systeminformer
A free, powerful, multi-purpose tool that helps you monitor system resources, debug software and detect malware. Brought to you by Winsider Seminars & Solutions, Inc. @ http://www.windows-internals.com
The Lens
System Informer is what Windows Task Manager should have been. It shows every process, thread, DLL, network connection, and service on your machine with real-time graphs and drill-down detail that Microsoft's built-in tools never bothered to provide. This is the successor to Process Hacker, rebuilt from the ground up.
No installation required. It runs portable from a USB stick. You get per-process CPU, memory, disk, and network breakdowns. Kernel-mode stack traces and .NET process inspection are built in. You can see exactly which process is holding a file lock. The plugin system lets you extend it.
Developers debugging performance issues on Windows need this. Sysadmins diagnosing rogue processes need this. Security researchers analyzing malware behavior need this. It replaces Task Manager, Resource Monitor, and most of Sysinternals Process Explorer in a single tool.
The catch: Windows only, local only. No remote monitoring, no fleet management, no centralized dashboard. Monitoring servers across a network requires something else entirely.
Free vs Self-Hosted vs Paid
fully freeFree Tier
Everything. MIT licensed, no restrictions. Full feature set including kernel-mode inspection and plugin system.
Self-Hosted

Paid Alternatives
Process Explorer (Sysinternals, free from Microsoft but less capable). For fleet monitoring: Datadog ($15/host/mo), New Relic, Dynatrace ($21/host/mo). System Informer is a local diagnostics tool, not a monitoring platform.
