Automatic updates for your desktop app, from one dashboard.
Storage, signing, channels and a client that applies updates safely. All of it is already done, for Windows today and macOS and Linux next.
The release manifest is signed with your app's own key when you upload. The installer checks that signature before it touches a single file, so a tampered update never applies.
Every channel runs its own build: 42 to everyone on stable, 47 to your beta testers, 49 to your own team on canary. Protect a channel with a token or a password, and roll back by pointing it at an older build.
Each file is checked against its SHA-256, then swapped in as one step. If anything fails, the old version is restored.
Active devices, installs and which version each one runs, plus why people uninstall. Longer history on paid plans.
Add one step to a GitHub Actions workflow and every push uploads a build. A branch can get its own channel, so a build from a feature branch lands on beta without anyone clicking anything.
Need more than the design studio? We design and build a branded installer for you — your screens, your install steps, your roll-out — and ship it through the same signed update pipeline.
See what we buildNo servers to run and no pipeline to configure. You do the first and third steps in the dashboard.
Drop your app’s files into the dashboard, or let your CI upload them. Each file is hashed before it leaves your machine, and files we already store are skipped.
The release manifest is signed with your app’s key and the files are scanned before the build goes live.
Point stable, beta or any channel at the build. The next update check on that channel sees it.
Your installer verifies the signature, downloads the changed files and swaps them in without a reinstall.
Every plan ships signed updates to every install. Higher tiers raise the limits. Start with Indie for free and upgrade when your install base does.
Rare plan
For solo developers and side projects.
“Every studio started as a side project.”
Epic plan
For developers with a real product.
“Your name on the installer, not ours.”
Legendary plan
For teams shipping real products.
“Forged for teams who ship on Fridays.”
Unique plan
Unlimited scale, dedicated support and an SLA.
“One of a kind. Signed in writing.”
Pushing an update to a desktop app safely, especially on Windows, is a surprisingly painful problem with no clean off-the-shelf answer. So we built the infrastructure we wished existed.
Every update goes through the same checks, whichever plan you're on. Nothing is applied until it has proven where it came from.

Upload your compiled app to Omnihorn and press Build installer. The installer it produces checks your release channel, verifies the signature on the update, downloads only the files that changed, and applies them with a rollback if anything fails. You do not write update code.
Yes. You design the installer window in the dashboard, choose what launches after install, and Omnihorn builds a standalone setup.exe. It works with any framework because it ships your build folder; you do not need Flutter or Visual Studio on your side.
A channel, such as production or beta, points installed copies of your app at one build. Moving the pointer ships the build, and pointing it at an older build is a rollback. Channels can be public, password-protected or token-only.
Every release is signed with your app’s own Ed25519 key and the installer verifies it before any file is applied. See the security guide for exactly what is checked.
Windows is supported today. macOS and Linux installers are on the roadmap and are not available yet.
