Download Ordfoss

The early-access preview is free while Ordfoss is in development. It installs per-user (no administrator prompt), updates in place, and uninstalls cleanly from Windows Settings.

Released: August 5, 2026 · what's inside

Also available from GitHub Releases — the same file, byte for byte, with the same checksum.

Verify what you downloaded. Every release publishes the SHA-256 above so you can confirm the file is exactly what we built. In PowerShell: Get-FileHash Ordfoss-Setup.exe. Ordfoss installers are distributed only from dl.ordfoss.com and from our GitHub Releases page, both linked here — if you find one offered anywhere else, please tell us.

This preview build is not yet code-signed. Our certificate is being issued under the LoomWright Games LLC organisation identity through Azure Trusted Signing, and identity validation with Microsoft is still in progress. Until it completes, Windows SmartScreen will show a publisher warning on this installer. We would rather say so plainly than let it surprise you.

If your organisation's policy is not to run unsigned software — a reasonable policy — please wait for the signed build rather than working around it. We will announce it in the release notes, and you are welcome to email us and we will tell you the moment it ships.

System requirements

Windows 10 or Windows 11, 64-bit
About 300 MB of disk space
No internet connection required — the app is fully functional offline

Installing

Run the installer. It installs to your user profile — no administrator rights needed.
Launch Ordfoss, pick a theme, and open the sample project to look around.
Your projects are single .ordfoss files (double-click to open) — or plain folders of text files if you prefer working under version control.

Upgrading & uninstalling

Run a newer installer over an existing install and it upgrades in place — your projects and settings are untouched. Uninstall any time from Windows Settings ▸ Apps; your project files are never deleted.

For IT and security teams

If you are evaluating Ordfoss on a managed network, this is what you need to know without having to ask:

Publisher: LoomWright Games LLC, a Wisconsin limited liability company. See About.
Distribution: installers come only from dl.ordfoss.com and GitHub Releases, which serve the identical binary, over HTTPS. Each release publishes a SHA-256 checksum on this page.
Code signing: in progress via Azure Trusted Signing under the company's organisation identity; builds before that completes are unsigned and this page says so.
Installs per-user. No administrator rights, no services, no drivers, no scheduled tasks, and no changes outside the user profile.
Network behaviour: the application is fully functional offline. Its only self-initiated outbound request is an optional version check to dl.ordfoss.com, disabled in Preferences ▸ General. AI features are inactive until a user supplies their own provider and key, and then connect directly to that provider.
No telemetry, analytics or crash reporting. See the privacy policy.
Data at rest: projects are a single .ordfoss file or a folder of plain text on the user's own disk. Nothing is stored by us.
Security contact: [email protected] · security.txt

Need a completed security questionnaire, a software bill of materials, or a written statement for a vendor review? Email [email protected] and you will get one from the person who wrote the code.

Early access means early. Ordfoss is in active development. Backups matter to us: the app snapshots your project automatically on every open, keeps version history, and recovers cleanly from crashes — but do keep copies of work you can't lose, as you would with any preview software.
