OUI/MAC Lookup Offline

MAC Lookup Offline: Essential OUI/MAC Vendor Lookup Tool for Network Engineers

Find the company behind any MAC address instantly—even without internet. MAC Lookup Offline ships with a built‑in OUI database, smart search, and field tools for network engineers, field techs, and help desks. It is the ultimate network tool for on-site triage and incident response. Privacy‑first. No ads. No tracking.

What you can do:

• Offline OUI/MAC Search: Look up by full MAC, OUI, vendor name, address, or country. The entire database is available without connectivity.


• Live Camera OCR: Capture MACs from device screens/labels; “Snap” for high‑accuracy file OCR. Images saved to Pictures/MACLookup.


• Voice Input: Speak a MAC or vendor; we normalize and search automatically.


• Network Analysis & Files: Ingest large log/lease text files (≈100MB), extract and de‑duplicate MAC addresses, and summarize results by vendor.


• Reports: Generate Top Vendors and All MACs reports (sortable) for fast triage and sharing.


• Advanced Exports: Export data in multiple formats: CSV, JSON, XML, or a responsive, sortable HTML report (share/email).


• API Export (Pro): Post data to your endpoint with method, headers, and Bearer token. Includes optional SSL‑ignore for lab scenarios.


• Smart Filtering & Data Management: OR‑filter chips, configurable page sizes, and OUI database updates with a validate & diff preview feature.


• Themes: Light/Dark themes and customizable layouts for fieldwork.

Free vs Pro
The Free version is a full app with a 15‑item display/export cap (totals still shown). The Pro (one‑time purchase) unlocks unlimited results, Files & Reports, full Camera OCR power features, and API export.

Why it’s different:

• Works Offline: Designed for air‑gapped or low-connectivity environments.


• Private by Design: No ads or analytics SDKs. Network is used only when you choose to update the database or export data.


• Built for Speed: Fast local search, client‑side pagination, and instant lookups.

Who it’s for:
Network engineers, help desks, field techs, installers, inventory, auditing, and incident response teams.
