Download & run

Golavo runs on your computer in all three modes. There is no hosted forecasting service and no account requirement.

Run in your browserSource mode for macOS, Windows, or Linux

Download for macOSApple Silicon DMG from the latest stable release

Download for Windowsx64 EXE or MSI from the latest stable release

The website download section detects macOS or Windows and turns the desktop buttons into direct links to the matching asset in the newest stable GitHub release. If GitHub’s API is unavailable, the buttons safely fall back to the release page instead of guessing a filename.

Both desktop downloads are produced by the same release workflow. A stable release is blocked unless its signed in-app updater is present, so the website does not point at a stranded installer. After you opt into automatic checks, Golavo checks GitHub once a day, shows an in-app notification when a newer stable release is found, and downloads only after you click Update now. You can always check manually in Settings → Updates.

Which option should I use?

Option	Requirements	Best for
Browser UI	Python 3.12+, Node 22+, source checkout	Developers, Linux, Intel Macs, and anyone who wants to inspect the code
macOS app	Apple Silicon Mac	The simplest Mac install; no Python or Node required
Windows app	64-bit Windows 10 or 11	The simplest Windows install; no Python or Node required

Unsigned first install

The desktop installers are not yet OS-signed. macOS Gatekeeper and Windows SmartScreen will warn the first time you open Golavo. This is different from in-app updates, which are cryptographically signed and verified before installation. Follow the installation guide and verify your manual download.

Verify a desktop download

Download SHA256SUMS.txt from the same release as the installer.

# macOS — run in the folder containing the DMG and SHA256SUMS.txt
shasum -a 256 -c SHA256SUMS.txt

# Windows PowerShell — compare the result with the matching SHA256SUMS.txt line
Get-FileHash .\Golavo_*_x64-setup.exe -Algorithm SHA256

The versioned Windows filename changes each release; use the exact name you downloaded. A checksum match detects corruption or an incomplete download. The checksum file is not itself signed, so download both only from the official Golavo releases.
