Installation

Sirius runs natively on the three desktop platforms. Pick the right installer and verify the SHA-256 signature before running it.

Download

OS	Format	Notes
Windows 10+	.exe	Signed installer, autoupdates
Linux	.deb, .rpm, AppImage	AppImage works on any modern distro
macOS arm64 + x86_64	.dmg	Notarized

Latest version + checksums: sirius-ide.com/download.

Verify the signature

# Linux / macOS
shasum -a 256 sirius-1.0.0.dmg
# Expected: <hash from /download page>

# Windows (PowerShell)
Get-FileHash .\Sirius-1.0.0-setup.exe -Algorithm SHA256

If the hash differs from the value on the download page, do not run the installer — re-download it from the official site.

Install from source

For contributors and security-conscious users:

git clone https://github.com/sirius-ide/sirius
cd sirius
python -m venv .venv
source .venv/bin/activate         # PowerShell: .venv\Scripts\Activate.ps1
pip install -r requirements.txt
python -m sirius

Once the public release lands you’ll also be able to run:

pip install sirius-ide
sirius
