Running in three steps
No setup wizard and nothing to configure — the time between this download and a running site is the time it takes to drag an icon.
- 01
Open the DMG and drag PortBay into Applications. The app is signed and notarized, so Gatekeeper opens it without warnings — no right-click ritual.
- 02
Add a project folder. PortBay reads the framework — Laravel, WordPress, Next.js, Vite, Node or static — and fills in the start command, port and hostname itself.
- 03
Press Play. Your site comes up at https://yourproject.test with a certificate your browser already trusts.
What it needs
PortBay is a native macOS app — no virtual machines, no container runtime sitting underneath it.
- macOS
- 11 (Big Sur) or later.
- Chip
- Apple Silicon — M1 or newer. Intel build coming soon; Windows and Linux are on the roadmap.
- Download
- One 76 MB DMG, or the Homebrew cask.
- Account
- None. The app runs entirely on your Mac.
Check the bits before you run them
Everything about this download can be verified — the code, the signature, the contents of the binary and every update after it.
Signed and notarized
Every release is built, signed, notarized and stapled by CI before it reaches GitHub — macOS verifies the app before it first opens.
Open source
The complete app — Rust core, interface and build pipeline — is public. Read the code that runs on your machine.
Signed updates
PortBay updates itself from GitHub releases and verifies every update against a published public key before installing it.
A bill of materials
Each release publishes an SBOM listing every dependency compiled into the binary, alongside the DMG on the releases page.
Download once. Press Play every day.
