Core Features

Everything You Need to Manage Licenses

From activation tracking to subscription lifecycle management, License Viewer puts you in full control.

Activation Licenses

Track every activation against your subscriptions. See which computers and users are consuming seats, when they last activated, and diagnose failed activations instantly.

Consumable Features

Monitor API call usage against plan limits with daily call counts, projected monthly totals, and automatic threshold alerts at 80% and 100% of your allocation.

Live Dashboard

See orders, active users, upcoming renewals, and six-month usage trends at a glance. A subscription expiry gauge keeps renewals on your radar.

User & Access Control

Revoke access, blacklist or deactivate users directly from the app. Get a full audit trail with machine details and timestamps for every activation.

Subscription Lifecycle

Track subscriptions end-to-end: order dates, expiry, seat counts, products, and contacts. Batch-edit, assign discount coupons, and manage cloud tiers.

Role-Based Access

Support multiple user roles with Admins getting full management tools and Viewers getting read-only dashboard access. Switch linked accounts seamlessly.

Industry-Leading Security

Built Secure from the Ground Up

Every layer of License Viewer is engineered with security as a first principle, running on a modern cloud-native architecture.

JWT + Refresh Token Auth

Secure token-based authentication with automatic refresh, ensuring sessions stay protected without user friction.

HMAC-Authenticated SDK API

External API calls are secured with HMAC signatures, preventing tampering and ensuring request integrity.

Azure Cloud Infrastructure

Hosted on Azure Functions for serverless scalability with Azure Table Storage for reliable, geo-redundant data persistence.

Sentry Error Monitoring

Real-time error tracking and monitoring ensures issues are caught and resolved before they impact your business.
