For those who prefer manual installation or want to access specific release versions, DevToys provides downloadable packages on GitHub. Users can download the latest release from the GitHub repository and follow the installation instructions provided.

Package Managers

DevToys supports package managers like WinGet and Chocolatey, offering a convenient command-line installation option for power users. Users can install DevToys using the respective package manager commands:

  • WinGet: winget install DevToys
  • Chocolatey: choco install devtoys


Once installed, DevToys offers multiple ways to access its functionalities:

Start Menu

Users can simply navigate to the Windows start menu, type "DevToys," and press Enter to launch the application.


DevToys enthusiasts will appreciate its command-line capabilities. By opening a PowerShell command prompt and typing start devtoys:?tool={tool name}, users can directly access specific tools within DevToys. For example, start devtoys:?tool=jsonyaml will open DevToys with the JSON to YAML conversion tool selected.

Privacy and Security

In an era where data privacy and security are paramount concerns, DevToys prioritizes user trust and confidence. The application works entirely offline, ensuring that none of the data processed by the app is transmitted over the internet. However, certain tools within DevToys may require elevated system permissions to function optimally. For instance, tools like PNG/JPEG compressor and color picker may utilize third-party Win32 processes, necessitating permissions to access system resources. Users can rest assured that all code requiring elevated permissions is open-source and transparently accessible on GitHub.

Community and Contributions

DevToys thrives on community collaboration and contributions. Developers are encouraged to actively participate in the project by submitting bug reports, feature requests, or even contributing code. The CONTRIBUTING guidelines provide detailed instructions on how to contribute effectively to the project, ensuring a seamless and inclusive development process.

Transparency and Accountability

Transparency is a core value upheld by the DevToys team. The project adheres to stringent privacy policies outlined in the PRIVACY POLICY, ensuring user data is handled responsibly and ethically. Additionally, DevToys utilizes various third-party libraries and tools, each accompanied by comprehensive notices and attributions in the ThirdPartyNotices section.

Licensing and Redistribution

DevToys operates under a flexible license that permits redistribution of the application as trialware or shareware. However, the creators encourage users to refrain from altering or redistributing the application without prior consultation. Users are encouraged to reach out to the authors if they have compelling reasons for deviation from the standard licensing terms.


DevToys owes its success to the collective efforts of numerous contributors and designers. The project is immensely grateful to individuals who have dedicated their time and expertise to enhance the platform's functionality and aesthetics. Special thanks to code contributors and designers like Jakub for their invaluable contributions to the project.


In the fast-paced world of software development, tools like DevToys are invaluable assets, simplifying complex tasks and empowering developers to focus on innovation. With its comprehensive toolkit, offline functionality, and commitment to privacy and transparency, DevToys stands as a beacon of efficiency and convenience in the developer community. Whether you're a seasoned developer or just starting your coding journey, DevToys promises to be your trusted companion, simplifying your development workflow one task at a time.
