BatCave Monitor

A private desktop resource cockpit that tells you which workload is making the machine slow—and what data it cannot see.

Preview releases Source code Telemetry coverage

Status: Public preview
Runs on: Windows, Linux, and macOS
Built with: Rust, Tauri, and Svelte
License: MIT

The current native BatCave interface with live Windows telemetry.

Overview

What it is

BatCave Monitor is a local-first desktop resource cockpit for the moment when a computer feels slow and the usual graphs do not explain why.

It joins system pressure to the workloads behind it, then makes the quality of every reading explicit. When the operating system withholds a metric, BatCave says so and keeps the rest of the view useful.

Current main supports native collectors and bundles for Windows, Linux, and macOS. The public preview release is older and currently offers Windows and Linux downloads; macOS is still a source or local-build path until a notarized release is published.

Capabilities

What it does

01
Explains the slowdown
Connects CPU, memory, disk, and network pressure to the workload most likely to be causing it.
02
Keeps triage readable
Groups and ranks processes while keeping the list stable enough to inspect live data without chasing rows.
03
Lets you inspect the cause
Shows overview, resource, technical, and history views for the selected workload or system resource.
04
Names what it cannot see
Explains missing or permission-limited telemetry instead of turning unavailable data into a convincing zero.
05
Works like a desktop tool
Includes sampling controls, themes, compact layouts, privileged-access guidance, and local-data reset.
06
Stays local
Reads native platform telemetry and keeps settings, snapshots, logs, and measurements on the machine.

Why I built it

A computer can be obviously struggling while the usual charts leave the diagnosis to you. I wanted one view that connects pressure to the workload behind it, without uploading a stream of machine telemetry somewhere else.

BatCave is opinionated about uncertainty. If a collector is permission-limited or a platform cannot provide a metric, the interface explains the gap instead of turning missing data into a confident zero.

Where it stands

Current source supports native Windows, Linux, and macOS collectors, compact and full layouts, local diagnostics, and platform bundles. The public prerelease is older and currently offers Windows and Linux downloads.

A notarized public macOS release and the remaining signing and installer proof are still release work. The repository documents those limits directly.
