Frequently Asked Questions
What is HiddenIO?
HiddenIO is a public directory of V2Ray-compatible VPN configurations collected from approved public sources. We organize configs by country, ISP, and protocol for easy browsing.
Is HiddenIO free?
Yes, HiddenIO is completely free to use. All configs are from publicly available sources.
How do I use a subscription link?
Copy the subscription URL, open your V2Ray client (like v2rayNG or V2RayN), add a new subscription, paste the URL, and update. Then select a config and connect.
How are configs scored?
Configs are scored using non-connectivity metadata: source reputation, freshness, format completeness, and how many sources carry the same config.
Does HiddenIO test configs?
No. HiddenIO never tests, probes, or connects through collected configurations. We only parse and normalize the data.
How often are configs updated?
Configs are fetched from sources automatically every hour. Freshness scores indicate how recent each config is.
What protocols are supported?
We support VLESS, VMess, Trojan, and Shadowsocks configurations.
How do I scan a QR code?
Open your V2Ray client's QR scanner, point it at any QR code on HiddenIO, and the config will be imported automatically.
