Ship Signed Software with AI
Seal Your App lets AI agents build code-signed, notarized installers for macOS and Windows. Upload compiled binaries, get back a ready-to-distribute installer — no certificates, no developer accounts, no platform-specific tooling.
Get Started
Install the CLI and run sealapp init --agent. This creates a config template and installs the agent skill with complete step-by-step instructions for the entire workflow.
Install CLI + initialize project
# macOS/Linux curl -fsSL https://sealyour.app/cli/install.sh | sh # Windows irm https://sealyour.app/cli/install.ps1 | iex # Then: sealapp init --agent
The installed skill (SKILL.md) contains the full workflow: authentication, configuration, building, and user confirmation steps.
