A privacy-first, zero-cloud network monitoring CLI + Web Dashboard for small offices, homelab and security research.
面向小型办公室、Homelab 与安全研究的隐私优先、零云端依赖的网络监控 CLI 与 Web 仪表盘。
Python 3.11+ Platform FastAPI Typer Tests License: MIT Version PRs Welcome GitHub stars
WifiMap is a self-hosted, privacy-first network observability tool that turns any workstation (macOS / Linux / Windows) into a passive sensor for a small office or homelab LAN (~40 devices). It continuously discovers devices through ping sweep + ARP + mDNS + BLE, stores everything in a local SQLite database, and exposes the data through a rich Typer CLI and a local FastAPI Web Dashboard.
No cloud. No telemetry. No external dependencies. Your data never leaves the LAN.
- 🔍 See every device the moment it joins the network — wired, wireless, IoT, BLE beacons, even AirTags.
- 🛡️ Audit your own LAN with built-in nmap port scanning and a default-credential probe (9 vendor families).
- 🕒 Spot anomalies with
(weekday ×ばつ hour)baselines — get notified when an unexpected device shows up at 3 AM. - 🔒 Automate physical security — auto-lock your Mac when your phone leaves the office, auto-check-in when it returns.
- 🥷 Stay invisible — fully passive mode (ARP + mDNS listen only, no ICMP).
- 🧠 Smart device fingerprinting — IEEE OUI vendor DB + mDNS service hints + hostname keywords + user tag feedback loop (>95% accuracy).
- 📡 BLE-aware — detects AirTag-style trackers, persistent strangers, and supports a GATT Lab for advanced experiments.
WifiMap 是一款自托管、隐私优先的网络可观测性工具,可将任意一台工作站(macOS / Linux / Windows)变成小型办公室或 Homelab 局域网(约 40 台设备规模)的被动感知节点。它通过 ping 扫描 + ARP + mDNS + BLE 持续发现设备,将所有数据存入本地 SQLite,并通过功能丰富的 Typer CLI 和本地 FastAPI Web 仪表盘呈现。
无云端、无遥测、无外部依赖,所有数据永不离开你的 LAN。
- 🔍 看见每一台设备 — 有线、无线、IoT、BLE 信标,甚至 AirTag,加入网络的瞬间即可被识别。
- 🛡️ 审计自己的局域网 — 内置 nmap 端口扫描和 9 大厂商默认凭据探测。
- 🕒 发现异常行为 — 按「星期 ×ばつ 小时」学习基线,凌晨 3 点出现陌生设备立即告警。
- 🔒 自动化物理安全 — 手机离开办公室自动锁屏 Mac、回到办公室自动签到。
- 🥷 隐身模式 — 完全被动扫描(仅监听 ARP + mDNS,不发送 ICMP)。
- 🧠 智能设备指纹 — IEEE OUI 厂商库 + mDNS 服务提示 + 主机名关键字 + 用户标签反馈闭环,识别准确率 >95%。
- 📡 蓝牙感知 — 检测 AirTag 类追踪器、长期驻留陌生设备,并支持高级 GATT 实验室功能。
