Dead links
That one button that 404s the moment someone clicks it.
Pre-flight check for macOS
Don't ship a broken launch.
Mizzen scans your site for the things you ship by accident: dead links, missing previews, exposed keys. It finds them before anyone else does.

No. 01 / failure modes
You tested the happy path. The launch breaks everywhere else.
The stuff that embarrasses you on launch day is never the stuff you were looking at. Mizzen watches the rest, live, before you publish.
Missing OG images
Your launch shared as a naked gray box on X, Slack, and iMessage.
Exposed keys
An API key or secret left sitting in your shipped source.
Broken social previews
Titles, cards, and thumbnails that render wrong everywhere they matter.
No. 02 / how it works
Clear to ship in three steps.
No dashboards to learn. No CI to wire up. Open the menu bar, scan, fix. That's the whole thing.
- 01
Point Mizzen at your site
Paste a URL into the menu-bar app. No setup, no account, no config files.

Run one scan
Mizzen sweeps your live site in seconds and grades it go / no-go.
- 03
Fix what it finds
Every issue comes back as a plain, fixable item, not a cryptic audit.
No. 03 / the toolkit
Small app. Thorough about your launch.
01
One-tap scan
A whole pre-launch sweep from your menu bar in about ten seconds.
02
Go / no-go score
A single, honest verdict on whether this thing is safe to ship.
