Node link parser and QR code

A vless:// or trojan:// link packs every connection parameter into one string. This tool breaks it into readable fields and generates a QR code to move the node to your phone. The data never leaves your browser.

What the fields mean

Server and port are where to connect; UUID or password is your access key (never share it); SNI is the domain named in the TLS handshake; pbk and sid are Reality parameters; type is the transport (tcp, ws, grpc). The background is in what is VLESS.

Why a QR code

iPhone and Android clients (Streisand, v2rayNG, Hiddify, Shadowrocket) import a node by scanning. Point the app's camera at the code and the node appears in the list without copying anything.

Safety

Parsing happens entirely in your browser: the link is not sent to any server and is not stored. Secret fields stay hidden until you press "show".

Tired of copying links?

In the 404 VPN app the server list is built into your account: sign in and connect, no links or subscriptions. Same protocol: VLESS.

Frequently asked questions

guest@404vpn:~$ cat node-link-parser-faq.md

[01] $ My subscription does not parse ▸

> The tool understands base64 subscriptions containing a list of links. Clash (YAML) and sing-box (JSON) subscriptions must be opened in the client itself. If the link is truncated or contains spaces, copy it again.

[02] $ Should I worry about allowInsecure or insecure? ▸

> If they equal 1, the client does not verify the server certificate and the connection can be intercepted. A trustworthy node omits them or sets them to 0.

[03] $ Does the tool change the link? ▸

> No. "Copy link" copies the original string unchanged.
