NoMoreBorder

NoMoreBorder is a utility designed to enhance your multitasking experience by enabling any windowed application to run in a fullscreen borderless mode without changing the screen resolution. This software is perfect for certain scenarios where applications don't have a dedicated full-screen borderless mode and running it fullscreen would mess up with dual screen behaviours.

Features

1. Borderless Fullscreen: Make any windowed application run in fullscreen mode without the traditional window borders, providing an immersive experience without altering the screen resolution.
2. Custom Resolution: Have a big screen and an old game made for small screens and low resolutions where windowed mode is too small but fullscreen is so big you barely read the dialog? Now you can also set a custom resolution.
3. Multiple Monitor Support: Ability to select which monitor you want the window to be on.
4. Reversible Action: Easily revert any changes made to the window, restoring the original windowed mode with borders.
5. Session Memory: NoMoreBorder remembers which applications were set to borderless mode, automatically reapplying these settings in future sessions. It's done through a configuration file, ensuring a seamless experience even after restarting the software or your computer.
6. Dark Mode: Includes a built-in dark mode, allowing for an on-the-fly theme switch to reduce eye strain during late-night sessions.
7. Start with Windows: Now offers the option to auto start with your system, to save you a few clicks!

Getting Started

Option 1. Download stand-alone exe

Just download the NoMoreBorder.exe from releases, and run it as it is. No need to setup dependencies, everything is included in this binary executable.

Note: For the best experience, it's recommended to run NoMoreBorder with administrative privileges. This ensures that the application can properly interact with other software windows on your system.

or, Option 2. Run as a script / Compile your own exe

You can run it as a python script or compile your own exe, I used pyinstaller. Ensure you have Python installed on your system along with the necessary packages: customtkinter, pywin32, pyinstaller, screeninfo, pystray, win11toast, and pillow. These can be installed using pip:

pip install -r requirements.txt

Running NoMoreBorder

To run NoMoreBorder, simply execute the Python script from your terminal or command prompt:

python main.py

To compile, simply put this command in your terminal or command prompt:

pyinstaller NoMoreBorder.spec

You will find the exe in dist folder in parent directory.

⚠️ Antivirus False Positives Notice

Some users have reported that certain versions of NoMoreBorder are being flagged by antivirus software (such as Windows Defender, Norton, and Bitdefender) as potential malware. These are false positives, primarily due to how compiled Python applications behave and the fact that the tool interacts with system-level window management (e.g., modifying window states, adding to startup registry).

To ensure full transparency:

• The app is open source – you’re encouraged to review the code and compile it yourself from main.py if you'd like complete peace of mind.
• We've transitioned to using GitHub Actions to compile releases in a clean and controlled environment, reducing the risk of local environment contamination.
• Recent builds have been tested with VirusTotal and show significantly fewer detections after refining the build process (e.g., now building our own pyinstaller bootloader while compiling binary).
• We're actively submitting these false positives to antivirus vendors for whitelisting.

We appreciate your patience and understanding. False positives are unfortunately common with Python-based tools that are compiled to .exe files.

Configuration

NoMoreBorder automatically saves your settings to a settings.json file located in the Documents/NoMoreBorder directory. This file includes the list of applications set to borderless mode and the selected theme, ensuring your preferences are maintained across sessions.
