Download Omnis Helix

Public download assets are published via the public GitHub repo omniscoder/helix-public-assets, not the private source repo.

Use the website downloads page as the source of truth for the currently promoted build. If you are pulling directly from GitHub, use the matching tag from:

Canonical Public Artifact Contract

The website release manifest currently promotes these core artifact slots:

Linux desktop zip: omnis-helix-linux.zip
Python wheel: helix_governance-<version>-py3-none-any.whl
Source distribution: helix_governance-<version>.tar.gz
Checksums: SHA256SUMS.txt
Build metadata: BUILD_META.txt
Extras: Windows/macOS desktop zips plus provenance sidecars when staged: omnis-helix-windows.zip, omnis-helix-macos.zip, SBOM-linux.spdx.json, SBOM-windows.spdx.json, SBOM-macos.spdx.json, SHA256SUMS.txt.asc, SBOM-linux.spdx.json.asc, SBOM-windows.spdx.json.asc, SBOM-macos.spdx.json.asc

If you are pulling from the public website asset host instead of the downloads page UI, the canonical direct URLs are:

https://downloads.helix-studio.com/releases/helix/<version>/omnis-helix-linux.zip
https://downloads.helix-studio.com/releases/helix/<version>/omnis-helix-windows.zip
https://downloads.helix-studio.com/releases/helix/<version>/omnis-helix-macos.zip
https://downloads.helix-studio.com/releases/helix/<version>/helix_governance-<version>-py3-none-any.whl
https://downloads.helix-studio.com/releases/helix/<version>/helix_governance-<version>.tar.gz
https://downloads.helix-studio.com/releases/helix/<version>/SHA256SUMS.txt
https://downloads.helix-studio.com/releases/helix/<version>/BUILD_META.txt
https://downloads.helix-studio.com/releases/helix/<version>/SBOM-linux.spdx.json
https://downloads.helix-studio.com/releases/helix/<version>/SBOM-windows.spdx.json
https://downloads.helix-studio.com/releases/helix/<version>/SBOM-macos.spdx.json
https://downloads.helix-studio.com/releases/helix/<version>/SHA256SUMS.txt.asc

If you are pulling directly from GitHub instead of the website asset host, the matching fallback URLs are:

https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/omnis-helix-linux.zip
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/omnis-helix-windows.zip
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/omnis-helix-macos.zip
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/helix_governance-<version>-py3-none-any.whl
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/helix_governance-<version>.tar.gz
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/SHA256SUMS.txt
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/BUILD_META.txt
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/SBOM-linux.spdx.json

https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/SHA256SUMS.txt.asc

Release bundles also publish the signing identity and provenance sidecars:

https://downloads.helix-studio.com/releases/helix/<version>/release-provenance.intoto.json
https://downloads.helix-studio.com/releases/helix/<version>/release-provenance.intoto.json.asc
https://downloads.helix-studio.com/releases/helix/<version>/release-signing-public-key.asc
https://downloads.helix-studio.com/releases/helix/<version>/release-signing-key-fingerprint.txt
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/release-provenance.intoto.json
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/release-provenance.intoto.json.asc
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/release-signing-public-key.asc
https://github.com/omniscoder/helix-public-assets/releases/download/<tag>/release-signing-key-fingerprint.txt

The website manifest still treats Linux as the primary desktop slot, but tagged public releases also publish Windows/macOS desktop zips and the provenance sidecars listed above.

Verify Integrity

macOS/Linux:

VERSION=<promoted-version>
BASE="https://downloads.helix-studio.com/releases/helix/${VERSION}"
curl -fLO "${BASE}/omnis-helix-linux.zip"
curl -fLO "${BASE}/SHA256SUMS.txt"
curl -fLO "${BASE}/BUILD_META.txt"
sha256sum -c SHA256SUMS.txt --ignore-missing

If present, you can also inspect the release SBOMs and armored checksum signature sidecars from the same base URL before trusting or mirroring the desktop bundle.

To verify the provenance bundle offline, pin the signing identity and then run the shared verifiers:

python tools/verify_release_signatures.py \
  --public-key release-signing-public-key.asc \
  --fingerprint-file release-signing-key-fingerprint.txt \
  --verify-path SHA256SUMS.txt \
  --verify-path BUILD_META.txt \
  --verify-path release-provenance.intoto.json \
  --json
python tools/verify_release_provenance.py \
  --statement release-provenance.intoto.json \
  --assets-dir . \
  --source-digest <git-sha> \
  --json

2-Minute Linux Trial

unzip omnis-helix-linux.zip -d omnis-helix-linux
chmod +x omnis-helix-linux/OmnisHelix
./omnis-helix-linux/OmnisHelix --no-gl --smoke-welcome

That smoke launch is the free proof lane. For the full Studio workspace, open the app normally and use Start 14-day evaluation from the welcome dialog when you want authoring, review, and pilot-package prep.

CLI + Python Package

If you want the helix / helix-cli command-line flow, offline pilot-package verification, and Python API:

python -m pip install -U helix-governance
omnis-helix --help
helix --version
helix-cli --version
helix-pilot-verify --help

If omnis-helix --help reports missing GUI dependencies, install the Studio extra shown by the entrypoint itself:

python -m pip install "helix-governance[studio]"
omnis-helix

To verify a Studio-generated pilot package offline:

helix-pilot-verify /path/to/helix_run_17_pilot_request_package.zip --json

If you are running from a source checkout instead of the installed package, use:

python tools/verify_pilot_package.py /path/to/helix_run_17_pilot_request_package.zip --json
