* docs(api): document WireGuard and mtproto secret generation on clients/add The POST /panel/api/clients/add summary enumerated the protocols whose secrets the server fills in, and that list stopped being complete when WireGuard gained per-client keys and mtproto gained a FakeTLS secret. Read literally it says the endpoint is unusable for WireGuard without a hand-made keypair and address, while defaultWireguardClients in fact generates the keypair, derives the public key from a supplied private one, and allocates a free /32. Rather than extend an enumeration that goes stale on every new protocol, the summary now states the rule alone and the per-protocol detail moves into the operation description - a field Endpoint already declares and build-openapi.mjs already maps, but that no endpoint used until now. Swagger UI in the panel and the docs site both render it. The attach operation gets the rule added for #5785 that nothing documented: a client already carrying allowedIPs brings them into the new inbound instead of being given a fresh address, and is rejected when another client of that inbound holds it. Closes #6276 * docs(api): correct the clients/add generation rules flagged in review Three claims in the new description did not hold: Shadowsocks does not keep every supplied password. fillProtocolDefaults regenerates it when validShadowsocksClientKey rejects it, which on a 2022-blake3-* inbound means any password that does not base64-decode to 16 or 32 bytes - the call still returns success, so the caller has to read the client back to notice. Split off from Trojan and spelled out. The UUID is not always fresh: re-adding an email that already exists, with the stored subId, reuses the stored id, password, auth and secret so the identity stays in sync across its inbounds. That branch was documented nowhere. The mtproto secret falls back to www.cloudflare.com when the inbound carries no fakeTlsDomain.
3x-ui Documentation
The official documentation and product site for 3x-ui — an advanced web panel for managing Xray-core servers.
Overview
This directory (docs/ in the 3x-ui monorepo) contains
the source for docs.sanaei.dev — a static-first documentation and
marketing site built with Fumadocs on Next.js. It has no backend,
no database, and no auth: every page is prerendered and every tool runs entirely in the
browser.
What's inside
The documentation walks you through 3x-ui from first install to day-to-day operation:
- Getting Started — installation, first login, and updating or uninstalling the panel.
- Configuration — the panel, inbounds, REALITY, transports, clients, subscriptions, and share links.
- Operations — reverse proxy, multi-node setups, outbounds & routing, backup/restore, the Telegram bot, and security.
- Reference — environment variables, the database, ports & firewall, and the HTTP API.
- Help — troubleshooting, FAQ, migration, and how to contribute.
Interactive tools
The site ships with in-browser helpers that generate configuration for you — no data ever leaves your browser:
| Tool | What it does |
|---|---|
| REALITY Config Generator | Build a valid REALITY inbound configuration. |
| Share Link Inspector | Decode and inspect vless:// / vmess:// share links. |
| Install Command Builder | Assemble the right install command for your setup. |
| Reverse Proxy Generator | Generate reverse-proxy configs (Nginx / Caddy). |
| Protocol Wizard | Pick and configure the right protocol for your needs. |
| Firewall Rules Generator | Produce firewall rules for your ports. |

Quick start
This project uses pnpm (npm lockfiles are gitignored). Run everything
from the docs/ directory:
cd docs
pnpm install
pnpm dev # http://localhost:3000
Useful scripts:
| Script | Description |
|---|---|
pnpm dev |
Start the dev server |
pnpm build |
Production build (also typechecks) |
pnpm typecheck |
Generate MDX/route types and tsc --noEmit |
pnpm lint |
Run oxlint (.oxlintrc.json) |
pnpm test |
Run unit tests (Vitest) |

Project structure
app/ # Next.js App Router — layouts, home, docs, OG images, search, llms.txt
components/ # React components — interactive tools, home sections, MDX bindings
content/docs/ # MDX documentation, one folder per locale (en · fa · ru · zh)
lib/ # source config, i18n, GitHub stats, and the unit-tested lib/xray logic
public/ # static assets — logos, favicon, openapi.json, CNAME
scripts/ # build-time scripts (API reference generation)
source.config.ts # Fumadocs MDX schema & collection config
next.config.mjs # Next.js config (static-export gating)
proxy.ts # i18n middleware
Internationalization
Documentation is authored in English. Persian (fa, RTL), Russian (ru), and
Chinese (zh) locales are wired up; untranslated pages fall back to English so they
never 404. English URLs are unprefixed; other locales live under /fa, /ru, /zh.
Deployment
The site builds for two targets:
- Vercel / Node —
pnpm build(static search index + prerendered OG images). - GitHub Pages (static export) —
DEPLOY_TARGET=static pnpm build→out/.
