Installation guide
Install the package for your operating system, launch Mongrel, then use the built-in trial or your customer portal license key.
1. Choose the right installer
Open the download page and choose the package matching your operating system and CPU architecture.
Windows: x64 or ARM64 .exe and .msi installers.
macOS: Apple silicon (ARM64) .dmg.
Linux: x86-64 .deb, .rpm, or AppImage.
2. Install the package
Use the normal installer flow for your operating system. For Linux package formats, install with your distribution package manager so runtime dependencies can be resolved.
For AppImage files, mark the file executable before launching it.
For .deb and .rpm packages, let the package manager install dependencies.
If a Linux desktop keychain prompt appears, allow it so saved connections can use the OS keychain.
3. Launch Mongrel
At first launch, accept the license terms and choose Start 7-day free trial in the activation dialog. The trial is issued once per machine through the licensing service.
4. Activate after purchase
After buying a plan, sign in to the customer portal, open License, copy the key, then activate inside Mongrel.
