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:

The installed skill (SKILL.md) contains the full workflow: authentication, configuration, building, and user confirmation steps.
