Introduction

Celer is an app for Windows 10 & 11 with the purpose of giving you back control of your system. The app is structured into modules that contain various features that help you maintain your machine optimized.

Features

• Real time monitoring of system information (CPU, Memory, GPU, sensors, battery, drives).
• Cleaning of temporary files generated by the system and third party apps.
• Manage power plans (currently limited) and view battery wear.
• View memory stats (physical and virtual memory, and each slot both active and empty).
• View GPU information with support for system with 2 or more GPUs.
• Easily run the official Windows repair tools.
• Quick network status information and simple system-wide DNS changer.
• Evaluate the system's privacy and security level.

Requirements

• Windows 10 (build 18362 or higher) or 11 x64
• Minimum of 300MB of available RAM *
• Minimum of 100MB of free disk space
• .NET Runtime 10 (x64) must be installed

* Due to the nature of .NET and other factors, Celer memory usage may reduce/increase with usage.

Installation

We currently only provide x64 binaries and setup files for Celer but x86 and portable packages are planned when we reach a stable release.

The setup is hosted on GitHub and can be downloaded either through GitHub Releases or through Celer's page on SurfScape.

Roadmap

• Support for third-party maintenance tools (ex: AdWare Cleaner, TRON Script, Snappy Driver Installer Origin).
• Winget frontend with bulk installing and updating.
• Process and power management utilities that leverage hidden Win32 APIs.
• Multi-language support.
• Add-in system.
• Additional themes.

Building

Celer is developed and built using Visual Studio Community 2026 and the .NET 10 SDK under a Windows 11 Pro laptop. For development and testing purposes it's important to have a fully up to date Windows 11 Pro environment, it's also recommended to have a similar environment on a Windows 10 machine (or VM) since Celer does have official Windows 10.

Building Solution

dotnet build

Running Solution

Do note that Celer requires admin privileges and as such the following command will only work on an eleveated terminal.

dotnet run
