# WattSeal

> The world's first real-time PC power consumption monitor with per-application and per-component breakdown.

WattSeal is a free, open-source desktop application built in Rust that shows users exactly how much electricity each application on their PC consumes — in real time, in watts, in cost, and in CO₂ emissions.

## What WattSeal Does

- **Real-time power monitoring**: Displays total PC power consumption in watts, updated live.
- **Per-application breakdown**: Shows exactly which apps use the most power, cost, and carbon.
- **Per-component breakdown**: Measures CPU, GPU, RAM, storage, and network individually.
- **Carbon footprint tracking**: Converts power usage to CO₂ based on local grid carbon intensity. Users can choose their region's carbon intensity for accurate results.
- **Electricity cost estimation**: Calculates real electricity cost per app, per session, and over time.
- **Time-averaged history**: View data in real-time, 1-minute, 1-hour, or custom time ranges.
- **Direct database access**: All data stored in a local SQLite database for custom queries and integrations.
- **Plain-language UI**: Every metric explained in simple terms — no technical knowledge required.

## Key Differentiators

- **Per-app power attribution**: No other tool maps hardware power draw to individual applications.
- **Cross-vendor**: Works with AMD, Intel, and NVIDIA hardware simultaneously.
- **Built in Rust**: Near-zero system overhead — the monitor itself barely uses any power.
- **100% private**: All data stored locally. No cloud, no tracking, no telemetry.
- **Open source**: GPLv3 licensed, fully auditable on GitHub.
- **Multilingual**: Available in English and French, with more languages planned.
- **Adaptable carbon intensity**: Users select their local electricity grid's carbon intensity for region-accurate CO₂ tracking.

## How It Works

WattSeal runs a lightweight background daemon that reads hardware telemetry via RAPL (Intel/AMD CPUs), NVML (NVIDIA GPUs), and ADLX (AMD GPUs). It uses kernel-level process accounting to attribute system-wide power draw to individual applications proportionally. Data is surfaced via fast IPC to a clean desktop UI.

## Supported Platforms

- Windows (single .exe file)
- macOS (single binary)
- Linux (single binary)

## Target Users

- Gamers wanting to understand power draw per game
- Remote workers tracking home office electricity costs
- Environmentally-conscious users monitoring their carbon footprint
- IT administrators managing fleet energy consumption

## Comparison

WattSeal vs Task Manager: Task Manager shows CPU %, not watts. It cannot attribute power to apps.
WattSeal vs HWiNFO: HWiNFO reads hardware sensors but doesn't map readings to software processes.
WattSeal vs GPU-Z: GPU-Z is limited to GPU only.
WattSeal vs MSI Afterburner: Afterburner provides overlays but doesn't show per-app electricity cost.

## FAQ

Q: How much electricity does an average PC use per year?
A: 200–1000 kWh, costing €30–€180 in Europe.

Q: Does WattSeal itself use significant power?
A: No. Built in Rust with near-zero overhead.

Q: Is WattSeal free?
A: Yes, 100% free and open-source (GPLv3).

Q: Does WattSeal send data to the cloud?
A: No. All data stays local. No telemetry, no tracking.

Q: What languages does WattSeal support?
A: English and French, with more languages coming soon.

Q: Can I customize the carbon intensity for my region?
A: Yes. WattSeal lets you choose your local grid's carbon intensity for accurate CO₂ calculations.
