those directly, on real devices, across the platforms your app ships to.

VPN Support & Managed Ops

Mon, 01 Jan 0001 00:00:00 +0000

After launch is where VPNs are won or lost

The hard part of a VPN business is not shipping version one. It is keeping a fleet of servers reachable across regions, staying ahead of OS and app store changes, and responding when a region goes dark at 2am. Managed ops is how you run a VPN product without building an in-house infrastructure team on day one.

What we run for you

Server fleet: provisioning, scaling, patching, and decommissioning across regions.
DevOps: deployment pipelines, configuration, and infrastructure as code.
Monitoring: multi-region connectivity and uptime through TunnelHQ, with alerts to your channels.
Incident response: a defined process for detection, communication, and recovery.
Maintenance: protocol, OS, and store changes kept current so nothing rots.

Built on what we use

We monitor your fleet with the same product we build and run ourselves, TunnelHQ. The tooling is not a side project; it is how we operate.
